In 1983, the U.S. Environmental Protection Agency (EPA) established a 21 square-mile Superfund cleanup site surrounding the defunct Bunker Hill Mine and ore-processing complex in Kellogg, Idaho. The State of Idaho, other Federal agencies, and the mining industry also are conducting site-specific sediment removal, reclamation, and stream-channel rehabilitation.
In 2002, the EPA and Idaho Water Science Center established a Basin Environmental Monitoring Program (BEMP). The BEMP provides long-term data that helps the EPA and other decision makers evaluate and adjust the ongoing cleanup efforts. With EPA funding, the Idaho Water Science Center collects specific types of water data at 16 monitoring sites located along more than 160 river miles. Sediment and biological resource data is also collected.
