ANALYTICAL RESULTS OF SOIL SAMPLES <br /> A total of eight soil samples were collected and analyzed for TPH-g,BTEX;EDB, 1;2-DCA and the - r <br /> suite of five fuel'additives, including MTBE. <br /> No analytes were detected at or above laboratory reporting limits in the soil sample analysis..The <br /> „ approximate extent of petroleum hydrocarbon-impacted soil is depicted'on Figures 5, 6 and 7.' <br /> Analytical results of soil samples are summarized on Table 2. The laboratory reports(MAI Lab I.D. <br /> r No 0210562-001 through 0210562-008),quality assurance and qualitycontroh(QA/QC)report and <br /> chain-of custody forms are included in-Appendix E. <br /> 3.4. ANALYTICAL'RESULTS OF GROUNDWATER SAMPLES <br /> 1 TPH'g was detected in the water samples collected from monitoring p rzng wells MW2, MW5 and MW8 <br /> at concentrations of 81 µg11, 180µg/l and 170 jtg/l,respectively.TPH-d was detected in the samples <br />' collected from monitoring wells MW2,MW5,MW7 and MW8 at concentrations of 65 µg/1,87 <br /> 77 µg/1 and 90 µg/l, respectively <br />' Benzene was detected. in the water samples collected from'wells MW2, 'MW5 and-MW8 at <br /> concentrations of 15 µg/1, 1.1 µg/1 and 4.0 µg/1, respectively. Toluene was detected in the samples <br /> from wells MW7 and MW8 at concentrations of 0.88 µg/1 and 1.7 µg/i, respectively; ethylbenzene <br /> was detected in the.samples from:wells MW2,MW5,-MW6 and MW8 at concentrations as high as <br /> 8.4 µg/1; and xylenes were detected in the samples collected from wells MW2,MW5 and MW8 at <br /> concentrations as high as 21 µg/1:No other analytes were detected at or above laboratory reporting <br /> limits in the water samples collected from the monitoring wells. A map showing the approximate" r <br /> extent of dissolved benzene is presented in Figure.8. <br /> I , " Current and j revi6us analytical results are summarized on Table 3.
