Isn't stormwater runoff natural and harmless because it only consists of rainwater?
The rain is not to blame for stormwater runoff problems. In fact, rainfall is completely natural. The problem is the pollution that contaminates runoff during its journey over roads, parking lots and other impervious surfaces. Stormwater can also pick up fertilizers and chemicals from lawns and landscaped areas.
