The <br /> = llowing discussion took place: <br /> I . Off-post Domestic Well Sampling Results <br /> A. Cembrano Well Contamination <br /> Sharpe reiterated their position that they do not feel <br /> that any of the pollution in the Cembrano well (also <br /> known as H&M Transport ) is from the Depot . Sharpe <br /> believes that this well is being contaminated from a <br /> rinsewater pond used at the Cembrano site. Joe welsh <br /> Of USATHMA, consultants for Sharpe, also stated that <br /> ground water flow directions would not allow pollution <br /> to move from the Depot to the Cembrano well . Since <br /> confirmation sampling of this well by both Sharpe and <br /> SEB has not detected pollution above State Action <br /> Levels Mr. Welsh feels that the well is "clean" . <br /> Gary Reents reported that he and Erik Friedrich of <br /> Sharpe had investigated the Cembrano residence and <br /> rinsewater pond on 12 September 1984 . Mr. Reents <br /> stated that the pond, which was constructed in 1980, <br /> is approximately 100 yards downgradient of the <br /> Cembrano well which would lessen the probability for <br /> pond contaminants to enter the well. The pond could <br /> not affect any of the other off-post wells that have <br /> been sampled. <br /> Mr . Reents also reported that TSCD had sampled the <br /> pond in June 1982 and analyses for solvents were <br /> negative. The State will resample the pond to confirm <br /> these results. <br /> I <br />
