' 01 December 2004 AGE-NC Project No 97-0333 ' Page 7of11 , 3 5 1 1 First Zone Aquifer Ground water elevation data collected in the First Zone Aquifer (15 to 47 feet bsg) inferred an inward ground water flow,towards a ground water depression in the area of wells EW-1,MW-6 and ' MW-7A (Figure 4), ground water gradients were approximately 0 009 ft/ft or less within the depression 3 5 1 2 Second Zone Aquifer ' Ground water elevation data collected in the Second Zone Aquifer (58 to 92 feet bsg) inferred a northwest ground water flow direction Ground water gradients were approximately 0 001 ft/ft or ' less near the site (Figure 5) ' 3 5 13 Third Zone Aquifer Ground water elevation data collected in the Third Zone Aquifer(102 to 120 feet bsg) inferred a ' northwest ground water flow direction Ground water gradients were approximately 0 001 ft/ft or less near the site (Figure 6) 3 5 1 4 Primary Aquifer Zone ' Ground water elevation data collected in the Primary Aquifer Zone(128 to 150 feet bsg)inferred a northwest ground water flow direction Ground water gradients were approximately 0 001 ft/ft or ' less near the site (Figure 7) ' 3 5 2 Laboratory Results of Ground Water Samples During the June 2004 sampling event, TPH-g was detected in twenty-two water samples collected ' from wells MW-1 through MW-4,MW-7(B-E),MW-8(B-D),MW-9B,MW-10(B-D),MW-11 (C and D), MW-12 (A-D) and MW-13C at concentrations as high as 15,000 gg/l (MW-2) ' Various BTEX constituents were detected in seven water samples collected from wells MW-1 through MW-4 and MW-7(A-C)at maximum concentrations of 200µg/1 benzene,980µg/1 toluene, 270 µg/l ethylbenzene and 1,500 µg/l xylenes from well MW-2 ' Advanced GeoEnvironmental,Inc
