Pollution in Stormwater Runoff

The federal government has determined that stormwater runoff is the leading cause of water pollution in the nation. When it rains, stormwater collects many types of hazardous materials that flow directly into area lakes and streams. Stormwater is not treated. Oils, chemicals, fertilizers, litter and waste in stormwater can cause major problems in waterways. The effects may vary; however, research has shown that pollution affects drinking water supplies, recreation, fisheries and wildlife.

Stormwater pollution results from a wide variety of human activities. Each of us can contribute to the problem without even realizing it.

You can help reduce pollution by remembering to keep potential pollutants away from storm drains. Never throw or dump anything down a storm drain. Not only can this contaminate local waters, but it can also contribute to flooding by blocking drains, inlets and ditches.
