G <br />it <br />1� <br />Fj <br />n <br />n <br />G <br />F-1 <br />0 <br />F, <br />5. ANALYTICAL RESULTS <br />Results of the laboratory analyses indicated that the sample from the pea gravel <br />contained no detectable concentrations of TPH-G, BTEX, Cd or Pb. Low <br />concentrations of Cr, Ni and Zn were detected as well as 9.1 parts per million (ppm) of <br />TPH-D (see Table 1 and Appendix A). <br />Results of the laboratory analyses of soil samples collected from beneath the four <br />UST's (T1-1, T1-2, T2-1, T2-2, T3-1, T3-2, T4-1, T4-2), the three dispensers (D-1, D-2, <br />D-3) and the product delivery line (PL -1) are shown in Table 2, the laboratory report is <br />included in Appendix A. As shown in this table the detected concentrations of BTEX, <br />MTBE and Pb are either very low or not detected. In addition, when the analyses was <br />performed, TPH-D and TPH-G were not detected in soil samples from beneath UST's <br />-1, -, T-3 and dispenser D-3. WhileTPH-D was detected at the detection limit i <br />sample PL -1, the laboratory report (Appendix A) has classified this detection as an <br />unidentified hydrocarbon, which would indicate a hydrocarbon source other than diesel. <br />Relatively high concentrations of TPH-D were detected in samples T4-2 and D-2. <br />Laboratory analytical results indicate that TPH-D and TPH-G were detected in samples <br />collected from beneath UST T-4 and dispensers D-1 and D-2. However, all four TPH-G <br />detection's and the TPH-D detected in sample D-1 were classified in the laboratory <br />report as an unidentified hydrocarbon (Appendix A) which would indicate a <br />hydrocarbon source other than gasoline or diesel fuel at these locations. <br />M1Aw:1&4-261%UST.RPT 126 -OCT -98) <br />
