13 dune 2005 <br /> AGE-NC Project No 02-0962 <br /> IPage 3 of 4 <br /> 32 ANALYTICAL RESULTS OF GROUND WATER SAMPLES <br /> None of the constituents listed in Section 2 3 were detected in ground water samples from any of <br />' the three ground water monitoring wells Analytical results of ground water samples are summarized r <br /> In Table 2 The laboratory report (CTEL Project No CT214-0503028), quality assurance/quality <br /> control (QA/QC) reports, and chain of custody form are Included in Appendix D Documents <br /> confirming the upload of laboratory electronic deliverable format (EDF) files and depth to water <br /> measurements to GeoTracker are Included in Appendix E <br /> 4.4. SUMMARY AND CONCLUSIONS <br />' Based upon data collected during this monitoring event, AGE concludes the following <br /> • Depths to ground water ranged from 19 55 feet to 19 80 feet below the tops of the well <br /> Icasings Ground water elevation at the site averaged approximately 7 73 feet below MSL, <br /> Indicating an Increase In ground water elevation of 2 20 feet since the last ground water <br /> monitoring event In November 2004 <br /> During the March 2005 ground water monitoring event, ground water was Inferred to be <br /> flowing toward the north-northwest under a nearly flat gradient of approximately <br /> 0 0003 foot/foot(ft/ft) <br /> None of the constituents of concern were detected In ground water samples from any of the <br />' three ground water monitoring wells for the third consecutive quarter <br /> • The lateral and vertical extents of dissolved petroleum hydrocarbon contamination have not <br /> yet been defined <br /> 5.0. RECOMMENDATIONS <br /> In February 2005, the EHD approved a work plan for the Installation of additional ground water <br /> monitoring wells at the site to,confirm the dissolved petroleum hydrocarbons AGE plans to begin <br /> the next phase of the Investigation,in the third quarter 2005 <br />' Based on the findings of the environmental activities recounted In this report, AGE recommends <br /> reduction of quarterly monitoring events to annual monitoring events for the three non-impacted <br /> wells, MW-1 through MW-3 <br /> I <br /> IAdvanced GeoEnvironmental,Inc <br />
