Copies of the Certiried Analytical <br /> Report and sample Chain-of-Custody records are attached. <br /> RECOML KENDATIONS <br /> During communications on March 25, 1999 beiween E 1 and Mr. Steve Sasson of the SJCEFiD, Mr_ <br /> Sassoti stated that if no oxygenates were detected 6y EPA Method 826013, the excavations could be <br /> backfilled and dispenser island re-construction could c mmence. Mr. Sasson also stated that if lore <br /> concentrations ol-oxygenates existed in confirmation samples, the excavation could be lined with plastic <br /> to prevent potential [caching and vertical migration of residual PFICs; after, this mitigation step was <br /> implemented, the excavations could then be bac;kfillrxi_ <br /> Krazan recommends that a copy of this report be submitti d to the following: <br /> Mr. Steve Sasson <br /> San Joaquin County Environmental 1-1calth Divis on <br /> 304 Cast Weber Street <br /> Stockton, Califurma 95202 <br /> LIMITATIONS <br /> The findings of this report weree based upuc:the results a our field and laboratory investigations,coupled <br /> with the interpretation of subsurface conditions associated with the dispenser island excavation. <br /> Therefore, the data are accurate only to the degree ii nplied by review of the data obtained and by <br /> prufessional interpretation. <br /> KRAZAN&ASSOCIATES,INC. <br /> ores Serving the test rn United State's <br /> .�a=�enao.nou <br />
