The United States Environmental Protection Agency (EPA) defines point source pollution as any contaminant that enters the environment from an easily identified and confined place. Nonpoint-source pollution is the opposite of point-source pollution, with pollutants released in a wide area.
.
Moreover, what is an example of nonpoint source pollution?
Nonpoint source pollution can include: Excess fertilizers, herbicides and insecticides from agricultural lands and residential areas. Oil, grease and toxic chemicals from urban runoff and energy production. Sediment from improperly managed construction sites, crop and forest lands, and eroding streambanks.
One may also ask, what does nonpoint mean? Definition of nonpoint. : being a source of pollution (such as runoff from farmland) that is not confined to a single point also : being pollution or a pollutant that does not arise from a single indentifiable source.
Considering this, what are 4 possible sources of point source pollution?
Examples of point sources include sewage treatment plants; oil refineries; paper and pulp mills; chemical, automobile, and electronics manufacturers; and factories. Regulated pollutants from point sources include wastes, soils, rocks, chemicals, bacteria, suspended solids, heavy metals, pesticides, and more.
What is a point source discharge?
The U.S. Environmental Protection Agency (EPA) defines point source pollution as “any single identifiable source of pollution from which pollutants are discharged, such as a pipe, ditch, ship or factory smokestack” (Hill, 1997).

This runoff often contains harmful substances such as toxics, pathogens, excess nutrients and sediments. It is called nonpoint source pollution because it does not come from a single source, or point, such as a sewage treatment plant or an industrial discharge pipe.
