1, 19 January 2006 �• AGE-NC Project No 97-0312 IPage 3 of 4 ., (UST-2) and 35 76 feet (UST-6) below mean sea level (MSL), the average ground water elevation Iat the site during the second quarter 2005 was 35 05 feet below MSL, an Increase of 1 42 feet since the March-2005 monitoring event The ground water table occurred within the screened Intervals of " monitoring wells UST-2 through UST-6 Monitoring well UST-7-was designed to monitor deeper ground water, with a 5-foot screened Interval set at approximately 22 feet below the water table, since It Is possibly monitoring a different hydraulic zone,UST-7 was not used to determine gradient and flow direction The ground water flow direction during second quarter 2005 was radially Inwards towards a I northerly trending trough In the potentiometric surface (Figure 3), net ground water flow was Inferred to be towards the north at low hydraulic gradients ranging between 0 004 foot/foot(ft/ft)and 0 006 ft/ft Monitoring data collected from the adjacent Moore Truck Lines property Indicates a ground water flow direction towards the southeast (Figure 3) I 3 2 ANALYTICAL RESULTS OF GROUND WATER SAMPLES TPH-g was detected in the ground water samples collected from well UST-5 at a concentration of 200 micrograms per liter (µg/1) 1,2-DCA was detected In the samples collected from UST-5 and UST-6 at concentrations of 220 pg/l and 10 µg/1, respectively No other analytes were detected at or above laboratory reporting limits In the ground water samples " 'collected this quarter The laboratory report(CTEL Project No CT214-0506206),quality assurance/ quality control(QA/QC)reports,and chain of custody form are Included In Appendix C Analytical I results of water samples collected during the second quarter 2005 are summarized In Table 2 The analytical results of historical water samples are summarized In Tables 3 and 4 Documents confirming the upload of laboratory electronic deliverable format (EDF)'files and depth to water measurements to GeoTracker�are included in Appendix D 4.0. DISCUSSION AND CONCLUSIONS Based upon data collected from the site, AGE concludes IGround water elevation Increased approximately 142 feet at the site since the March 2005 monitoring event The Inferred ground water flow direction was generally toward the north Iat hydraulic gradients ranging between 0 004 foot/foot (ft/ft) and 0 006 ft/ft Advanced GcoEnvironmental,Inc
