What is nonpoint source pollution?
NonPoint Source Pollution (NPS) is pollution that comes from diffuse sources, i.e. sources that are spread out and widely scattered. This means that the pollutant is coming from many locations, in small amounts. NPS is usually associated with stormwater because the runoff generated during rain events can carry pollutants from the ground to the stream.
