ECOLOGY FOR YOU

Stormwater is rain and snow melt that runs off surfaces such as rooftops, paved streets, highways, and parking lots. The volume of water running off the landscape and the mass loads of pollutants that water carries can be significantly higher than natural conditions.
Polluted stormwater runoff contributes to issues with human health, degraded quality for drinking water and in streams, rivers, lakes and the Puget Sound. Low water quality in the natural environment impairs habitat and puts Washington fish and wildlife at risk. Learn more in the stormwater overview.
