The sampler were driven continuously by a wire line hammer. <br /> The laboratory samples did not have head space and were immediately sealed in their <br /> liners using TeflonO lined plastic caps. The remaining sample were removed from their <br /> liner to be used as an aide to the on-site specialist in logging the material at that depth. <br />' Soil samples collected for analysis were analyzed using EPA method 8015 for Total <br /> Petroleum Hydrocarbons as Gasoline (TPH-G), EPA method 8020 for Methyl tertiary <br />' Butyl Ether (MTBE) and Benzene (B), Toluene (T), Ethyl Benzene (E), and Xylenes (X) <br /> compounds, and EPA Method 3550/LUFT for Total Petroleum Hydrocarbons as Diesel <br /> (TPH-D). MTBE was also analyzed by EPA method 8260 to confirm the presence or <br /> ' absence of that contaminate. Analyses were conducted by California Laboratories, Inc. a <br /> State certified laboratory. All samples were recorded on a Chain of Custody and placed in <br /> ' an Ice Chest with Blue Ice@ for transport to the lab. <br /> 4.0 Analytical Results <br /> 1 <br /> Soil Analytical Results-MTBE <br /> ' The soil sample analysis indicated that MTBE contamination is not present in any of the <br /> soil samples collected from this site. The detection limits set for MTBE by EPA method <br /> ' 8020 was between 25 and 250 ug/Kg. Therefore, MTBE was further analyzed using EPA <br /> method 8260 due to the elevated detection limits set using EPA method 8020. This was <br /> requested to provide accurate information regarding MTBE levels in the soil at this site. <br /> ' Three soil samples were chosen for analysis by this method, B-3-15, B-3-30, and B-3-55 <br /> (deep boring in the vicinity of former tank area). The results from this test indicated that <br /> MTBE was not present in these soil samples. A complete tabular summary of the <br /> analytical data can be found in Table 1 of this report. Appendix C contains the laboratory <br /> analytical data, Chain of Custody Reports, and QA/QC documents. <br /> Soil Analytical Results: Boring B-I <br /> ' The laboratory analytical results for Boring 13-1 are presented below. MTBE was not <br /> present in Boring B-1. <br /> 03NOV99 <br /> B-1-10 ND ND ND ND ND ND ND <br /> B-1-15 ND ND ND ND ND ND ND <br /> B-1-20 4.5.:''..... .
