File No. NFE-4533-01 _ Doc. No. 9908-086 <br /> August 24, 1999 <br /> diesel, motor oil, and crude oil using EPA modified method 8015 and benzene, toluene, <br /> ethylbenzene, and total xylenes (BTEX) using EPA method 8020. Samples were also sent by <br /> overnight delivery, under chain of custody protocol, to Friedman and Bruya (F&B) in Seattle, <br /> Washington (FLAP #1727) and analyzed'for polynuclear.aromatic hydrocarbons (FNAs) using <br /> EPA method 8270 SIM. (Selected ion monitoring). <br /> Analytical Results <br /> ' The soil sample collected at a depth of 9 feet bgs from E137 contained the,following: <br /> ° 3,400 parts per million (ppm)TEPH as crude oil (based of the response factor of diesel) <br /> ° 1.6 ppm toluene <br /> ° 0.70 ppm total xylenes <br /> ° 0.540 ppm acenaphthene - <br /> L ° 0.130PP m benz(a)anthracene <br /> 0.540 ppm chrysene _ <br /> ° 0.071 ppm fluoranthene <br /> ° 3.9 ppm fluorene <br /> ° 5.1 ppm phenanthrene <br /> 0.270 PPm Pyrene <br /> All other analytes were below detection limits. However, the &etection-limits for the extractable <br /> hydrocarbons and PNAs were raised due to high levels of material, as stated by the laboratory. In <br /> addition, the PNAs analysis was run twice' with different dilution!levels: Table 1 summarizes the <br /> analytical results, and specifies which results are from the analysis run with the higher dilution <br /> Clevel. <br /> The samples collected at a depth of 14.5 feet bgs from EB9 contained the-following: <br /> 4,300 ppm TEPH as crude oil (based on the response factor of diesel) <br /> C ° 7.5 ppm toluene <br /> I <br /> ° 3.4 ppm total xylenes - <br /> ° 0.160 ppm acenaphthene " <br /> ° 0.035 ppm benz(a)anthracene <br /> ° 0.140 ppm chrysene <br /> 0.029 ppm fluoranthene , <br /> r ° 0.490 ppm fluorene <br /> y ° 0.720PP m phenanthrene <br /> ° 0.093 ppm Pyrene <br /> CAll other analytes were below detection limits. However,, the detection limits for the'hydrocarbons <br /> were raised due to high levels of material. In addition, the PNAs analysis was run twice with <br /> different dilution levels.
