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, multidisciplinary 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.
