||As part of the Superfund Innovative Technology Evaluation (SITE) program, U.S. Environmental Protection Agency (EPA) National Risk Management Research Laboratory (NRMRL), in cooperation with EPA Region IX, the state of California, and the Atlantic Richfield Company (ARCO) evaluated lime treatment of acid mine drainage (AMD) and acid rock drainage (ARD) at the Leviathan Mine Superfund site located in Alpine County, California. EPA evaluated two lime treatment systems in operation at the mine in 2002 and 2003: an active lime treatment system operated in biphasic and monophasic modes, and a semi-passive alkaline lagoon treatment system. The treatment systems utilize the same chemistry to treat AMD generated within the mine workings and ARD generated from surface seeps within waste rock; the addition of lime to neutralize acidity and remove toxic levels of metals by precipitation. The primary metals of concern in the AMD and ARD include aluminum, arsenic, copper, iron, and nickel; secondary water quality indicator metals include cadmium, chromium, lead, selenium, and zinc.
