C A M B R I A <br /> The soil samples were analyzed for total petroleum hydrocarbons as gasoline (TPHg) by EPA <br /> Method 8015 (modified), benzene, toluene, ethylbenzene, xylenes (BTEX by EPA Method <br /> 8020, and fuel oxygenates (MTBE, TAME, DIPE, ETBE, and TBA,) by EPA Method <br /> 8260B. <br /> ANALYTICAL RESULTS <br /> Soil sample results are presented in Table 1 and the attached certified analytical reports <br /> (Appendix A). A summary of the data is presented below. <br /> Soil sample DP-4, collected from native soil beneath the product piping, contained only <br /> 0.130 milligrams per kilogram (mg/kg) of xylenes and 1.630 mg/kg of MTBE. Soil sample <br /> SP, collected from the stockpile, did not contain detectable concentrations of TPHg, BTEX, <br /> or fuel oxygenates. <br /> CLOSING <br /> This service station was previously an active environmental case with the SJCPHS/EHD. On <br /> February 23, 1996, SJCPHS/EHD issued a "no further action" letter, indicating that the <br /> environmental case would be closed. The case was subsequently closed. <br /> During the July 31, 2000 soil sampling event, low levels of xylenes and MTBE were detected <br /> in native soil below the piping leak, and no gasoline constituents were detected in the soil <br /> excavated from around the piping leak. Based on field observations, it appeared that the fuel <br /> leak was contained by the secondary containment system and a release to the environment <br /> did not occur. The detection of xylenes and MTBE in soil sample DP-4 likely represents <br /> residual contaminants from the previous environmental case at this site. <br /> Based on these data, Cambria feels that further investigation related to this piping leak is not <br /> warranted. <br /> 0953 2 <br />
