What is Storm Water Runoff?
Storm water runoff is rain and melting snow that flows off building rooftops, driveways, lawns, streets, parking lots, construction sites, and industrial storage yards. Developed areas are covered by buildings and pavement which do not allow water to soak into the ground. Storm sewers are used to collect large amounts of runoff from streets and parking lots. But where does this water go?
What’s In Storm Water Runoff?
Pollutants on the streets and parking lots get washed away with the storm water runoff into waterways. Here are some of the types of pollutants in storm water runoff.
- Oil and grease
- Sediment from construction sites and urban runoff
- Metal flakes from rusting vehicles and brakes
- Road salt
- Lawn pesticides
- Agricultural herbicides
- Heavy metals from roof shingles
- Pet waste
- Grass clippings
- Nutrients such as phosphorus and nitrogen
- Other chemicals
- Illicit discharges such as paints, cleaning solution products and used motor oil.
Storm water is not clean and it can pollute our streams and lakes. Contaminated storm water is the largest contributor of pollutants to Wisconsin’s urban waters today. These types of pollutants can harm fish and wildlife populations, kill native vegetation, foul drinking water supplies, and make recreational areas unsafe and unpleasant.
