Announcements and Key Topics

EPA has released the Human Health Risk Assessment for the Bonita Peak Mining District Superfund site (HHRA). The HHRA evaluated potential risks to human health from exposures to contaminants that may be present in the mining district.

This year, snowpack is higher than average in the Animas River Basin, and the changes in the appearance of the water in the Animas River due to spring runoff may be more pronounced than usual. These changes may also be observed further downstream than is typical during this time of year. In addition, those in Durango and downstream communities may observe higher than normal levels of sediment in the Animas River due to runoff from the 416 Fire burn area. The high snowpack this spring also may delay the resumption of investigative and cleanup activities at the BPMD.

EPA has released the Interim Record of Decision that identifies interim remedial actions (IRAs) to be conducted at the site. EPA will begin work this summer on IRAs at 23 source areas, with full completion of all IRAs expected over the next three to five years.

New Site Information


EPA is maintaining contact information from individuals and/or companies wishing to be considered for work at the BPMD. Vendors or contractors interested in doing business related to BPMD should contact Cynthia Peterson (peterson.cynthia@epa.gov).
