| Environmental Factors | THE TAILINGS MAY ERODE INTO CATACRACT CREEK DURING STORM EVENTS. THE ADIT DISCHARGE AT ADIT #2 EXCEEDED THE MAXIMUM CONTAMINANT LEVEL FOR ARSENIC AND CADMIUM. THE DISCHARGE ENTERED A SMALL DIVERSION DITCH FROM CATARACT CREEK WHICH FLOWED THROUGH THE DUMP AND THEN RETURNED TO THE CREEK. WATER SAMPLES FROM CATARACT CREEK WERE NOT COLLECTED DURING THIS INVESTIGATION DUE TO HIGH RELATIVE FLOWS. SEDIMENT SAMPLES COLLECTED FROM CATARACT CREEK DOCUMENTED OBSERVED RELEASES OF ARSENIC, COPPER, LEAD, AND ANTIMONY. |
