Abandoned Hardrock Mines: Information on Number of

2020-3-5 · Unsecured mine tunnels, toxic waste piles, and other hazards—known as mine features—are found at abandoned hardrock mines across federal and nonfederal lands. The Forest Service, BLM, National Park Service, EPA, and OSMRE—as well as state agencies—administer programs that identify and address hazardous features at abandoned hardrock mines.

Water that is not treated or reused within the mine, e.g., runoff and seepage may reach the surface water and seep into ground water from abandoned mine workings, waste rock, dump piles, tailings and flue dust pile (Street, 1993), and pollute water resources. In surface mining, runoff may get polluted due to the interaction between water and ...
