United States regulation of point source water pollution information
Overview of the regulation of point source water pollution in the United States of America
The Deer Island Waste Water Treatment Plant, serving the Boston, Massachusetts area, is a typical point source discharger.
Point source water pollution comes from discrete conveyances and alters the chemical, biological, and physical characteristics of water. In the United States, it is largely regulated by the Clean Water Act (CWA).[1] Among other things, the Act requires dischargers to obtain a National Pollutant Discharge Elimination System (NPDES) permit to legally discharge pollutants into a water body. However, point source pollution remains an issue in some water bodies, due to some limitations of the Act. Consequently, other regulatory approaches have emerged, such as water quality trading and voluntary community-level efforts.
