Ile 17 April 2006 <br /> AGE-NC Project No 98-0432 <br /> Page 3 of 4 <br /> third quarter 2005 The ground water flow direction was inferred to be toward the northwest at a <br /> ' gradient of approximately 0 005 foot/foot (ft/ft) near the former UST locations (Figure 3) <br /> ' 3 2 GROUND WATER ANALYTICAL RESULTS <br /> No petroleum hydrocarbon compounds or fuel additives were detected in the samples analyzed from <br /> monitoring wells MW-1 through MW-8 Analytical results from ground water samples are <br /> summarized in Table 2 The laboratory report (CTEL Project No CT214-0602056), quality <br /> assurance/quality control (QA/QC)report,and chain of custody forms are included in Appendix B <br /> Documents confirming the upload of laboratory electronic deliverable format(EDF)files and depth <br /> to water measurements to GeoTracker are included in Appendix C <br /> 4.0. SUMMARY AND CONCLUSIONS <br /> ' The following conclusions were drawn from the results of this investigation <br /> Ile During the February 2006 monitoring event, ground water was approximately 3 18 feet <br /> higher than the July 2005 quarterly sampling event This elevation represents the highest <br /> ground water elevation observed at the site over five consecutive years of ground water <br /> monitoring The ground water flow direction was northwest at a gradient of 0 005 ft/ft in the <br /> area of the former USTs,which was west of the consistent,prevailing north to northwesterly <br /> flow directions at the site <br /> • No petroleum hydrocarbon compounds or fuel additives were detected in the samples <br /> analyzed from monitoring wells MW-1 through MW-8 <br /> ' S.O. RECOMMENDATIONS <br /> AGE recommends site closure, as outlined in the AGE-prepared Closure Summar Report, dated <br /> 04 October 2005, upon approval from the EHD t5+N D a.A. 1 40 w � 4] 7V 0 G <br /> ' af�orov! 1 X6 1 �vl�i 1rj l <br /> 14.0 �� /� <br /> �fi�� . ,s,� y <br /> ' 6.0.
