Storm water runoff is the rain or snowmelt that runs off streets, rooftops, parking lots, lawns an other land surfaces. As communities develop, more impervious surfaces are created and less rainfall can soak into the ground.  This increases flooding and stream bank erosion.  Storm water also picks up pollutants as it flows across land surfaces. 

Pollutants include:
▪ Sediment from bare areas like construction sites
▪ Pesticides and fertilizers from lawns, parks, and roadsides
▪ Salt used on roads and driveways
▪ Bacteria and disease causing organisms from pet waste and failing septic systems
▪ Oil and grease from car leaks, gas stations and industrial areas
▪ Toxic chemicals from leaks, spills and auto wear and exhaust.
