摘要

The historic Homestake Gold Mine at Lead, SD, was closed in December of 2001 after 125 years of operation. Since closure, the mine was selected by the National Science Foundation as the proposed host site for the Deep Underground Science and Engineering Laboratory. Pumps in the 2,480-m- (8,150-ft-) deep mine were shut off on June 10, 2003. Post-closure flooding of the mine has resulted in rising water levels that reached the 1,524 m (5,000 ft) level in July of 2007. The rate of water inflow into the mine is about 47 L/s (750 gpm). A plot of water level vs. time shows that the rise has not followed an exponential decay curve. When the pumps are turned on for dewatering, the rate of water-level decline will be monitored. Water in the Homestake mine contains arsenic derived from arsenopyrite. In samples of mine water, the median concentration of arsenic was 0.012 mg/L, which is below South Dakota's surface-water aquatic life standard of 0.15 mg/L for beneficial use. [PUBLICATION ABSTRACT]
