Acid Mine Drainage Remediation

In this video, an environmental technologist visits an abandoned coal mine in Kentucky to talk about how a remediation system (a series of settling ponds and treatment cells) is neutralizing the acid drainage from the mine and preventing damage to a creek downstream. He shows the path of the acid drainage as it flows down a hillside from the mine into a settling basin and on to treatment cells where limestone is used to raise the water's pH. At a higher pH, iron and other minerals drop out of solution, which means that these harmful precipitates stay in the settling basins rather than flowing into the creek.

This video examines the purpose and anatomy of a well and how it is drilled. Through a diagram of Louisville Water Company's riverbank filtration system, you see how water moves through the aquifer to the well and from the well to the tunnel via "well screens" that filter out particulates and channel the water to the tunnel. Finally the water is pumped to the water company where it chemically treated to produce safe drinking water.
