Nonpoint source pollution

From Wikipedia, the free encyclopedia

Nonpoint source pollution (NPS) does not come from a single source like point source pollution. It comes from many unidentifiable sources with no specific solution to rectify the problem, making it difficult to regulate. An example of NPS pollution would be urban runnoff of items like oil, fertilizers, and lawn chemicals. As rainfall or snowmelt moves over and through the ground, it picks up and carries away natural and human-made pollutants. These pollutants are eventually deposited into natural bodies of water, such as lakes, rivers, wetlands, coastal waters, and underground sources of drinking water.
