        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.
