The National Academy of Sciences Report on Superfund and Mining Megasites: Lessons from the Coeur d'Alene River Basin
You will need the free Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more.
The National Academy of Sciences (NAS) performed an independent evaluation of EPA's scientific and technical practices related to the Coeur d'Alene Basin Superfund site in northern Idaho. Areas of the cleanup examined include: site characterization, human and ecological assessment, remedial planning and decision-making. EPA appreciates the Academy's scientific scrutiny and wishes to thank the distinguished panel members who contributed to the report.
EPA anticipates the report's recommendations will aid our long-standing commitment to use the best available science to protect the environment, human health and the communities of the Coeur d'Alene Basin. EPA will consider the NAS report's recommendations and where appropriate translate those findings into action.
