Announcements and Key Topics

EPA has posted the 2016–2018 Seeps, Springs, and Draining Mines Characterization Report (PDF) (481 pp, 15.2 MB, About PDF).

The report summarizes sampling events beginning in the fall of 2016 and running through the fall of 2018 that were conducted by the Mountain Studies Institute on behalf of EPA. These sampling events will help to better understand water quality and quantity emerging from seeps, springs and draining mine adits in the mining district. The sampling events focused on the Upper Cement Creek watershed above Silverton.

Community Advisory Group

The Bonita Peak Community Advisory Group (CAG) was established in 2019 and is an independent group that serves as an informational conduit between diverse community interests and U.S. EPA and its governmental partners with regard to activities at the Bonita Peak Mining District Superfund site and their effects on the Animas River watershed within Colorado. In its advisory capacity, the CAG desires outcomes that are: protective of human health and the environment, feasible and practicable, conducted expeditiously and efficiently, and mindful of community cultural, social and economic interests.
