The samples were collected as <br /> " directed by a !SJCEHD representative, and according to the methods <br /> presented in Appendix B. The SJCEHD representative requested these <br /> samples ("SS" series) be analyzed by EPA methods 8015/8020, 7421 and <br /> 8010. Method ,8010 is for halogenated volatile organics and does not <br /> analyze for EIB.

Laboratory analytical results for method 8010 are <br /> sum.aarized in !Table 4. <br /> Table 4 <br /> SOIL SAMPLE ANALYTICAL RESULTS/METHOD 8050 <br /> Results Reported In Parts Per Billir^ (PPBI <br /> _ .
