<br /> 41 3 2 GROUND WATER TREATMENT RESULTS
<br /> Between 18 August and 12 November 2004'the pump.and-treat system was operational Utilizing1 ;„ '
<br /> r
<br /> a Bfue-White 1i dustnes F-2000 flow meter,a total flow 6f 242,490 gallons(totalizer)was recorded
<br /> dunxig the aforementioned period (Table 3)-Based on the discharged water recorded on the meter, s "`
<br /> WAGE estimated that approximately an average of 2,820 gallons of water were discharged per day
