The U.S. Geological Survey's Toxic Substances Hydrology Program investigated the fate and transport of hydrocarbons in the unsaturated zone and shallow groundwater at a gasoline-spill site in Galloway Township, New Jersey. Research focused on three interrelated themes: groundwater contaminant geochemistry; estimation of microbial degradation rates of hydrocarbons on the basis of rates of gas transport in the unsaturated zone; and vapor-extraction remediation design. Contaminant geochemistry work produced a water-quality database that indicated zones of aerobic biodegradation adjacent to zones of anaerobic degradation with sharp chemcial-concentration gradients in narrow interfacial zones. The analysis of gas transport in the unsaturated zone provided a method for quantifying rates of aerobic biodegradation in the capillary zone and shallow groundwater. Mathematical models were developed to simulate vapor extraction remediation and to optimize system design.
