SITE BACKGROUND

The 3.2-acre Celtor Chemical Works site, located in the northern Hoopa Valley Indian Reservation, is the location of a former ore concentrating facility that processed sulfide ore. Wastes from the milling operations and processed ore generated acidic runoff and elevated metals concentrations in the soils throughout the site. The Trinity River flows along the site and supports the only fish resources for the Hoopa Indians. After cleanup, EPA took the site off the Superfund program’s National Priorities List (NPL) in 2003.
