Refer to Plate 3 for area specifics. <br /> 3.0 PROJECT HISTORY <br /> ? - The underground fuel storage tanks were excavated and removed from the subject <br /> 1 <br /> property in September 1983. Soil samples were obtained from beneath the underground <br /> } tanks and associated product piping at the time of the tank removals by others. The <br /> samples obtained were submitted to an analytical laboratory for chemical analysis. <br /> l The results of the chemical analysis revealed low petroleum contamination on most of <br /> the samples. Test results revealed contamination near the south west corner of the l <br /> tank excavation of 3800 ppm TPH, 160 ppm toluene, 77 ppm ethylbenzene, 1430 ppm xylene <br /> and non-detected benzene In addition,the samples from below product lines near the <br /> f ; ; southwest corner of the tank pit excavation revealed 720 ppm TPH, 10 ppm benzene,62 <br /> m toluene, 19 <br /> f., <br /> pp pprn ethylbenzene, and 100 ppm xylene. Tine waste oil tank removal <br /> sampling near the north side of the gasoline tank excavat,on also revealed <br /> contamination present with 49 ppm TPH. <br /> 15000-205-344 <br /> V <br /> DAMES ti `ZI]LS3�G <br />
