Abstract
This report sets forth acceptable soil and sediment criteria for heavy metals released from abandoned hard rock mining sites as they relate to ecosystem management and protection of human health and wildlife. The USDI Bureau of Land Management (BLM) manages approximately 270 million acres of public lands, primarily in the Western U.S. These lands include several hundred thousand abandoned mining sites, some of which may be releasing heavy metals into the environment at levels toxic to wildlife.
