What is Stormwater?
Stormwater runoff occurs when water from rain or melted snow flows over the ground. Surfaces like streets, parking lots, and roofs prevent this water from soaking into the ground naturally. As it flows over the land, stormwater can pick up oil, road salt, and other pollutants before eventually flowing into rivers, lakes, or wetlands.
The United States Environmental Protection Agency (EPA) considers stormwater pollution to be the leading source of water pollution in the country.
