TABLE 2 <br /> GROUNDWATER ANALYTICAL RESULTS <br /> FOR OXYGENATES AND ADDITIONAL COMPOUNDS <br /> ARCO Service Station No. 5469 <br /> 130 South Wilson Way, Stockton, California <br /> USEPA USEPA <br /> Method 8260 Method 8015 (M) <br /> Well TBA MTBE DIPE ETBE TAME 1,2-DCA EDB Ethanol Methanol QA/QC <br /> Number Date µ Review <br /> NOTES: <br /> µg'L-micrograms per liter. TBA-Tertiary butyl alcohol QA/QC Review: <br /> - Below detection limit for analytical methods used. MTBE=Methyl tertiary butyl ether. A=Data accepted without qualification <br /> NA=Not Analyzed DIPS=Di-isopropyl ether. J=Data accepted with qualification <br /> USEPA -U.S.Environmental Protection Agency. ETBE=Ethyl tertiary butyl ether. R=Data rejected <br /> TAME-Tertiary amyl methyl ether. <br /> 111 This sample was analyzed outside of EPA recommended hold time. 1,2-DCA=1,2-Dichloroethane <br /> [21 The value reported exceeds the calibration curve but not the linear range. EBB=Ethylene dibromide <br /> [31 The reporting limits for this sample have been raised due to the high level of a target compound. <br /> [41 The reporting limits for this sample have been raised due to the high levels of non-target interferents. <br /> [51 The continuing calibration standard was outside of the acceptance criteria. <br /> [61 There was insufficient preservative to reduce the sample pH to less than 2. no sample was analyzed within 14 days of sampling,but beyond the 7 days recommended for Benzene,Toluene,and$thylbenzene. <br /> 5TkAT05 <br /> Arco_5469_Quarterly_Data <br /> 9 of 9 � <br />
