As part of the Superfund Innovative Technology Evaluation (SITE) program, an evaluation of the compost-free bioreactor treatment of acid rock drainage (ARD) from the Aspen Seep was conducted at the Leviathan Mine Superfund site located in a remote, high altitude area of Alpine County, California. The evaluation was performed by U.S. Environmental Protection Agency (EPA) National Risk Management Research Laboratory (NRMRL), in cooperation with EPA Region IX, the state of California, and Atlantic Richfield Company (ARCO), and the University of Nevada-Reno (UNR). The primary target metals of concern in the ARD include aluminum, copper, iron, and nickel; secondary target metals include selenium and zinc.
