Elevated concentrations of Cu, Pb, Zn, and Cd occurred in stream sediments below both the Pecos mine and Alamitos Canyon mill sites, before reclamation began. Collectively, multi-disciplinary studies suggest that Cu, Pb, Zn, and other metals were eroded and leached from the Pecos mine waste pile and the tailings piles in Alamitos Canyon.
