The Idaho Lakeview Mine and Mill is an inactive silver and lead mine located near Lakeview, Bonner County, Idaho. The primary contaminants of concern are arsenic and lead, and potential human health and environmental impacts from the historic mine waste present at the site include public health and safety risks due to elevated contaminant concentrations in soil and surface water, and increased sediment load to surface water. The average concentrations of arsenic and lead at the two areas to be addressed by the removal action (South West Rock Dump and Mill) are 4,234 and 1,654 mg/kg, and 8,560 and 3,340 mg/kg, respectively. Chloride Gulch Creek is in direct contact with the South West Rock Dump. The creek is a tributary of Gold Creek, which harbors thye second most important adfluvial bull trout spawning population in the Lake Pend Oreille watershed. The site is a mixed-ownership hardrock mine site, located partially on private and partially on National Forest System lands located within the boundaries of the Idaho Panhandle National Forests. The USFS and EPA entered into a Memorandum of Understanding, and the USFS through an Interagency Agreement is funding EPA for costs associated with cleanup of mine waste contaminated materials located on public land. Mine waste contaminated material will be excavated and consolidated beneath a protective barrier at a nearby USFS repository.
