TPH-G was <br /> detected in six groundwater samples at concentrations ranging from 60 µg/L to 43,000 µg/L,. Benzene <br /> and ethylbenzene were detected at concentrations of 2 µg/L and 1.2 µg/L, respectively, in the <br /> groundwater sample from boring GP 117. BTEX constituents were not detected at or above the laboratory <br /> practical quantitation limit in the other groundwater samples. Detectable concentrations of PNAs in the <br /> seven groundwater samples ranged from 0.1 µg/L to 160 µg/L. Groundwater sample analytical results <br /> _ A <br /> CONDOR <br />
