Stormwater Basics

We need your help! Stormwater pollution can not be ignored and can only be prevented with all of us working together. Learn the stormwater basics and get involved. Our water, our health, and our ecosystems are at stake!



Stormwater pollution is rapidly growing in importance as a national environmental issue. Stormwater pollution occurs when rain or snow melt flows over streets and picks up trash, oil, dirt, and other pollutants as it travels. These pollutants are then carried to the storm drainage system, which drains directly into our local creeks and streams, untreated.

Why Is This Important?

Because, as stated by the EPA, stormwater pollution is the #1 source of water pollution in the country. Stormwater—it’s a big deal! As communities become increasingly developed with more roads, parking lots, cars and homes, increased urbanization and increased impervious surfaces, directly impact our water. The creation of impervious surfaces that accompanies urbanization profoundly affects how water moves above and below ground during storms. These impervious surfaces impact the quality of stormwater, and the condition of our creeks.

Common Pollutants

Motor oil, sediment, yard waste/leaves, biodegradable materials, and paint are common pollutants that should never be put down the storm drain. These materials will travel directly into streams and creeks UNTREATED, polluting water and natural habitats.
