State AML Programs and Inventories

Abandoned mines degrade water quality and cause significant concerns to fish, wildlife, and human health in every western state. Unfortunately, most western states lack a consistent funding source to deal with these threats. Despite the difficult funding situation, a few states have completed inventories of the abandoned mines under their jurisdiction. For more information about abandoned mines in your state, check the list below for the relevant state authority, their website address, and the state abandoned mine inventory, if any.
