What is Stormwater Runoff Pollution?

Stormwater runoff pollution is often called non-point source pollution. It is basically rain water that becomes polluted once earthbound, and the pollution occurs from many sources. Sources of stormwater pollution are driveways, streets, parking lots, construction sites, agricultural fields, lawns, pet wastes, failing sewer systems, leaking septic tanks, and illicit discharges such as dumping waste motor oil. Pollutants of concern include but are not limited to oils, grease, sediment, fertilizers, pesticides, herbicides, bacteria, debris and litter, etc.

Stormwater runoff can wash these pollutants into local streams and drainage basins. Please remember, stormwater runoff does not flow to a treatment plant; it flows directly into our streams and lakes. Stormwater runoff from the Town of Sandown ultimately reaches the waters you in which you fish, swim and recreate so it is imperative to implement best management practices to better manage stormwater runoff.
