FIELD WORK <br /> On July 19, 1996, the tank was removed and John N. Alt collected <br /> two soil samples at the locations identified as S-1 and S-2. S- <br /> 1 was approximately 6'h feet below grade and 1 foot into the <br /> native soil below the UST. S-2 was approximately 9 feet below <br /> grade, approximately 22 feet below S-1 and 1 foot above the <br /> groundwater level in the UST excavation. Their location is shown <br /> in Figure 2 . Mr Jerry Yoshioka of the SJCEHD observed the tank <br /> removal and sampling. <br /> A strong hydrocarbon odor was observed during the time that the <br /> soil samples were collected. <br /> The soil samples were collected in clean brass tubes, capped and <br /> sealed, labeled, held in a cooler at approximately 4 degrees <br /> Centigrade and transported under Chain-of Custody (COC) <br /> documentation to be analyzed by a State Certified Laboratory. <br /> The soil samples collected were analyzed for Lead (Pb) , Total <br /> Petroleum Hydrocarbons as Diesel (TPHD) , Total Petroleum <br /> Hydrocarbons as Gasoline (TPHG) and Benzene, Toluene, <br /> Ethylbenzene and Xylene (BTEX) . <br /> ANALYTICAL RESULTS <br /> The results for Lead (Pb) was 15 parts per million (PPM) and 11 <br /> PPM in soil sample S-1 and S-2 respectively. <br /> The analytical results for TPHD, TPHG and BTEX are shown in Table <br /> 1. <br /> TABLE 1 <br /> July 19, 1996 Soil Sample Analysis Results in PPM. <br /> Sample TPHD TPHG B T E X <br /> S-1 870 4,300 7.5 78 82 400 <br /> S-2 110 540 5.9 15 8 . 5 26 <br /> The laboratory data sheets with detection levels and COC <br /> documentation are contained in Appendix A. The results of the <br /> analysis were also faxed directly to Mr. Yoshioka by the <br /> laboratory. <br /> 2 <br />
