AGE-NC Project No 99-0592 <br />' Page 3 of 4 <br />' Depth to water and ground water elevations are summarized in Table 1 Figures 3 and 4 illustrate <br /> the contoured ground water elevations <br />' 32 ANALYTICAL RESULTS OF GROUND WATER SAMPLES <br />' No analytes of concern were detected above laboratory reporting limits in the samples collected for <br /> the third and fourth quarter monitoring events <br />' Analytical results for the ground water samples from the September and November 2004 monitoring <br /> events are summarized in Tables 2 and 3 The laboratory reports (CTEL Project Nos CT214- <br /> 0409194 and CT214-0411131),quality assurance/quality control(QA/QC)and chain of custody are <br />' Included in Appendix B Documents confirming the upload of laboratory electronic deliverable <br /> format (EDF) files and depth to water measurements to GeoTracker are included in Appendix C <br /> 1 4.0. SUMMARY AND CONCLUSIONS <br />' . Based on the findings from this Investigation, AGE concludes <br /> • Ground water at the site for the September 2004 monitoring event was Inferred to be flowing <br />' toward the west-southwest at an average gradient of 0 005 Wft, ground water for the <br /> November 2004 monitoring event was inferred to be flowing toward the northeast at an <br />' average gradient of 0 0006 ft/ft The September 2004 ground water flow direction represents — <br /> a reversal to the normal northeasterly flow direction at the site <br /> • The average ground water elevation at the site decreased approximately S 68 feet between <br />' the June and September monitoring events, but increased approximately 3 83 feet between <br /> the September and November 2004 monitoring events <br /> • Petroleum hydrocarbon-impacted ground water appears to be limited to the area near <br /> monitoring well MW-1 None of the target analytes were detected in third and fourth quarter <br /> 2004 ground water samples collected from MW-4 and DW-1 <br /> 1 <br /> 5.0. RECOMMENDATIONS <br /> Based on the results of this investigation,AGE recommends consideration of the Moore Truck Lines <br /> site for closure AGE,has submitted Closure Summary Report, dated 30 August 2004 Pending site <br /> closure,AGE recommends continued quarterly ground water monitoring,the next monitoring event <br /> is scheduled for March 2005 � X <br /> Advanced GeoEnvvonmental,Inc <br />
