Point source pollution is typified by the discharge of sewage or chemicals from a facility that has an identified point of release. For example, water discharging from an industrial plant or a waste water treatment plant.

What You'll Learn
Sewage and wastewater treatment
Water quality is influenced by direct inputs, such as from a factory or sewage treatment plant, so-called “point source pollution”. Point sources come from discrete pipes flowing into a river for example. Non-point sources are more diffuse sources that don't come from one single pipe or outlet. Point sources are for example, water discharging from an industrial plant of some kind or a waste water treatment plant.
The main point source of pollution to water is from sewage and waste water treatment. When attempting to evaluate the magnitude and extent of pollution on water resources, it is critical to distinguish between point and nonpoint sources of pollution. Point source pollution is typified by the discharge of sewage or chemicals (i.e., in either gas, liquid, or solid form) from a facility that has an identified point of release. For example, chemicals or biological wastes are discharged into surface water (rivers, lakes, bays, and oceans) from industrial wastewater and sewage outfalls.
Water quality is influenced by direct inputs, such as from a factory or sewage treatment plant, so-called “point source pollution”. Water quality is also influenced by pollution from widespread sources, such as nutrients and pesticides from farming activities and pollutants released by industry into the air which then fall back to land and sea, so-called “diffuse pollution”. The main point source of pollution to water is from sewage and waste water treatment, while for diffuse pollution, main sources are from farming and fossil fuel power plants (via the air).
Non-point sources of pollution are much harder to identify and correct because they may be intermittent or from many sources at the same time. Most non-point source pollution is caused by either sediment or nutrients. Sediment could include soil particles that have eroded from construction sites, stream banks, cropland or residential renovation. Sediment can be a point or non-point type of pollution. Sediment turns the water cloudy or “turbid.” This makes it difficult for fish to see and feed. It can damage gills, which makes it harder for fish to breathe. Soil particles can also cover spawning habitats limiting reproduction of fish populations.
