20 October 2003 <br /> AGE-NC Project No 95-0109 <br />' Page 3 of 4 <br />' above the screened intervals of the deep-screened wells MW-15 and MW-17 through MW-19 Data <br /> from wells MW-1 through MW-5 were not used to infer ground water flow direction or gradient <br /> because these wells are screened at different-intervals than the remaining wells - <br />' On 10 September 2003, ground water on-site was inferred to be flowing towards the south, and <br /> towards the southeast south of the site The ground water gradient was approximately 0 003 ft/ft <br />' Figure 3 illustrates the contoured ground water elevations, historical ground water flow directions <br /> k are summarized on Table 4 <br /> 1 <br /> 3 2 ANALYTICAL RESULTS OF GROUND WATER SAMPLES <br />' TPH-g was detected in ground water samples from wells MW-8, MW-9 and MW-14 at <br /> concentrations ranging from 630 micrograms per liter(µg/1)in MW-14 to 2,900 µg/l (MW-8) One <br />' or more BTEX compounds were detected in the same samples at concentrations as high as 77 µg/1 <br /> benzene (MW-14), 8 1 µg/1 toluene (MW-14), 12 µg/1 ethylbenzene (MW-9) and 340 µg/I total <br /> • xylenes (MW-8) <br />' TBA was detected in the water samples collected from wells MW-9 and MW-14 at concentrations <br /> of 12 µg/l and 9 9 µg/1,respectively 1,2-DCA was detected in samples collected from wells MW-7, <br />' MW-9,MW-14 and MW-16 at concentrations ranging from 0 76 gg/1(MW-7)to 22 µg/1 (MW-16) <br /> No additional fuel additives were detected above laboratory reporting limits <br />'i The analytical results for the September 2003 monitoring event are presented on Table 2 Historical <br /> analytical results are summarized on Table 3 The approximate extent of dissolved TPH-g,benzene <br /> and 1,2-DCA are depicted on Figures 4, 5 and 6 The laboratory reports(MAI Work Order Number <br />' 0309193) and chain-of-custody forms are included in Appendix B <br /> 4.0. DISCUSSION AND CONCLUSIONS <br /> Based upon data collected from the site, AGE finds <br /> Ground water on-site was inferred to be flowing towards the south,and towards the southeast <br /> south of the site The ground water gradient was approximately 0 003 ft/ft <br />' • TPH-g was detected in ground water samples from wells MW-8,MW-9 and MW-14 and at <br /> concentrations as high as 2,900 µg/1 (MW-8) <br />' • One or more BTEX compounds were detected in the same samples at concentrations as high <br /> as 77 µg/1 benzene(MW-14), 8 1 µg/1 toluene(MW-14), 12 µg11 ethylbenzene(MW-9)and <br />' 340 µg/1 total xylenes (MW-8) <br /> Advanced GeoEnvironmental,Inc <br /> 1 1 <br /> z <br />
