r <br /> r <br /> November 2000, using an electromc water level indicator Grab samples were collected from <br /> soil borings B-6 and B-7 The results are found in Table 5 and in Figure 8 <br /> r <br /> r 3.5 Laboratory Analysis <br /> r As described below, soil and groundwater samples collected were submitted under chain of <br /> r custody to a state certified laboratory, Precision Enviro-Tech Analytical Laboratory in Stockton, <br /> r <br /> CA, for analysis <br /> r <br /> 3.5 1 Soil Sample Analysis <br /> Four (4) soil samples from each soil boring were analyzed with at least two (2) of these soil <br /> r samples being from the saturated zone All soil samples were extracted using EPA method 5030 <br /> r <br /> r After extraction, the soil samples were analyzed for total petroleum hydrocarbons as diesel, oil <br /> r and gasoline (TPH-g, TPH-d and TPH-o) by EPA Method 8015 as well as analyzed for benzene, <br /> r toluene, ethylbenzene and total xylenes (BTEX) by EPA Method 8260, and Methyl t-Butyl Ether <br /> r (MTBE)/oxygenates [dibromomethane (EDB), di-isopropyl ether (DIPE), ethyl-t-butyl ether <br /> (ETBE), tert-amyl methyl ether (TAME), t-butanol (TBA)] by EPA Method 8260 The soil <br /> r samples collected from MW-4 were also analyzed for methanol, ethanol and 1,2-dichoroethane <br /> (DCA) by EPA Method 8260 The results of these analyses are presented in Table 1 and in text <br /> of Section 4 2 <br /> r <br /> 3.5.2. Groundwater Sample Analyses <br /> r The grab samples collected from soil borings B-6 and B-7 were analyzed for total petroleum <br /> r hydrocarbons as diesel, oil and gasoline (TPH-g, TPH-d and TPH-o) by EPA Method 8015 as <br /> r <br />! well as for benzene, toluene, ethylbenzene and total xylenes (BTEX) by EPA Method 8260, and <br /> r Methyl tert-Butyl Ether (MTBE)/oxygenates [di-isopropyl ether (DIPE), ethyl-t-butyl ether <br /> r (ETBE), tert-amyl methyl ether (TAME), t-butanol (TBA)] by EPA Method 8260 Results of <br /> r these analyses are presented in Table 2 and in the text of Section 4 3 <br /> r <br />• 3.6 Floating Oil <br /> r <br /> Floating oil found in MW-2 was removed on two separate occasions throughout the third quarter <br /> The amounts removed are as follows <br /> Environeering,Inc Project No 00-01108 g <br /> r <br /> r <br /> r <br />
