Stormwater runoff occurs when precipitation from rain or snowmelt flows over the ground. Impervious surfaces like driveways, sidewalks, and streets prevent stormwater runoff from naturally soaking into the ground.
Stormwater can pick up debris, chemicals, dirt, and other pollutants and flow into a storm sewer system or directly to a lake, stream, river, wetland, or coastal water. Anything that enters a storm sewer system is discharged untreated into the waterbodies we use for swimming, fishing and providing drinking water.
Here is what you can do to help prevent stormwater runoff pollution:
1. Use fertilizers sparingly and sweep up driveways, sidewalks, and gutters.
2. Never dump anything down a storm drains or in streams.
3. Vegetate bare spots in your yard.
4. Compost your yard waste.
5. Use least toxic pesticides, follow labels, and learn how to prevent pest problems.
6. Direct downspouts away from paved surfaces.
7. Take your car to the car wash instead of washing it in the driveway.
8. Check your car for leaks and recycle your motor oil.
9. Pick up after your pets.
10. Have your septic tank pumped and system inspected regularly.
