Nonpoint Source Program

The DNREC 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.

The Seventh Annual Recycled Cardboard Boat Regatta that had been scheduled for Saturday, Aug. 6, has been canceled.
