i <br /> 9„ <br /> 4 <br /> I <br /> Em <br /> Mr. Taamas Peltier <br /> September 5, 1990 <br /> Page.. i i <br /> A soil vapor extraction system continues to operate at the site. Over <br /> ,— -- 1200 gallons of gasoline as vapor have been extracted from the soil <br /> I ! beneath the site and destroyed by thermal oxidation since system startup <br /> � in late 1989. The enclosed Work plan has been prepared to provide <br /> s sampling points to evaluate whether deep ground water has been impacted by <br /> the shallow hydrocarbon contamination in sail. <br /> In our opinion, the work described in tho enclosed Work Plan will yield <br /> 4 the data necessary to evaluate the presence of hydrocarbon constituents in <br /> the deep ground water at the site and will reduce potential liability of <br /> downward contaminant migration through the 5 shallow monitoring wells at <br /> the site. <br /> Please do not hesitate to call if you have any 4:estions regarding this <br /> project or work plan. <br /> ' Sincerely, <br /> 1 <br /> ULTRUAR INC. <br /> M <br /> Glenn Dembroff <br /> Marketing Environmental Department <br /> �= Enclosure :Work Plan <br /> t4 - - <br /> I <br /> cc w/ encl: tis.
