Non-Point Source Pollution

What is Non-Point Source (NPS) Pollution?
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
  • Organic wastes, from manure and sewage
  • Pathogens, such as bacteria and viruses
