While performing research into premature pipe corrosion for the District of Columbia Water and Sewer Authority (WASA) in 2001, Marc Edwards, an expert in plumbing corrosion, discovered lead levels in the drinking water of Washington, D.C., at least 83 times higher than the accepted safe limit.
The Washington Suburban Sanitary Commission (WSSC Water) is a bi-county political subdivision of the State of Maryland [2] that provides safe drinking water and wastewater treatment for Montgomery and Prince George's Counties in Maryland except for a few cities in both counties that continue to operate their own water facilities.
The utility also provides wholesale wastewater treatment services to several adjoining municipalities in Maryland and Virginia, and maintains more than 9,000 public fire hydrants in Washington, D.C. DC Water was founded in 1996 when the city government and the U.S. federal government established it as an independent authority of the city's ...
An indirect discharger is one that sends its wastewater into a city sewer system, which carries it to the municipal sewage treatment plant or publicly owned treatment works (POTW). [37] At the POTW, harmful pollutants in domestic sewage , called conventional pollutants , are removed from the sewage and then the treated effluent is discharged ...
Permits typically require reporting of wastewater flow and the results of one or more chemical tests corresponding to the effluent limitations. Typical monitoring parameters include pH, biochemical oxygen demand (BOD), total suspended solids (TSS), nutrients (nitrates and phosphorus), various toxic pollutants, temperature, etc.
Blue Plains Advanced Wastewater Treatment Plant in Washington, D.C., is the largest advanced wastewater treatment plant in the world. [1] The facility is operated by the District of Columbia Water and Sewer Authority (DC Water). The plant opened in 1937 as a primary treatment facility, and advanced treatment capacity was added in the 1970s and ...
Topsoil runoff from farm, central Iowa (2011). Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and manufacturing industries—although laws and regulations introduced in the late 20th century have improved water quality in many water bodies.

PG&E used this chemical to deter corrosion in their cooling towers. The use of this chemical in cooling towers lead to a wastewater leakage into unlined ponds at their cooling tower sites. This, in turn, turned into groundwater contamination which adversely affected the town of Hinkley. The contamination resulted in a $333 million settlement in ...
