All but five samples exhibited detectable quantities of the BTX&E compounds. Within each borehole sampled, the maximum BTX&E concentrations were detected within the sample collected from a 9 ' depth. For TPH, the maximum concentrations, with the exception of borehole 43 , were detected in the sample collected from a 3 ' depth. According to the L.U.F.T. (Leaking Underground Fuel Tank Manual March 1989 edition) , the BTX & E concentrations detected in the soils at the site exceed allowable levels based on the site characteristics (i.e. , depth to groundwater less than 251 ) . The recommended allowable levels are typically based on TPH concen- trations, which, for this site would be 10 mg/kg. The TPH value is utilized because levels for BTX & E are not applicable at a TPH concentration of 10 mg/kg (gasoline) . However, ultimate cleanup levels are determined on a case by case scenario based on specific site characteristics. Site conditions such as the area asphalt surface, lack of adjacent potable water supply sources, ongoing groundwater cleanup at the site and lack of free product within the groundwater may provide some latitude regarding soil contamination clean up levels, rather than strict adherence to the LUFT guidelines. 6 -
