t <br /> Mr. Kyle Christie Project 0805-159.01 <br /> January 23, 1996 <br /> Page 2 <br /> were observed. Soil generated from the trenches was stockpiled on and covered with <br /> plastic. On November 7, 1995, Dillard Environmental Services transported the stockpiled <br /> soil to BFI, Inc.'s, landfill in Livermore, California. <br /> SOIL ANALYSES AND RESULTS <br /> i <br /> Soil samples were submitted to Sequoia Analytical in Sacramento, California, a state- <br /> certified laboratory, for analysis of total petroleum hydrocarbons as gasoline (TPHG) <br /> using Environmental Protection Agency (EPA) Method 8015; and benzene, toluene, i <br /> ethylbenzene, and total xylenes (BTEX) using EPA Method 8020. In addition, the soil <br /> composite sample SP-1 collected from the stockpiled soil was analyzed for reactivity, <br /> corrosivity, ignitability, and total lead. <br /> TPHG and BTEX were below laboratory detection limits for the nine soil' samples <br /> collected from the product line trenches. Toluene and total xylenes were detected in <br /> stockpile sample SP-1 at concentrations of 0.0057 and 0.024 parts per million (ppm), <br /> respectively. Total lead was detected at 10 ppm. Soil analytical results are summarized in <br /> Table 1. Certified analytical reports and chain-of-custody records are presented in <br /> Appendix B. <br /> CONCLUSIONS j <br /> The. nine soil samples collected from beneath the product line trenches were below <br /> laboratory detection limits for TPHG and BTEX. Based on these analytical results, no <br /> further excavation of soil associated with the product line removal and replacement <br /> activities is warranted. <br /> DOCUMENT DISTRIBUTION <br /> We recommend copies of this report be distributed to the following: <br /> Jerry Yoshioka <br /> San Joaquin County Public Health Services <br /> Environmental Health Division 4 <br /> P.O.
