The Clean Water Act has made great strides in reducing point source water pollution, but this effect is overshadowed by the fact that nonpoint source pollution, which is not subject to regulation under the Act, has correspondingly increased. [41] One of the solutions to address this imbalance is point/nonpoint source trading of pollutants.
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 ...
Water pollution point sources Air pollution point sources. 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).
Nonpoint sources are the most significant single source of water pollution in the United States, accounting for almost half of all water pollution, [1] and agricultural runoff is the single largest source of nonpoint source water pollution. [2] This water pollution has a number of detrimental effects on human health and the environment.
The U.S. Clean Water Act (CWA) defines point source for regulatory enforcement purposes (see United States regulation of point source water pollution). [54] The CWA definition of point source was amended in 1987 to include municipal storm sewer systems, as well as industrial storm water, such as from construction sites. [55]
In the settlement, FDEP agreed to draft language for a Clean Water Act permit that will require the agency to monitor and publicly report on potential sources of pollution at Piney Point.
The first FWPCA was enacted in 1948, but took on its modern form when completely rewritten in 1972 in an act entitled the Federal Water Pollution Control Act Amendments of 1972. [4] [1] Major changes have subsequently been introduced via amendatory legislation including the Clean Water Act of 1977 [5] and the Water Quality Act (WQA) of 1987. [6]
