What is Non-Point Source Stormwater Pollution?

As stormwater flows over parking lots, streets, driveways, lawns, and sidewalks, it picks up debris, chemicals, dirt, and other NPS pollutants.

Where does stormwater and NPS pollution go?

Stormwater and NPS pollution flow into storm sewers, streams or directly off of the land and into the Fox River. Polluted runoff is the nation’s greatest threat to clean water.

How can you help reduce NPS pollution and protect the Fox River?

  1. Plant a Rain Garden: Rain Gardens are landscaped depressions designed to capture and treat stormwater.
  2. Install Rain Barrels: Rain barrels capture and store rain water from rooftops. The water that is collected helps reduce stormwater runoff and therefore decreases NPS pollution.
