What are the effects of nonpoint source pollution?
Nonpoint source pollution is water pollution that is difficult to trace to a specific discharge point. Such pollution comes from many sources such as yards, roofs, construction sites, automobiles, streets, homes and businesses, so it is very hard to control. Stormwater runoff often contains nonpoint source pollutants that flow to our streams, rivers and bays, adversely affecting water quality, plants, fish, animals, and people.
