(except where noted)and analyzed by Friedman and Bruya,Inc. for total petroleum hydrocarbons <br /> (TPH)quantified as gasoline(C6-C12;TPHg),TPH quantified diesel(Clo-C24i TPHd),and TPH quantified as crude oil (CIO-C36;TPHc)by EPA Method <br /> 8015M; for benzene,toluene,ethylbenzene,and total xylenes(BTEX)and methyl tertiary butyl ether(MTBE)using EPA Method 826013;and for polynuclear <br /> aromatic hydro-carbons(PAHs)using EPA Method 8270SIM. <br /> 2 Only detected PAHs are shown: Nph=Naphthalene,Acn=Acenaphthene,Flr=Fluorene,Phn=Phenanthrene, <br /> Flt=Fluoranthene,Pyr=Pyrene,Chr=Chrysene,and B(a)A=Benzo(a)anthracene. <br /> 3 <br /> Samples were collected by Earth Systems Consultants and analyzed by Chromalab,Inc.,for Total Extractable Petroleum Hydrocarbons(TEPH)quantified as <br /> diesel,motor oil,and crude oil using EPA Method 8015M, and BTEX using EPA Method 8020; and by Friedman and Bruya,Inc., for PAHs using EPA Method <br /> 8270SIM. No TEPH quantified as motor oil was detected. <br /> 4 NA=Not analyzed. <br /> is\doc_safe\6000s\6115.007\dec2000report\table 1-2-3.x1s Page 2 of 4 <br />
