(Condor) on June 22, 2005, at the Canepa' s Car Wash site. The equipment began <br /> operation and discharge on November 1 , 2004. Report attachments include laboratory analytical reports <br /> for the June sampling (Attachment A). <br /> The final discharge point was sampled at the above-referenced site to evaluate treated water quality being <br /> discharged to the sanitary sewer system after treatment through an air-stripper/activated carbon series. <br /> Laboratory analytical results from the treated groundwater sample will be used to monitor and verify <br /> groundwater discharge quality and operational efficiency of the treatment equipment. <br /> OPERATIONAL PARAMETERS <br /> Table 1 : Flow and Lower Explosive Limit Field Parameters <br /> Temp.
