ji <br /> I.-H. KLE INFELDER & ASSOCIATES <br /> J SAMPLE ANALYSES <br /> Eight soil samples were submitted for chemical analyses: to Chemwest <br /> Analytical Laboratorie's under chain-of-custody procedures .' on May i� 14, <br /> 1987. The samples were analyzed for total petroleurp hydrocarbon6 by <br /> GC-FID extraction and for benzene, toluene, and' <br /> xylene by EPA method 8020. <br /> Analytical results were received on the afternoon of May�120'. 1987. These <br /> results are summarized on Table 3. The results of analysis of samples <br /> P <br /> SS-03, SS-04, SS-06, and SS-07 (collected from the excavation) show no <br /> detectable levels of benzene, toluene or xylenes, and Aon-detectablie or <br /> very low levels of total petroleum hydrocarbons. <br /> Several samples collected from the soil pile show <br /> levels of total <br /> petroleum hydrocarbons of potential concern. <br /> �j <br /> These results appear to indicate that the contaminated soil has been <br /> -excavated to non-detectable or low levels. The soil pile does contain <br /> hydrocarbon constituents at levels of potential concern. <br /> If you have any questions about the sample results, pleas!'e contact myself <br /> r! or Kent, Zenobia.
