What kind of pollution is in stormwater runoff?
The pollution depends on where and what the rainfall runoff is draining from. Nearly all runoff contains silt and soil as a result of erosion. Runoff from agricultural lands and our lawns often contain fertilizer and herbicides. Runoff from streets and highways may contain oil and grease plus heavy metals such as lead from gasoline exhaust emissions and selenium from tires.
