What is Stormwater runoff? Stormwater runoff occurs when precipitation from rain flows over the ground. Impervious surfaces like driveways, sidewalks, and streets prevent stormwater from naturally soaking into the ground.
Why is Stormwater runoff a problem? Stormwater can pick up debris, chemicals, dirt, and other pollutants and flow into a storm sewer system that leads directly to local waterways including the Vermilion River. Anything that enters a storm water system is discharged untreated into the waterways we could use for water activities including boating, fishing, and swimming.
The effects of pollution - Polluted Stormwater runoff can have many adverse effects on plants, fish, animals and people.
