Pandemic spotlight on urban water quality 2020-05-06 .txt text/plain 682 40 43 Surface water improvements associated with the COVID-19 economic slowdown illustrate environmental resiliency and societal control over urban water quality. Under an economic slowdown scenario, headwaters hundreds of kilometers away from urban areas will experience reduced deposition from nonpoint sources of pollution (regionally produced nitrogen dioxide, sulfur dioxide, ammonia, and other gaseous pollutants). For example, given the reduction in nitrogen dioxide concentrations observed over Eastern China, Europe, the Northeastern United States, and India ( Fig. 1) , this is where urban surface water quality may start showing signs of temporary recovery. Given the frequent occurrence of urban water crises, it is critical to document how COVID-19 pandemic response management affects natural processes and surface water quality in the short term. The current challenge, though, is that economic sectors and industries that contribute to pollution (e.g., energy, consumer, pharmaceutical, and other industries) receive little incentive to promote urban water quality beyond what the law requires. ./cache/cord-312528-erl8jftp.txt ./txt/cord-312528-erl8jftp.txt
