Effluent Guidelines currently control pollution at approximately 40,000 facilities that discharge directly to the nation's waters, 129,000 facilities that discharge to POTWs, and construction sites. Effluent Guidelines are implemented in water discharge permits issued to facilities through the National Pollutant Discharge Elimination System ...
Pollution of the river had become prevalent in the early 1800s [7] as contaminants from municipal and industrial discharges, bank erosion, commercial/residential development, atmospheric deposition, hazardous waste disposal sites, urban storm water runoff, combined sewer overflows (CSOs) and wastewater treatment plant bypasses were discharged ...
A Discharge Monitoring Report (DMR) is a United States regulatory term for a periodic water pollution report prepared by industries, municipalities and other facilities discharging to surface waters. [ 1 ] : 8–14 The facilities collect wastewater samples, conduct chemical and/or biological tests of the samples, and submit reports to a state ...
Municipal and industrial permittees are required to regularly collect and analyze wastewater samples, and submit Discharge Monitoring Reports to a state agency or EPA. [17] Amendments in 1977 required stricter regulation of toxic pollutants. [18] In 1987 Congress expanded NPDES permit coverage to include municipal and industrial stormwater ...
Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges.

The basic national standard for U.S. municipal treatment plants is the Secondary Treatment Regulation. [2] Most plants in the U.S. must meet this secondary treatment standard. The permit authority (state agency or EPA) can compel a POTW to meet a higher standard, if there are applicable water quality standards for the receiving water body.
The industrial and municipal standards are implemented in discharge permits issued by state agencies and EPA, under the National Pollutant Discharge Elimination System (NPDES). [26] [27] All point sources of pollution obtain permits prior to discharge. Nonpoint sources are not subject to the permit program. [28
