I ' 17 June 2002 . AGE-NC Project No 99-0559 ' Page 4 of 7 ' that the well samples,on the assumption that the elevation will reflect hydrostatic conditions within the sampled HUs HU 1 and HU2 ' Ground water elevation data collected from monitoring wells MW-1, MW-3, MW-4, and MW-5A through MW-8A ranged between 28 58 feet (MW-8A) and 29 01 feet (MW-6A) below mean sea ' level (MSL), and at the former UST location appeared to be flowing within a ground water trough towards the south-southwest,with a hydraulic gradient of 0 004(Figure 3) Ground water elevation increased approximately 6 2 feet over the last quarter The top of the ground water table was within ' the screened intervals of the wells The ground water elevation for well MW-2 (31 64 feet below MSL) was not corrected for the ' presence of free-product, the skimmer was removed from the well full of product and a thickness measurement was not collected ' f1U3 and HU4 Ground water elevation data collected from monitoring wells MW-5B through MW-8B ranged ' between 28 95 feet(MW-5B) and 29 72 feet(MW-8B)below MSL and was inferred to be flowing toward the southeast with a hydraulic gradient of 0 0065 (Figure 4) ' HU5 ' Within the upper portion of HU5 (Upper HU5), screened between 125 and 135 feet bsg, ground water elevation data collected from monitoring wells MW-5C through MW-8C ranged between 28 85 feet (MW-8C) and 29 06 feet (MW-7C) below MSL and at the former UST release was ' inferred to be flowing toward the north with a hydraulic gradient of 0 0016 (Figure 5) Within the lower portion of HU5 (Lower HU5), screened between 148 and 160 feet bsg, ground ' water elevation data collected from monitoring wells MW-5D,MW-71)and MW-8D ranged between 28 63 feet(MW-8D)and 29 14 feet(MW-7D)below MSL and was determined to be flowing toward the northwest with a hydraulic gradient of 0 007 (Figure 6) ' HU6 IGround water elevation data collected from monitoring wells MW-5E through MW-8E ranged between 29 20 feet (MW-5E) and 29 48 feet(MW-7E)below MSL and was inferred to be flowing toward the northwest with a hydraulic gradient of 0 003 (Figure 7) Advanced GeoEnvironmental,Inc
