Cecchrru, Cecchmr, and Gtovannont, Fueling Island <br /> 270 µg11 BTEX was reported as 1 2 µg11, 3 1 µg11, ND, and 15 µg11, respectively <br /> TPH-D, TPH-G 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 /> Figure 4 - Petroleum Hydrocarbons in Ground Water <br /> 4.3 Qua Uty C®ntir®ll <br /> Quality control samples collected by ESE included a duplicate sample (from momtormg <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 /> a The method blanks did not contain any of the analytes, and <br /> or the matrix spike samples and matrix spike duplicate <br /> The analytical results for p P P P <br /> asamples were within acceptable recovery ranges for BTEX (Wagner, 1992) <br /> IJ <br /> f 169254M\gtrly rptl1gtr96 rpt 7 Environmental Science&Engineering, Inc <br /> Mi <br /> _... _... <br />
