' 16 October 2002 <br /> AGE-NC Project No 99-0584 <br />' Page 3 of 4 <br />' 32 ANALYTICAL RESULTS OF WATER SAMPLES <br /> There were no reported detections ofBTEX,TPH-g,DIPE,ETBE,TAME,TBA,or lead scavengers <br />' in any of the ground water samples analyzed <br /> Analytical results from ground water samples are summarized in Table 2 The laboratory reports <br />' (MAI Laboratory ID 0207389-1 to 5, quality assurance and quality control (QA/QC) reports and <br /> chain-of-custody forms are included in Appendix C <br /> I4.0. SUMMARY AND CONCLUSIONS <br />' Based upon data collected from the site, AGE concludes <br /> • The ground water flow direction in July 2002 at the site was inferred to be toward the <br /> northeast at a gradient of approximately 0 002 ft/ft, which is consistent with prior ground <br /> water flow directions and gradients <br /> • The ground water elevation increased approximately 1 5 feet over the last quarter <br /> Hydrocarbons and fuel additives were not detected m the groundwater sample collected from <br /> the monitoring wells Although MTBE-impacted soil up to 2,720 µg/kg has been detected <br /> at water-table depths(Appendix A),petroleum hydrocarbons and oxygenated fuel additives <br /> have not been detected during three of the six ground water monitoring events <br /> I <br /> I5.0. RECOMMENDATIONS <br /> Based on the results of this investigation, AGE recommends <br /> • Continued-quarterly monitoring at the site, the next monitoring event should be scheduled <br /> for October 2002 <br /> • Preparation and submission of a work plan to define the lateral distribution of MTBE- <br /> impacted soil and reconfirm MTBE concentrations at the westernmost former dispenser <br /> area(SB 1) <br /> I <br /> I - <br /> I <br /> I <br />
