i15 February 2002 AGE-NC Project No 99-0559 EPage 4 of 7 Ground water elevation data collected in the hydrologic unit 1 and 2 (water table to 65 feet bsg) in the area monitoring wells MW-1,MW-3, MW-4,MW-5A,MW-6A,MW-7A and MW-8A ranged from 33 82 to 35 60 feet below mean sea level (msl) The ground water elevation for well MW-2, 36 51 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 The top of the ground water table occurred within the screened intervals of the wells The ground water elevation decreased 4 8 feet at the site over the last quarter Ground water was determined to be flowing to the northwest with a hydraulic gradient of 0 0037 The ground water elevation contours for hydrologic units 1 and 2 are depicted on Figure 3 iGround water elevation data collected in the hydrologic unit 4 (90 to 100 feet bsg) in the area monitoring wells MW-513, MW-613, MW-713 and MW-813 ranged from 35 47 to 35 70 feet below i msl Ground water was determined to be flowing toward the south with a hydraulic gradient of 0 002 The ground water contours for hydrologic unit 4 are depicted on Figure 4 iGroundwater elevation data collected in the hydrologic unit 5 upper(125 to 135 feet bsg)in the area monitoring wells MW-5C, MW-6C, MW-7C and MW-8C ranged from 35 21 to 35 98 feet below i • msl Ground water was determined to be flowing toward the northwest with a hydraulic gradient of 0 009 The ground water contours for hydrologic unit 5 are depicted on Figure 5 i Ground water elevation data collected in the hydrologic unit 5 lower(150 to 160 feet bsg)in the area monitoring wells MW-5D,MW-7D and MW-8D ranged from 35 39 to 3 5 86 feet below msl Ground water was determined to be flowing toward the northwest with a hydraulic gradient of 0 005 The iground water contours for hydrologic unit 5 are depicted on Figure 6 Ground water elevation data collected in the hydrologic unit 6 (175 to 185 feet bsg) in the area i monitoring wells MW-5E, MW-6E, MW-7E and MW-8E ranged from 35 45 to 36 01 feet below msl Ground water was determined to be flowing toward the northwest with a hydraulic gradient of 0 005 The ground water contours for hydrologic unit 6 are depicted on Figure 7 i 3 2 ANALYTICAL RESULTS OF GROUND WATER SAMPLE ANALYSIS iTwenty-four water samples were analyzed by MAI for the chemical constituents referenced in Section 2 3 The following is a summary of the analytical results for each hydrologic unit I i iAdvanced GeoEnvi ron mental,Inc i
