Health Assessment for Bunker Hill Mining and Metallurgical Complex, Kellogg, Shoshone County, Idaho, Region 10. CERCLIS No. IDD048340921. Addenda

摘要

The Bunker Hill site is listed, by the U.S. Environmental Protection Agency (EPA), on the National Priorities List (NPL). The 21 square-mile site includes the Bunker Hill mining and smelting complexes and the communities of Pinehurst, Page, Smelterville, Kellog, and Wardner, Idaho. Mining and smelting operations have occurred in the area (Silver Valley) since the 1880's. The Bunker Hill smelter discontinued operation in 1982. The former milling and smelting operation at the Bunker Hill Complex has left behind contaminated soils and deposits of slag, mine tailings, and other process residuals. Based upon the information reviewed, ATSDR has concluded that this site is of public health concern because of the risk to human health caused by the probable human exposure to hazardous substances at concentrations that may result in adverse health effects. Human exposure to heavy metals is probably occurring via ingestion, dermal, or inhalation exposure to contaminated surface soils, mine wastes and tailings, surface waters, or contaminated foodstuffs.
