| Environmental Factors | THIS SITE WAS RECLAIMED BY THE MONTANA DEPARTMENT OF STATE LANDS/ABANDONED MINE RECLAMATION BUREAU IN 1987. WASTE ROCK DUMPS AND TAILINGS PONDS WERE ALMOST COMPLETELY REVEGETATED. ACCURATE ESTIMATION OF THE VOLUME OF TAILINGS WAS DIFFICULT DUE TO COVERING AND GRADING ACTIVITIES THAT OCCURRED DURING THE RECLAMATION ACTIVITIES. SPRING CREEK FLOWED ALONG THE RECLAIMED WASTE ROCK AND TAILINGS IMPOUNDMENTS. OBSERVED RELEASES TO SPRING CREEK (SEDIMENT) WERE DOCUMENTED FOR CADMIUM, COPPER, LEAD, AND ZINC. NO MAXIMUM CONTAMINANT LEVELS WERE EXCEEDED IN SPRING CREEK WATER SAMPLES. THE UNNAMED TRIBUTARY COMING INTO SPRING CREEK FROM THE NORTHWEST CONTAIMED ELEVATED LEVELS OF CADMIUM, COPPER, LEAD, AND ZINC. MAXIMUM CONTAMINANT LEVELS WERE EXCEEDED FOR CADMIUM AND COPPER IN THIS TRIBUTARY. |
