Water Pollution caused by Runoff, Erosion and Sedimentation

Earth disturbance, such as construction activities, loosens the earth. During periods of rain, the loose dirt and sediments may wash off the land and into streams and rivers. This runoff is water pollution caused by erosion and sedimentation. The EPA has published a PDF handout - A Citizen's Guide to Understanding Stormwater - that can assist in learning more about stormwater.

To learn more about prevention techniques and requirements, look at the websites below.

In Pennsylvania, the state has generally delegated the implementation of the erosion and sedimentation program to the County Conservation Districts. The Pennsylvania Association of Conservation Districts provides general information about conservation districts on their website.
