Sulfate reduction in freshwater sediments receiving acid mine drainage
Abstract
One arm of Lake Anna, Va., receives acid mine drainage (AMD) from Contrary Creek (SO/sub 4//sup 2 -/ concentration = 2 to 20 mM, pH = 2.5 to 3.5). Acid-volatile sulfide concentrations, SO/sub 4//sup 2 -/ reduction rates, and interstitial SO/sub 4//sup 2 -/ concentrations were measured at various depths in the sediment at four stations in four seasons to assess the effects of the AMD-added SO/sub 4//sup 2 -/ on bacterial SO/sub 4//sup 2 -/ reduction. Acid-volatile sulfide concentrations were always an order of magnitude higher at the stations receiving AMD than at a control station in another arm of the lake that received no AMD. Summer SO/sub 4//sup 2 -/ reduction rates were also an order of magnitude higher at stations that received AMD than at the control station (226 versus 13.5 mmol m/sup -2/ day/sup -1/), but winter values were inconclusive, probably due to low sediment temperature (6/sup 0/C). Profiles of interstitial SO/sub 4//sup 2 -/ concentrations at the AMD stations showed a rapid decrease with depth (from 1270 to 6 ..mu..M in the top 6 cm) due to rapid SO/sub 4//sup 2 -/ reduction. Bottom-water SO/sub 4//sup 2 -/ concentrations in the AMD-receiving arm were highestmore »

These data support the conclusion that there is a significant enhancement of SO/sub 4//sup 2 -/ reduction in sediments receiving high SO/sub 4//sup 2 -/ inputs from AMD.},
