Each groundwater sample was labeled according to the specific project number, the <br /> borehole/hydropunch number, and the date when the sample was collected. <br /> The laboratory analyses indicate gasoline and diesel constituents in the groundwater at each <br /> ' borehole. BTEX concentrations were detected ranging from 1.3 µg/l to 260 µg/1. TPH-G <br /> concentrations were detected in the groundwater samples collected from HP-1 and HP-3 at <br /> ' concentrations of 0.22 mg/l to 1.0 mg/l. TEPH (diesel) was detected in HP-1, HP-2, and HP-3 at <br /> concentrations ranging from 0.24 to 0.79 mg/l. The results of the groundwater analyses are shown in <br /> ' Table 2, below. Laboratory report sheets indicating analytical methods used, detection limits, and <br /> results of analyses are located in Appendix C. <br /> 1 <br /> L� CONDOR <br />
