Stormwater Pollution Prevention

Stormwater runoff occurs when precipitation from rain or snowmelt flows over the ground. Impervious surfaces like driveways and streets prevent stormwater from naturally soaking into the ground.

Stormwater can pick up debris, chemicals, dirt and other pollutants and flow directly into a lake, stream, river or wetland. Anything that enters a storm drainage system is discharged untreated into the waterbodies we use for swimming, fishing and providing drinking water.
