Permeable Pavement and Reducing Water Runoff

Paved parking lots and driveways often create an easy pathway for pollutants to reach underground water sources and change the natural flow of water back into the ground. Today, EPA announced a study that will investigate ways to reduce pollution that can run off paved surfaces and improve how water filters back into the ground.
