Abstract

Chlorinated organic solvents introduced to unlined lagoons at an industrial waste-water treatment plant in the Inner Piedmont of South Carolina resulted in ground-water contamination of a fractured-rock aquifer. Part of the ground-water contamination discharges to Little Rocky Creek, downgradient from the waste-water treatment plant. Passive vapor collectors were buried in the bottom sediment of the creek to locate areas where ground water contaminated with volatile organic compounds was discharging to the creek. High concentrations of volatile organic compounds (VOCs) were found in passive vapor collectors in an area where VOCs were known to be discharging from ground water to surface water. This area was also a site where very low frequency electromagnetic anomalies (interpreted as fracture zones) intersected the creek or converged near the creek. The data show that passive vapor collectors in bottom sediment of Little Rocky Creek provided information on the location of fractures that were discharging contaminated ground water to surface water.
