Description: There are five acid discharges flowing from abandoned deep mine openings and large, denuded seepage areas. Approximately two acres of upland forest has been destroyed by mine drainage. This site has the highest levels of aluminum and acid of any discharges in the watershed. The treatment system includes two initial sediment basins, two vertical flow treatment ponds and a large final settling basin. This project took two years to complete and required additional components such as a High Density Poly Ethylene (HDPE) liner (to prevent the potential of leaks) and chain link fence as a safety precaution.
