What is polluted stormwater?
A. – Polluted stormwater is rainwater runoff that carries pollutants into the storm drain system. Stormwater pollution is caused in two ways: directly, when individuals pour pollutants into storm drains; and indirectly, when water flowing over streets, parking lots and yards carries contaminants such as motor oil and pesticides, into the storm drain systems. Because it can originate from so many sources, stormwater pollution is very difficult to monitor and control. As development and population increases, so does the volume of contaminants entering the storm drain system.
