Custody document to WESTON Analytics' Stockton, California <br /> laboratory. The samples were analyzed for the following: <br /> o Total petroleum hydrocarbons (light) - EPA Method 8015. <br /> o Total petroleum hydrocarbons (heavy) - EPA Method 8015. <br /> Modified. <br /> o Total halogenated volatile organi--s - EPA Method 8010. <br /> 0 Benzene, Xylene, Toluene and Ethyl.3enzene (BXT&E) - EPA Method <br /> 8020. <br /> In addition, one of the soil samples collected was analyzed for <br /> PCB's (EPA Method 8080) . <br /> Analytical results for these samples are found in Appendix B and <br /> are summarized in Table 2. <br /> TABLE 2 <br /> Compounds (mg/]:g) <br /> EPA Method 8010 <br /> (Detected Compounds Only) TPH <br /> San 1e I.D. Dichloromethane 13TX&E Light & Heavy PCB's <br /> TNWA 0.38 u u <br /> TNEB 0.38 u u u <br /> note u indicates all compounds were below laboratory <br /> detection limits. <br /> The results indicate that all compounds were nondetectable in the <br /> s ;w soil samples with the exception of Dichloromethane.. The analysis <br /> indicates that it is unlikely there was any leakage of hydrocarbon <br /> related compounds in the area of the tank. <br /> It should also be noted that the low concentration of F,ichlora- <br /> methane (0.38 mg/Kg) probably represents laboratory contamination. <br /> This compound is a common laboratory solvent and was present in <br /> both the Laboratory Water Blank and in the Methanol Blank. <br /> 15 - <br />
