Nonpoint Source Program

The Nonpoint Source Program provides funding for projects designed to reduce nonpoint source (NPS) pollution in Delaware. Nonpoint source pollution is pollution that originates from a diffuse source (such as an open field or a road) and is transported to surface or ground waters through leaching or runoff.
