Abandoned mine lands (AMLs) are those lands, waters and surrounding watersheds where extraction, beneficiation or processing of ores and minerals has occurred. AMLs can pose serious threats to human health and the environment. The EPA conducts and supervises investigation and cleanup actions at a variety of mine sites. The Agency has a range of resources related to the environmental risks and challenges present in investigating and cleaning up AMLs. The EPA also pursues opportunities to explore innovative reuse opportunities at mine sites.
