Understanding Point Source Water Pollution: Causes And Solutions

Point source pollution is a term used to describe pollution that originates from a well-defined source over a discrete area. 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.” Examples of point source pollution include sewage pipes, smokestacks, heated water and large farms that raise livestock.

Point source pollution is defined by the U.S. Environmental Protection Agency (EPA) as “any single identifiable source of pollution from which pollutants are discharged, such as a pipe, ditch, ship or factory smokestack.”

Point source pollution originates from a well-defined source over a discrete area. Examples of point source pollution include discharge outlets like a sewage pipe or a smokestack. In contrast, nonpoint source pollution originates over a broad area.

Point source pollution can result in water pollution and unsafe drinking water. Some of the chemicals discharged by point sources are harmless, but others are toxic to people and wildlife. Whether a discharged chemical is harmful to the aquatic environment depends on a number of factors, including the type of chemical, its concentration, the timing of its release, weather conditions, and the organisms living in the area.

The seemingly innocuous release of heated water is also a common form of point source pollution. Hot water released into a stream or pond can raise the ambient temperature of the water body. The change of temperature, in turn, can make the water unsuitable for some of the forms of life ordinarily inhabiting the area. Microscopic flora and fauna, in particular, can be unusually sensitive to changes in ambient temperature.

Many types of facilities release heated water, and power plants typically use enormous amounts of fresh water to cool power-generating equipment. The cooling water becomes heated. Even if it is passed through cooling towers to dissipate some of the heat, the eventual point source discharge is still generally warmer than the receiving waters.

Discharge outlets like sewage pipes or smokestacks are point sources

Point source pollution is a phrase used by the U.S. Environmental Protection Agency, state environmental agencies, other environmental regulators and international agencies to refer to pollution that originates from a well-defined source over a discrete area. Point source examples include discharge outlets like a sewage pipe or a smokestack. In contrast, nonpoint source pollution originates over a broad area. A parking lot or farm field surface runoff is an example of nonpoint source pollution.

Factories and sewage treatment plants are two common types of point sources. Factories, including oil refineries, pulp and paper mills, and chemical, electronics and automobile manufacturers, typically discharge one or more pollutants in their discharged waters (called effluents). Unregulated discharges from point sources can result in water pollution and unsafe drinking water, and can restrict activities like fishing and swimming.

Large farms that raise livestock, such as cows, pigs and chickens, are other sources of point source pollution. These types of farms are known as concentrated animal feeding operations (CAFOs). The seemingly innocuous release of heated water is also a common form of point source pollution. Hot water released into a stream or pond can raise the ambient temperature of the water body.
