Stormwater Pollution: What Is It? and What Can I Do About It?

In urban areas, where there are more parking lots, sidewalks, paved streets and rooftops, less rainfall can soak into the ground. The runoff is carried by curbs or gutters into storm drains or spillways. Storm drains are separate from the sanitary sewer and DO NOT lead to a treatment plant. The stormwater runoff is ultimately deposited in our washes, rivers, or lakes without being treated.
