Elizabeth Mine was a copper mine in Strafford, Vermont, that was abandoned in 1957. It was added to the U.S. Environmental Protection Agency (EPA) Superfund Program’s National Priority List in 2001. Since then, EPA and USGS have cooperated to investigate the nature and extent of contamination from weathering of waste rock rich in metals and sulfides.
