This data tends to indicate that the <br /> first analysis of the production well discharge may have <br /> been a false positive. This is not an uncommon <br /> occurrence especially when analyses are being performed <br /> at extremely low detection limits. <br /> The presence of benzene at 0.0045 ppm in MW-3 does <br /> Indicate a possible migration of the soluable gasoline <br /> constituent in the shallow ground water from the <br /> excavation area towards the production well. Although <br /> such migration appears to be perpendicular to the <br /> measured .flow gradient it is important to note that <br /> f, variations in flow direction are likely. The variation, '� <br /> �- in our opinion, would most likely be influenced by the /}till <br /> i \, <br /> ti. adjacent surface impoundments. Regardless of the <br /> i <br /> r, (presence of the benzene in MW-3, the likelihood that the <br /> r chemical compounds could be drawn into the production <br /> •well is not suggested by the pump test. In addition, <br /> the pumping rate and volume of production water make it <br /> highly unlikely that a compound detected at 0.0045 ppm <br /> d � LVV <br /> In MW-3 under static conditions would be detectable at <br /> 0.0007 ppm in the production well. <br /> Theda-ta--does—not- support—the---need---to---cont-ince— — — - <br /> abandonment of the production well use.
