Summary

EPA has begun its sixth review of the environmental cleanup at the Bunker Hill Superfund site in northern Idaho – also known as the "Coeur d’Alene Basin Cleanup." EPA is required to review Superfund sites every five years when contaminants remain on site to make sure that cleanup actions continue to protect human health and the environment.

The site was first added to the National Priorities ListA list of sites, many nominated by the states, for hazardous waste cleanup under Superfund. in 1983. Since then, EPA and its partners have made great progress in cleaning up properties, mine and mill sites, areas where people recreate, and many other places where heavy metals pose a risk. The concentration of lead in the blood of local children has been reduced by more than 50% from historically high levels to below the CDC’s current reference level of 5 micrograms/deciliter. However, much work remains and a complete cleanup will take decades.

Community members with information or ideas to share about the site are invited to participate in the public comment period for our review.
