BUNKER HILL MINING AND METALLURGICAL
KELLOGG, SHOSHONE COUNTY, IDAHO
- The toxic wastes at the Bunker Hill-Hillsides site are a public health hazard. People living in the vicinity of the underdeveloped hillsides of the Bunker Hill site, in the past, have been exposed to metals that can produce adverse health effects in the long term. The risk of such exposure continues to be present. It is most likely to occur from incidental ingestion of the soil. Concentrations of lead, arsenic, cadmium, and zinc are high in the surface soils of some areas slated for future development. Children displaying pica behavior are particularly at risk. It is also possible that exposure can occur through inhalation.
- The contamination can migrate as development occurs in these areas and the population increases. For this reason, this report makes recommendations aimed at insuring that people are aware of the current contamination and that soils are remediated before any future construction begins in the contaminated areas.
- Action should be taken to cease or reduce exposure to contaminated soils on hillsides (i.e. post notices of possible exposure hazards due to high lead content in soil, install fencing to prevent or reduce unauthorized access, and revegetate to prevent/reduce migration of contaminated soils).
- Ensure oversight and enforcement of the current institutional controls program during development of current unpopulated areas.
- Continue current efforts to educate and make residents aware of hazards posed by exposure to lead in the soil. Ensure that future residents of property developed on hillside areas are aware of hazards and of actions they can take to reduce exposure.
