FINDINGS <br />' Ground water elevation, flow direction and gradient were determined from field data collected on } <br /> 29 June and 13 September 2601, the contaminant impact to ground water was assessed from the <br />' laboratory analytical data- <br /> 1 <br />' 4 1 GROUND WATER GRADIENT AND FLOW DIRECTION <br /> The relative elevation of groundwater in each well was calculated by subtracting the depth to ground <br /> lie water from the surveyed well head elevations (Table 1) Depths to ground water during the <br /> June 2001 monitoring event ranged from 24 51 feet to 23 45 feet below the tops of the well casings <br /> Ground water elevations at the site ranged from-13 21 feet in MW-3B to -13 56 in MW-1 relative <br /> to mean sea level (msl) The ground water gradient was calculated to be 0 003 ft/ft with a flow ✓ <br /> direction toward the west northwest(Figure 3) During the September 2001 monitoring event depths <br />' to ground water ranged from 25 63 feet to 24 54 feet below the tops of the-well casings Ground <br /> water elevations at the site ranged from-14 32 feet in MW-3B to -14 89 in MW-3A relative to msl <br /> The ground water gradient was calculated to be 0 0015 ft/ft with a flow direction toward the <br />' southwest (Figure 4) <br />' 4 2 ANALYTICAL RESULTS OF GROUND WATER SAMPLES <br /> t <br /> Monitoring wells MW-1, MW-2A, MW-2B and MW-3A were sampled on 13 S eptember 2001 The <br />' analytical results of the ground water samples were as follows <br /> • TPH-g was detected in ground water samples collected from monitoring'-wells MW-1, <br />' MW-2A,MW-213 and MW-3A TPH-g concentrations ranged from400 micrograms per liter <br /> (gg/1)m MW-2A to 220,000 gg/1 in MW-1 Benzene was detected in samples collected from <br /> wells MW-1, MW-2A, MW-2B and MW-3A at concentrations of 30,000 gg/l, 11 µg/l, x <br />' 16,000 µg/l and 17,000 gg/l, respectively Toluene, ethylbenzene and total Xylenes were <br /> . detected in the ground water samples collected from monitoring wells MW-1, MW-2A, <br />' MW-2B and MW-3A The highest concentrations were detected in the sample collected <br /> Advanced GeoEnvirownental,Inc <br /> rl 11 <br /> 1 <br />
