Non-Point Source (NPS) pollution does not come from a single point, such as a sewage treatment plant or an industrial discharge pipe. NPS pollution comes from the build-up of pollutants that is picked-up and transported by stormwater to rivers, creeks, and other water bodies.
Examples of NPS Pollutants
Motor oil and grease from automobiles
Fertilizer and pesticides from lawns or farms
Sediment from erosion of unprotected lands and/or construction sites
