Environmental Factors THERE WERE NO TAILINGS ASSOCIATED WITH THIS SITE. THERE WERE TWO ADIT DISCHARGES. ONE WAS ASSOCIATED WITH THE LARGE ADIT AND DUMP IN THE DRAINAGE DIRECTLY UPSTREAM FROM THE MAIN LEVEL SHAFT AREA. NONE OF THE MAXIMUM CONTAMINANT LEVELS WERE EXCEEDED IN THE SAMPLE FROM THIS DRAINAGE. THE SECOND DRAINAGE WAS ASSOCIATED WITH THE CAVED ADIT ON THE HILLSIDE NORTH OF THE MAIN LEVEL SHAFT AREA. THE MAXIMUM CONTAMINANT LEVELS FOR CADMIUM, NICKEL, AND ANTIMONY WERE EXCEEDED IN THE SAMPLE FROM THE SECOND DRAINAGE. THIS DISCHARGE SEEPED BACK INTO THE GROUND PRIOR TO REACHING THE DRAINAGE BELOW. ROCK CREEK, A SMALL PERENNIAL TRIBUTARY TO BELT CREEK, FLOWED THROUGH THE SITE. SURFACE WATER SAMPLES DID NOT DOCUMENT AN OBSERVED RELEASE OF ANY OF THE METALS ANALYZED. THE MAXIMUM CONTAMINANT LEVEL FOR CADMIUM WAS EXCEEDED BOTH UP AND DOWN STREAM OF THIS SITE AND THEREFORE WAS NOT DIRECTLY ATTRIBUTABLE TO THIS SITE. THE STREAM SEDIMENT DATA DID DOCUMENT AN OBSERVED RELEASE OF MERCURY.
