Health assessment for Anaconda Smelter Site, Anaconda, Deer Lodge County, Montana, Region 8. CERCLIS No. MTD093291656. Final report

Technical Report ·
OSTI ID:5122948

The Environmental Protection Agency (EPA,) Region VIII has requested that the Agency for Toxic Substances and Disease Registry (ATSDR) evaluate the Remedial Investigation and Feasibility Study (RI/FS) Reports for the Mill Creek, Montana Anaconda Swelter Site. Extensive environmental sampling by EPA, urinary arsenic surveys conducted by the Centers for Disease Control, the Endangerment Assessment (EA,) and the RI have consistently shown extensive contamination of soils and house dust by arsenic, cadmium, and lead, and episodic contamination of drinking water with arsenic above the EPA Maximal Contaminant Level (MCL). The RI presents results of calculations showing, potentially, an elevated excess lifetime risk of skin cancer for males from chronic exposure to arsenic by ingestion. The calculations were performed only for males, the most sensitive subpopulation; however, the female subpopulation would also be expected to have a lesser but elevated excess skin cancer risk from ingestion of arsenic. The long-term health effects of cadmium and lead are additional concerns. When EPA makes a Record of Decision (ROD) for the Mill Creek site, ATSDR can more readily make a definitive statement about the adequacy of the chosen Alternative for reducing the public health risk at Mill Creek.
