What is nonpoint source pollution?

Nonpoint source pollution is water pollution that is difficult to trace to a specific discharge point. Because it comes from many diverse sources, it is hard to control. Examples of common nonpoint source pollutants include:

  • Fertilizers
  • Litter
  • Oils
  • Pesticides
  • Salts
  • Sediments
  • Trace Metals

They come from farms, yards, roofs, construction sites, automobiles, and streets.
