Estimates of discharge from wastewater treatment plants for 1,518 U.S. Geological Survey study watersheds, 1978 through 2012

공공데이터포털

This product consists of a table of annual discharge estimates in millions of gallons per day from wastewater treatment plants (WWTPs) for 1,518 watersheds in the conterminous United States. The data are based on information extracted from the U.S. Environmental Protection Agency’s Clean Watersheds Needs Survey. The data are for 13 time periods, beginning in 1978 and ending in 2012. Total nitrogen and phosphorus loads from WWTPs per watershed for each year are also provided, based on previously published data (Falcone, 2017).
