27 May 1997 <br /> AGE Project No. 95-0118 <br /> Page 2 of 4 <br /> BTE&X), and <br /> EPA method 8260m for methyl-tert-butyl ether(MTBE)and other oxygenated fuel additives, <br /> including tertiary butyl alcohol (TBA), di-isopropyl ether (DIPE), ethyl tertiary butyl ether <br /> (ETBE) and tertiary amyl methyl ether(TAME) and other volatile organic compounds. <br /> 3.0. FINDINGS <br /> 1 3.1. RELATIVE GROUND WATER ELEVATION AND GRADIENT <br /> The relative ground water elevation in each well was calculated by subtracting the ground water <br /> =; depth from the surveyed relative casing elevation. The depth to ground water and the relative ground <br /> water elevations are summarized in Table 1 - Ground Water Elevation Data. <br /> During the February 1998 sampling event,the depth to ground water from the casing tops at the site <br /> ranged from 35.04 to 36.50.feet. Between October 1997 and February 1998 the average depth to <br /> ground water decreased an average 2 feet, that is, ground water elevation has risen approximately <br /> r,; = 2 feet. <br /> During this monitoring event the ground water flow was convergent from the northwest and <br /> =# southeast toward MW-3,and was divergent away from MW-3 towards southwest and north east. The <br /> steepest gradient measured in the area was estimated to be 0.0089 ft/ft. Relative ground water <br /> elevation contours are illustrated in Figure 3 -Relative Ground Water Elei,ation. <br /> 3.2. ANALYTICAL RESULTS OF GROUND WATER SAMPLES <br /> Water samples from monitoring wells MW-2 MW-3 and air-sparging wells VW-1 and VW-2 <br /> contained TPH-g at concentrations of 9;100 parts per billion(ppb,reported as micrograms per liter), <br /> 10,000 ppb, 24,000 ppb and 93ppb, respectively. The same samples contained benzene at <br /> concentrations of 320 ppb, 160 ppb, 1,100 ppb and I.6 ppb. Other,BTE&X compounds were <br /> detected at concentration as great as 3,300 ppb (xylene). <br /> J. The water sample collected from well MW-1 contained benzene and xylene at concentrations of 0.70 <br /> ppb and 1.1 ppb. The water samples collected from MW-4, MW-5 and MW-6 did not contain <br /> detectable concentrations of TPH-g, BTE&X compounds or oxygenated compounds. <br /> AdraucedGeoEnvironmenfal,Inc. <br /> I <br />
