Concentrations of hydrocarbon compounds in ground water from the unconsolidated alluvium and bedrock formations near Greear, Ky., have resulted in the abandonment or restrictive use of several domestic and commercial water-supply wells. Laboratory analyses of water samples from area wells indicated levels of hydrocarbon compound contamination in excess of 1,000 times the U.S. Environmental Protection Agency's Maximum Contaminant Levels for benzene, toluene, and total xylenes. Examination of the soil, soil gas, and groundwater resources of the study area determined a plume of hydrocarbon compound contamination in the unconsolidated alluvium at and around the active gasoline station. On-site analysis of soil-gas samples using a portable gas chromatograph at and around the gasoline station indicated concentrations of total volatile organic compounds as high as 134 parts per million. Laboratory analysis of water samples from monitor wells, installed during the investigation and screened in the unconsolidated alluvium, confirmed the presence of hydrocarbon compounds in the ground water. Concentrations of benzene (5,800 micrograms per liter) and ethylbenzene (810 micrograms per liter) exceeded the Maximum Contaminant Levels established by the U.S. Environmental Protection Agency. The detection of methyl-tertiary-butyl-ether, an octane-enhancing additive used in unleaded gasolines and only produced commercially since 1979, in several of the groundwater wells indicated that the source of the hydrocarbon compound contamination is associated, in part, with facilities that have stored, used, or spilled unleaded gasoline. Migration of the hydrocarbon compounds from the alluvium into the bedrock aquifers was probably by natural percolation, induced infiltration caused by the pumping of area water-supply wells, and the mixing of petroleum products with ground water in the well bores during pumping.
