excavation, and from SB-2, drilled on the east side of the former UST excavation contained <br /> elevated concentrations of TPH-as-diesel. Concentrations of TPH-as-diesel in soil were reported <br /> as high as 6,000 mg/kg at a depth of 15 feet bgs. Concentrations of TPH-as-diesel in <br /> groundwater were reported as high as 590,000 micrograms per liter (µg11). Benzene was also <br /> detected in groundwater at a concentration of up to 3.6 µg/l. Methyhtertfary butyl ether(MTBE) <br /> was not detected in any of the soil or groundwater-grab samples analyzed. The results of the soil <br /> and groundwater-grab sample analyses are summarized in Table 1. <br /> 5 <br />
