' 08 August 2005 `. AGE-NC Protect No 98-0534 ' Page 7 of 15 ' summarized in Table 4 Results of the May 2001 ground water monitoring event were reported in Quarterly Report - 2nd Quarter 2001, dated 06 September 2001, prepared by AGE u_ ' 08 January 2002-ground water levels were measured at MW-1 and MW-3 through MW-8 Ground water monitoring well MW-2 was not readily accessible or located during the sampling event Ground water levels averaged 7 8 feet below the tops of the well casings (above the screened interval), ground water flow direction at the site was inferred to be towards the north and south away from an east-west trending hydraulic saddle at the main UST area, with a gradient of approximately 0 009 to 0 01 ft/ft North of well MW-4, the ' water table was inferred to be rising with a gradient of 0 05 ft/ft, resulting in the formation of an elongated depression trending east-west located between wells MW-5 and MW-6 TPH-g was detected in the ground water samples collected from wells MW-3,MW-4,MW-6 and MW-7 at concentrations of 120 µg11, 110 µg/l, 90 µg11 and 800 µg/l, respectively Toluene was the only BTEX compound detected in the ground water samples,at a maximum concentration of 15 µg/l in MW-4 TPH-d was not detected in any of the samples MTBE was detected by EPA Method 8020 in the ground water samples from wells MW-3,MW-4, MW-6, MW-7 and MW-8 at concentrations of 6 2 µg/1, 14 µg/1, 30 µg11, 19 µg/1 and • 2 4 µg/1,respectively, MTBE was detected by EPA Method 8260 in the samples from wells MW-3, MW-4, and MW-6 at concentrations of 7 0 µg/1, 20 µg/1 and 43 µg11, respectively No other fuel oxygenates were detected in any of the analyzed samples Ground water elevations are summarized in Table 3, analytical results of ground water samples are ' summarized in Table 4 Results of the January 2002 ground water monitoring event were reported in Quarterly Report - 1 sr Quarter 2002, dated 03 April 2002_, prepared by AGE ' 14 June 2002 - ground water levels were measured at MW-1 and MW-3 through MW-8 Ground water monitoring well MW-2 was not readily accessible or located during the sampling event Ground water levels averaged 10 8 feet below the tops of the well casings ' (within the screened interval), ground water flow direction at the site was inferred to be towards the northeast away from the former UST area, with a gradient of approximately 0 009 to 0 01 ft/ft The ground water elevation of monitoring well MW-4 appeared anomalously low, out of the range of the surrounding wells by 1 foot, and further the well failed to recharge after purging, therefore the data from that well was not used to map the ground water elevation TPH�g was not detected in the ground water samples collected from ' wells Toluene was the only BTEX compound detected in the ground water samples, at a maximum concentration of 1 1,µg11 in MW-4 TPH-d was detected in the ground water samples collected from wells MW-4 and MW-6 at concentrations of 130 µg/1 and 53 µg/l, ' respectively MTBE was detect4by EPA Method 8260 in the samples from wells MW-3, MW-4,MW-6,MW-7 and MW-8 a�concentrations of 6 9 µg/1, 18 µg/l, 150 µg/1, 0 62 µg/1 ' Advanced GcoEnvironmental,Inc 1 '
