What is stormwater runoff pollution?

Every day, trash, oil, sediment, chemicals, bacteria, and other pollutants collect on our rooftops, roads, parking lots, and driveways. When it rains, the pollutants travel over these surfaces, flow into the storm drain system, and in great volume end up in our creeks, rivers, lakes, and streams. Learn about some common sources and concerns for each type of pollutant.
