It includes an area of about 112 square miles in the northern part of Plymouth County, Massachusetts. This report presents basic data collected as part of an investigation of the geology and ground-water resources of the Brockton-Pembroke area, Massachusetts by the U. S. Geological Survey in cooperation with the Massachusetts Water Resources Commission. These data have been prepared for release in order to make available to the public basic ground-water data that will be useful in the planning of water-resources development. Most of the data contained in this report were collected by Richard G. Petersen and Charles E. Shaw, Jr. during the period 1957-60. Richard J. Hecht and Russell P. Cook assisted with the data collection. Stream-flow measurements in table 7 were made by Donald F. Farrell. The data include records of 364 wells and test holes (table 2); logs of 184 wells and test holes (table 3 ); chemical analyses of 11 water samples (table 4); measurements of water levels in 26 wells (table 5 ); measurements of water levels and water temperatures in 5 ponds (table 6); and measurements of discharge in 5 streams (table 7)* Table 1 is intended to be an aid in determining the general characteristics and relative excellence as aquifers of the water-bearing units penetrated by the wells and test holes. WELL-NUMBERING AND LOCATION SYSTEMS In Massachusetts each well is designated by a symbol whose first term is the name of the town or city in which the well is located and whose second term is a number that is assigned in the order in which * the well was inventoried within the town or city. A separate series of numbers beginning with 1 is used within each town or city. In the tables the name of the town and the number are given, but on the map (fig. l) only the number appears beside the symbol of the well. For ease in locating wells and test holes on the map, a location system based on the jjr -minute topographic quadrangles in New England is used. In this system each T^-minute quadrangle is designated by a capital letter and a number beginning with A1 for the Glenville quadrangle, Connecticut. From here the quadrangles are lettered from west to east and numbered from south to north. Each T^niinute quadrangle is subdivided into nine 2-^-minute rectangles, and each 2-1-minute rectangle is subdivided into nine 50-second rectangles, as shown on the sketch (fig. 2). The location designation for each well and test hole is listed in table 2. On the well-location map (fig. l), the quadrangle designators are indicated on the margins and the 2-g--minute rectangles are bounded by the lines of latitude and longitude, but the 50-second rectangles are not shown.
