Point source water pollution is largely regulated through the Clean Water Act, which gives the EPA the authority to set limits on the acceptable amount of pollutants that can be discharged into waters of the United States. The 1972 law also created federal authority for a permit system—NPDES—to enforce the pollution standards.
Technically, the name of the law is the Federal Water Pollution Control Act. [3] ... (NPDES), a permit system for regulating point sources of pollution. [15]
Point sources could include leaking septic tanks, oil spills, dumping of waste, or wastewater treatment facilities. [17] In order to prevent point source pollution from occurring, the Clean Water Act regulates what can be discharged into a water body by requiring each facility to obtain a National Pollutant Discharge Elimination System (NPDES ...
A point source of pollution is a single identifiable source of air, water, thermal, noise or light pollution. A point source has negligible extent, distinguishing it from other pollution source geometrics (such as nonpoint source or area source). The sources are called point sources because in mathematical modeling, they can be approximated as ...
Water pollution also reduces the ecosystem services such as drinking water provided by the water resource. Sources of water pollution are either point sources or non-point sources. [4] Point sources have one identifiable cause, such as a storm drain, a wastewater treatment plant or an oil spill. Non-point sources are more diffuse.
The definition of NPS water pollution is open to interpretation. However, federal regulation under the CWA provides a specific legal definition for the term. A "nonpoint source" is defined as any source of water pollution that is not a "point source" as defined in CWA section 502(14). [26]
