Stormwater Management

Stormwater is a leading source of water pollution in the U.S. Stormwater runoff is created when rain or snow melts on surfaces that cannot or do not absorb it due to falling on streets, sidewalks, or lawns with compacted soil. As the precipitation runs over these surfaces, it accumulates pollutants such as debris, sediment, and chemicals. If not managed correctly, runoff can compromise the quality of water in lakes, rivers, and coastal areas.

Runoff from construction sites can be especially harmful. Stormwater pollution poses such a threat that the U.S. Environmental Protection Agency instituted standards for stormwater management in areas that are established and developed.
