Frequently Asked Questions (FAQ)

Question:
What is "Nonpoint Source" Pollution?

ANSWER:
The regulatory definition states that nonpoint sources are “sources not defined by statute as point sources; include return flow from irrigated agriculture, other agricultural and silvicultural runoff and infiltration, urban runoff from small or unsewered urban areas, flow from abandoned mines, and hydrologic modification.” Examples of pollution associated with agriculture and forestry are sediments, nutrients, and pesticides.
