TPH-D = total petroleum hydrocarbons quantified as diesel. TRPH = total recoverable <br /> petroleum hydrocarbons.TPH-M=total petroleum hydrocarbons quantified as motor oil. TPH-D and TPH-M analyzed using EPA Method 8015 <br /> (modified). TRPH analyzed using EPA Method 418.1. BTEX analyzed using EPA Method 8020. <br /> 3 <br /> Sample locations are shown on Figure 2. Sample depths are for the bottom of the sample,in feet below ground surface. <br /> 4 GC characterization indicated the petroleum hydrocarbon in this sample to be a heavily degraded material with a boiling range similar to diesel <br /> #2 and a lesser amount of heavy material. The chromatogram for this sample was similar to the chromatograms for samples from the Dividend <br /> property. A TPH concentration of 20,000 mg/kg was measured using thin layer chromatography(TLC). TLC is a screening analysis and these <br /> analytical results are not directly comparable to TPH concentrations derived from EPA Methods 418.1 or 8015(modified). <br /> no=not analyzed. <br /> <=concentration less than the method detection limit shown. <br /> 7 data not available. <br /> [1p]C70A'rAUCCUMENnCHEVRONU499.10.DOC <br />
