<br />' 3 2 GROUND WATER TREATMENT RESULTS
<br /> „
<br /> Between 12 November 2004 and 17 March 2005, the pump-and-treat system was operational
<br />' Utilizing a Blue-White Industries F-2000 flow meter, a total flow of 442,213 gallons(totalizer)was
<br /> recorded during the operational period (Table 3) Based on the discharged water recorded on the
<br /> meter,AGE estimated that on an average approximately 2,200 gallons of water were discharged per
<br /> day
<br />' 3 2 1 Laboratory Analysis of Influent Ground Water Samples
<br /> TPH-g and BTEX compounds were detected in the influent samples from wells EW-1, VW-1 and
<br />' VW-3
<br /> • On 15 December 2004 TPH-g was detected in influent sample EW-tat 1,500 micrograms
<br />' per liter(µg/1),BTEX compounds were detected in the sample at 170 µg/1 benzene, 150µg/1
<br /> toluene,54 gg/1 ethylbenzene and 160 µg/1 xylenes and TPH-g was detected in sample VW-

<br /> mixed with VW-3)at 1,300 µg/1, BTEX compounds were detected in the sample at 3 8 µg11
<br /> benzene, 16µg11 toluene,0 69 µg11 ethylbenzene, 1 1 µg/l xylenes,and TPH-g was detected
<br /> in influent sample VW-3 (most likely mixed with VW-1)at 33,000 µg/1,BTEX compounds
<br /> were detected in the sample at 6,200 benzene, 630 µg11 toluene, 7,900 µg/1 ethylbenzene,
<br /> 2,700 µg/1 xylenes
<br /> • On 17 February 2005 TPH-g was detected in influent sample EW-1 at 4,300 µg/I, BTEX
<br /> compounds were detected in the sample at 800 µg/1 benzene, 560 µg/1 toluene, 150 µg/1
<br /> ethylbenzene, 470 µg/1 xylenes, TPH-g was detected in influent sample VW-1 at
<br /> 25,000 µg/1, BTEX compounds were detected in the sample at 5,000 µg/l benzene, 3,900
<br /> µg/I toluene,450µg/1 ethylbenzene,2,400 gg/I xylenes and TPH-g was detected in influent
<br /> sample VW-3 at 240 µg/1, BTEX compounds were detected at 13 µg/1 benzene, 9 2 µg/1
<br /> toluene, 21 µg11 xylenes
<br /> EOn 17 March 2005 TPH-g was detected In influent sample EW-1 at 1,700 Vg/l,
