17-7-, <br /> 1 H KLEINFELDER & ASSOCIATES <br /> SAMPLE ANALYSES <br /> �1 Eight soil samples were submitted for chemical analyses to Chemwest <br /> Analytical Laboratories under chain-of-custody procedures on May 14, <br />'i 1987. The samples were analyzed for total petroleum hydrocarbons by <br /> GC-FID extraction and for benzene, toluene, and xylene by EPA method 8020. <br /> Analytical results were received on the afternoon of May 20, 1987. These <br />' results are summarized on Table 3. The results of analysis of samples <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 non-detectable or <br /> very low levels of total petroleum hydrocarbons. <br /> Several samples collected from the soil pile show levels of total <br /> petroleum hydrocarbons of potential concern. <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, please contact myself <br /> E or Kent Zenobia.
