Stormwater is water that originates during precipitation events. Stormwater that does not soak into the ground becomes surface runoff, which either flows directly into surface waterways or is channeled into storm sewers, which eventually discharge to surface waters.
10 Things You Can Do to Prevent Stormwater Runoff Pollution

Compost your yard waste
Avoid pesticides; learn about Integrated Pest Management (IPM)
Direct downspouts away from paved surfaces
Take your car to the car wash instead of washing it in the driveway
Check car for leaks, and recycle motor oil
Pick up after your pet
