Tab e 1 <br /> I - <br /> Groundwater Monitoring and Analytical Resifts <br /> Former Chevron Service Station#9-8612 <br /> 575 Grant Line Road <br /> Tracy,California <br /> EXPLANATIONS- <br /> Groundwater monitoring data and laboratory analytical results prior to.lune 26,2000,were compiled from reports prepared by Blaine Tech Services,Inc <br /> TOC=Top of Casing TPH-D=Total Petroleum Hydrocarbons as Diesel TOG=Total Oil and Grease <br /> (ft)=Feet B=Benzene (ppb)=Parts per billion <br /> DTW=Depth to Water T=Toluene NP=No Purge <br /> GWE=Groundwater Elevation E=Ethylbenzene =Not Memured/Not Analysed <br /> (msl)=Mean sea level X=Xylenes <br /> TPH-G=Total Petroleum Hydrocarbons as Gasoline MTBE=Methyl tertiary butyl ether <br /> * The survey was completed on November 16,2000,by Virgil Chavez Land Surveying The elevations are based on the data provided by G-R Inc,holding <br /> TOC of MW-i Measurements taken at approximate north side of top of box top of casings were marked at location of measurements <br /> 1 Chromatogram pattern indicates an unidentified hydrocarbon <br /> 2 EPA Method 5520 <br /> 1 Laboratory report indicates gasoline C6-C12 <br /> Laboratory report indicates unidentified hydrocarbons C10-C24 <br /> s Laboratory report indicates unidentified hydrocarbons C9-C24 <br /> F Laboratory report indicates unidentified hydrocarbons<C16 <br /> 7 MTBE by EPA Method 8260 <br /> s Laboratory report indicates discrete peaks <br /> 9 Laboratory report indicates unidentified hydrocarbons>C16 <br /> 10 Laboratory report indicates hydrocarbon pattern present in the requested fuel quantitation range but does not resemble the pattern of the <br /> requested fuel <br /> Laboratory report indicates gasoline <br /> i2 Laboratory report indicates Toluene did not confirm via GCMS <br /> 11 Laboratory report indicates this sample was originally analyzed within holding time Re-analysis for confirmation or dilution was performed past the <br /> recommended holding time <br /> 14 MTBE by EPA Method 8260 was analyzed outside recommended holding time <br /> is Due to laboratory error the TPH-D samples for MW-3 and MW-4 were composited The corresponding result rs reported as MW-1 <br /> 9-8612 x151#386855 7 As of f17h l/n1 <br />
