Comments

Comment (Environmental Factors): THERE WERE NO DISCHARGING ADITS ON SITE. THERE WERE THREE SHAFTS THAT DID NOT DISCHARGE BUT HELD WATER. SHAFT #3 WAS SAMPLED. ARSENIC AND CADMIUM EXCEEDED MAXIMUM CONTAMINANT LEVELS. THERE WERE TWO MONITORING WELLS ON-SITE THAT WERE POTENTIALLY DOWNGRADIENT AND ONE SPRING THAT WAS UPGRADIENT. THERE WERE OBSERVED RELEASES OF ARSENIC, CADMIUM, COBALT, COPPER, IRON, NICKEL, LEAD, AND ZINC IN THE WELLS, AND THE MAXIMUM CONTAMINANT LEVELS WERE EXCEEDED FOR CADMIUM AND ARSENIC. LUMP GULCH CREEK RAN THROUGH ERODED TAILINGS. THERE WERE OBSERVED RELEASES OF CADMIUM AND ZINC IN DOWNSTREAM SURFACE WATER IN THE CREEK. CADMIUM EXCEEDED MAXIMUM CONTAMINANT LEVELS. ELEVATED UPGRADIENT METAL CONCENTRATIONS INDICATED THE POSSIBLE PRESENCE OF AN UPGRADIENT SOURCE.
