The Cd’A River, Chain Lakes, and wetlands from Cataldo to Harrison are contaminated with heavy metals from the last century of mining in the Silver Valley. EPA is required by law to protect human health and the environment. The agency must comply with specific federal regulations, but within that frame, there is opportunity for the public to influence decisions.
EPA has begun initial studies on the ways contaminated sediment moves in the Coeur d’Alene River and Lower Basin waterways and wetlands. The conclusions drawn from this information and the methods and scope of the cleanup will ultimately be presented in a ROD (Record of Decision) Amendment. (A ROD defines the scope of a cleanup and how that cleanup is implemented over a period of several years.)
