Transport and Reactions of Petroleum Contaminants in the Unsaturated Soil Zone from Leaking Underground Tanks
Groundwaters are increasingly threatened by oil leaks, disposal of hazardous wastes, and landfill leachates migrating through the soil mantle (Wilson et al. 1981; MacKay et al. 1985). Several mechanisms control migration of toxics to underground aquifers (Short 1987), i.e., hydrological transport, adsorption/desorption, volatilization, and decomposition, including biodegradation. The fate and transport of petroleum products in the soil environment are complex and dynamic, including all of the above mechanisms (Grenny et al. 1987; Symons et al. 1988).
