The dam has been subjected to severe erosion and water emanates from the dam in several places. The face of the dam is deeply incised and erodes directly into a creek. The creek, the Ore Knob Branch, is piped underneath the tailings impoundment through a 24 inch pipe that exits the bottom of the dam face.
Mining produces mainly tailings (the waste materials left after the valuable ore is separated out) and overburden (the waste materials removed to reach the ore). During the mining process, water within and around the mine is usually contaminated, so treating the mine water before it is discharged back into the environment is a major issue [2].
