AGE-NC Project No 02-0926 <br /> ' Page 3 of 4 <br /> depicting the approximate distribution of dissolved 1,2-DCA is depicted on Figure 4 No othertarget <br /> ianalytes were detected at or above laboratory detection limits in the ground water samples analyzed <br /> Analytical results of groundwater samples are summarized in Table 2 The laboratory report(CTEL <br /> Project No CT214-0410063), quality assurance/quality control (QA/QC) report, and chain of <br /> custody forms are included in Appendix C Documents confirming the upload of laboratory <br /> ' electronic deliverable format (EDF) files and depth to water measurements to GeoTracker are <br /> included in Appendix D <br /> ' 4.0. SUMMARY AND CONCLUSIONS <br /> ' Based on data collected at the site, AGE concludes <br /> • Depth to ground water at the site averaged approximately 44 50 feet bsg on 11 October 2004 <br /> ' • Ground water elevation in the monitored area ranged from 25 05 feet to 26 28 feet below <br /> MSL Flow direction was inferred to be toward the northeast under a gradient of <br /> approximately 0 021 ft/ft <br /> '• TPH-g, benzene, toluene, and xylenes were detected in the ground water sample collected <br /> from monitoring well MW-3 at concentrations of 110 micrograms per liter(µg/1), 6 9 µg/l, <br /> 1 3 2 µg/l, and 113 gg/l, respectively 1,2-DCA was detected in the ground water samples <br /> collected from wells MW-1 and MW-3 at concentrations of 8 8 µg/l and 86 µg11, <br /> respectively <br /> 1 ' <br /> ' 5.0. RECOMMENDATIONS <br /> Based on the findings recounted in this report, AGE recommends <br /> ' Continuation of quarterly ground water monitoring events, the first quarter 2005 ground <br /> water monitoring event was performed in January 2005 <br /> ' Preparation of a work plan to define the vertical and lateral extent of soil and ground water <br /> contamination <br /> 6.0. LIMITATIONS <br /> Our professional services were performed using that degree of care and skill ordinarily exercised by <br /> environmental consultants practicing in this or similar localities The findings were based upon field <br /> ' Advanced GeoEnviroamental,inc <br />
