This report summarizes the results of Mine Waste Technology Program (MWTP) Activity III, Project 39, Permeable Treatment Wall Effectiveness Monitoring Project, implemented and funded by the U.S. Environmental Protection Agency (EPA) and jointly administered by EPA and the U.S. Department of Energy (DOE). This project addressed EPA's technical issue of Mobile Toxic Constituents-- Water through a field demonstration of a water treatment process based on the use of Apatite II treatment medium at a remote, inactive underground mine. This project was undertaken to demonstrate the effectiveness of Apatite II (cleaned fishbone) to treat metal-laden water flowing from an abandoned mine. The Nevada Stewart Mine (NSM), located in the Coeur d'Alene Basin near Pinehurst, Idaho, was selected as the site for the field demonstration. The NSM is part of the Bunker Hill Mining and Metallurgical Complex, which was placed on the National Priorities List (NPL) for Superfund cleanup of heavy metals, mainly zinc, lead, and cadmium. To determine the effectiveness of the apatite material, a permeable treatment wall system (also referred to as the ApatiteTM II Treatment System (ATS)) was constructed by MSE Technology Applications, Inc. (MSE) using funds provided by DOE.
