QA/QC reports and chain of custody form are included in Appendix C Documents confirming the <br /> upload of laboratory electronic deliverable format(EDF)files and depth to water measurements to <br /> GeoTracker are Included in Appendix D <br /> 4.0. SUMMARY AND CONCLUSIONS of <br /> Based on the data collected from the site, AGE concludes <br /> 1 <br /> b� <br /> • The ground water flow direction was modeled to then ast at a gradient of 0 002 ft/ft, which <br />' is generally consistent with flow in the area <br /> • TPH-g and BTEX compounds were detected in ground water samples collected from wells <br />' MW-1 through MW-3, at maximum concentrations of 110,000 µg/l TPH-g, 6,300 µg/1 <br /> benzene, 30,000 µg/1 toluene, 4,100 µg/1 ethylbenzene and 25,300 µg/1 total xylenes from <br />' well MW-1 <br /> • 1,2-DCA and EDB were detected in the ground water sample from MW-1 at concentrations <br /> of 570 µg/1 and 1,500 µg/1, respectively <br />' • Petroleum hydrocarbon-impact to ground water is not defined in any direction <br /> Advanced GeoEnvironmental,Inc <br />
