Rinconada Mine cleanup
This former mercury mine produced an estimated 3,000 flasks of mercury since 1872, and operated intermittently until about 1961. The site includes lands managed by BLM and the U.S. Forest Service, plus private land.

Mill Tailings - Creekbed cleanup:
The "after cleanup" photo (below, at left) shows the restored creekbed with all mercury mill tailing materials removed. The tailings were excavated using heavy equipment and then trucked off site to a designated hazardous waste repository. The creek bed restoration project involved collaboration of both EPA and BLM technical staff, in order to create a streambed that was sufficiently durable to heavy storm events that would easily erode the stream banks, but allow development of a series of step-pools, approximating natural streambed restoration processes.
