Stormwater pollution comes from many sources. As rainwater and other runoff flows across the ground, they pick up harmful contaminants like fertilizers, pesticides and dirt. When the rainwater hits our streets, the water mixes with waste oil, automotive fluids and plant debris. Unlike the wastewater we put down our sinks and toilets, stormwater flows to our waterways untreated. This contaminates the water and can harm wildlife in our watershed.

Stormwater pollution is considered the most significant source of water pollution in our country. Past water pollution control efforts were directed at industrial sources and good progress has been made. Now, non-industrial activities impact water quality more than industrial operations.
