How is construction runoff harmful?

Q.  How is construction runoff harmful?

A.  Sediment laden stormwater runoff from active construction sites is one of the nations leading water resource pollutants.  Sediment and other pollutants, such as cement, paint, fuel, and oil, from construction sites can cause physical, chemical, and biological harm to our water resources.  Polluted storm water runoff from construction sites can flow into the storm drain system and eventually discharge into our local rivers, lakes, wetlands, and streams.
