Cecchuu, Cecchuu, and Gnovannom, Fueling Island <br /> ' <br /> Analytical results for wells UST-2 through LUST-5 are listed in Table 2 - <br /> Summary of <br /> Ground Water Samples Analytical Results. The certified laboratory reports and chain-of- <br /> custody documentation are presented in Appendix B <br />�1 4n October 4, 1996, ground water from UST-5 was reported to contain TPH-D at a <br /> concentration of 100 micrograms per liter (µg/1) TPH-G in ground water from UST-5 <br /> was reported as 450 µg11. BTEX in ground water from UST-5 was reported as 3 8 µg11, <br /> 12 µg11, ND, and 0 99 µg11, respectively MTBE was reported as 11 µg11 in UST-5 <br /> TPH-D, TPH-G, MTBE and BTEX were reported as non-detect in ground water samples <br /> collected from monitoring wells UST-2 through UST-4 These findings are illustrated on <br /> 1 Figure 4 - Petroleum Hydrocarbons in Ground dater <br /> 4.3 QunaUty Cont:r®ll <br /> Quality control samples collected by ESE included a duplicate sample (from monitoring <br /> well UST-2) and a trip blank (prepared by McCampbell) The analytical results for the <br /> duplicate sample were non-detect as was the primary sample and showed a 0 relative <br /> percent difference from the primary sample collected from monitoring well UST-2 No <br /> target analytes were detected in the trip blank sample <br /> Laboratory quality control analyses included method blanks, matrix spikes and surrogate <br /> spikes These data were reviewed by ESE, which verified the following <br /> o The method blanks did not contain any of the analytes, and <br /> 0 The analytical results for the matrix spike samples and matrix spike duplicate <br /> samples were within acceptable recovery ranges for BTEX (Wagner, 1992). <br /> F 169254W\gtrly rptl3gtc96 rpt 7 Environmental Science&Enguneenng, Inc <br />
