Superfund Record of Decision (EPA Region 8): East Helena, MT. (First remedial action), November 1989
Abstract
The 80-acre East Helena site, in East Helena, Lewis and Clark County, Montana, is a primary lead smelting facility that has been in operation since 1888. Prickly Pear Creek flows near the site and has been found to contain elevated levels of arsenic and lead. A 1984 remedial investigation identified elevated levels of metal contamination in soil, livestock, plants, and ground and surface waters with the sources of onsite contamination being primary and fugitive emissions and seepage from process ponds and process fluid circuitry. The primary contaminants of concern in the process ponds are metals including arsenic and lead. The selected remedial action for this site includes excavating and smelting 55,150 cubic yards of soil and/or sediment from all four process ponds and multi-media monitoring after individual remedial activities are implemented at three of the process pond areas.
