The Nonpoint Source Grants program, administered by the Illinois Environmental Protection Agency (Illinois EPA) Bureau of Water, provides financial assistance to local governments and organizations for projects that improve water quality by targeting nonpoint source pollution. Nonpoint source pollution arises from diffuse sources such as agricultural or urban runoff and can impair rivers, streams, lakes, and other water bodies across Illinois. The program funds both planning (e.g., watershed-based management plans) and implementation (e.g., best management practices) efforts aimed at reducing, preventing, or eliminating water quality impairments.
