IRON MOUNTAIN MINE
Superfund Site Profile
The 4,400-acre Iron Mountain Mine site was periodically mined for iron, silver, gold, copper, zinc and pyrite. Though mining operations were discontinued, underground mine workings, waste rock dumps, piles of mine tailings and an open mine pit remain at the site. Much of the acidic mine drainage ultimately is channeled into the Spring Creek Reservoir. About 70,000 people use surface water within three miles as their source of drinking water. Site investigations and cleanup are ongoing.
