REPORT OF THE CHEMICAL SURVEY
of the
WATERS OF ILLINOIS
Andrew Sloan Draper, LL. D.,
President of the University of Illinois.
SIR: Herewith I submit a report of the work of the
Chemical Survey of the Water Supplies of Illinois, covering
the years 1897 to 1902, inclusive. As was stated in my pre-
liminary report, published in 1897, portions of which are in-
corporated in the present report, the aims of the survey in-
clude the determination of the present sanitary condition of
the water supplies drawn from the lakes, the streams, and the
wells of the State; the determination of the normal condition
of uncontaminated waters; the formulation of local standards
of purity based upon the results of analyses of water derived
from unpolluted sources; the provision of such means as shall
afford to citizens of the State opportunity to obtain immedi-
ate information regarding the wholesomeness of the potable
waters in which they are directly interested; and in general
the prevention of the development and dissemination of dis-
ease from the use of impure water.
The press of work in certain of these directions has been
so great that comparatively little has been accomplished in
others, and a mass of data concerning the normal condition
of ground waters must be left for digestion and discussion at
some future time.
The present report may be broadly divided into three
parts, namely:
1. A brief consideration of the sanitary condition of the
ordinary ground waters and matters relating thereto. Accom-
panying this there is a paper upon "The Geology of Illinois
as Related to Water Supplies," by Charles W. Rolfe, Professor
of Geology in the University.

2.
Results of the mineral analysis of some four hundred
and sixty samples of water mainly from wells of considerable
depth.
3. A report of the investigation of the surface waters of
the State, relating chiefly to the Illinois River and some of
its tributaries.
Most of the routine work of these investigations has
been conducted by Mr. C. V. Millar, M. S., and Mr. R. W.
Stark, B. S., to whom special commendation is due for the
continued interest, the skill and the unfailing zeal with which
they have furthered the purposes of the Survey. At various
times we have further been ably assisted by Mr. F. C. Koch,
M. S.; Mr. E. P. Walters, B. S.; Mr. A. D. Emmett, B. S.;
and Mr. A. L. Marsh.
Respectfully submitted,

Professor of Chemistry.
SOURCES OF WATER SUPPLY.
7
THE WATER SUPPLIES OF ILLINOIS.
The available sources of water supply in this State are
practically limited to rain water, low land surface water fur-
nished by streams and lakes, and ground waters obtained
from wells of greater or less depth.
The water derived from each of these sources differs
widely in character from those derived from the others, and
again within each of these classes, including even the first,
there are found the widest variations in character and qual-
ity, the result usually of local conditions.
Approximately one-half of the inhabitants of the State,
including the citizens of Chicago and those of certain of the
larger towns, drink surface waters drawn from Lake Michi-
gan or from various streams. The other half, including the
people of the smaller towns and the rural districts, drink
water drawn from wells, some of which derive their supply
from rock strata, but of which by far the greater mumber are
supplied with water from the earth deposits overlying the
rock, which deposits cover almost the entire surface of the
State, range in thickness from a few feet up to two hundred
and fifty feet or more and consist chiefly of glacial detritus
or drift.
In certain localities, particularly in the extreme north-
western section and in the southern extremity of the State,
where ground waters are in general not easily obtainable,
rain water is quite extensively used for drink, but elsewhere
in Illinois it is rarely used for this purpose, although by the
exercise of care in its collection and preservation, it would be
found far more satisfactory and wholesome than the ground
waters and surface waters which are usually drank.
Rain Water, if caught in its original condition and prop-
erly preserved, doubtless constitutes the purest water which
nature affords. Pure rain water, however, is but rarely ob-
tained, because the care and attention requisite in order to
8

collect it in uncontaminated condition are not often devoted to
the purpose, nor even generally recognized as really necessary.
Rain in falling to the earth washes from the air some or
all of the various impurities which the atmosphere contains,
so that the water precipitated during the forepart of a rain
storm usually contains considerable quantities of foreign sub-
stances, both mineral and organic. In addition to the objec-
tionable gases emanating from fires, from manufacturing es-
tablishments, from decomposing refuse matters, etc., the im-
purities include numerous solid substances of which the most
important are soot, dust from the fields, roadways, etc., and
various sorts of germs. Furthermore, the roofs which serve
as collecting surfaces are usually soiled with soot, dust blown
from the roadways, the excrement of birds, decaying leaves,
etc. Ordinarily no serious effort is made to prevent these
matters from entering the cistern, but commonly the cistern
is provided with a filter wall of soft brick, which is expected
to remove from the water substances which ought never to be
contained in that water which is allowed to enter the cistern.
The ordinary cistern filter, as commonly managed or
rather neglected, frequently is almost worse than useless, in-
asmuch as it soon becomes surcharged with the matters which
it has removed from some of the water, and then instead of
purifying the water which subsequently passes through, often
becomes a source of offence if not of danger.
The rain water which is collected during the latter part
of a shower, after the air and roof have been thoroughly
washed, is comparatively pure; nevertheless it still contains
small quantities of foreign substances which may accumulate
and may become a menace to health, unless the cistern, and
especially the filter, be kept scrupulously clean.
The rain pipes of most residences are nowadays provided
with cut-off valves which enable one to reject the first wash-
ings of the atmosphere and the roofs, but these valves are
generally left in a condition which may perhaps appropri-
ately be designated as a state of noxious desuetude.
Surface WATERS: In general, water taken from lakes,
from streams or from the ground, when these sources of sup-
ply are in their original or natural condition, is perfectly
wholesome and unobjectionable; but with increasing popula-

tion and longer occupancy of the ground, the conditions
change and contamination becomes inevitable.
Our water courses are natural drainage channels; they of
necessity receive the drainage of all towns and villages and
dwelling places situated within their respective water shed
areas, so that nearly if not quite all of our streams now con-
tain sewage.
But the dangerous impurities contained in the waters of
our streams come by no means wholly from the discharge of
sewage into them.
The surface wash carried into our water courses by the
"run off," i. e., that portion of the fallen rain which flows
over the surface of the ground directly into streams and lakes,
periodically introduces more organic matters into these
sources of water supply than does sewage.
Moreover, these organic matters, including as they do,
the periodic storm washings of the streets and alleys, of barn
yards and pig pens, of slaughter house surroundings and
garbage dumps, and the by no means less objectionable slops
and other refuse which an inattentive public throws or per-
mits to be thrown almost anywhere and nearly everywhere
except in the front yard, constitute fully as dangerous a
source of pollution as do the organic matters of sewage itself,
notwithstanding the fact that the organic matters conveyed
to streams by the run-off consist very largely of substances
of vegetable origin, which are far less easily susceptible to
that class of agencies which quickly occasion the putrefactive
and other decompositions of the animal wastes which consti-
tute the more characteristic components of ordinary sewage.
The organic matters from all or any of these sources go
partly into solution in the water, but are for a time at least
held mainly in suspension and together with suspended min-
eral matters) impart to the water a disagreeable turbid ap-
pearance; they soon begin to undergo decomposition if indeed
they are not already in an active state of putrefaction when
they enter the water, and in consequence of these changes,
odors and tastes develop which are offensive to the senses
and detrimental to health. However, the particular danger
encountered in the use of sewage laden waters for drink lies
not in the action of the dead organic wastes, which consti-
10

tute by far the greater part of the impurities, or the ordinary
products of their decomposition, but in the presence of those
minute living organisms which either themselves or through
the products of their vital activities, the toxines, etc., are the
specific causes of disease. As the fresh sewage of a town is
probably never free from disease germs, it is fortunate that
the conditions prevailing in such bodies of water as are avail-
able for water supply are not favorable to the growth and
multiplication of the disease germs which are contributed to
sewage by fecal discharges. Consequently the disease germs
once introduced into such waters through pollution by sew-
age do not increase, but, either through the lack of the proper
food or the absence of other necessary conditions, or, because
in the struggle for existence they are crowded out by the
hardy and harmless bacteria which find their natural habitat
in surface waters, they gradually die and in course of at most
a few weeks disappear entirely.
Since the disease germs do not under these conditions
thrive and multiply, but on the contrary soon become extinct,
the danger attending the use of such waters for drink is de-
pendent upon the introduction of fresh supplies and is ever
present because of the continual inflow of germ-laden sewage.
But dejecta containing disease germs may enter water
supplies into which no sewerage system discharges. The ease
with which any body of water may be infected and may be-
come the means of distributing disease, by the act of an indi-
vidual who has the disease in so mild a form that he is not
confined to the house or the hospital, or by one who is in the
earlier stages of the disease or is convalescent, seems ominous
when one reflects upon the fact that a single cubic centimeter
of the urine of a typhoid fever convalescent has been found to
contain *172,000,000 germs, and that a single gram of fecal
discharge from a typhoid fever patient has been found to con-
tain †1,000,000,000 to 2,000,000,000 germs. A passenger up-
on a boat, a bather, a fisherman or a pleasure seeker wander-
ing along the bank may easily become the means of causing
an epidemic. In a number of well authenticated cases it has
been shown that the fecal discharges of a single individual

suffering from typhoid fever, having been thrown upon the
ground, have thence been washed by falling rain or melting
snow into a nearby stream which, further down in its course,
served as a source of water supply, and have caused serious
epidemics resulting in the loss of many lives. The dangers
from these various sources are so real, so serious and so omni-
present, they constitute so neverceasing a menace to health,
that it would seem to be but the plainest duty and certainly
the wisest and safest course to urgently advise, if, indeed, not
to insist, that none of the ordinary surface waters of this
State shall be used for drink unless they be first efficiently fil-
tered, or in cases where filtering is impracticable, they be
rendered innocuous and safe by thorough boiling.
Ground WATERS: More than two million of the inhab-
itants of this State drink water drawn from about five hun-
dred thousand wells, the greater number of which are of in-
considerable depth, receive seepage from all of the pervious
strata which they penetrate, from the surface down, and in
consequence of the ease with which polluted drainage finds
way into them, constitute an ominous and constant men-
ace to the health of those who use them.
its
Every year there occur, in many of the towns and vil-
lages of this State, destructive outbreaks of typhoid fever,
which are almost invariably traceable to the use of water
drawn from polluted shallow wells, wells the character, loca-
tion and surroundings of which, often exhibit at once to the
competent sanitary inspector, the dangers to which the un-
suspecting, or oftentimes carelessly indifferent, users expose
themselves. A very considerable proportion of the public is
widely awake to the danger attending the use of surface
waters into which sewers are seen or otherwise known to dis-
charge, but altogether too little attention is given to the con-
ditions and facts which result in the pollution of ground
waters.
The common belief that filtration through the ground
purifies water is of course well founded, but the conditions
upon which the efficiency of ground filtration depend, are far
too often either not understood or are ignored.
The individual who, alive to the danger and aware of
the conditions which ensure his security, sees to it that the
12

wastes of his own household are so disposed that they cannot
pollute the water supply, is too often at the mercy of a more
ignorant or less careful neighbor, who has a cesspool or a
privy vault, or throws household wastes upon the ground in
too close proximity to his own and to his neighbor's well.
It must be borne in mind that the purifying power of the
soil is limited and that earth which is kept saturated with
drainage from the refuse matters, soon becomes overburdened
and fails to remove from the percolating fluids those constit-
uents which are the real sources of danger.
The earth agencies which mainly bring about the decom-
positions and oxidations, resulting finally in the complete de-
struction of organic matters and their conversion into harm-
less organic substances, are the myriads of bacteria which in-
fest the surface soil strata. Unless they be supplied with
free oxygen either by admission of air into the interstices of
the soil, or by saturation of the waters of the soil with air or
oxygen, the complete oxidation of the organic matters cannot
be effected.
It is chiefly the exclusion of air or oxygen from the soil
by the drainage with which the earth is saturated, that pre-
vents the effective and complete action of the bacteria of the
soil, which otherwise serve as natural scavengers.
Ground filtration of polluted water, in order that it be ef-
fective, must be in some degree intermittent, that is, the fil-
tering material must be frequently renewed, either by actual
replacement or by exposure to the oxidizing action of air.
This principle, the basis of successful practice in the man-
agement of filtration plants for the purification of polluted
water supplies, and likewise the basis of one of the best of
the modern methods of sewage disposal, is not generally ap-
prehended by those who depend for their water supply upon
shallow wells, although it applies with equal force to the pro-
cess of soil-filtration upon which they place reliance for the
removal of all objectionable matters from the liquids which
find their way through the soil to the wells. Because the
water from such wells is in general clear, sparkling, cool, and
of agreeable taste, it is popularly supposed that it is whole-
some; and the continued use of such waters for drink during
many years is frequently cited as an argument in their favor.
POLLUTION OF GROUND Waters.
13
It must be remembered that sewage from healthy sources
may, in a diluted state, be drank with impunity. Very few
people would choose to do this, yet oftentimes many do so
unwittingly in their use of shallow well water.
The danger lies in the fact that the refuse, the drainage
from which contributes to the supply of the well, may at any
time receive dejecta from diseased beings, and the well in con-
sequence become a possible means of distributing the disease.
Although matters which are offensive to the senses are
commonly either mechanically removed or are oxidized, or are
otherwise rendered innocuous during the passage of sewage-
laden waters through the soil, yet the danger instead of be-
ing thereby lessened is frequently increased by reason of the
false security which this merely apparent purification engen-
ders. Germs in general, but more particularly those germs
which are the specific cause of disease, are known to pass for
considerable distances through certain water bearing soil
strata and to remain in the palatable but deadly infusion
from which most of the other organic substances have been
removed.
Contamination of the water supply may occur in the most
unsuspected ways. Sometimes water bearing strata which
supply wells or springs so situated as to be free of any possi-
ble local contamination, outcrop at a distance, but at places
where the surface is polluted, or they may receive their supply
from polluted surface waters.
The celebrated epidemic of typhoid fever at Lausen,
Switzerland, in 1872, was caused by the pollution of a moun-
tain stream, some of the water from which, it was subse-
quently shown, passed underground for a mile through a
mountain of glacial detritus to issue in part at a spring which
served as one of the sources of supply for the village. It was
shown unmistakably that the water of this spring caused the
epidemic among the users, and it was shown conclusively that
the infection of this water was caused by the dejecta of
certain typhoid fever cases at a farm-house a mile or two
away across the mountain being thrown into the brook at
a point above that at which there proved to be an under-
ground connection with the spring. In this case the typhiod
fever germs passed for at least a mile through earth strata.
14
WATER SUPPLIES OF ILLINOIS.
The earth strata in many portions of this State are of
such character and so variously distributed and arranged that
the passage of waters from contaminated surface sources
underground to wells and springs at short distances easily
occurs, and there is every reason to believe that infection with
typhoid fever germs is frequently occasioned among the in-
habitants of this State in this way. In several parts of the
State the rock strata which lie at or near the surface and yield
a supply of water by means of wells of comparatively little
depth, are so broken that drainage easily passes through rifts
and cracks directly to the wells without being freed of germs.
Numerous instances of the dissemination of disease to the
extent of producing great loss of life by epidemics, by the use
of well or spring waters which were highly prized because of
pleasant appearance and taste, are to be found recorded in
sanitary literature.
The facts involved in the foregoing statements are well
understood by physicians and scientists, and are so thoroughly
recognized by boards of health, that most of the greater
municipalities have provided means for the examination and
control of their water supply and the disposition of sewage.
The department of health of the city of Chicago has provided
for the vigilant inspection and the constant investigation of
the water supplied to the people of the metropolis. In a num-
ber of the larger towns of the State the water supply is
occasionally made the subject of a sanitary examination, but
no extensive investigations of the ground waters of this State
have hitherto been made; although, contrary to popular beliet,
diseases arising from, or distributed by, impurities in the
water supply are much more prevalent in the smaller towns
and the country districts than in the large cities.
In establishing the chemical survey of the waters of the
State, the trustees of the University made provision for exam-
ination into the sanitary condition of any drinking water
used by citizens of Illinois, and thus afforded opportunity for
protection of the inhabitants of the towns, the villages, and
the rural districts, from the unwitting use of impure drinking
water and the attendant consequences.
The extent to which advantage has been taken of this
provision is indicated by the following table which shows the

WATER SUPPLIES OF ILLINOIS.
Each of these thirty-seven hundred samples of water has
been carefully examined, and a separate report and recom-
mendation concerning each has been given to the parties by
whom the waters were sent to us. In only a very few in-
stances have more than one sample been sent to us from any
one of these sources, so that the data and the recommenda-
tions made are, in most cases, of but temporary and local
interest, and consequently are not published in this report.
These waters have come from all parts of the State, and,
while it would be of but little importance here to name the
various localities, it may be of interest to note the fact that
the samples have been sent to us from four hundred and
seventy-eight towns and hamlets and that only two counties of
the State are unrepresented. The map herewith gives a
fair idea of the distribution of the localities in question.
Accompanying most of the samples of water from ordi-
nary shallow wells, there came to us the statement either that
cases of typhoid fever existed in the families which used the
water, or that this disease was prevalent in the neighborhood.
Careful consideration of the analytical data, the character
and depth of the wells and the nature of the surroundings
led us to the conclusion that a large proportion of the wells
in question received drainage from refuse animal matters,
although in general the removal or the oxidation of the
organic matters seemed to be quite complete. Nevertheless,
since the conditions in most cases appeared to be such that
the soil filtration might at times be incomplete, the reports
made upon such waters included the recommendation that the
water should be used for drink only after efficient filtering or
boiling, or that the use of the water of the well for drink be
discontinued at least until steps should be taken to prevent
any possible access of animal drainage in unoxidized condition.
It seems quite evident to us, that, although the dissemi-
nation of typhoid fever may often be effected in ways not
directly ascribable to the use of contaminated water, yet the
use of the water of shallow wells, situated as nearaly all of
them are in close proximity to sources or deposits of animal
refuse, is chiefly accountable for the widespread prevalence
of typhoid fever in the smaller towns and the country districts
of this state.

WATER FROM THE DRIFT.
17
So far as the unwholesomeness of the waters of the
ordinary shallow well is concerned, the conditions are steadily
becoming worse, and must necessarily continue so to do, for
as the population increases, naturally the wastes of habitation -
likewise increase, while the methods of disposition of such
wastes, so far at least as concerns the country places and
small towns, remain the same. For the individual household,
it would be by far the best plan to entirely abandon the use of
shallow wells and to use, for drinking purposes at least, only
the water obtained from deep strata by means of driven wells
tightly cased up so that none of the drainage of the strata
lying near to the surface enters. Such wells, while some-
what more expensive, are highly advantageous in that the
water which they supply is in most cases entirely unobjec-
tionable so far as the dissemination of water-borne infectious
diseases is concerned, for as a rule their water supply is
drawn from sources which underlie impervious strata of clay
so that none of those constituents of drainage which cause the
spread of disease can reach them. The chief objection to the
use of such waters arises from the fact that many of them
are of unpleasing appearance, that is, are turbid when drawn
or soon become so upon exposure to the air, and frequently
they possess a taste which is unpleasant to those not accus-
tomed to their use; this is particularly true of waters drawn
from the drift.
WATER FROM THE DRIFT.
Nearly the whole surface of our state is covered with
deposits of glacial detritus, the drift and the loess, to
depths of from ten to one hundred and fifty feet, in some
parts even to a depth of two hundred and fifty feet or more.
These deposits include strata of sand, gravel, and clay, in
almost infinite variety of character, fineness, and states of
admixture with each other, and range from pure, clean rock
fragments, silica, etc., and pure kaolin, on the one hand, to
indeterminate mixtures containing large proportions of
organic matters, the remains of vegetable life, on the
other.
Thronghout large areas of the State, ancient surface
soils, peat beds, and the like have been covered by consid-
18
WATER SUPPLIES OF ILLINOIS.
erable deposits of sand, gravel, clay, etc.; in many localities
several such buried surface soils containing the remains
of the organic matters incident to the luxuriant vegetable
growths of past ages, lie one below another, separated by
intervening drift deposits which range from several feet to
fifty or sixty feet in thickness.
Many of the drift strata are water-bearing and a large
proportion of the citizens of Illinois outside of the larger
cities drink water drawn from wells which are sunk more or
less deeply in the drift. These waters in normal condition
present almost endless variety in minor characteristics,
depending of course upon the composition of the deposits
with which they have been in contact, but they fall natur-
ally into two groups with reference to their leading qualities
and the relative proportions of their several nitrogenous con-
stituents. These two groups may be designated as shallow
drift waters and deep drift waters respectively, since, in
general, the differences manifested depend upon the depth
from which the waters are drawn.
NORMAL SHALLOW DRIFT WATERS contain the various
salts and other substances which have been leached from
the upper soil, essentially in unchanged condition, i. e.,
they contain chlorides, sulphates, carbonates, and silicates
of calcium, magnesium, potassium, and sodium, with minute.
quantities of iron and aluminum compounds, together with
considerable quantities of nitrates, but only minute quanti-
ties of saline ammonia and albuminoids; organic matters
are almost entirely absent. Nitrites are frequently present
in notable quantity.
NORMAL DEEP DRIFT WATERS contain in general the
same mineral salts as the shallow waters but usually the
quantity of iron is considerable, and the nitrates are either
entirely absent or present in but minute quantity, while free
ammonia is abundant and albuminoids are present in com-
paratively considerable quantities.
"Oxygen consumed" is high, and the water residue
blackens upon being heated, showing that much organic
matter is contained.
In appearance and in palatability the two classes of
waters present marked differences.
DEEP DRIFT WATERS.
19
The waters from shallow wells are well aerated, and are
clear, sparkling, cool, and of agreeable taste; those from
the deeper wells, on the other hand, contain little or no
oxygen, possess in many cases a disagreeable taste due to
the presence of marsh gas, accompanied occasionally by
minute quantities of sulphuretted hydrogen, and are either
turbid or become turbid quickly on exposure to air, owing
to the oxidation of the iron carbonate which they contain
and the consequent precipitation of insoluble ferric com-
pounds. The precipitating particles are often so minute as
to be at first indistinguishable except from the color which
they impart to the water, but after a short exposure to the
air the water becomes opalescent, then decidedly turbid;
finally a brown deposit similar to iron rust is produced, and
after this has separated the water becomes clear and color-
less.
Waters of this class soon become infested with the mi-
croscopic filamentous plant crenothrix. This organism is not
especially deleterious to the health, but it brings about the
separation of the iron from the water and its deposition as
rust like ferric hydroxide in and upon its own filaments, the
growths causing a marked turbidity of disagreeable appear-
ance and often producing unpleasant tastes and odors. Fre-
quently it grows so luxuriantly in the distributing system as
to clog the pipes with masses of dirty greenish or brown
colored, iron impregnated vegetation. At times, the growths
becoming loosened from the pipes, cause the liquid flowing
from faucets to have the appearance of a fluid mud of iron
rust rather than that of water.
Although these unpleasant characteristics of the deep
drift waters give rise to much prejudice and objection to their
general use for drink, nevertheless, from the sanitary
standpoint, they are usually to be preferred to the clear and
palatable waters of the shallow wells, since the evidence
of numerous analyses shows, that they are far less subject
to pollution with refuse animal matters than are the latter,
while the organic matters which they contain are derived
from the buried vegetable remains referred to above, and
are comparatively harmless.
In the interest of the public health, it would be far the
20

best for the people of even the smallest towns, to use for
drinking purposes, only the water supplied by one general
plant, the sanitary condition of which could be and should be
thoroughly and periodically investigated by experts acting
under the direction of a water commission or the State Board
of Health.
THE CHEMICAL EXAMINATION OF WATERS.
The general purpose of the chemical analysis of potable
waters is well understood by the public to be intended in some
way for the determination of the question of their purity
and wholesomeness, but nevertheless, much misconception
exists regarding the method of arriving at an opinion, and
the significance of the analytical data. It must be under-
stood that the results of a chemical examination of a water
are not in themselves sufficient to indicate the character of
the water in any ordinary case. In the assay of gold ore,
the determination of the quantity of gold is all that is
necessary, for the value of the ore depends directly on the
amount of the precious metal contained, and this is directly
represented by the analytical result. The data resulting
from a water analysis, on the other hand, require interpre-
tation, and it is essential that the one who is to interpret
shall have complete information regarding the history of the
water, its source, the surroundings, etc.; also, in case of a well,
the nature of the strata from which the water comes, as well
as the overlying strata, and in fact, as complete informa-
tion as it is possible to obtain, Even with this information,
the formation of a correct conclusion is in many cases a dif-
ficult matter, and is ordinarily entirely beyond the powers
of the layman.
A wholesome water from a certain source may contain
such quantities of the varions constituents as would, if found
in the water from a different source, serve to entirely con-
demn the latter. The significance of the results depends
usually directly upon the source of the water.
Further, certain substances, the determination of which
is most important, are present usually in but minute quan-
tities in potable waters, and these quantities are very easily
increased by the use of improper methods and vessels in
COLLECTION OF SAMPLES.
21
taking the sample. Some of the constituents of the water
readily change on standing, especially if the sample be-
comes warm and is exposed to the light. Accordingly, in
providing for the chemical examination of waters for the
citizens of the State, it was necessary to make certain
that the samples should be collected with the utmost care
and in vessels properly cleaned, as otherwise the results of
the analyses would be valueless. In the case of each collec-
tion which is to be made, whether it is a part of our general
survey or at the request, and for the immediate information
and benefit of individual citizens of the State, the method
of general procedure is precisely the same.
Glass stoppered bottles of one gallon capacity are used
for collections. These are cleaned by means of a solution
of potassium bichromate in diluted sulphuric acid, then
rinsed with fresh ammonia-free distilled water, drained,
and the stoppers secured in place by being covered with.
clean canvas or rubber cloth tied down tightly. The bottles
are then packed in wooden cases with open tops and shipped
to the collector. An envelope shipping tag containing printed
directions for the collection of the sample and a blank cer-
tificate to be filled out by the collector with all necessary
information concerning the sample, is tied to the neck of
each bottle. When samples for bacterial examination are to
accompany those intended for chemical analysis, the bottles
are packed in a closed case in which there is a large galvan-
ized sheet iron box to hold ice. The directions and certifi-
cates used are as follows:

22
WATER SUPPLIES OF ILLINOIS.
CHEMICAL LABORATORY UNIVERSITY OF ILLINOIS
INSTRUCTIONS FOR COLLECTING SAMPLES OF WATER FOR ANALYSIS.
1. From a Well. Water should be pumped out freely for a few
minutes before it is collected. The bottle is then to be placed in such
position that the water from the spout may fall directly into it, and
rinsed out with the water three times, pouring out the water com-
pletely each time. It is then again to be placed under the spout,
filled to overflowing, and a small quantity poured out, so that an air
space of about an inch shall be left under the stopper. The stopper
must be rinsed off with flowing water, inserted into the bottle while
still wet, and secured by tying over it a clean piece of rubber cloth or
canvas. The ends of string must be sealed on top of the stopper.
Under no circumstances must the inside of the neck of the bottle or the
stopper be touched by the hand or wiped with a cloth.
2. From a tap. Allow the water to flow freely from the tap for a
few minutes, and then proceed precisely as directed above.
3.
From a Stream, Pond or Reservoir. The bottle and stopper should
be rinsed with the water, if this can be done without stirring up the
sediment on the bottom. The bottle, with the stopper in place, should
then be entirely submerged in the water and the stopper taken out,
at a distance of twelve inches or more below the surface. When the
bottle is full, the stopper is replaced (below the surface, if possible,)
and finally secured as above. It is important that the sample should
be obtained free from the sediment at the bottom of a stream and
from the scum on the surface. If a stream should not be deep enough
to admit of taking a sample in this way, the water must be dipped up
with an absolutely clean vessel and poured into the bottle after it has
been rinsed. The sample of water should be collected immediately before
shipping by express, so that the shortest possible time shall intervene be-
tween the collection of sample and its examination.
The accompanying "Certificate" must be filled out carefully and
enclosed in the envelope shipping tag.

In case of turbid waters, which have come mainly from

on evaporation, lose on ignition, nitrogen as albuminoid am-
monia, and oxygen consumed, both with the water in its
original condition and after careful filtration, in order to dis-
tinguish between constituents contained in solution and those
held in suspension.
Wherever it has seemed to be of importance, determina-
tions of the hardness and the degree of alkalinity have been
made.
In a very large proportion of the surface waters examin-
ed, the total organic nitrogen has been determined by the
Kjeldahl process, both in the original water and in a filtered
portion of the same.
The dissolved gases, more especially the dissolved oxygen,
have been determined in several hundred samples.
In addition to the sanitary examination of some 10,833
samples of water from all sources, we have made quantitive
analysis of the mineral constituents of more than 450 sam-
ples of ground waters.
METHODS OF PHYSICAL AND CHEMICAL EXAMINATION.
When the samples are received at the Laboratory, a serial
number is immediately placed upon each bottle and upon the
tag or certificate which accompanies it, then the rubber cloth
which covers the stopper is removed, the stopper and neck of
the bottle cleaned, and, after withdrawing the stopper, some

of the water is so poured out as to rinse off the lip of the bottle.
After noting the turbidity, but before beginning the
analysis, the sample is thoroughly shaken, and every effort
made to keep all solid matters in suspension while the por-
tions are being taken for the various determinations. Ground
waters are almost always so clear that ordinarily no attempt
is made to determine suspended matters. If the water is dis-
tinctly turbid, which is generally the case with our river
waters, certain determinations as noted above, are made upon
the filtered water. For this purpose nearly half of the sample
is immediately filtered through heavy Swedish filters, which
have been previously washed with nitrogen free water. Often
it is necessary to filter more than once.
The nitrites are always determined immediately upon
reception of the sample in the laboratory; the determination
of nitrates, the ammonias, and oxygen consumed are also
begun immediately, and the others are started as soon as pos-
sible. Some of the determinations, as the total solids and
chlorine, are ordinarily not finished until several days after
that upon which the sample was received in the laboratory.
In the tables of results, the date of collection indicates
the date placed upon the collector's tag at the time the sam-
ple was taken. The date of analysis refers to the time of the
receipt of the sample in the laboratory, which also invariably
represents the day upon which the analysis of the sample
was begun.
TURBIDITY AND Sediment. The amount of sediment and
the degree of turbidity are noted from mere visual inspection
at the time the sample is received and again in a portion of
the sample after standing over night, and is indicated in the
tables of results by the very approximate terms, "slight,"
"distinct," "decided," and "much," to indicate the degree of
turbidity, and the terms, "very little ""little," "considerable,"
and "much," to indicate the relative quantities of sediment.
A more definite idea of the amount and nature of the sus-
pended matter is, of course, to be had from the figures recorded
in the respective columns under the general headings--"Total
Solids," "Loss on Ignition," "Oxygen Consumed," "Albumi-
noid Ammonia," etc.
ODOR.-Note is made of the odor after thoroughly shaking
26
WATER SUPPLIES OF ILLINOIS.
the water in the bottle just before the portions of the sample
are poured out for the determination of the various constitu-
ents, and the result of the observation is roughly expressed
as "oily," "gassy," "musty," "none," etc. In some cases the
odor is observed again after heating a portion of the water
nearly to boiling.
THE COLOR.The color of the water is determined by
comparison with the color developed in the ammonia standard
solution used in nesslerization; the surface waters of this state
must, in most cases, be filtered for this purpose.
The figure recorded in each case represents the volume of
standard ammonium chloride solution required to develop the
same tint as that possessed by the water, when diluted to
fifty cubic centimeters with ammonia free water and treated
with the usual amount of nessler reagent. That is, the color
recorded as 1, represents the color developed by nesslerization
of a solution containing one cubic centimeter of the standard
ammonic chloride solution diluted to fifty cubic centimeters
with ammonia free water, or, in other words, fifty cubic cen-
timeters of a solution which contains ammonic chloride
equivalent to one one-hundredth of a milligram of nitrogen.
The tubes employed are those used in the regular nessleri-
zation; they are of colorless glass, ten inches in extreme
length and seven and three fourths inches high to the mark;
the bottoms are ground smooth and polished.
TOTAL SOLIDS.-For the determination of the total
solids, to two hundred and fifty cubic centimeters of the
water, five cubic centimeters of a four-tenths per cent sodium
carbonate solution are added, and the liquid evaporated to
dryness in a platinum dish upon the water bath. When dry,
the dish and its contents are placed in an air bath, kept at
180° Centigrade, and heated until the weight is essentially
constant; the time of heating ordinarily being one hour. Al-
lowance is, of course, made for the quantity of sodium car-
bonate added before evaporation.
LOSS ON IGNITION.-The loss on ignition is determined
by heating the residue from evaporation in a radiator to low
redness. No attempt is made to entirely burn away all car-
bonaceous matter contained in the residue and the residues
frequently are quite dark in appearance from presence of
METHODS OF ANALYSIS.
27
minute particles of carbon. Record is made of any odors
resulting from decompositions caused by the ignition, and
also of colored fumes from decomposition of nitrates, which
latter occurs, however, only when rather excessive quantities
of nitrates are present, as in some shallow well waters.
CHLORINE. The chlorine determinations are made by
the ordinary standard process by titration with silver nitrate
solution. The indicator employed is potassium chromate of
five per cent strength; one cubic centimeter of the solution
being used with each lot of water titrated. The silver nitrate
solution is of such strength that one tenth of a cubic centimeter
represents one part of chlorine in a million parts of water,
when fifty cubic centimeters of the water are used for the de-
termination. The standard silver nitrate solution is checked
by titration against a standard sodium chloride solution.
The end point is in all cases determined by close com-
parison with a blank. Fifty cubic centimeters of water are
ordinarily taken for the determination, but in case there is
reason to suppose that the water contains less than ten parts
of chlorine per million, a larger quantity is used. In all such
cases, two hundred and fifty cubic centimeters or more are
employed. To the measured water, five cubic centimeters of
sodium carbonate solution (four grams Na, CO, to the liter)
are added, and the liquid concentrated, the final volume being
brought to fifty cubic centimeters before the determination is
ma de. In cases of some artesian well waters and others which
contain considerable chlorine, a smaller quantity of the sam-
ple is diluted with chlorine free water to fifty cubic centime-
ters before titrating.
OXYGEN CONSUMED, -One hundred cubic centimeters of
the water are measured into an Erlenmeyer flask of two hun-
dred and fifty cubic centimeters capacity, two cubic centi-
meters of pure concentrated sulphuric acid are added, and
then ten cubic centimeters of standard potassium permanganate
solution, of which one cubic centimeter is equivalent to one-
tenth of a milligram of oxygen. The flask is then so placed
in boiling water that the level outside of the flask is above
that of the liquid within. In this way the temperature with
in the flask is brought up almost to that of the water, which
is kept briskly boiling, in the bath itself, and any considera-
28
WATER SUPPLIES OF ILLINOIS.
ble concentration by evaporation of the water in the flask, as
also "bumping," which frequently results in the loss of the
sample, is entirely avoided. At the end of thirty minutes'
digestion, the flask is removed and exactly ten cubic centi-
meters of standard ammonium oxalate solution are added.
When the solution has become perfectly colorless, standard
potassium permangenate solution is run in until the develop-
ment of a faint pink color indicates that the end point is
reached. As the ammonium oxalate solution and the per-
manganate solution are of equivalent strength, we need only
consider the permanganate used in the titration. The strength
of the reagent is such that one cubic centimeter of potassium
permanganate solution used in the titration represents one
part of oxygen consumed in one million parts of water, when
one hundred cubic centimers of the water sample has been
taken for the determination.
In some cases it happens that the ten cubic centimeters
of potassium permanganate solution are insufficient for the
oxidation and the liquid becomes decolorized during the heat-
ing. Another test is then made, in which, instead of ten
cubic centimeters, fifteen or twenty or more, as the case may
be, are employed, the procedure otherwise being the same as
above.
NITROGEN AS FREE OR SALINE AMMONIA.--To five hun-
dred cubic centimeters of the water sample, or in case of river
waters, two hundred and fifty cubic centimeters of the sample
diluted to five hundred cubic centimeters with nitrogen
free distilled water, five cubic centimeters of a twenty per cent
sodium carbonate solution are added and the liquid distilled
from round bottom Jena glass flasks of nine hundred cubic
centimeters capacity. The flasks are supported upon asbestos
rings and heated by direct application of the flame. Connec-
tion with the condenser is made by means of the modified
form of Reitmair and Stutsen safety bulb designed by
Hopkins.
We at first employed condensing tubes of block tin, three-
eights of an inch internal diameter, with cooling surface
twenty inches in length, but we find tubes of aluminum of
the same dimensions far more satisfactory.
The tubes pass through a galvanized iron tank through
METHODS OF ANALYSIS.
29
which a constant current of cold water is kept flowing. Be-
fore each determination the entire apparatus is thoroughly
steamed until free of ammonia. In all ordinary cases of well
waters the distillate is collected in nessler tubes, the boiling
being conducted at such rate that each tube is filled in from
eight to ten minutes. When four tubes are filled it is
assumed that all free ammonia is over,
As most of the river waters and many deep well waters
contain considerable nitrogen as free ammonia, the distillate
from these is collected in flasks of two hundred cubic centi-
meters capacity, the distillation being continued until the
flask is full to the mark, and at such rate that from thirty to
forty minutes elapse between the appearance of the first
drops of distillate and the completion of the distillation of the
two hundred cubic centimeters. The distillates thus caught
are thoroughly mixed, the flasks stoppered and set aside for
nesslerization, a suitable aliquot portion being subsequently
measured off for this purpose.
NITROGEN AS ALBUMINOID AMMONIA.-The determina-
tion of the albuminoid ammonia is made in the usual manner
upon the residue remaining from the determination of free
ammonia. The apparatus and contents having been some-
what cooled, fifty cubic centimeters of the usual alkaline per-
manganate solution are added through a funnel, the flask
immediately connected again with the still, and distillation
proceeded with at the same rate as in the determination of
the free or saline ammonia. The distillate is caught either
in nessler tubes or in flasks of two hundred cubic centimeters
capacity, according as the water contains little or much al-
buminoid matter, and the distillation is considered complete
when two hundred cubic centimeters have come over, though
in many cases ammonia comes over slowly and in small
quantities if the distillation be continued, and even after re-
peated additions of nitrogen free water.
NESSLERIZATION.--In conducting the nesslerization, care
is always taken that the distillates and the standards be of
th same temperature. Commonly those distillates obtained
in the afternoon are allowed to stand in a cool place until the
next morning before proceeding with the determination.
The ammonium chloride solution used for the compari-

sons is of such strength that one cubic centimeter contains
ammonium chloride corresponding to one one-hundredth of
a milligram of nitrogen.
The eighteen standards used in the comparison are made
of the following strengths, . e., the quantities of standard
ammonium chloride solution used are: .05, .1, .2, .4, .6, .8, 1,
cubic centimeter, 1.2, 1.4, 1.6, 1.8, 2, 2.5, 3, 3.5, 4, 4.5, 5,
cubic centimeters.
In nesslerizing, one cubic centimeter of the nessler solu-
tion is added to the contents of each nessler. tube, and the
mixture allowed to stand twenty minutes for the development
of full color. The reagent is always added to the samples
and the standards simultaneously, and the readings are all
taken within one hour of the time when the reagent was added.
The nessler tubes which we use are of colorless glass,
capacity fifty cubic centimeters, length seven and three-
fourths inches to the mark. The bottoms of the tubes are
ground flat and polished.
The comparisons have been greatly facilitated by the
use of a black wooden box or camera which cuts out all side
lights, the tubes being illuminated from the bottom by means
of a mirror reflecting the light from the northern sky, the
cross section of the tubes being brought to the eye by another
mirror placed just above the tubes.
TOTAL Organic NitrogEN.—In surface waters and some
well waters the total organic nitrogen in the original
sample and in the filtered sample is determined by the
Kjeldahl process as follows: Two hundred and fifty cubic
centimeters of the water are diluted with two hundred and
fifty cubic centimeters of nitrogen free distilled water, then
five cubic centimeters of twenty per cent sodium carbonate
solution are added and the mixture distilled as usual for the
removal of all free ammonia, the distillation being pushed
to precisely the same point as that reached in the distilling
over of free ammonia for the determination of free or saline
ammonia and albuminoid ammonia. To the residue in the
flask, ten or twenty cubic centimeters of pure nitrogen free
sulphuric acid are added and the solution heated under the
proper precautions until the water is all expelled and the
organic matter completely destroyed.
METHODS OF ANALYSIS.
31
After cooling the residue, two hundred and fifty cubic
centimeters of ammonia free water are added and then an
excess (usually about fifty cubic centimeters) of strong nitrogen
free sodium hydroxide solution. The flask is immediately
connected with the condenser, the contents mixed by thorough
shaking, and the distillation, which is conducted at first very
slowly, is continued until two hundred cubic centimeters are dis-
tilled over. After thorough mixing, an aliquot portion of
the distillate is employed for the nesslerization in the ordi-
nary manner.
NITROGEN AS NITRATES.--One hundred cubic centimeters
of the water are treated with two cubic centimeters of nitro-
gen free sodium hydroxide solution of thirty-three per cent
strength, then one gram of aluminium in the form of a thin
strip of foil is introduced and the tube and contents placed in
a thermostat which is kept at 30° Centigrade, where it is
allowed to remain over night. The reduction to ammonia is
ordinarily complete when the examinations are continued the
following morning.
In our practice we have found it simplest and most satis-
factory to distill over the ammonia instead of attempting to
nesslerize directly.
The contents of the reduction tube, including such por-
tion of the aluminum foil as remains, are transferred to a
distillation flask, two hundred and fifty cubic centimeters of
nitrogen free water being used to wash out the tube and
dilute the liquid. The distillation and subsequent nessleriz-
ation are conducted precisely as for the determination of free
or saline ammonia. Correction is of course made for saline
ammonia originally contained in the water and that pro-
duced by the reduction of the nitrites present.
When nitrates are present in very small quantity a greater
volume of water is used, but after being made alkaline it
is concentrated to one hundred cubic centimeters before
reducing. If large quantities of nitrates are present, five or
ten cubic centimeters of the sample are used after diluting to
one hundred cubic centimeters with nitrogen free water.
In cases where much free ammonia is contained in the
water sample which is being examined, which include most
32

river waters and many deep well waters, this is removed
before reducing. For this purpose the proper amount of
sodium hydroxide solution is added and the mixture boiled
rapidly in an open vessel to about one-third of its volume, the
final volume being brought up to one hundred cubic centi-
meters again by the addition of nitrogen free water; then the
reduction and subsequent determination is conducted as
above.
NITROGEN AS NITRITES. Fifty cubic centimeters of the
water are placed in a nessler tube, one cubic centimeter of an
acid solution of naphthylamine hydrochloride (8 grams of
naphthylamine, 8 cubic centimeters of strong hydrochloric
acid, and sufficient water to make one liter of solution) and
one cubic centimeter of a saturated solution of sulphanilic
acid in water containing five per cent of strong hydrochloric
acid are added, and the mixture allowed to stand for one hour.
Simultaneously with the addition of the reagents to the
water which is being examined, the same quantities of rea-
gents are added to a series of solutions which contain ac-
curately known quantities of pure sodium nitrite. If a color
appear in the water sample in course of twenty minutes to
one hour after addition of the reagents, it is matched with
the tint produced in some one of the series of standards, and
the quantity of nitrites contained in the original water is
regarded as being the same as that contained in the standard
which produces the same tint. If no color develops in the
course of an hour, the water is considered free from nitrites.
Many of the river waters examined contain so much
nitrites that the color developed in the undiluted sample is too
deep for accurate comparison; in such cases quantities of
from one to ten cubic centimeters are diluted to fifty cubic
centimeters with nitrogen free water before adding the rea-
gents.
Standard solution of sodium nitrite is prepared from pure
silver nitrite by reaction with sodium chloride, and for con-
venience in making up the standards is made in two strengths,
one solution containing in one cubic centimeter the equivalent
of .005 milligram of nitrogen, the other .0005 milligram of
nitrogen,

and decolorized by treatment with aluminium hydroxide and
filtration before testing for nitrites. The comparison of
tints is made in the tubes and the camera described under
Nesslerization.
Dissolved OXYGEN.-For the determination of dissolved
oxygen, we have found the method of Albert Levy most satis-
factory.* The process involves the use of a special pipette
with glass cock at each end. The capacity of the pipettes
which we have used is exactly 107 c. c. The reagents em-
ployed consist of a solution of 100 grams of caustic potash
in a liter of water, a solution of 20 grams of ammonio ferrous
sulphate in a liter of water, a fifty per cent solution of sul-
phuric acid, and a standard solution of potassium permanga-
nate of such strength that one cubic centimeter is exactly
equivalent to one-tenth of a milligram of oxygen.
The method of procedure is as follows: The pipettes
are filled with the water either by immersing in the stream
itself or by use of a rubber syringe. Then two cubic centi-
meters of the caustic alkali solution is put into the funnel at
the top, and, by careful manipulation of the two cocks, is
allowed to enter and mix with the water without admitting air.
The funnel is then rinsed out and five cubic centimeters of the
ammonio ferrous sulphate solution introduced into the funnel
and then into the pipette by the same manipulation as before.
The water run out the pipette at the bottom as the reagents
are admitted at the top is caught in the beaker in which the
subsequent titration with permanganate is to be effected and
which already contains two cubic centimeters of 5 per cent
sulphuric acid.
It is assumed that the alkali and the iron solutions in enter-
ing the pipette displace their own volume of water, and with
careful manipulation this undoubtedly is essentially effected,
so that we may assume that within the pipette there remain
one hundred cubic centimeters of the original water with
seven cubic centimeters of the reagents.
The mixing of the liquids within the pipette is effected
by shaking the pipette with an eccentric rotatory motion. In
the course of a few minutes the action is completed, and from
the color of the precipitate one may gather an idea as to the
*This method is as described in the Annuaire de L'Observatoire de Mont-Souris
for 1883 and subsequent years.

relative amount of oxygen contained in the solution. That
is, if the water is about saturated, the precipitate is apt to
show a somewhat brownish color due to the ferric hydroxide,
while if the quantity of oxygen is very small the precipitate
is likely to be black, showing the preponderence of the fer-
rous hydroxide in the precipitate.
After a few minutes, when the action is thought to be
complete, five cubic centimeters of sulphuric acid are intro-
duced into the funnel, and the cock between the funnel and the
pipette being opened, the sulphuric acid, by reason of its
greater gravity, passes from the funnel down into the interior,
and mixing with the liquid dissolves the hydroxides of iron
and renders the entire liquid acid.
When this reaction is complete, as shown by the clearing-
up of the solution, the contents of the pipette and the rinsing
water are run into the beaker, and the excess of ferrous salt
determined by titration with the standard permanganate so-
lution. A blank is run upon one hundred and seven cubic
centimeters of the original water for every determination that
is made, this being easily done while the reactions are taking
place within the pipette.
In running the blank, one hundred and seven cubic centi-
meters of the water are measured into a beaker, then seven
cubic centimeters of the sulphuric acid are added, and the
liquid mixed; after this the caustic potash, two cubic centi-
meters is added, and finally, precisely five cubic centimeters of
the ferrous sulphate solution; then the titration is effected as
in the actual determination. The difference between the two
readings, i. e., that of the blank and that of the direct deter-
mination, represents the quantity of dissolved oxygen in one
hundred cubic centimeters of the water.
We have found the method of Levy more convenient than
the Winkler method. Its advantages appear to us to be
mainly due to the fact that the blank to accompany each de-
termination is so easily made; whereas with the Winkler
method, the determination of the blank, which, with the
river waters concerned in these investigations is generally
necessary for every sample examined, entails so much labor
as to limit the applicability of the method.
As it has not been practicable for us to make all of the
REPORTS OF ANALYSES.
35
oxygen determinations upon the spot, we have had a great
many special samples of water shipped from the river to the
laboratory. The determinations of the oxygen in these are,
in most instances, made within twenty-four hours of the time
of collection, but in that length of time the dissolved oxygen
is found in most cases to diminish considerably in amount.
The waters of the Illinois river and its tributaries and
those of the Mississippi contain a great deal of organic matter
which is easily susceptible to the influence of dissolved oxygen.
We have found, however, that it is perfectly practicable to
treat the water samples with a little mercuric chloride and
thus prevent such reactions as result in the disappearance
and consequent diminution of the dissolved oxygen; so that it
has been practicable for us in the laboratory to make the
comparison of the original quantity and also of the staying
qualities of the dissolved oxygen in the water.
With a set of samples treated with a few drops of satu-
rated solution of mercuric chloride, we get results which are
essentially the same as those shown by determinations on the
spot, while with the other set of samples which have been
shipped in the original condition, i. e., merely in bottles which
are entirely filled but which have not been treated with
mercuric chloride, it is found that the dissolved oxygen is
considerably less in amount. The difference between the two
is a rough indication of the condition of the water with re-
spect to content of dissolved oxygen and content of such im-
purities as easily cause the disappearance of dissolved oxygen.
Our comparisons of the Winkler method *with the Levy
method show that the latter method gives somewhat higher
results, but the differences are ordinarily very slight, and for
comparative results the Levy method is so superior in economy
of time and labor that of late we have used it almost ex-
clusively.
REPORTS OF THE CHEMICAL EXAMINATIONS.
Many citizens of the State have taken advantage of the
opportunity offered by the University, to obtain chemical
analyses of their respective water supplies and in consequence
we have made examinations of many samples of water derived

from various individual household sources of supply, the num-
ber of such waters averaging about five hundred each year.
The results of all such analyses are reported immediately
to the sender of the sample and when sufficient information
concerning the source of the water is at band, an interpreta-
tion of the results and an opinion regarding the wholesome-
ness of the water is furnished, together with whatever rec-
ommendations seem requisite or desirable. The blank form

corded in the report, is equivalent to one ten-thousandth of
one per cent., or is equivalent to .058335 grain per United
States gallon of 231 cubic inches.
In arriving at the conclusions set forth in the report the
following is the basis of interpretation of the analytical data;
First, the substances referred to and upon which the re-
port is made are not considered to be in themselves harmful
in the quantities which are found in potable waters, but they
are significant of the condition of the water for reasons
which may be briefly stated as follows:
"TOTAL RESIDUE BY EVAPORATION" Comprises the solid
matters left upon evaporating the water and drying the resi-
due at 180 degrees centigrade. It includes both inorganic
and organic substances. The inorganic constituents are salts,
and comprise mainly compounds of lime, magnesia, soda,
potash, iron and alumina, with chlorine, carbonic, sulphuric,
nitric and silicic acids. Unless the quantity of mineral matter
is excessively high, the determination is not particularly sig-
nificant, and ordinarily for sanitary purposes the individual
constituents are not separately determined.
"FIXED RESIDUE" (mineral matter) is that portion of
the total solids which is inorganic, and is neither burned
away nor otherwise decomposed by application of heat,
"VOLATILE MATTER" (loss on ignition) comprises the
loss in weight which the "total residue by evaporation" suf-
fers on being heated to redness. It includes the organic mat-
ters, which burn away, and such constituents of the mineral
matters as are volatile or are decomposed by heat into volatile
products. This determination is of special significance only
in so far as the manifestation of a change in color, the de-
velopment of odors, or the evolution of fumes, or the absence
of any such change, may indicate the nature of the con-
stituents of the water.
"CHLORINE IN CHLORIDES" refers to the quantity of
38
WATER SUPPLIES OF ILLINOIS.
chlorine contained in the water in combination with the basic
elements. It is a considerable constituent of common salt.
Most animal matters contain more or less chlorides, and
chlorides are constant and considerable constituents of sewage
or drainage from refuse animal matters.
The presence of chlorine in water in amounts exceeding
the normal quantity generally indicates that the water has
been polluted by animal matters, but is not conclusive evi-
dence thereof, and it must be remembered that the waters of
many deep wells contain large quantities of chlorides de-
rived from subterranean deposits of salt.
"OXYGEN CONSUMED" refers to the quantity of oxygen
required to oxidize the organic matters present in the water.
In general, a considerable quantity of oxygen required for
this purpose represents a considerable quantity of organic
matter in the water, and vice versa, a small quantity of oxy-
gen consumed indicates comparative freedom from organic
matters. However, many of the organic matters which may
be contained in water are not readily affected by the oxidiz-
ing agent and in no case does the quantity of oxygen con-
sumed bear a definite and direct ratio to the total quantity of
organic matter contained.
THE ORGANIC MATTERS. -No practicable means exists
for the accurate determination of the quantity and the char-
acter of the various individual organic substances contained
in water.
These substances include living organisms, both vegeta-
ble and animal; products of organic life as fæcal matters, etc.,
and products of the decomposition of organic matters.
Nitrogen is an essential constituent of all living things;
it is to the nitrogenous organic matters that the greatest
sanitary importance attaches; and as accurate methods fo
the determination of nitrogen in the four forms in which it
may exist in water are available, the study of the organic
matters is usually limited to the investigation of the nature
and the quantity of the nitrogenous substances.
"NITROGEN AS ALBUMINOID AMMONIA" represents the
nitrogen contained in the various organic substances which
exist in the water in the undecomposed state. These
include the products of organic life, as albuminous sub-
INTERPRETATION OF RESULTS.
39
stances, tissues, urea, fæcal matters, etc., etc., substances
which serve as nutrients upon which germs thrive and mul-
tiply; and also living organisms themselves, both vegetable
and animal, including bacteria. The presence of much
nitrogen as albuminoid ammonia usually suggests pollution
with sewage or drainage from refuse animal matters.
"NITROGEN AS FREE AMMONIA," So-called, represents
ammonia contained in the water in either the free or saline
condition, and which usually proceeds from the natural de-
composition of nitrogenous organic matters in the first
stages of oxidization. Its quantity is ordinarily indicative
of the amount of organic matter which is contained in the
water, in a partially decomposed state. It is a characteristic
and a considerable constitutuent of sewage.
Both free ammonia and albuminoid matters in water, in
undergoing decomposition are oxidized, the final product be-
ing nitric acid, which unites with the basic mineral matters
present and consequently appears as nitrates.
"NITROGEN AS NITRITES."--Nitrous acid, or nitrites,
constitutes the second intermediate stage in the oxidation of
nitrogenous organic substances into inorganic products. The
presence of any considerable quantity of nitrite in the water
shows generally that decompositions due to the vital processes
of living organisms are under way, and the quantity of
nitrite indicates in some degree the character and the amount
of organized life present in the water.
"NITROGEN AS NITRATES."-Nitrates are the final pro-
ducts of oxidation of the nitrogenous matters; their presence
in considerable quantity indicates that at least correspond-
ingly considerable quantities of organic matters have been
previously contained.
The significance of all four of these forms of nitrogen is
not complete evidence unless considered in conjunction with
the other constituents, and in reference to the nature of the
source of the water.
Vegetable organic matter is comparatively harmless.
The presence of animal matters on the other hand usually
subjects the water to grave suspicion, since the danger at-
tending the presence of organic matters in water arises.
chiefly from the fact that accompanying matters of animal

origin there will be, in case of disease, also disease germs
themselves.
STANDARDS OF PURITY.
Because of differences due to the nature of the strata from
which waters are drawn or with which they have been in
contact, the topography of the district, and the general en-
vironment of the sources, no fixed standards of purity where-
by to judge the condition of any and all potable waters can
be justly established, yet for purposes of comparison, and for
the information and convenience of those to whom our re-
ports are sent, the following limits have been provisionally
adopted as a reasonable basis for reaching conclusions re-
garding the wholesomeness of the waters of ordinary shallow
wells in the State of Illinois:

and no offensive odor should be developed.

The formation of a reasonable and just opinion regarding
the wholesomeness of a water requires that all of the data of
the analysis be taken into consideration, together with
the history of the water; the nature of the source; the charac-
ter of the soil and earth or rock strata; and the surroundings.
This is a task for the expert, and the purpose of this sheet

the evidence and the line of argument, as shall aid him to an

and advice which is given him concerning the water supply

THE GEOLOGY OF ILLINOIS AS RELATED TO
ITS WATER SUPPLY,
BY
CHARLES W. ROLFE, M. S., PROFESSOR OF GEOLOGY,
UNIVERSITY OF ILLINOIS.
INTRODUCTION.
As it would be impossible in the space assigned me to en-
ter into a detailed description of the geological forces which
have made our state what it is, and as many of my readers
have not been able to take a course in modern geology, I
have thought that it might be helpful to place here, in a few
concise sentences, some ideas, now generally accepted by
leaders in the science, which have a direct bearing on the
history of our state.
GEOLOGICAL CONCEPTS.
1. All Illinois rocks were formed when this part of the
earth's surface was beneath the sea, of materials carried in
suspension or solution by streams from some dry land area.
2. Sediments deposited on the bottoms of shallow seas
gradually sink into the earth as a weight would sink into a
ball of plastic clay; hence layers of great thickness may be
formed, all of whose ingredients were deposited in shallow
water.
•
3. When coast lines remain stationary for long periods,
great quantities of sediment are deposited in a comparatively
narrow belt along the shore, but little being carried into deep
42
WATER SUPPLIES OF ILLINOIS.
water. In this case the older layers will gradually settle in
the center as newer ones are laid down, and in the end a
solid half cylinder composed of concentric layers will be
formed. (See trough spoken of below.)
4. The earth is solid from center to circumference, its
interior is very hot, and the whole earth is continually grow-
ing smaller, shrinking from loss of heat. As the outside
layers receive heat from the sun, and do not shrink as fast as
the interior, they must buckle or be thrown into folds and
depressions. These folds and depressions are sometimes
hundreds of miles in breadth, sometimes narrow like the Ozark
ridge in southern Illinois. When folds are formed in a shal-
low sea the bottom may thus be raised above the surface of
the water, and again areas of small elevation may be depressed
below sea level.
5. An area which has recently risen from the ocean will
have an approximately smooth surface. On such an area
a system of water courses will soon be formed. The indivi-
dual streams will increase in length by pushing their sources
further inland, and will throw out branches until the whole
surface is covered by a net work. (See Glacial map, southern
part.) Rapidly flowing streams erode or cut their beds and
gradually sink into trenches, often hundreds of feet deep, of
their own construction. Examples: Illinois River, Galena
River.
6. All stream beds are trenches, All river bluffs are the
sides or walls of such trenches. Sometimes the bluff forms
an abrupt bank, but it is often a more or less gradual slope,
rising gently to the general level. The top of the bluff is on
a level with the surrounding country. As the bed of a stream
approaches the level of any flat surface over which it must
flow, it stops cutting its bed, begins to wind, and by under-
cutting the banks widens its trench and develops a flood
plain. Rain, frost, and other influences aid the widening.
A net work of streams, each widening its trench, will in
time reduce the ridge to a series of hills (buttes) separated by
broad valleys, and ultimately carry even these away, forming a
peneplain. In this way three hundred or more feet of rock have
been removed from the entire northwestern part of the state,
leaving only a few mounds, Pilot Knob, Scales Mound, Charles
GEOLOGICAL CONCEPTS.
43
Mound, etc., etc. A similar action has removed hundreds of
feet from the Ozark Ridge leaving Bald Knob, Williams Hill,
etc. Wherever a hill occurs which is made up of rocks in
horizontal layers, we may be certain that its crest represents
a former level of the country. Nearly all irregularities in
the surface of Illinois are due to stream action.
7. Underground water moves in the direction of least
resistance; sloping beds of sand, gravel, sandstone or other
porous material when overlaid by denser layers become water
ways.
When an opening is made from the surface through
the impervious to the porous layer, the water will rise in the
pipe until its weight equals the resistance which it
encounters in continuing its course down the slope. When
the resistance to forward motion is absolute, the water will
rise to the level at which the porous layer comes to the sur-
face. If the resistance is only partial the water will not rise.
so high. If the relative elevation of the source and the re-
sistance in front are sufficient, a flowing or artesian well will
be formed.
8. Pump wells differ from artesian wells only in the
height to which the water is raised. Springs in which the
water rises from the bottom are natural artesian wells,
9. Coal beds are usually peat bogs solidified by pressure.
The trunks of large trees which grew abundantly about the
margins of these bogs usually decayed while lying on the
surface and so but seldom helped to form the coal.
10. Fields of ice and snow accumulate whenever the an-
nual heat of the sun is not sufficient to melt the annual snow
fall. The thickness of the ice depends only upon the annual
surplus and the number of years it has been accumulating.
Ice is plastic or behaves as though it were. When masses of
ice become very thick their weight causes the lower layers to
flow outward, or spread, and this they will continue to do un-
til their edge reaches latitudes where the annual heat can
melt the annual supply. Such spreading masses are called
glaciers. Glaciers formed in British America have several
times spread southward over the northern United States.
Three or four of these have covered portions of Illinois.
11. Glaciers pick up fragments, varying from dust parti-
cles to pieces tons in weight, of every kind of rock over which
44
WATER SUPPLIES OF ILLINOIS.
they pass, and when they melt deposit all in a heterogeneous
mass.
12. Long ridges which are made up of clay (rock flour)
and fragments of various kinds of rocks, as well as isolated
mounds or ridges of gravel like those in northeastern Illinois,
are usually moraines made by the last (Wisconsin) glacier.
(See Glacial map.)
13. Single mounds, clusters of mounds or short ridges
like those occurring in Fayette, Bond, St. Clair, and Sangamon
counties, when made up of like materials, are fragments of
moraines of the first (Illinois) glacier broken by stream ac-
tion. (See Glacial map.)
14. Thick deposits of clay carrying patches or layers of
sand and gravel and containing stones of many different
kinds may be considered as belonging to the ground moraine.
Such deposits often aggregate two hundred and fifty or more
feet in thickness, as at Bloomington, Champaign and Gil-
man.
15. In localities underlaid by a heavy ground moraine the
enclosed patches of sand and gravel are the main sources of
water supply for both artesian and pump wells.
AN OUTLINE OF THE GEOLOGY OF ILLINOIS WITH KEference
TO ITS WATER SUPPLY.
Geologists believe that at the close of Archean time
the portion of the earth's surface covered by the state of Illi
nois was, and had been for a very long period, part of a dry
land area; that its surface was made up of crystalline rocks,
and that this surface was everywhere cut and seamed by the
large, deep valleys and minor water courses of a well estab-
lished drainage system. (See Introduction 1-6.)
The opening of Paleozoic time found this land mass slow-
ly sinking. By or before the middle of the Cambrian era
it was completely covered by the ocean (Introduction 4),
and the sediments derived from other land masses were
being deposited upon it, covering the whole area with
mass of alternating layers (sand stones, shales, and lime-
stones), known as the Potsdam formation, whose average
thickness in this state is unknown, but can hardly be less

than fifteen hundred or two thousand feet. (Introduction 1,
This formation does not appear at the surface within the
area of our state, being completely covered by subsequent de-
posits. Its sandstone layers constitute our deepest sources of
artesian water. (Introduction 7, 8.)
The submergence of the entire area by the waters of a
very shallow sea continued during the whole of the Lower and
Upper Silurian ages, with the exception of a brief emergence
at the close of the Calciferous epoch. (Introduction 4.) There
is not sufficient evidence from deep borings to enable us to de-
cide whether this emergence affected the entire area of the
state, but we know that it did affect the northern portion and
continued long enough to permit the establishment of a well
developed drainage system, the presence of the divides and
valleys of which will account for the widely varying thick-
ness of the following (St. Peters) formation within small
areas. (Introduction 5, 6.)
During the above mentioned submergence, there were laid
down over the entire area of the state (1) The Lower Mag-
nesian Limestone (Calciferous), a heavy bedded deposit of
limestone, occasionally passing into shales, one hundred or
more feet in thickness. This formation underlies the whole
state but its only outcrop is in the bluff of the Illinois River
between Utica and La Salle, where it is used for the manu-
facture of hydraulic cement.
(2) The St. Peters Sandstone (Chazy), a loosely aggre-
gated bed of unusually pure quartz sand. This formation
varies from fifty to three hundred feet in thickness, and is the
main reliance for artesian water in the northern part of the
state. As the sand was laid down on tidal flats in large part
it sometimes encloses deposits of various salts laid down by
the evaporation of pools of sea water. These salts are re-dis-
solved by undèrground water in its passage through the rock,
and for this reason the water is oceasionally so charged with
mineral matters as to be unfit for use. The St. Peters is us-
ually a very loosely aggregated sandstone, and hence forms
an excellent water-way. In certain places, however, it occurs
as a compact rock through which water cannot flow rapidly.
At such points wells usually fail to give an adequate supply.

between Ottawa and La Salle; in the Rock River valley near
Oregon; and near the southern point of Calhoun county at
Cap-au-gres. The wide variations in the thickness of this
formation are due to the fact that it was laid down on an irreg-
ular surface produced by erosion during the emergence
spoken of above. The places where the formation is thick-
est represent old river valleys, while the thinner portions lie
on the divides. (Introduction 5, 6.) The Lower Magnesian and
St. Peters together constitute the Canadian group. (See
Geological map.)
(3) The Trenton, a massive bed of limestone divided in-
to three portions known as the Buff, Blue, and Galena lime-
stones with an aggregate thickness of two to four hundred feet.
It forms the surface rock over most of the counties Jo Daviess,
Stephenson, Winnebago, Boone, Ogle, Lee, Carroll, and con-
siderable portions of Whiteside, Bureau and La Salle, but un-
derlies the whole State, outcropping also in small areas in
Calhoun, Monroe and Alexander counties, where it is brought
up by faults. (See Geological map.) This formation encloses
the lead deposits of northwestern Illinois, and carries oil
and gas in Ohio and Indiana. While there are abundant evi-
dences of the presence of oil and gas in the Trenton of Illinois,
the geological structure of our State makes the presence of
large deposits connected with this formation very improbable.
(4) The Cincinnati (Hudson River,) a shaly limestone or
coarse shale with occasional layers of porous sandstone, from
fifty to two hundred feet in thickness, which covers the sur-
face in portions of Boone, DeKalb, Ogle, Lee, Whiteside,
Henry, Bureau, Kendall, Grundy, Will, Kankakee, and Ford
counties, with small outcrops in Pike, Calhoun, Union, and
Alexander counties. In the village of Montgomery just south
of Aurora, Kane county, the sandy layers of this formation
supply the artesian water which, under the names of Aurora
Magnesia and Aurora Lithia water, is so largely sold in
Chicago. The supply is probably derived from rain which
falls on the outcrop in DeKalb county. (Introduction 7, 8.)
The Cincinnati originally covered the same area in the north-
western part of the state as is outlined for the Niagara below,
but like it has been removed by erosion. It underlies the
remainder of the state. (See Geological map.)
OUTLINE OF ILLINOIS GEOLOGY.
47
(5) The Niagara, a heavy bedded limestone, valuable
for building stone, with quarries at Batavia, Aurora, Naper-
ville, Lemont, Joliet, Kankakee, and Grafton, formerly covered
the entire northern portion of the state, but has been largely
eroded over most of the area indicated above as having rocks
of the Trenton and Cincinnati series at the surface, leaving
only scattered masses in the form of mounds or elevated
plateaus to tell of its former presence. (Introduction 5.) It
now occurs as a surface rock only in the northeastern portion
of the state, Lake, McHenry, Cook, Dupage, Kane, and
most of Will, Kankakee, Iroquois, and De Kalb counties, with
small areas in Calhoun, Jersey, and Alexander (see Geologi-
cal map,) except as noted above.
At the close of the Upper Silurian era the whole north-
ern part of the State, as far south as the Illinois River and
extending on the east to the south line of Ford county, was
elevated into dry land, and with the exception of a narrow
margin at the south has not since been covered by the sea.
This area now lies on the eastern slope of a low anticline, and
the rocks dip toward the east at the rate of perhaps three or
four feet to the mile. (Introduction 4.)
Shortly after, or perhaps contemporaneous with this up-
lift, a great trough (geosyncline) began to form, with its axis
lying in a line beginning near La Salle, and running south-
east, with slight curvature to the west, to a point near the
southeastern corner of Wabash county, where it leaves the
state. (Introduction 2, 3.) During the formation of this
trough, the deposit of sediment kept its surface approximate-
ly level. Hence, the Subcarboniferous and Coal Measure
strata (we do not know about the Devonian) increase in
thickness rapidly as they approach its axis, attaining a thick-
ness of more than eighteen hundred feet at Champaign, and
more than three thousand feet at Tuscola and Paris.
Considering now that portion of the state limited rough-
ly by the parallels of La Salle and Carbondale, we have the
rocks heretofore described, lying in the form of a great trough
or a half cylinder. The various formations appear at the sur-
face near the east and west boundaries of the state, and de-
scend to a depth of over three thousand feet near the axial line
of the trough.
48
WATER SUPPLIES OF ILLINOIS.
Within this area, wherever prospecting has been carried
deep enough, the Devonian formation, which consists of a
mass of dark or black shale, with or without a correspond-
ing layer of exceedingly pure limestone, and which attains a
thickness of thirty to one hundred feet, has been found lying
directly on the Niagara. This formation outcrops near Rock
Island, at Cap-au-gres in Calhoun county, and in Alexander
county, but the outcrops cover only a small area in each case.
It forms the floor on which the coal measures rest along the
northern boundary of the area. It is not known whether this
formation increases in thickness as we approach the axis of the
trough, because the deepest borings in this part of the state'
have not reached its surface. (See geological map.)
Immediately above the Devonian lies the massive Subcar-
boniferous formation, composed of sandstones and shales, with
more or less limestone below; thick beds principally of lime-
stone which become shaly as we approach the eastern border
of the state, in the center; and alternations of limestone and
sandstone above. This formation outcrops along the western
boundary of the state from Mercer county in the north to
Jackson county in the south, attaining an average thickness
of perhaps five or six hundred feet,-about one hundred in the
north and perhaps twelve hundred or more in the south. Its
thickness increases toward the east, reaching more than two
thousand feet near the axis of the geosyncline, and its sub-
divisions shingle out toward the northwest. As the Subcar-
boniferous outcrops in the Ozark Ridge, and is thus carried
above the general level, its sandy or porous layers, in connec-
tion with the conglomerate which lies at the base of the Coal
Measures, form the main source of artesian water in the south-
ern part of the state. (Introduction 7, 8.)
At the close of the Subcarboniferous the area under con-
sideration was elevated into a series of marshy plains inter-
spersed with islands--like highlands and ridges, and oscil-
lated between this condition and one of slight submergence
for a very long period (Introduction 4) during which thick
deposits of shale and sandstone with occasional and local
beds of limestone were accumulated. Intercalated in these
shales and sandstones are many lens-shaped or flattened
cylindric deposits of coal, accumulated in basins of elon-
OUTLINE OF ILLINOIS GEOLOGY.
49
In these basins
gated swampy areas (Introduction 9.)
mosses and other water-loving plants grew in abundance
and formed thick beds of peat, while all around the margin of
the marshes grew club mosses, scouring rushes, and ferns, of
the size of forest trees, and on the higher and drier areas
were forests of conifers. The coal was made principally
from the peat. Club mosses, scouring rushes, and ferns con-
tributed leaves and small branches with an occasional tree
trunk, while the conifers furnished only leaves and fruits.
Whatever materials fell upon, and were incorporated into the
vegetable debris of the marshes, helped to form coal, while
that which fell upon higher ground decayed as do the ma-
terials of our forest today. It is for this reason that coal was
formed only in the marshy areas of that period, and for this
reason also that coal from different parts of the same basin
varies so widely in the amount of ash which it carries, be-
cause the wash of the higher lands would be caught and
retained by the mosses near the shore of the marshes and so
would rarely reach the center, where the deposits of purest
coal are usually found. Irregularities in the bottom of the
old marsh are marked by "hog backs" which rise from the
bottom and partially or entirely cut out the coal bed, while
the beds of streams which crossed the marsh are indicated by
V's which descend from the roof. Each submergence covered
the deposits already formed, and each emergence formed new
basins and marshes in which other deposits accumulated.
Professor Worthen tried to arrange these basins in six-
teen identifiable horizons, each marking a period of general
submergence. He numbered the horizons 1-16, beginning at
the bottom. This attempted grouping probably has little
value, for it is all but certain that this area was in continual
movement, sometimes upward, sometimes downward, as are
portions of the western coast of Italy today, and it is practi-
cally impossible that the whole area should have been sub-
merged at any one time, or that all parts should have been
marshy at the same time. The coal measure deposits attain
a thickness of twelve hundred or more feet along the axial
line spoken of above (Introduction 2, 3,) but thin rapidily
toward the east and west, disappearing entirely, except in one
or two points, at some distance east of the western margin of
50

the state. Near the close of the Coal Measures this area be-
came dry land and has not since been invaded by the sea.
During the early part of the Coal Measures an east-west
ridge, formed by the upward arching of the Subcarboniferous
and the Basal Conglomerate of the Coal Measures, began
to rise along the southern margin of this area. (Introduction
4.) (See Geological map.) This ridge has suffered large erosion
• during the intervening period, but still has peaks which reach
an altitude of more than one thousand feet above tide (Wil-
liams Hill, Pope county, 1046 feet; Bald Knob, Union county,
985 feet) or five to six hundred feet above the surrounding
land. (Introduction 5, 6.) It probably forms a part of the
Ozark uplift, and hence is called the Ozark Ridge or Ozark
Mountains.
During the whole of Mesozoic, and part at least of
Tertiary times, the Atlantic sent a broad, but gradually nar-
rowing, gulf northward to the southern slope of the Ozark
Ridge, and rocks were laid down of whose thickness and
character we know very little, as the area contains very few
natural sections and not many borings have been put down.
All the rocks described above were deposited in seas of
no great depth, and often during this deposition portions of
their surface were above water. At such times shallow pools
would be left without connection with the ocean. The water
would evaporate and whatever salts it contained would be
deposited with the other rock material. When a well is sunk
the water in order to reach it must often pass through these
salt beds. The salts are dissolved and the water tainted.
The word salt here does not refer to common salt alone, but
to all substances which are dissolved in sea water.
The shallow waters teemed with organisms whose bodies
after death were buried in the accumulating rock material.
The decomposing flesh gave off hydrogen sulphide as a gas,
which bubbling up through the water, took possession of
such dissolved bases as it came in contact with, and deposited
them as sulphides among the rock fragments. Most rocks con-
tain more or less sulphides (iron pyrites, galena, blende, etc.)
After the rocks have been elevated into dry land, rock water
often carries acids strong enough to displace the hydrogen
sulphide and it flows away in solution, to appear again as
OUTLINE OF ILLINOIS GEOLOGY.
51
sulphur water in our springs and wells. Oxygen also con-
verts sulphides into sulphates which dissolve in the water.
In a similar manner rock water may be impregnated with any
one of many mineral substances found in the rocks.
Underground water often flows more rapidly through
stratified rocks than through loose material (Introduction 7,)
because the numerous joints offer relatively small resistance
to movement of the greater portion, while the pores of the
rocks themselves permit a slow movement of the rest. It is
or this reason that where rock strata reach or come near to
the surface, contaminating influences are much more likely to
be widely spread, and to injuriously effect the drinking water
of the region, than is the case where the surface material has
not been solidified into rock.
Subsequent to the elevation of the entire area of the
State into dry land, and after the lapse of a very long period
during which surface streams became numerous and ran in
deep channels which they had formed for themselves, estab-
lishing a perfect drainage system and cutting the surface up
into a series of ridges, watersheds, and stream valleys (In-
troduction 5, 6,) an ice sheet, called the Illinoian Ice Sheet,
appeared in the north and slowly pushed its way southward
to the latitude of the Ozark Ridge. (Introduction 10.) This
glacial advance was not accomplished by a steady southward
movement, but rather by a series of oscillations backward and
forward, according as the rate of melting exceeded or fell
short of the rate of advance. The ice sheet carried great
quantities of rock flour, bowlders and other materials which
it had picked up as it moved southward from Ontario and
Manitoba (Introduction 11.) and whether this ice front was
advancing or receding, it was continually depositing this
debris as it melted, forming a ground moraine, thick in the
valleys thinner on the old divides.
In this way the glacier pushed forward, depositing a
thick layer of sediment, until its southern limit, described
above, was reached when it began to retreat, The retreat
was marked by the same oscillations of movement as the ad-
vance. Sometimes these oscillations were short, and the
backward and forward movements depositing layer upon layer
of debris, resulted in the building up of a ridge of greater or

less altitude (occasionally one hundred feet or more above the
surrounding country) called a terminal moraine. (See Glacial
map.)
Again the retreats would be long, laying bare broad areas.
called ground moraines, whose surface sloped from the terminal
moraine to the ice front. The surface of glacial deposits is
always uneven; hence this area would soon be covered with
series of lakes or ponds connected by streams which begin on
or near the terminal moraine and extend downward toward
the ice front. In some parts of these, rapidly moving currents
would quickly pick up and carry away the loose material over
which they flowed, until coming into the broader and more
sluggish lake waters, they would lose velocity and be com-
pelled to deposit the heavier particles of their load, building up
in this way beds of sand and gravel often many teet in thick-
In other parts a slowly moving stream unable to carry
the heavier particles which formed its bed and banks would
pick up the finer rock flour and bear it away leaving a shallow
layer of sand and gravel upon its bed. Thus connected series
of porous deposits would be formed reaching from the ice front
upward to the crest of the moraine.
ness.
The next advance of the glacier would cover these with a
layer of compact material, and they would thenceforth be
pockets of pervious material enclosed in more impervious
drift. A series of long oscillations, each retreat depositing a
layer of drift material, upon which was developed series of
strings and patches of gravel, which in turn were covered
with a layer of drift by the next advance, would form a thick
ground moraine, having pockets of water-bearing gravels
scattered here and there at many horizons.
Driven or bored wells drawing their supply from these
pockets of sand or gravel are subject to contamination only
from sources of pollution situated on or near the outcrop—a
limited area on the flank of the moraine. If the distance
from this moraine be considerable, any organic matter enter-
ing at the outcrop will probably be oxidized and rendered
harmless before reaching the well. Dug wells, on the con-
trary, usually pass through thin layers of sand and gravel
before reaching one sufficiently large to furnish the needed
supply. The outcrops of these thin bands are often not far
OUTLINE OF ILLINOIS GEOLOGY.
53
distant from the well, and any source of pollution at or near
these outcrops is liable to seriously affect the character of the
water.
The fact that the water of a given well is unfit for use is
not presumptive evidence that other wells in that immediate
vicinity are bad. They may draw their supply from other
pockets, and the outcrops of these different pockets are almost
certain to be so widely separated that they are not subject to
the same sources of contamination.
There is no relation between the depth of wells and the
purity of their water, except that the gravel of the deeper
well usually has the more distant outcrop, and hence if equal
sources of pollution exist at each outcrop, the deeper well
would be more likely to have its contaminating influences
oxidized, but very shallow wells often draw their supply from
pockets whose outcrops are so situated that they are not lia-
ble to contamination and so supply the purest of water,
while the reverse is occasionally true of deep wells. The
fact that the ground moraine contains gravel beds at different
horizons explains why wells in the same neighborhood often
differ so widely in depth.
The Illinoian Ice Sheet retreated in the manner indicated,
leaving terminal moraines at its various resting places, and
between them a ground moraine which averages perhaps fifty
feet in thickness (this deposit was, of course, thicker in the
preglacial valleys and thinner on the divides) until it had
passed beyond the limits of the United States, and possibly
disappeared from British America also. (See Glacial map,
Illinoian Moraines.
Then there seems to have followed a long interval with
climatic conditions not unlike the present, during which (1)
numerous water courses were formed, excavating a network
of deep channels for themselves (Introduction 5, 6, and often
cutting through the moraines and dividing them into a series
of short ridges, which in many cases have since been cut up
into clusters of mounds, like those near Hillsboro, Montgom-
ery county; (2) the blue glacial clays were leached to the
depth of several feet, losing much of their lime, becoming
porous and of a yellow color; (3) soils were formed-black
soils in the swamps and lake beds, lighter ones on the higher

lands, and (4) the surface was covered with vegetation, much
of it with forests.
In many of the lakes where sufficient current existed to
carry away the finer material, beds of gravel many feet in
thickness accumulated, some of which covered square miles.
in area. Other beds of gravel, forming long lines or ridges
often of great thickness, were laid down by the outwash from
beneath the glacier. All these and other masses of sand and
gravel, accumulated in a somewhat similar manner, form
excellent storage for water when covered by subsequent gla-
cial deposits. Many cities of central Illinois, some of which
have a population of fifteen thousand or more, draw their
water supply from such beds. In well sections in the north-
eastern part of the state this horizon may usually be recog-
nized by the occurrence of one or more of the following phe-
nomena: beds of leached yellow clay, large nearly horizontal
beds of gravel, deposits of natural gas, or black soil.
During this interglacial epoch, and before the changes
enumerated above were fully perfected, a second ice sheet, the
Iowan, appeared in the northwest, and advanced over Ste-
phenson, Ogle, Lee, and some portions at least of adjoining
counties. Its exact boundaries have not been determined. (In-
troduction 10, 11.) On its disappearance it left a sheet com-
posed of terminal and ground moraines similar in all respects
to those of the Illinoian drift. The junction of the Illinoian
and Iowan drift is marked by phenomena similar to those in-
dicated above.
(Leverett.)
After the retreat of the Iowan sheet there was another
long interval during which changes in its surface similar to
those described under the Illinoian sheet were produced.
Then, a third ice sheet, the Wisconsin, advanced (Introduction
10, 11,) this time following the valley of Lake Michigan, but
spreading broadly to the west so that it covered about one-
half of the width of the state at its northern boundary. This
sheet advanced southward until it extended over all the por-
tion lying north and east of a line running roughly through
Belvidere, Amboy, Peoria, Clinton, Decatur, Shelbyville, and
Charleston. This line is marked by a strong terminal mo-
raine lying near these towns. (See Glacial map, Wisconsin
Moraines.) During its retreat it deposited a series of ground

and terminal moraines whose average thickness is perhaps.
fifty feet, but as the sheet was deposited on a surface on which
a nearly complete drainage system had been established (In-
troduction 5, 6,) its depth varies greatly, often reaching one
hundred and fifty or more feet in the interglacial valleys and
being reduced to a very few feet on the interglacial divides.
The junction between the Illinoian and Wisconsin drift is
usually strongly marked by the occurrence of such phenomena
as were described above. (Page 54.) A similar but less plainly
marked parting exists between the Iowan and the Wisconsin.
(Leverett,)
The retreat of the Wisconsin sheet was so recent that its
terminal moraines still generally retain their ridge-like char-
acter. (See Wisconsin Moraines, Glacial map.) The drainage
system is very incomplete. The main streams are not fully
developed and have few branches. The country has harály
emerged from the swampy condition induced by imperfect
drainage. The black soil accumulated in lakes and swamps
has not yet been removed, and the whole area appears level
and flat, although it really presents as great variety in alti-
tude as the apparently much rougher country outside, if we
disregard the immediate effects of stream action in the latter
areas. These characters are much more evident in the south-
ern portion of this area, where the moraines are widely sepa-
rated, than in the northern, where they are crowded together.
North and east of each moraine formed by the Wisconsin
glacier, the soil tends to grow deeper and blacker, because the
moraine acted as a dam, holding back the natural drainage.
and producing a lake in which large quantities of vegetable
debris mixed with clay accumulated. The level of the water
in the former lake may sometimes be traced on the moraine
by an abrupt change in the character of the soil.
When the moraine is prominent or ises considerably
above the general level, flowing wells are frequently struck
in the area covered by the old lake bed, which draw their
supply entirely from the annual rainfall upon the moraine.
The water sinks into the outcropping gravel beds described
above, and as the surface of the lake bed is lower than the
moraine and there is no escape from the pocket, the water
rises to or above the surface. (Introduction 12.)
56
WATER SUPPLIES OF ILLINOIS.
Outside the Shelbyville moraine all this is changed.
The moraines of the Illinoian Ice Sheet are broken up into
short ridges or clusters of mounds. (Introduction 13.) The
streams have many small branches. (See glacial map.) A
fairly complete drainage exists. The black soil has mostly
disappeared. The surface presents a series of broad shallow
V shaped valleys, with perhaps a sharper V forming the im-
mediate channel of each stream, the larger valleys being
separated by sharp, or flat but narrow, divides. In short
the surface of this area has the characteristics of maturity,
while that within the moraine is evidently in the formative
stage. The change is abrupt and marked as we pass from one
area to the other, but nature's forces are still at work and in
time will reduce the area within the Shelbyville moraine to
the same condition as that outside. Man, by underground
drainage, has interfered with and may delay this outcome for
centuries, but nature is more powerful than the resistance
offered and will surely triumph in the end.

much attention as
of the condition
In organizing the work of the Water Survey in the Au-
tumn of 1895, it was decided to devote as
was practicable to the investigation
of the Illinois River. To this end, arrangements
were made for the collection and examination of
samples of water from the Illinois River at sev-
eral points between its origin, at the junction of the
Desplaines and the Kankakee near Morris, and its discharge
into the Mississippi at Grafton. At the same time provision
was made for the collection and analysis of water samples
from Lake Michigan at Chicago, from several of the larger
tributaries of the Illinois, and from the Mississippi River
above and below the mouth of the Illinois.
The series of examinations begun at this time have, with
some minor changes as to places of collection, been more or
less continuously prosecuted until the present. Owing to the
meager financial support afforded to the Survey and the press
of other important investigations concerning the water sup-
plies of the State, the discontinuance of a portion of the
work upon the Illinois River was contemplated early in 1899,
but at this juncture a proposition from the Honorable Arthur
R. Reynolds, M. D., Commissioner of Health of the City of
Chicago, led the Board of Trustees of the Chicago Sanitary
District to make provision for an extensive series of examina-

tions of these same waters, a part of which work was carried
on here in connection with the work of the Water Survey.
The results of the work done here on behalf of theChicago
Sanitary District are to be published by the Trustees of the
District and are not included in detail in this report, but be-
cause of their close connection with our own investigations,
which they at certain points of time and place overlap, they
are sometimes referred to, and some of the general conclus-
ions which are stated in this report are based in part up-
on data which were obtained in the work done for the Chi-
cago Sanitary District, This relates particularly to refer-
ences to the condition of the several streams at points where
examinations were made on behalf of the Sanitary District
but not primarily as part of the Water Survey investigation;
Henry, Wesley City, Pekin, Beardstown upon the Illinois
River; Chain of Rocks upon the Mississippi; West Alton upon
the Missouri, and Bridgeport upon the Illinois and Michi-
gan canal, being cases in point.
THE ILLINOIS RIVER* is formed by the confluence of the
Desplaines and the Kankakee Rivers at a point ten miles north-
east of Morris and fifty-two miles southwest of Chicago.
The DesplainES, rising in the southeastern extremity of
Wisconsin, flows south, generally at a distance of about
twelve miles from Lake Michigan, to the vicinity of Chicago
sixty-two miles, thence southwesterly about forty-two
miles to its junction with the Kankakee. Its nor-
mal water supply comes largely from marshy districts,
but its flow is extremely variable, because of the very rapid
run-off in times of heavy rain or sudden thaws. Its waters
are charged with organic matters from marshes and in late
years its upper section receives considerable local sewage
from suburbs of Chicago,
At and below Lockport, it has for many years been seri-
ously polluted by the discharge of Chicago sewage from the
Illinois and Michigan Canal, and it also receives most of the
sewage of Joliet.
THE KANKAKEE RIVER rises to the west of the middle
of the northern border of Indiana, and flows in an extremely

sinuous course but in a generally westerly direction to its con-
fluence with the Desplaines. About two-fifths of its water-
shed area of 5,146 square miles consists of swamps and mar-
shes, and its waters contain considerable organic matters de-
rived from marsh vegetation. No very large towns are situ-
atedupon its watershed, and the quantity of sewage dis-
charged into it is comparatively inconsiderable, that of Kan-
kakee, the largest town (pop. 1900, 13,995) being the most
important.
Gaugings and estimates of the discharge of the Kanka-
kee River at its mouth indicate that the range is between 420
ft. per second and about 30,000 cu. ft. per second;
the mean flow being probably about 5,000 cu. ft. per second,
and ordinary low water flow, 1,300 cu. ft. per second.
cu.
From the junction of its two head water streams, the Illi-
nois flows almost due west to the neighborhood of Hennepin
about sixty miles, then turns abruptly to the south and follows
a southwesterly course about 196 miles to its mouth, a total
length of 256 miles. Throughout much of its course the
stream consists of a series of wide expansions or pools, alter-
nating with narrower stretches. In the alluvial section of
the river, which extends from Utica, about nine miles below
the mouth of the Fox, to the Mississippi, nearly 220 miles, the
numerous lakes, pools, bayous, swamps and sloughs, together
with the extensive lowlying bottoms, many of which in time
of high water are flooded to a breadth of one and a half to
six miles from the channel, serve by their storage capacity
to retard and equalize the flow and constitute a very important
factor in affording time and opportunity for the progress of
processes involved in the natural purification of the waters of
this stream.
THE FOX RIVER. -The largest tributary of the upper
Illinois is the Fox River, which rises. in the lake

The largest of them, the Sangamon, with a drainage area of
5,670 square miles, goes almost dry nearly every autumn, but
in times of freshet, floods its extensive bottoms for several
miles in width. The run-off is rapid, and except in times of
prolonged heavy rain fall, high water continues for but short
periods. The sewage of several towns is discharged into the
Sangamon, notably that of Springfield (pop. 34,159, 1900),
which enters about sixty-five miles above its mouth.

WATER SUPPLIES OF ILLINOIS.
THE POLLUTION AND THE SELF-PURIFICATION.
OF THE WATERS OF the
ILLINOIS RIVER.
The sources of pollution of the Illinois River include the
surface wash from its fertile and populous watershed; the
discharges of the sewage and manufacturing wastes of vari-
ous fair sized towns situated upon its banks or upon the
banks of is tributaries, by far the most notable of which are
contributed by Peoria and Pekin; and the introduction of
Chicago's sewage through the Illinois and Michigan Canal
and the recently opened Sanitary Canal.
The streams are natural drainage channels, and pollution
from the sources indicated is a natural result of the settling
of the land and the building of cities; it originates largely in
man's wasteful habits and the crudity of his efforts to dispose
of the so-called wastes of habitation,
Although in the aggregate the run-off or surface wash
probably carries much greater quantities of objectionable sub-
stances into this stream than does the discharge of sewage,
yet, since this is, in the main, coincident with high water,
more attention is in general, directed to the effect of the unusual-
ly great dilution thereby effected than to the impurities which
are thus introduced.
CHICAGO SEWAGE IN THE ILLINOIS RIVER.
For more than forty years, i. e., since the year 1860, the
sewage of the city of Chicago has been in part conveyed
through the Illinois and Michigan Canal into the Desplaines
River and thence into the Illinois River. The pumping
works, capacity 20,000 cubic feet per minute, erected in 1859-
60 at the junction of the canal with the Chicago River, were
originally established merely for the purpose of supplying the
canal with water from the Chicago River in time of drouth,
when the ordinary sources of supply failed, and the pumps

63
were kept in operation only during such periods as the inter-
ests of commerce upon the canal required a supply of fluid
from this source. Incidentally the operation of the pumps
effected an occasional flushing and notable purification of
the Chicago River.
In 1865, arrangements were made between the Board of
Works of the City of Chicago and the Canal Commissioners,
to utilize the pumps more extensively for the purification of
the river, and they were put in operation at various times
when the offensiveness of the river became more than usually
unbearable. Pumping was not, however, at this time re-
garded as an entirely satisfactory or permanent means of se-
curing relief, and in this same year the work of deepening
the Summit level of the canal sufficiently to secure a gravity
flow from the Chicago River, through twenty-nine miles of
the canal to Lockport and thence into the Desplaines River
at Joliet, was begun, the city of Chicago assuming the cost.
After six years' labor, this work was accomplished, and
in 1871 the first gravity flow from Lake Michigan through
the Chicago River, the Illinois and Michigan Canal to the
Desplaines River and thence through the Illinois River into
the Mississippi was established.
The deepening of the Summit level had been expected to
provide a gravity flow of 20,000 to 25,000 cubic feet per
minute,* but as the excavation seems to have been incomplete
at certain points, it is doubtful whether so great a flow as
this was ever secured except in time of freshets. By the year
1876,† the sliding in of the banks and the washing in of silt
from the Ogden-Wentworth and other ditches had so filled
up the canal that the flow probably did not ordinarily exceed
10,000 cubic feet per minute, and the effect in relieving the
Chicago River of its burden of pollution was far less than
the needs of the situation required. The city was growing
rapidly and the slaughtering and manufacturing industries
were enormously increasing, so that notwithstanding the
diversion of part of the sewage into the canal, the river be-
came even more and more offensive, and the people of the

t
city suffered not only from the disagreeable and offensive
character of the putrefying contents of an immense stagnant
cesspool or septic tank situated in their midst, but in times of
freshet or at times when the natural level of the water in the
lake was depressed, immense volumes of filth from this source
entered the lake and polluted the water which was drawn
into the mains for the general supply of the city. Along the
lake shore many sewers discharged directly into the lake,
but probably no such discharge of ordinary sewage could at
all compare in general offensiveness with the discharge of
the river.
As the gravity flow had proved to be inadequate, modifi-
cations in the canal, including the re-establishment of the
lock at its junction with the Chicago River, were effected,
and pumps with the nominal capacity for raising 60,000
cubic feet of water per minute from the river into the canal,
were erected at Bridgeport and set in operation June 3,
1884. However, these measures were found to be insufficient
for the existing needs, and they made no provision for the
disposal of the additional sewage resulting from further in-
crease in population and industries.
As a result of investigation and agitation by the Chicago
Citizens' Association during the period 1880-1885, and a reso-
lution passed by the city council in January, 1886, a Drainage
and Water Supply Commission was appointed by Mayor Har-
rison. The report of the investigations of this commission
and of Dr. John H. Rauch, Secretary of the State Board of
Health, led to the passage by the Legislature of the Act of
1889 creating the Chicago Sanitary District, and authorizing
the construction of the main Drainage Channel or Sanitary
Canal. The work of excavating was formally inaugurated in
September, 1892, and during the succeeding seven years the
project was so far advanced that the main channel was opened
January 17, 1900, since which time from 200,000 to 300,000
cubic feet per minute of the mixture of Chicago sewage and
diluting lake water have been flowing through this channel
into the Desplaines River valley at Lockport, with the result
that the condition of the major part of the Chicago River is
very greatly improved, and the offensive character of the dis-
charges into the Illinois River moderated. The conditions in

the Illinois and Michigan Canal, from Bridgeport to Joliet,
however, remain in certain respects much as they were, be-
cause the supply, which, for purposes of navigation, is still
pumped into it at Bridgeport, comes from the South Fork,
which receives the sewage of the stockyards district, and
which, owing to delays in the construction of the 39th Street
sewer or conduit, has not yet been flushed out.
THE CHEMICAL EXAMINATIONS.
In discussing the effect of the discharge of Chicago's
sewage into the Illinois River we shall first consider, more or less
briefly, the character of the water as revealed by the analyses
and the local conditions at each point, in consecutive order
from the Lake to the Mississippi.
1. LAKE MICHIGAN AT CHICAGO.-The results of our
chemical examinations of the waters of Lake Michigan
drawn from the lake through the 14th Street four mile crib,
are shown in detail in the tables upon pages 230-237 inclusive.
The variations during the four years covered in this re-
port were in general but slight and were occasioned chiefly
by conditions which caused discharges from the Chicago
River and from those sewers which empty directly into the
lake, to pass farther out than they commonly do; they are in
part due also to storms which stir up the sediments near the
shore and the cribs, the sediments being in the main such as
are of course natural to any considerable body of surface
water, but also including refuse from the city and filth
dredged from the Chicago River.
That the lake water is ordinarily fairly well charged with
dissolved oxygen is shown by the results of numerous deter-
minations which are exhibited graphically by the curves in
Plate XXXIX.
2. ILLINOIS AND MICHIGAN CANAL at Lockport.—The
fluid pumped from the south branch of the Chicago River
into the Illinois and Michigan Canal at Bridgeport flows.
sluggishly for a distance of about twenty-nine miles to Lock-
port, where the first discharge from the canal into the Des-
plaines River occurs, the discharge being occasioned by the
use of canal water as hydraulic power to run the Norton
Mills, situated at this point.
66
WATER SUPPLIES OF ILLINOIS.
Four miles farther down, the water from the canal dis-
charges directly into the Desplaines River at Joliet, the canal
at this point crossing the river by means of a dam and pool.
Before the opening of the Drainage Channel, the liquid
pumped into the old canal at Bridgeport constituted the major
part of Chicago's sewage. It contained, and still contains,
both house sewage and manufacturing wastes; the latter in-
cluding drainage and refuse from stockyards, rendering es-
tablishments, soap factories, metallurgical and chemical
works, gas works, etc., etc. Ordinarily no appreciable dilu-
tion and no notable additional pollution occurs between
Bridgeport and Lockport, but in certain seasons water from
ditches and formerly also from the Desplaines River, in ex-
cessive freshet, flowed into the canal.
The concentration of this liquid and the nature of the
manufacturing and other wastes contained in it is such that
no very considerable change in the quantity or the character
of the organic matters appears to take place between Bridge-
port and Lockport, a fact demonstrated by comparative analy-
ses made by the State Board of Health and others made by
ourselves for the Sanitary District of Chicago, the data of
which are embodied in the report of the investigations made
on behalf of the Sanitary District, and which consequently
are not included in this report.
The analyses of the water of the canal at Lockport serve to
show the character of the water as it was discharged into the
Desplaines valley in part at Lockport, and in part at Joliet,
four miles below.
The results are given in the tables upon pages 102-109
inclusive, and upon pages 192 and 193. The data reveal nota-
ble variations, generally in April and March, the usual season
of freshets, but for most of the year they show a somewhat
remarkable uniformity in the proportions of organic matters.
Inspection of the yearly averages, which are brought to-
gether in Table III, below, shows that up to the time of
the opening of the Drainage Channel there were, in most re-
spects, but slight variations from year to year, such changes as
did occur being in the direction of a small but constant in-
crease of the nitrogenous organic matters.

Examination of the data of the analyses for the year
1900 upon pages 108 and 109, and those for the year 1901
upon pages 192 and 193, reveal much greater and more fre-
quent variations than occurred before the opening of the
Drainage Channel. An inspection of the averages which are
brought together in Table IV below, shows that the rel-
ative proportions of organic matters were considerably reduced
as a result of the diversion of part of the sewage to the new
Drainage Channel, though the proportions of nitrogen as free
ammonia became greater than before, a result which may be
due to the effect of the greater dilution in facilitating the
more speedy, oxidation of the organic matters.
The variations are mainly due to the fact that at times
when the lake is high or the discharge from the Drainage
Channel at the controlling works is reduced, comparatively
pure lake water backs up into the South Fork in such volume
that a more dilute sewage than usual is raised by the pumps
into the old canal, while ordinarily, inasmuch as the South
Fork is not yet flushed out, the liquid pumped into the old
canal still consists of the comparatively concentrated sewage
from the Stockyards district.

3. DESPLAINES RIVER AT LOCKPORT.--The Desplaines
River itself at Lockport is a small stream of exceedingly varia-
ble flow.* Above this point the river receives sewage from
various suburban towns. For the purposes of this investiga-
tion, effort was made to have the samples collected beside the
old stone bridge above the point at which any discharge from
the Illinois and Michigan Canal enters the stream but through
some misunderstanding of the collectors, it is probable that
the samples for 1897 and 1898 were at times collected at some
point reached by the discharge of the tail race of the Norton
Mills, for frequently they unmistakably consisted of mixtures
of Upper Desplaines River water and water from the canal.
Except in times of freshet or prolonged wet weather, the wat-
ers of this stream have but slight effect upon the sewage flow-
ing past Joliet. The data of the analyses are given in the
tables upon pages 110-115 inclusive; for reasons stated above,
only the data for 1899 can be considered representative of the
Desplaines River water before mixing with Chicago sewage.
4. THE SANITARY CANAL OR MAIN DRAINAGE CHANNEL
At Lockport: After the opening of the main Drainage Chan-
nel, samples of water were collected from it just above the
point of discharge into the Desplaines Valley, that is, just above
the Bear Trap Dam or controlling works. The analyses for

69
1900 are given in detail upon pages 116 and 117, and for 1901
they appear upon pages 194 and 195. The variations which
appear in the analytical data are due in the main to variations
in the volume of flow in the Drainage Channel,* caused partly
by differences in the lake level, partly by the partial closing of
the gates at Lockport, and also at certain times by the over-
flow of water from the Desplaines River, at the spillway,
into the Main Drainage Channel itself; further they are caused
in part by variations in the pumping at Bridgeport, *for when
the Bridgeport pumps are not in operation, a portion of the
contents of the South Fork enters the South Branch and pas-
ses thence into the main Drainage Channel, while when the
pumps at Bridgeport are kept in operation, practically all of
the sewage from the South Fork is discharged into the old canal
and enters the Desplaines River below the point of discharge
from the Drainage Channel. The yearly averages are given
in Table V below.

5. THE DESPLAINES RIVER AT JOLIET.-At Joliet, which is
four miles below Lockport, the Illinois and Michigan Canal
crosses the Desplaines River by means of the pool or basin
formed by dam number one, which is located in the upper part
of the town, the Canal from this point on passing down be-
side the west bank of the river to its terminus at La Salle.
It is between this dam and Lockport that the discharges

the discharge from the Drainage Channel, enter the Desplaines
Valley and mix with the waters of the Desplaines River, con-
sequently this is the point at which the initial effect of the
discharge of Chicago sewage is at the maximum.
Prior to the opening of the Drainage Channel the season-
al variations in the composition of the water at this point
were considerable because of the variations in flow of the dilut-
ing waters of the Upper Desplaines. During much the
greater part of the year, especially the summer and autumn
seasons, the dilution of the concentrated sewage discharged
from the old canal was very slight, but in the earlier or flood
season of the year, the flow in the Desplaines at this point
would occasionally amount to three or four hundred thousand
cubic feet per minute, and the dilution of the sewage be cor-
respondingly great, i. e. ten to one. In the summer season,
when the natural flow in the Upper Desplaines generally
dwindles to almost nothing, there was practically no dilution,
the 36,000 cubic feet per minute of sewage discharged by the
canal constituting the entire flow. Indeed, the river bed below
the dam at Joliet would at times be almost dry, the flow for
some distance below this point being entirely carried by the
canal. Since the opening of the Drainage Channel, the vol-
ume* of water passing this point is much more uniform. The
effect of the dilution* of the sewage is seen in the very great
difference between the data of the analyses of samples taken
before and those taken after the opening of the Drainage
Channel.
Analyses of the waters of the river at this point were
made in 1899 and 1900 for the Sanitary District. The details
are not given in this report but the averages of the results for
these two years are given in Table VI upon page 71.
During the year 1900 also there were often great varia-
tions in the proportions of the various constituents of the
water. These variations were in part due to seasonal varia-
tions of flow in the Upper Desplaines and in part the result
of variations in the flow in either the Illinois and Michigan

Canal or the Drainage Channel or both, for when for any rea-
son the flow in the Drainage Channel is reduced or stopped by
manipulation of the gates at Lockport, sewage accumulates
in the Chicago River and the discharge into the Desplaines
consists chiefly of the more concentrated sewage of the old
canal, and when the gates are again opened, a much less di-
lute mixture of the accumulated sewage is for a time discharged
by the new canal. However, many of the variations hitherto
noted were due to incomplete mixing of the several bodies of
sewage and water which come together in this vicinity, a fact
that is shown particularly by the results obtained from the
two series of analyses made during 1901. During this year, a
sample was taken at each side of the river at dam number one
at Joliet. The averages for the year and also the mean for
the two series are shown in Table VI below.
Comparison of the averages for 1900 and 1901 with those
for 1899, makes evident the great difference in concentration
of the sewage passing Joliet after the opening of the Sanitary
Canal. Most of the sewage of Joliet enters the stream below
the point at which the Joliet samples were collected.

KANKAKEE RIVER AT WILMINGTON.-Until the Chi-
cago Main Drainage Channel was opened, the sewage dis-
charged through the Illinois and Michigan Canal met with
its first notable dilution, usually, only upon mixing with the
waters of the Kankakee, for although at times the flood flow
in the Desplaines would, for a few days, equal, or even exceed,
the mean flow in the Kankakee, i. e., would amount to from
300,000 to 400,000 cubic feet per minute, and dilute the sewage
eight or ten times, yet the main flow of the Desplaines for the
year is but one fifteenth to one tenth that of the latter stream,
and the ordinary low water flow is proportionally even less.
The data of the analyses are given on pages 214 and 217
inclusive and upon page 225. The yearly averages are brought
together in Table VII, page 73.
Inspection of the figures of the detailed analyses shows
that there are notable variations in the composition of the
waters of the Kankakee during the year. In general the var-
iations are greatest in the spring of the year when freshets
bring down much suspended matters, both mineral and organic;
but it will be noticed that there is a considerable diminution
in the proportions of nitrates during the warm summer
months, this diminution doubtless being in part the result of
the growth of vegetation in the flowing waters of the stream,
in part the result of assimilation of nitrates by the vegetation
of the headwaters in the Kankakee marshes, which during
this portion of the year constitute the chief source of supply.
The higher nitrates during the high water season are in part
due also to the leaching of nitrates from the soil by the run-off
and the discharges from tile drains, which occur chiefly during
the seasons of lower temperature and greater precipitation,
which are consequently of course the seasons of high water.
The organic matters contained in the waters of this stream
are almost entirely of vegetable origin, for no considerable
amount of sewage is discharged into it, that of Kankakee
(population 13,995), about 35 miles from the mouth and 25
miles above the point of collection, being the most important.

7. THE ILLINOIS RIVER AT MORRIS.-At this point, the
first station upon the Illinois River proper, the stream con-
sists of an incomplete mixture of the sewage-laden waters of
the Desplaines with the waters of the Kankakee.
·
Prior to
the opening of the Drainage Channel, the Chicago sewage
discharged into the Desplaines River experienced no consider-
able dilution before meeting the waters of the Kankakee,
except when the Desplaines itself was in flood, which rarely
was the case at times other than those of the usually short
spring freshets.
When the Kankakee was in flood, the dilution at this
point was of course correspondingly great (as much as fifty
to one), the average dilution for the year being about ten to
one, but ordinarily in the summer and autumn the dilution
would probably rarely exceed two or three to one and often
would fall far short of this. Since the opening of the Drain-
age Channel, the flow in the lower Desplaines is far more
uniform, and the average is just about equal to the average
flow of the Kankakee, which is 300,000 cubic feet per minute.

WATER SUPPLIES OF ILLINOIS.
The details of the analyses appear upon pages 118-122
inclusive and pages 124-125. The yearly averages are brought
together in Table VIII below.
In considering the data of the analyses for Morris, it must
be remembered that at this point the mixing of the waters is
imperfect, and that the individual analyses consequently may
appear to vary more than the mean composition of the incom-
plete mixture really warrants; but it is not likely that the
variations thus occasioned are, for this point, sufficiently
great to seriously affect the yearly averages and the compari-
sons instituted between them.

8. THE ILLINOIS RIVER AT OTTAWA.
The collections at
this point were made about a mile above the mouth of the
Fox River and above the point where the sewage of the town
and some discharge from the Illinois and Michigan Canal
enter the stream.
:
75
THE ILLINOIS RIVER.
The data of the analyses are shown upon pages 123, 127
and 136 and the averages are shown in Table IX.
The analyses show the changes which take place during
the flow of 24 milés from Morris to Ottawa without further
dilution and without notable addition of impurities, but the
mixing of the discharges from the Desplaines and Kankakee
is not yet complete and some variations of the analyses are
due to this cause. It is to be noted that at this point the
nitrites are found in the waters of the Illinois River in greater
proportions than at any other point along its course, which
fact, taken into consideration with the other indications of
the analyses, shows that it is in this stretch of the river that
the final oxidation processes which convert the organic mat-
ters of the sewage into innocuous mineral matters, the nitrates,
etc., are most active and effective.

9. THE FOX RIVER AT OTTAWA.-The Fox River is the
largest tributary of the Upper Illinois proper, and next to
that of the Kankakee River, its discharge is the most impor-
tant diluting factor of the Upper Illinois. Its discharge is
more uniform in volume than that of the Desplaines River
and is greater in proportion to its watershed area.
The sample for analysis was collected above the town of
Ottawa and above the aqueduct which carries the water of
the Illinois and Michigan Canal across the stream. The
waters of the Fox are rather highly charged with organic
matters which are mainly derived from the vegetation which
is abundant in the upper stretches of the stream, as well as
in the marshes and shallow lakes which constitute the chief
sources of its headwater supply.
The stream receives the sewage and manufacturing
wastes of a number of towns, of which Elgin (population 22,433)
and Aurora (population 24,147) are the largest. Between these
two towns is the town of Geneva, where there is a large Glu-
cose Works, in which 40,000 carloads of corn are used annually,
the wastes from which, probably at least 150 tons of highly
nitrogenous organic refuse daily, are discharged into the
river.
Below Aurora comparatively little sewage and wastes
enter the stream and there is considerable opportunity in the
flow of 50 miles between Aurora and the mouth for the nat-
ural purifying processes to exert their influence in bettering
the condition of the water.
The data of the analyses are shown in detail upon pages
218 to 224 and the averages are brought together in Table
IX above.
10. THE ILLINOIS RIVER AT LASALLE.-The sample at
LaSalle was taken beside the wagon bridge at a point which
is three miles below the mouth of the Big Vermilion River,
but above the point at which most of the sewage of LaSalle
and the final discharge from the Illinois and Michigan Canal
enters the river.
Between Ottawa and LaSalle, the conditions in the river
are such as favor the abundant growth of vegetation and the
waters at this point consequently become charged with organic
THE ILLINOIS RIVER.
77
The nitrates
matters to a greater extent than at Ottawa.
also are found at this point in greater proportion than they
are found at Ottawa and have not been very notably reduced
in proportion by the dilution resulting from the discharge
through the Chicago Main Drainage Channel, a fact which is
noted from comparison of the averages for the four years
preceding and those for the year following the opening of
the Drainage Channel. From Lockport to Ottawa the mix-
ing of the waters seems to be at no point complete, and varia-
tions in the analyses due to this imperfect mixing are
frequent, but study of the conditions at LaSalle, including
analyses of cross-section samples, has shown that at this point
the waters have ordinarily mingled completely.
Just below the town of LaSalle there occurs the final dis-
charge from the Illinois and Michigan Canal, which carries
most of the sewage of LaSalle, and the discharges of sewage
and manufacturing wastes from the town of Peru.
It should be noted that at several points between Joliet
and LaSalle there are minor discharges from the Illinois and
Michigan Canal into the Desplaines River and the Illinois
River, and that prior to the opening of the Drainage Channel,
the old canal at times carried practically undiluted Chicago
sewage throughout much of the 66 miles of its lower course.
Indeed, in periods of low water the canal often carried the
entire body of Chicago sewage past Joliet and discharged it
at various points many miles below that at which it is now
delivered into the river, thus carrying the pollution much far-
ther down stream than the points at which it is now found.
Since the opening of the Drainage Channel, the diluted
sewage which enters the stream between Lockport and Joliet
is mainly carried by the Desplaines and Illinois rivers and the
volume discharged from the canal at points below Joliet con-
stitutes a much smaller proportion of the volume of the river;
moreover, the water of the canal is now in far better condition
because of its great initial dilution at Joliet and the more
thoroughgoing natural purification thereby occasioned. The
detailed analyses for LaSalle are given upon pages 128-130
and 132-135, and the yearly averages appear in Table X,
page 78.

11. The Big Vermilion River is the most important
tributary between Ottawa and Peoria. The discharge of this
stream varies between rather wide limits, but is an important
diluting factor only during the freshet season. In the drier
season its flow is practically nothing but sewage, derived
mainly from the towns of Pontiac and Streator and from the
drainage of factories and mines upon its banks. The stream
is used as a source of water supply for the towns of Pontiac
and Streator and during much of the year the entire flow of
the stream above these towns is used for water supply, and
thus transformed into sewage is discharged again into the
stream below the respective towns.
The samples for analysis were collected about half a mile
within the mouth of the stream, the mouth being about
three miles above the wagon bridge at LaSalle.
The analyses are not printed in detail in this report but
the yearly averages are given in Table XI, page 79.

12. THE ILLINOIS RIVER AT AVERYVILLE.--The samples
were collected at midstream at the bridge over the narrows,
three miles above the Peoria Court House and about 60 miles
below LaSalle, at a point not affected by the sewage of Peoria.
Between LaSalle and Averyville there is no considerable
additional dilution and no great amount of impurities intro-
duced except that discharged from the Illinois and Michigan
Canal just below LaSalle, which contains most of the sewage
of LaSalle, and the sewage and manufacturing wastes of
Peru, just below LaSalle.
The data of the analyses are shown in detail upon pages
137 to 143 inclusive and pages 200 and 201. The yearly aver-
ages are brought together below in Table XII.
The study of the data of the analyses and particularly
comparison with those for the other points along the river
between Averyville and Lockport show unmistakably that a
very great purification of the waters of the stream takes
place as they flow along the 125 miles of its course between
these two points.
The seasonal variations in the water of the river at
Averyville, as may be seen by study of the detailed analyses,
are quite considerable, but the limits of variations are in
80
WATER SUPPLIES OF ILLINOIS.
most respects considerably less since the opening of the Chi-
cago Drainage Channel than they were formely.
The variations of the chlorine are shown diagramatically
upon Plate VII. It is quite natural under the existing cir-
cumstances that the proportions of chlorine should be smaller
during the high water period, that is, in February, March
and April, and that in the later season of the year, the warm
summer months when the flow is very much reduced, the con-
tent of chlorine should be much greater than at other periods.
Plates VIII and IX show graphically the seasonal variations
in content of free ammonia. It is very noticeable that both
before and since the opening of the Chicago Main Drainage
Channel, the proportions of free ammonia are much greater in
cold weather than at other seasons, and it is evident too that the
proportions of free ammonia contained in the water are much
less since the opening of the Chicago Drainage Channel than
they were before that time.
Plate X shows the seasonal variations in the proportions
of nitrites in the Illinois River water at Averyville. The
curves of the plate show at a glance that the period when
nitrites are most abundant in the Illinois River water at
Averyville is in general the summer time or early autumn,
when the flow is at the minimum and the temperature at the
maximum, the conditions with respect to nitrites being just
the opposite to those referred to above with respect to free
ammonia. It is evident from the figures in the tables of
analyses, and it is shown graphically upon the plate, that the
proportions of nitrites since the opening of the Drainage
Channel are in general less throughout the year than they
were before the opening.
Comparison of the figures of Table XII below shows
that as a result of the dilution effected by the opening of the
Chicago Main Drainage Channel, the proportions of the
various significant constituents of the water of the Illinois
River at Averyville are very greatly reduced. The data
throughout show this: the chlorine has been reduced from
30.2 parts, the average for the three years prior to the opening
of the Drainage Channel, to 17.5 parts, the average for the
two years subsequent to the opening; similar reductions in the
THE ILLINOIS RIVER.
81
quantities of oxygen consumed, both the total and that con-
sumed by dissolved and by suspended matters, are evident; that
the nitrogenous organic matters are very much reduced in
proportions, is evidenced at once by comparison of the relative
quantities of nitrogen as albuminoid ammonia, and the total
organic nitrogen for the two periods; moreover, the propor-
tions of nitrogen as free ammonia contained in the water
since the opening is less than two-thirds that contained in
the water at this point before the opening.
Comparison of the proportions of nitrites shows a very
great decrease here since the opening of the Drainage Chan-
nel, the quantity being less than one-half that formerly con-
tained. That the reduction of these constituents is not
wholly due to mere dilution, but that, in part at least, it is
due to a greater proportional destruction of the organic mat-
ters discharged into the stream at Lockport and Joliet, would
seem to be evident from the fact that the nitrates are found
in greater proportions in the water at this point than they
were before the opening of the Drainage Channel.

WATER SUPPLIES OF ILLINOIS.
Comparison of the figures of Table XII for Averyville
with those of Table X for LaSalle show that there has been
a very great decrease in the organic matters during the flow
of 60 miles between the two points. The diminution is very
considerable in each case, even including the nitrates, but the
most significance attaches to the marked diminution in the
proportions of nitrites and free ammonia and albuminoid and
total organic nitrogen.
The proportions of nitrites have been reduced about 50
per cent., which would appear to indicate that the nitrifica-
tion processes are approaching completion, this in turn indicat-
ing that those organic substances which are easily suscep-
tible to bacterial action have, in great part, already been con-
sumed. In fact it is highly probable that the refuse animal
matters introduced in the sewage of Chicago have been com-
pletely destroyed, and that the organic matters which are
contained in the river water at this point are derived from
vegetable and not from animal sources; in fact vegetation of
various forms, the plankton, etc., is exceedingly abundant in
the river between LaSalle and Averyville. The water of the
river between these points and especially near Averyville may
often be seen covered with floating masses of vegetation con-
sisting largely of filamentous and other algae.
Comparison of the averages for Averyville with those for
the tributary streams serves to show that the waters of the
Illinois River at this point contain considerably less organic
matters than is contained in the waters of its chief tributaries,
which latter have never been in contact with Chicago sew-
age, although, of course, they receive some sewage from com-
paratively small towns. It is very evident, of course, that
free ammonia and nitrites are still present in the waters of
the Illinois at this point in greater quantities than are con-
tained in most of the tributary streams, but the considerations
detailed above and all available data show unmistakably
that the character of the water in the stream at Averyville is
now far better than it was before the Chicago sewage re-
ceived its initial dilution at Chicago and not at the junction
of the Desplaines and the Kankakee sixty miles nearer the
point under consideration.

13. THE ILLINOIS RIVER AT HAVANA.--Collections at
this point were made about a mile and a half above the town
and above the mouths of the Spoon River and Quiver Lake.
Between Averyville and Havana, sewage and manufacturing
wastes are introduced into the river at Peoria and Pekin in
quantities second only to those introduced through the Chica-
go Drainage Channel and the Illinois and Michigan Canal.
These, however, consist very largely of refuse from stock
yards, from the cattle sheds where some 40,000 cattle are fed
upon distillery slops, and the wastes from large glucose
works, etc., etc. Prior to the opening of the Chicago Drain-
age Channel, the condition of the river along this stretch of
45 miles was, during the summer time at least, practically
that of an immense septic tank, the offensive condition of
which was striking throughout, but was greatest in the near
vicinity of Peoria and Pekin.
The data of the analyses are shown in detail upon pages
144 to 151 inclusive and the yearly averages are brought
together in Table XIII below.
The data of the detailed analyses show seasonal varia-
tions similiar to those which were found at Averyville, and com-
parison of the yearly averages with those for Averyville show
that, notwithstanding the introduction of an enormous amount
of filth between Averyville and Havana, the putrefactive and
other purifying processes going on in the waters of the stream
have been sufficient to reduce the proportions of the various
constituents so much that they were but slightly different at
Havana from what they were at Averyville, although analyses
of samples taken at Wesley, just below Peoria, and also at a
point just below Pekin, show a notable increase in the content
of organic matters at these two points, above the quantities
found at Averyville and above those found at Havana, 30
miles below Pekin.
Comparison of the figures for the year 1900 with those of
the years 1896 to 1899 inclusive (Table XIII) shows the effect
of the opening of the Chicago Drainage Channel in reducing
the proportions of the various constituents here considered.
With the exception of the nitrates, the reduction of the various
constituents is very considerable. The fact that the nitrates
84
WATER SUPPLIES OF ILLINOIS.
are not proportionally lowered seems to indicate that the oxida-
tion at this point is more complete since the opening of the
Sanitary Canal than it was previously.
Numerous determinations of dissolved oxygen in the wa-
ters of the Illinois at Havana, covering several years [1895-
1898], show that, although at times the water is saturated, in
general the content of dissolved oxygen is considerably less
than that required for saturation, and at all times the dis-
solved oxygen diminished rapidly upon allowing the sample
to stand.'

SPOON RIVER AT HAVANA.—Collections were made
about half a mile within the mouth of the river. The Spoon
River drains a watershed area of about 1870 square miles, but,
as there are no very considerable towns situated upon the
stream or its watershed, it receives but little sewage and may
be regarded as one of the least polluted of the natural streams
of the state.
The data of the analyses are shown in detail upon pages
226 to 229 inclusive and the yearly averages are brought to-
gether in Table XIV below.

15. THE ILLINOIS RIVER AT KAMPSVILLE.--At this point,
thirty miles above the mouth of the Illinois River, the sam-
ples were collected just above the United States Government
dam.
Samples have been collected here regularly each week
from July 23rd, 1896, to the present time, and the results of
the analyses, inasmuch as they cover three full years preced-
ing and three full years following the opening of the Chicago
Main Drainage Channel, afford an excellent opportunity for
judging the effects of the increased dilution of the sewage at
Chicago and Joliet upon the character of the waters of the
Illinois as they are about to flow into the Mississippi.
The series of analyses, which are shown in detail upon
pages 152 to159 inclusive, and pages 202, 203, 238 and 239,
make manifest the usual seasonal variations in the constitu-
ents of the water at this point. Some of the data are exhib-
ited graphically by the Plates XI to XVI.
The data represented in Plates XI and XII show that in
the usual high water period, that is the first half of the year,
chlorine is contained in the water of the river at this point in
just as considerable proportions as before the opening of the
Drainage Channel, but that in the latter part of the year,
which was formerly a period of extreme low water, the con-
86
WATER SUPPLIES OF ILLINOIS.
tent of chlorine is now found to be considerably less than
formerly.
Plate XIII exhibits the variations in the proportions of
free ammonia and shows the great difference, in respect to the
proportional content of free ammonia, between cold weather
and warm weather conditions.
Plate XIV, which represents the seasonal variations in
the proportions of nitrogen as nitrites. shows that these are
not contained in the river at this point in so great quantity as
they were previous to the opening of the Drainage Channel,
but that they follow the same general course of seasonal
changes as formerly, that is, they are least in cold weather,
greatest in hot weather.
Plate XVI shows, by means of monthly averages, the
proportions of total organic nitrogen and the seasonal varia-
tions which take place with respect to the content of nitro-
genous organic matters.
The yearly averages are brought together in Table XV
below.

Comparison of the averages for the three years 1897-8-9
with each other shows no very great variations in the organic
matters, though the oxygen consumed, the free ammonia and
the total organic nitrogen increased somewhat from year to
year, while the nitrites and nitrates decreased.
Comparison of the averages for 1900 with those for 1899
shows that immediately after the opening of the Drainage
Channel there was a notable decrease in the proportions of
the various constituents with the single exception of nitrates;
the decided increase of which, taken into consideration with
the 25 per cent. decrease in the proportions of nitrogen as al-
buminoid ammonia, indicates that under the new conditions
the oxidation of the organic matters is more complete. The
averages for 1901 correspond fairly well with those for 1900
except that the total organic nitrogen appears decidely higher,
but this is doubtless due to the fact that the data for this con-
stituent cover but the first nine months of the year, as press
of other work made it necessary to discontinue the determina-
tion. The higher free ammonia in 1902 is chiefly due to the
fact that in January and February, when the cold weather
conditions are usually accompanied with high free ammonia
in the Illinois River, the stage of water in the Illinois was
remarkably low and the concentration correspondingly great.
Comparison of the averages for the two three-year per-
iods makes evident the great diminution in the proportions of
the various constituents, except free ammonia, which is 393
parts per million in the latter period as against .371 parts in
the earlier period, and the nitrates, which have considerably
increased.
Plate XV exhibits graphically by means of columns some
of the facts shown in Table XV and facilitates the compar-
isions between the averages for the separate years.
THE ILLINOIS RIVER AT GRAFTON.-At this station
samples were collected from the Illinois River at a point about
two miles within the mouth, which is not reached by the
water of the Mississippi River.
There are several islands in the Mississippi River close
to the mouth of the Illinois lying parallel with and at no great
distance from the Illinois shore. The United States engineers
88
WATER SUPPLIES OF ILLINOIS.
in charge of this section of improvement of the Mississippi
River have had dikes built between these islands which pre-
vent the waters of the Illinois River from discharging into
the Mississippi River at the old mouth, but cause them to pass
down for at least two miles parallel with the Mississippi River
before finally entering the latter. In times of high water the
discharge from the Illinois River flows over these dikes into
the Mississippi River at points between one and two miles
above Grafton, and also at times the waters of the Mississippi
flow over them into the Illinois River. Our samples were col-
lected above the point at which this occasional mixing occurs.
The data of the analyses are shown in detail upon pages
160 to 163 inclusive and pages 204, 205 and 240, and the yearly
averages are brought together in Table XVI, page 89.
Comparison of the data of the analyses show seasonal
variations of considerable magnitude in the waters of the
Illinois River at Grafton, the most important of which, the
albuminoid ammonia and the total organic nitrogen, are shown
in Plates XXI and XXII. Comparison of the yearly aver-
ages shows a considerable improvement in the character of
the Illinois River water at this point since the opening of the
Chicago Main Drainage Channel.
17. THE MISSISSIPPI RIVER AT GRAFTON.—Samples were
taken at midstream at a point about two miles above Grafton
and above that at which any discharge from the Illinois River
enters the stream. The analyses, which are given upon pages.
164 to 167, 206 and 207, show that seasonal variations in the
constituents of the waters of the Mississippi River are in
many respects more frequent and more considerable than the
seasonal variations in the waters of the Illinois. This is espe-
cially true of the albuminoid ammonia and the total organic
nitrogen, as is evident upon consideration of the features of.

tions than in the waters of the Illinois in 1899, and were near-
ly fifty per cent. greater than the average for the three years
after the opening of the Chicago Main Drainage Channel.
The proportions of nitrogenous organic matters as repre-
sented by albuminoid ammonia and total organic nitrogen, as
is seen upon comparison of the general averages, were nota-
bly higher in the Mississippi than in the Illinois, although in
the year 1901 they were slightly higher in the latter stream.
On the other hand the oxidation products of nitrogenous
organic matters, represented by the free ammonia, the nitrites
and the nitrates, were present in the waters of the Illinois in
proportions which are two to three times those contained in
the waters of the Mississippi, and the total nitrogen, that
is, the sum of the total organic nitrogen, the nitrogen as free
ammonia and that as nitrites and nitrates, was 2.546 parts
per million in the Illinois against 1.585 in the Mississippi.
The preponderance of nitrogen in the waters of the Illi-
nois over the proportions contained in the waters of the Missis-
sippi is doubtless due to the fact that the watershed of the
former is more extensively and more intensively cultivated
than is that of the latter and that the industrial wastes which
are discharged into the Illinois are more highly nitrogenous
in character than are those which find their way into the
Mississippi. For example, the refuse matters discharged into
the Illinois River at Peoria and Pekin consist largely of the
highly nitrogenous wastes from glucose factories and those
resulting from the feeding of cattle upon distillery slops,
while the organic matters contained in the waters of the up-
per Mississippi are derived largely from the wastes of the
lumber industries. Both streams of course receive in the
aggregate enormous quantities of sewage.
DISSOLVED OXYGEN.-Determinations of dissolved oxy-
gen in the waters of the Illinois and the Mississippi rivers at
Grafton show that in general the waters of the Illinois con-
tain practically the same proportions of oxygen in solution as
do those of the Mississippi, although the stability of the or-
ganic matters, as measured by the partial disappearance of
the dissolved oxygen when the samples are allowed to stand

in the dark for 24 hours, is somewhat greater for the Missis-
sippi than for the Illinois.
The data of the analyses are not printed in this report,
but those obtained from shipped samples (24 hours between
collection and examination) are represented in the curves of
Plate XL.
From January 4th, 1900, to June 27th, the percentage of
saturation in shipped samples of the waters of the Illinois
ranged from 43 to 95.7, the minimum being found in samples
collected May 16th and examined 48 hours later; in no other
ease was less than 52.7 per cent. found and indeed in but five
other samples was less than 61 per cent. found. The average
for the 141 samples was 76.5 per cent.
A parallel series of samples from the Mississippi gave
55.8 per cent. for the minimum and 108.8 per cent. for the
maximum, with 82 per cent. as the average for the 127 sam-
ples. Similar variations and similar relations between the
two rivers are shown in Plate XL for the latter part of 1901.
Numerous determinations made upon the spot show that
the waters of both the Illinois and the Mississippi are fre-
quently supersaturated with dissolved oxygen, and also that
often both contain less than the saturation quantity, the
range being greater in the Illinois, but the average being
practically the same for both.
18. THE MISSISSIPPI RIVER AT ALTON.--For several
years, samples of water were collected at the intake of the
old Alton City Water Works and also a few samples were
collected at mid-stream, but in the fall of 1898 arrangements
were made for the collection of series of samples at a point
opposite the new water works, nearly a mile above the town.
At this place five samples were collected, at as many dif-
ferent points across the stream, for the purpose of determin-
ing the differences in composition due to the incomplete
mingling of the waters of the Illinois River with those of the
Mississippi. The point where these samples were taken is 16
to 17 miles below the mouth of the Illinois river at Grafton
and 6 or 7 miles above the mouth of the Missouri River, or 15
to 16 miles above the intake of the St. Louis Water Works at
Chain of Rocks.
92
WATER SUPPLIES OF ILLINOIS.
The data of the analyses are given upon pages 168 to 191
inclusive and some of them are represented graphically by
means of the Plates XXVI to XXIX.
Consideration of the data shows how incomplete is the
mixing of the waters of the Illinois with the waters of the
Mississippi, the facts being brought out especially by com-
parison of the proportions of chlorine contained in the waters
of the Illinois River and the Mississippi River above Grafton
with those found at different points in the cross section of the
stream at Alton.
Plate XXVI gives comparative curves representing the
results of chlorine determinations in the regular weekly sam-
ples for the years 1899 and 1900. Several times, in January
and February, when, because of stationary ice, it was imprac-
ticable to reach the proper points, the collections were made
at the ferry crossing opposite the town nearly a mile below;
and also at times during the same months, because of difficul-
ties resulting from the quantities of floating ice, the samples
were not collected at really representative cross section points
so that the data for parts of these two months, for both years,
show proportions of chlorine which are not truly representa-
tive for the Missouri side of the stream, because the collector
who started from the Illinois side could not get far enough
out toward the Missouri shore. Plates XXVII and XXVIII
represent the same data for 1899 and 1900 respectively, but in
the form of monthly averages.
Plate LI represents the proportions of Illinois River
water and Mississippi River water which constitute the mix-
ture at the different points across the stream. The calcula-
tions are based upon the average content of chlorine for the
year. They show that very little of the water of the Illinois
(4 per cent. Illinois water and 96 per cent. upper Mississippi
water) is contained in the mixture toward the Missouri shore
but that far the greater part of it passes down between mid-
stream and the Illinois shore.
The seasonal variations of free ammonia and also the
cross-section variations are shown in Plate XXIX. It is to be
noted that during much of the year there is little difference
between the proportions of free ammonia found at the differ-
THE ILLINOIS RIVER.
93
ent points, as also between the proportions found in the
Illinois and those in the Mississippi, and that at times more
free ammonia is found in the waters of the Mississippi than
in the waters of the Illinois.
19. THE MISSISSIPPI RIVER AT QUINCY.-Samples of
water were collected from the Mississippi River at Quincy at
a point near the end of the intake conduit of the Quincy
Water Works, which is at a point above that at which any
discharge of sewage from Quincy enters the river.
The data of the analyses are given on pages 208 to 214
inclusive and are partially shown in the diagrams on Plates
XXXII and XXXIII. A study of the data of the tables shows
that the seasonal variations in the proportions of the different
constituents of the water of the Upper Mississippi River are
quite as frequent and fully as considerable as are the varia-
tions in the composition of the water of the Illinois River.
Comparison of the data for the Mississippi at Quincy
with those for the same stream at Grafton show substantial
similarity of the water at these two points-more than 100
miles apart-both as to the proportions of the different con-
stituents and the variations of the same.
COMPARISON OF THE WATER AT VARIOUS POINTS ALONG
THE ILLINOIS RIVER.-Upon plate VI there are shown the
seasonal variations in the proportions of chlorine in the wat-
ers of the Illinois River at several different points for the
years 1896 to 1900 inclusive. Upon inspection of these curves,
which are representations of all the analyses made in the res-
pective years for the points considered, the great differences
in the content of chlorine between the first half and second
half of the year is manifest, these of course being due to the
greater volume of water flowing during the first half of the year
and the consequent dilution of the sewage, while in the second
half of the year the dilution was small and the proportion of
chlorine naturally much greater.
Comparison of the lines for the year 1900 with those for
the preceding years shows that after the opening of the Chi-
cago Drainage Channel the proportions of chlorine were much
more uniform throughout the year, the reason, of course, be-
ing, that the dilution in the latter half of the year more
94
WATER SUPPLIES OF ILLINOIS.
nearly corresponded to what was formerly the natural dilution
in the earlier part of the year.
Upon Plate V there are shown lines which represent the
proportions of various constituents contained in the waters of
the Illinois River at several different points from Lockport to
Grafton inclusive. For a number of these points the lines
represent the averages for four years analyses preceding the
opening of the Chicago Drainage Channel.
For some of the others, the analyses do not cover so long
a period, but in every case they cover two years or more.
There are also shown in a number of cases the average propor-
tions of the constituents at these same points during the year
1900, that is, the year just after the opening of the Drainage
Channel.
CHLORINE.—The proportion of chlorine in the canal water
at Lockport is seen from the plate to be a little more than
120 parts per million. The considerable drop between Lock-
port and the next point, which is Morris, is due, in small part
of course, to dilution with the waters of the Desplaines River
but is mainly due to dilution with the waters of the Kankakee.
Between Morris and LaSalle the next point, there come
in the discharges from several minor tributaries, but the most
important diluting factor between these points is the Fox
River. From LaSalle to Averyville there is practically no
change in the content of chlorine, for although between
these points various smaller tributaries discharge into the
river, the stream also receives some sewage and waste waters
which are quite highly charged with chlorides and which
consequently, notwithstanding the increase in volume which
occurs, keep up the proportion of chlorine.
Between Averyville and Havana there is a notable dim-
inution in the content of chlorine and from there on to Kamps-
ville and down to the mouth at Grafton a somewhat continuous
decrease is apparent, the proportions at Grafton being 15
parts per million.
The curve for 1900 begins at about the same point but
is intended to show the content of chlorine in the mixture at
Joliet since it is at this point that the different discharges of
Chicago sewage come together. The proportion is but one-

fourth that of the canal at Lockport for the earlier period,
the difference representing approximately the effect of the
dilution produced by the use of the Drainage Channel. From
this point down there is a notable diminution in the propor-
tions of chlorine contained in the water, which in a measure
keeps step with the diminution which formerly occurred, but
is less considerable from point to point, and finally at the
point of discharge into the Mississippi the proportion of
chlorine is slightly more than 13 parts per million, which
shows the effect of the dilution by the use of the Drainage
Channel as it affected the discharge from the Illinois into the
Mississippi during the year 1900.
OXYGEN CONSUMED.--The lines representing the oxygen
consumed, both the total and that by the filtered water, show
marked. diminutions between Lockport and Morris and consid-
erable and somewhat continuous diminution from Morris to
Havana, beyond which point the total oxygen consumed in-
creases slightly so that the proportions required by the water
discharged at Grafton are greater than they were at either
Averyville or Havana, this being in part due to the luxuriant
growth of vegetation in the lower stretches of the river and in
part due to other suspended matters, silt, etc., which during
a portion of the year are more abundant in the lower stretches
of the river than they are farther up.
NITRITES.-Comparisons of the proportions of nitrogen
as nitrites shows that before the opening of the Drainage
Channel there were but extremely small proportions contained
in the water at Lockport, but notably greater proportions at
Morris, the maximum shown being at LaSalle, which argues
for the greater activity of the oxidizing processes near this
point than at points far above or below LaSalle, for while
the proportions of nitrites below this point are always consid-
erable, there is a continuous diminution all the way down to
the mouth of the river at Grafton.
The curve for 1900 shows similar relations between the
different points but a very notably smaller proportion of the
nitrites at points below Morris. It is evident from the curves
however, that the zone in which the greatest activity of the
nitrifying processes is reached, has not been changed in posi-

tion by the opening of the Drainage Channel, that is, it
appears unmistakably from the data of our analyses and is
shown clearly in these curves that the point where the oxida-
tion is most active and thoroughgoing is still between Morris
and LaSalle. The data of Table IX, Page 75, appear to show
that the point is approximately mid-way between these two,
that is, somewhere near Ottawa.
NITRATES. The lines representing the nitrates show a
remarkable increase in the proportions contained as we pro-
ceed from Lockport and Joliet to Morris and so on to LaSalle.
The increase of nitrates between Joliet and Morris is due, of
course, in part to the fact that the waters of the Kankakee
River which unite with those of the Desplaines between these
two points are in certain seasons very highly charged with
nitrates, but much of it undoubtedly is due to the activity of
the nitrifying organisms, which in this stretch of the river
appear to find the conditions of food supply and dilution most
propitious. The greater increase of nitrates between Morris
and LaSalle must be regarded as practically entirely due to
the nitrifying processes which in this stretch of the river com-
plete the destruction, that is, the oxidation, of the organic
matters discharged into the river in the Chicago sewage at
Lockport and Joliet.
From LaSalle to Averyville there occurs a very consider-
erable decrease in the nitrates. This is due not to dilution,
for no considerable dilution occurs between these points, but
to the utilization of nitrates by the vegetation which is ex-
tremely abundant in the broad lake-like stretches of the river
between these points. From Averyville down to the mouth.
of the river there is considerable diminution in the proportions
of the nitrates and this also is due to the cause referred to
.above, namely, the luxuriant vegetation, both that of the river
banks and bed and the floating forms.
The curve for 1900 shows similar sets of conditions al-
though the proportion of nitrates is not so great at Morris as
it was formerly, a fact which is doubtless due to the greater
dilution. At LaSalle, the proportion more nearly approx-
imates those formerly contained, and below this point, although
there takes place a notable diminution in the quantity of
THE ILLINOIS RIVER.
97
nitrates on the way to Averyville and Havana, beyond Hav-
ana they again increase. Below LaSalle there is no point along
the river at which the nitrates are not now present in consid-
erably greater proportions than were found in the river water
before the opening of the Drainage Channel.
With respect
The fact
to these differences in the proportions of nitrates between the
two periods in question, it seems evident that the conclusion
to be drawn must be that, nitrification now takes place at
least as completely, and it would seem far more completely,
than before the opening of the Drainage Channel.
that the proportions of nitrates are less at Havana than at
Kampsville and Grafton, would seem to be due to the fact that
the great masses of filth which are discharged into the stream
in the vicinity of Peoria and Pekin, owe their destruction in
part to the utilization of oxygen from nitrates which are
brought down in abundance by the waters passing Averyville.
FREE AMMONIA. The line representing nitrogen as free
ammonia for the period prior to the opening of the Drainage
Channel shows excessive proportions of this constituent at
Lockport, the diminution on the way to Morris being chiefly
due to dilution, but that between Morris and LaSalle being
mainly due to its oxidation to nitrites and nitrates, to its as-
similation by the vegetation of the river and in part undoubt-
edly to its elimination as free nitrogen gas.
Between LaSalle and lower points upon the river the
diminution proceeds continuously, although free ammonia is
contained in notable quantity in the water finally discharged
into the Mississippi at Grafton.
The line for 1900 shows a much lower content of ammonia
at the point of initial discharge of Chicago sewage, but it
also shows considerable diminution on the way down the river,
although, as is apparent from the plate and also from Table
XV, page 86, and Table XVI, page 89. the proportions con-
tained in the water as it passes Kampsville and is discharged
at Grafton were slightly greater in 1900 than the average for
the preceding years.
ALBUMINOID AMMONIA.-The line representing the nitro-
gen as albuminoid ammonia constitutes for the upper part of
the river a curve quite similar to that just discussed for the
98
WATER SUPPLIES OF ILLINOIS.
free ammonia, but below Averyville there is a slight increase
on the way to Havana, due to the discharge of refuse at Peoria
and Pekin; below this point the quantity does not further dim-
inish but on the other hand very slightly increases. Com-
parison of the line for the total albuminoid ammonia with
that for the albuminoid ammonia derived from substances in
solution, shows that while the latter diminishes markedly be-
tween Havana and Grafton, the total very slightly increases.
TOTAL ORGANIC NITROGEN.-The line representing the
total organic nitrogen shows much the same features as those
just referred to, although the proportions of total organic
nitrogen are somewhat more than twice as much as those of
the albuminoid ammonia.
That the
Comparison of the curves for the period 1897 to 1899 with
the curve for 1900 shows how great an effect the dilution pro-
duced by the opening of the Drainage Channel has had, and
shows that this effect extends to the mouth of the Illinois
River. The fact that the total organic nitrogen and the
nitrogen as albuminoid ammonia do not decrease below Hav-
ana, is undoubtedly due to the presence of the enormous masses
of vegetation in the waters of the lower river.
free ammonia does not decrease below the proportions shown
for Grafton, is doubtless due to its continuous production
through the decomposition of the various organisms constitu-
ting the plankton, which from time to time complete their
life cycles, and the remains of which then enter upon the
universal series of transformations to which all such organic
matters are subject.
COMPARISON OF THE ILLINOIS WITH ITS TRIBUTARies.
Comparison of the detailed data of the analyses of the
water of the Illinois at Averyville and at Grafton with
the data of the analyses of the waters of the tributary
streams, shows that the latter are subject to seasonal vari-
ations which in most respects are quite as great as are
those of the Illinois.
Comparison of the yearly averages, see Table XXII below,
shows that the proportions of organic matters as repre-
sented by oxygen consumed, albuminoid ammonia and
total organic nitrogen, are even more considerable in the
THE ILLINOIS RIVER.
99
waters of the larger tributaries than in the waters of the
Illinois at Grafton, and the general averages for the six
tributaries examined are substantially equal to the aver-
ages for the Illinois for 1900-1-2. Free ammonia and nit-
rites, however, are in general more abundant in the wat-
ers of the Illinois than in the tributary streams, although
three of the latter carry as much or more nitrites than the
Illinois.
Comparisons for the four summer months, for 1899 and for
1900, are shown graphically in Plate XLII.

WATER SUPPLIES OF ILLINOIS.
SUMMARY OF GENERAL CONCLUSIONS.
FIRST. Notwithstanding the discharge of the greater part
of Chicago's sewage into the Desplaines River and thence
into the upper Illinois, and the enormous influx of sewage
and other refuse at Peoria and Pekin, the waters discharged
by the Illinois River into the Mississippi River were, prior to
the opening of the Chicago Main Drainage Channel, in many
respects superior to the waters of the Mississippi itself, and
certainly no more impure than were the waters of its own
larger tributaries.
SECOND. Since the opening of the Chicago Main Drain-
age Channel or Sanitary Canal, although the quantities of
organic matters in the sewage now discharged into the Des-
plaines and Illinois Rivers are 30 per cent. greater than before,
the proportions of organic matters contained in the waters
discharged by the Illinois River into the Mississippi are very
considerably smaller than they were prior to 1900; and that
this decrease of the proportions is not a mere dilution, is
shown by the fact that the actual quantities of organic mat-
ers discharged are now less than they were formerly.*
THIRD. The waters of the Illinois River at Grafton are
practically as well aerated, or rather are as well charged with
dissolved oxygen as are the waters of the Mississippi.
FOURTH. The waters of the Illinois do not mix thor-
oughly with the waters of the Mississippi River, but mainly
pass down near the east bank of the river.

APPENDIX.
THE QUANTITIES OF NITROGEN IN THE WAters of the
ILLINOIS RIVER.--The investigation of the waters of the Illi-
nois River has shown unmistakably that the opening of the
Chicago Main Drainage Channel has brought about a substan-
tial reduction of the proportions of organic matters therein
contained, but the question as to whether this is effected sim-
ply as dilution, or in part through more complete oxidation,
calls for consideration of the actual quantities of the organic
matters contained in these waters.
As measurements of the flows of the Illinois and Michigan
Canal, the Main Drainage Channel, the Desplaines River at
Riverside, and the Desplaines at Joliet are available for the
years 1900 and 1901,* it is possible to calculate the quantities
of organic matters contained in the waters of these various
streams. For Averyville too, discharge measurements made
at Peoria on the behalf of the State Board of Health,† render
it possible, from consideration of the actual flow of water and
the proportional content of the various constituents, to cal-
culate the quantities of organic substances contained in the
water of the Illinois River at this point.
The point to which we have given most attention, how-
ever, is Kampsville, thirty miles above the mouth. Mr. A.
V. Brainerd, Assistant U. S. Engineer, who is in charge of
*These data. for the use of which I am indebted to the Honorable Arthur R.
Reynolds, M. D., Commissioner of Health for Chicago and Director of Streams
Examination for the Sanitary District of Chicago, are not given here in detail but
are represented in the curves of Plates XXXVII and XXXVIII.
+Illinois State Board of Health Report of Sanitary Investigations of the wat-
ers of Illinois River, 1901, Page 179.

APPENDIX-QUANTITIES OF NITROGEN.
the U. S. government work upon the Illinois River, has
kindly furnished us such information concerning the dam
and the stream at Kampsville, as enables us to calculate the
flow for each day throughout the six years of the period we
are considering. The height of water upon the river
gauge at this point is read three times daily and the means
are published in the various reports of the Engineer Corps of
the United States Army; some of the more recent unpub-
lished data have been furnished to us directly by Mr. A. V.
Brainerd.
From these data* the flows per 24 hours have been cal-
culated and the monthly and yearly averages have been com-
puted. The flows for each 24 hours have been calculated by
use of the weir formula, with correction for the submergence
which occurs generally in the spring, but occasionally in
other seasons, and which some times reaches the depth of ten
feet or more. At times when the dam is very deeply sub-
merged, there is also considerable flow over the banks and
through the bottoms around the dam, so that for the short
periods of extremely high water, the flows thus calculated
are undoubtedly much below the truth. Occasionally the
dam is submerged by the backing up† caused by high water in
the Mississippi, though the flow in the Illinois itself at the
time may be small. On the other hand, flows calculated di-
rectly, without allowance for submergence of the weir, are
in all probability considerably too high; but the true flow for
such periods lies somewhere between these limits. It is, of
course, to be noted that the conditions which occasion these
uncertainties exist in general only during a few weeks in the
flood season, that is, in the spring of the year, and that for
most of the year the calculations by the method above given
are correct to within about 10 per cent.
The figures representing the heights of the river gauge
and the flows are not shown in detail in this report, except as
the latter appear in the form of curves upon plates XIX
and XX.
*For supervision of these calculations I am indebted to Professor A. N. Talbot,
head of the department of Municipal and Sanitary Engineering in the University.
+Indeed even a current up stream, i. e., a flow up from the Mississippi to a
point 10 miles above Kampsville or 40 miles above the mouth has been observed.
THE ILLINOIs river.

Upon plate XIX, only the corrected flows for submerged
weir are shown, while upon plate XX there are shown also
the maximum flows for flood periods calculated directly, with-
out allowance for the submergence.
The calculations of the actual quantities of nitrogen in
the organic matters contained in the water at Kampsville
have been made in several different ways: those which appear
in plate XVII representing the total organic nitrogen have
been calculated on the basis of the discharge of water (cor-
rected for submergence of weir) for the day upon which the
sample for analysis was collected.
The lines of this plate show how considerable were the
seasonal variations in the weights of organic nitrogen dis-
charged over the dam at this point during the years 1896-
1900 inclusive.
Com parison of these curves with each other shows that
during the year 1900, that is, the first year after the opening
of the Chicago Main Drainage Channel, the weights of or-
ganic nitrogen carried by the water of the Illinois were gen-
erally less than they were during the preceding years, during
both the high and the low water seasons, except that in 1899,
during the period ranging from the middle of August to the
middle of November, when the flow in the river was extremely
low, the quantities of organic nitrogen were less than in 1900.
Calculations based upon monthly averages, both for the
data of the analyses and for the flow of the river, show sim-
ilar, but of course less irregular variations, throughout the
year.
The data represented by the lines of Plate XXXVI show
that the quantities of organic nitrogen contained in the water
of the Illinois at Kampsville, were in the high water season
not less than six and possibly as much as twelve times as
great as the quantities contained in the water of the Des-
plaines at Joliet, which comprises that of the Upper Des-
plaines, the Chicago Main Drainage Channel or Sanitary
Canal, and the Illinois and Michigan Canal. The lower fig-
ures for Kampsville, which are calculated for submerged
weir, are shown in the plate by the series of small circles, the

higher by the solid line. The differences between the lines
for Averyville and Kampsville indicate the quantities of or-
ganic matters brought into the lower Illinois by tributaries
and the sewage of Peoria, Pekin, etc., which escape oxidation.
Plate XXXV represents similar data for the albuminoid
ammonia.
Plate XXXIV shows that the quantities of nitrogen as
free ammonia, contained in the water of the river at
Kampsville, are very much greater during the high water
period, that is, January, February and March than at any
other time during the year and are several times greater than
the quantities discharged with Chicago sewage into the Des-
plaines at Joliet and Lockport, but that later in the year, from
May to November, the conditions are just reversed, the quanti-
ties contained in the stream at Kampsville and also at Avery-
ville being very much less than the quantities found in the
Sanitary Canal or in the water of the Desplaines at Joliet.
The very large quantities of free ammonia in January and
February are coincident with comparatively low water (See
Plate XX) and with the excessively high proportion of free
ammonia (See Plate XIII) which is characteristic of the Illi-
nois for the extreme cold weather season. The much greater
quantities of free ammonia in March are derived in large part
from the rain and the surface wash.
In Plate XXXIV there are also shown lines representing
the quantities of nitrogen in the form of nitrates. The enor-
mous quantities of nitrates found in the water at Averyville
and Kampsville during March and April, the freshet season,
are in the main derived from the leaching of surface soils by
the run off and the discharges of tile drains.
The decrease at the coming of warmer weather and lower.
water, in May and June, results from the partial cessation of
the leaching, from the partial exhaustion of the supply of nit-
rates in the soil, and from the assimilation of nitrates by the
vegetation, especially that of the plankton which at this season
of the year increases in abundance with very great rapidity.
It has not been practicable for us to give here the numeri
cal data in detail but some of the data for yearly averages ap-
pear in the three following tables.

The evidence seems to show conclusively that since the
opening of the Chicago Main Drainage Channel, there has
taken place not only a considerable diminution of the propor-
tions of the organic matters contained in the waters of the
lower Illinois River, but that a substantial decrease of the
actual quantities of the organic matters contained in these
waters has occurred, and this notwithstanding the fact, which
is shown further along, that the quantities of organic mat-
ters conveyed, in Chicago's sewage, into the upper Illinois are
greater now than they were before the opening of the Main
Drainage Channel.
As it has been shown (see pages 79-82) that the organic
matters contained in the Chicago sewage discharged into the
upper Illinois are practically destroyed or converted into veg-
etable matters by the time the waters reached Peoria, where
another great influx of sewage and other organic wastes
occurs, it will be of interest to compare the condition of the
water at Averyville, just above Peoria, with its condition

THE ILLINOIS RIVER.
ix
The data of this table (XXI) show that the condition of
the water of the Illinois River just above Peoria is very much
better since the opening of the Chicago Main Drainage Chan-
nel and that the natural destruction of the organic matters
discharged into the river in the sewage is, by the time the
water reaches Averyville, far more complete than it was at
this point prior to the year 1900.
The comparison of the data for Kampsville with those
for Averyville shows that for like periods, namely, 1897-8-9
and 1900-1901 (no examinations of the water at Averyville
were made in 1902) the actual weights of nitrites and of free
ammonia carried by the water of the Illinois decreased more
than 40 per cent. during the flow from Averyville to Kamps-
ville.
On the other hand the weights of organic nitrogenous
matters as measured by albuminoid ammonia and the Kjel-
dahl determinations, increased very considerably, though
much less (44.39 per cent. and 62.15 per cent, and 25.03 per
cent and 31.37 per cent respectively) for the period after open-
ing the canal than for the period prior thereto. Oxygen con-
sumed also increased between these two points, 45 per cent.
in the earlier period, 27.68 per cent. in the later.
Inasmuch as the waters of the tributaries of the Illinois
contain organic matters in proportions equal to those of the
Illinois itself, and as enormous quantities of nitrogenous or-
ganic matters are discharged into the Illinois at Peoria and
Pekin, a few miles below Averyville, a considerable increase
in the quantities of nitrogenous organic matters in the water
of the lower Illinois might well be expected, but it is always
to be remembered that the organic matters contained in the
waters of the Illinois below Havana (45 miles below Peoria
and 88 miles above Kampsville) consist of vegetable matters,
chiefly those of the plankton, as is shown both by observation
and by the results of the general investigations recorded in
the body of this report.

APPENDIX-QUANTITIES OF NITROGEN,
THE QUANTITIES OF NITRogenous ORGANIC MATTERS DIS-
CHARGED INTO THE DESPLAINES AND THE ILLINOIS
RIVERS IN CHICAGO SEWAGE.
It is estimated that, of the sewage produced by the popu-
lation of Chicago, about eighty-five per cent. is discharged in-
to the Chicago River and thence goes into the Desplaines and
Illinois Rivers.
The population of Chicago in 1896 was about 1,450,000
and in 1899, about 1,630,000, the mean for the four years
period being 1,542,000. Eighty-five per cent. of this gives
as a mean, a population of about 1,310,700 contributing sew-
age to the river during the period in question.
As it is commonly agreed that the average amount of
feces per day per individual inhabitant is about three ounces,
and that this contains about thirty grams, approximately one
ounce of dry matter, it would appear that, approximately,
forty-one tons of dry matters were discharged into the river
from this source each twenty-four hours. Similar calculation.
concerning the quantity of urine and that of the solid matters
contained therein, upon the basis of a discharge of about forty
ounces of urine per inhabitant per day, would indicate that
from this source there were derived about 86 tons of dry mat-
ers and the total quantity of dry solids from the se sources
discharged into the canal every twenty-four hours, would
consequently, be about 127 tons.
On the average, about eighty-five per cent. of the solid
matters of feces consist of organic matters, the remaining fif-
teen per cent consisting of mineral matters. The total
amount of organic matters from this source then, would be
about 36 tons, which together with the organic matters derived
from the urine, eighty per cent, of the dry matters or 68.8
tons, would equal about 104.8 tons, of which about 34 tons con-
sist of urea.
For a population of 1,310,700 contributing sewage to the
canal, the quantity of nitrogen derived from these sources,
calculated on the basis of the excretion of 14.2 grams of nitro-
gen per inhabitant per day, the figures of Heiden quoted in
Konig, would be 18,612 kilograms or 20.5 tons of nitrogen
THE ILLINOIS RIVER.

per twenty-four hours. Much of the other refuse and wastes
contained in the sewage of the city is nitrogenous but the
quantities of such matters, although certainly very large, are
not known even very approximately.
THE QUANTITIES OF NITROGEN AND ORGANIC MATTERS DIS-
CHARGED BY THE WATERS OF THE ILLINOIS AND MICHI-
GAN CANAL and the SANITARY CANAL.
The analytical data of Table III, page 67, show that the
average proportion of nitrogen as free ammonia for the four
years, 1896-1899, was 13.5 parts per million, and the total or-
ganic nitrogen (by Kjeldahl) 5.3 parts per million.
The average volume pumped into the canal, assumed to
be 36,000 cu. ft. per minute, amounts to 1,623,000 tons of wat-
er or sewage per twenty-four hours, which gives us the factor
1.623 for calculating the total weight of nitrogen carried in the
canal. We thus find that the discharge of nitrogen as am-
monia (13.5 x 1.623) was 21.9 tons per day, and the total
organic nitrogen (5.3 x 1.623) equal to 8.6 tons per day, the
sum 30.5 tons, being fifty per cent more than the 20.5 tons of
nitrogen excreted by the population contributing to the sew-
age of the canal.
The 8.6 tons of total organic nitrogen represent 53.75
tons of protein or nitrogenous organic matters, and the 21.9
tons of nitrogen as free ammonia, if presumed to have been
originally in the form of protein, would represent 136.9 tons
of nitrogenous organic matters. Upon this basis, the total.
quantities of nitrogenous organic matters discharged through
the old canal before the opening of the drainage channel
would amount to 190.7 tons per twenty-four hours, a quantity
very considerably in excess of the nitrogenous matters de-
rived from ordinary sewage calculated upon the above basis.
(page x). A comparatively small part of this difference is
ascribable to the contribution to the sewage of other house-
hold wastes than those contained in the feces and urine, the
major part doubtless being due to the contribution of indus-
*

APPENDIX--QUANTITIES OF NITROgen.
trial wastes, particularly the drainage of the stockyards dis-
trict.
It is to be borne in mind that the thirty-four tons of urea
contained originally in the sewage conveyed to the canal cor-
respond to 15.7 tons of nitrogen, and that the major part of
the 21.9 tons of nitrogen as free ammonia contained in the
canal waters was derived from this source and not from the
more complex nitrogenous organic matters or proteid bodies.
The quantities of organic matters contained in the
waters of the canal, however, were undoubtedly far less than
the total quantities of these matters discharged into the river
by the proportion of the population considered, the difference
being in very large measure due to the putrefactive changes
which begin in the sewers and proceed actively in the river.
The changes which formerly occurred in the waters of
the Chicago River were similar in most respects to those
which take place in the so-called septic tanks, and served to de.
stroy much of the organic matter, some of it being converted
into comparatively inoffensive sludge, and another portion
into gaseous substances which partly escaped into the air,
some of them characterized by disagreeable odors, but others,
as free ammonia, carbon dioxide, nitrogen, hydrogen, etc.,
being inoffensive.
The fact that ordinarily there was but very slight differ-
ence between the quantities of these matters contained in the
water of the canal at Lockport, and the quantities contained
at Bridgeport, would appear to indicate that the putrefactive
or septic changes which went on in the river proceeded ap-
proximately as far as, under these conditions, it was possible
that they should go, and that the matters remaining in the
waters of the canal were in proper condition for the speedy
inception of those changes which mark the next step in the
oxidation of the nitrogenous organic matters and their trans-
formation into innocuous products.
That is to say, the putrefactive changes appear to have
approached completion, and the conditions become such that
no farther changes took place rapidly within the canal itself,
but the next succeeding step was facilitated by dilution of
the sewage and perhaps, also, by the introduction of bacterial

forms of a different character, derived from or contained in
the diluting waters of streams tributary to the Desplaines
and the Illinois, or in the waters of the upper Desplaines
when these waters were sufficient in volume to have marked
diluting effect upon the concentrated but ripened sewage dis-
charged from the canal.
Since the opening of the Sanitary Canal, the larger part
of Chicago's sewage experiences its initial dilution in the Chi-
cago river and passes through the Main Drainage Channel, in
which the mean daily flow for 1900 was 188,340, for 1901
241,323 and for 1902 257,006 cubic feet per minute.
1
The volume of sewage pumped into the Illinois and Mich-
igan Canal, which is now intended to subserve purposes of
navigation only, was reduced from the former average of 36,-
000 cubic feet per minute to 26,700 cubic feet per minute in
1900 and to about 23,000 cubic feet per minute during the seven
months May-November inclusive in 1901, the pumps standing
inactive during the other months of 1901. (See discharge
curves, Plates XXXVII and XXXVIII.) Throughout 1900
and during such part of 1901 as the pumps were in operation,
the Illinois and Michigan Canal discharged' 40 to 45 per cent.
of the nitrogen contained in that part of Chicago's sewage
which is conveyed into the Illinois river, the other 55 to 60
per cent. during this period passing through the Main Drain-
age Channel.
That the disposition, that is the destruction of the or-
ganic matters of the sewage by the natural processes which
are in operation in the waters of the Sanitary Canal, the Des.
plaines River and the Illinois River, are facilitated by the
increased dilution effected by the operation of the Main Drain-
age Channel, has been conclusively demonstrated by the inves-
tigation of the waters of the Illinois River at Averyville and
Kampsville. (See pages 80 and 100 and appendix, v-viii.)
The data in the following tables have been calculated
from the average daily flows for each month in each canal,
and the monthly averages of the analytical data.

=40. tons, the average quantity discharged into the Des-
plaines and thence into the Illinois river, or 31.1 per cent more than the average for
the four preceding years and 26.5 per cent more than in 1899.
The increase in the quantities of nitrogen discharged
into the Desplaines river through the two canals at Lockport
and Joliet, is in part due to the increase in the population
and industries contributing to Chicago's sewage, and in part
due to the fact that a considerable proportion of the contents
of the Chicago river was formerly, from time to time, dis-
charged into the lake, but is now through the operation of
the drainage channel, sent into the Desplaines.
Sewage of PEORIA AND PEKIN.--The sewage of Peoria
includes the sanitary and house sewage of about 55,000 in-
habitants, to which there must be added a portion of the
sewage from the 10,000 inhabitants of Pekin and the 8,000
inhabitants of various other small towns about Peoria. The
substances contained in the house sewage constitute but a
small part of the refuse matters which enter the river at or
near Peoria, for vastly greater quantities of waste organic
matters are derived from the various industries which find
xvi

their center in this vicinity, particularly the breweries, and
the distilleries with adjacent cattle sheds, the glucose fac-
tories, etc.
At Pekin and Peoria from 40,000 to 50,000 cattle are fed
upon distillery slops; the refuse from the stables nearly all
finds its way into the river, although in recent years a portion
of it is filtered and the solid matters used as fertilizers.
The glucose factories use 50,000 or 60,000 bushels of corn
daily, and the distilleries about 22,000 bushels, making a
total of about 70,000 bushels of corn daily.
It is probable that from 7 to 10 per cent. of the weight
of the corn used, including the larger part of the nitrogenous
constituents of the grain, amounting to about 200 tons of dry
waste organic matters from these sources are discharged into
the Illinois River at Peoria and Pekin every 24 hours through-
out the year.
A straw board factory at Peoria runs about 27 tons of
refuse matters into the river daily, of which 19 tons are
organic matters.
It is stated in Konig and elsewhere that the solid matter
in the feces of cattle amount to about thirty-six times the
quantity derived from the same number of human beings.
On this basis, the 40,000 cattle which are fed at Peoria and
Pekin, the excretions from which go into the river, produce
sewage equivalent to that produced by 1,600,000 human
beings, so that the total waste matters introduced into the
river at this point would correspond to the ordinary house
sewage of about 2,000,000 persons.
It would seem that the wastes introduced into the Illinois
at these points are as considerable in amount and as offensive
in character as are those introduced in the sewage of Chicago,
and indeed in times of low water the condition of the Illinois
River between Peoria and Pekin and below Pekin, was often
fully as bad as the condition of the Chicago River in the
times of its most notorious offensiveness.
