Point source. A specific site from which waste or polluted water is discharged into a water body, the source of which is identified. See also: non-point source.

poison (in toxicology)

Point Source Contamination: water contamination from specific sources such as leaking underground storage tanks, landfills, industrial waste discharge points, or chemical mixing sites.

Point Source - Pollutants which are put into the atmosphere by stationary objects, such as refineries, power plants, mills, and the like. In Texas any source that emits more than one ton in a calendar year is considered a point source.

Point Source - A stationary location or fixed facility from which pollutants are discharged; any single identifiable source of pollution, e.g., a pipe, ditch, ship, ore pit, factory smokestack.

Non-Point Sources: Diffuse pollution sources, i.e., without a single point of origin or not introduced into a receiving stream from a specific outlet. The pollutants are generally carried off the land by storm water.

Nonpoint Source Pollution - Nonpoint source pollution (or NPS pollution) is a type of water pollution that does not originate from a specific place but instead from a variety of diffuse sources.

The Act made it unlawful for any person to discharge any pollutant from a point source into navigable waters, unless a permit was obtained under its provisions.

In the past, this type of large dose, "point source pollution" was common in certain parts of the country. With new technologies and environmental legislation, this type of destruction no longer takes place.

Significant Violations: Violations by point source dischargers of sufficient magnitude or duration to be a regulatory priority.
Silt: Sedimentary materials composed of fine or intermediate-sized mineral particles.

vegetative controls Nonpoint source polltion control practices that involve plants (vegetative cover) to reduce erosion and minimize the runoff of pollutants.

A key provision is that “any person responsible for the discharge of a pollutant or pollutants into any waters of the United States from any point source must apply for and obtain a permit.
