This <br /> may indicate a bias for the sample that was spiked. Since the LCS recoveries were within constrol <br /> limits, no data are flagged. <br /> 37=Matrix Spike/Matrix Spike Duplicate results were affected by the analyte concentrations already <br /> present in the un-spiked sample. <br /> 38=Wallace-Kuhl did not sample due to ongoing negotiations with the City and the Regional Board. <br /> 39=Dimethyl Phthalate detected at 0.013 mg/I. <br /> 40=Dimethyl Phthalate detected at 0.022 mg/I. <br /> 41 =Benzoic Acid detected at 4.1 mg/I. <br /> 42=Wells destroyed in November 2008 as part of the Unocal excavation activities by Treadwell and Rollo. <br /> 43=2,6-Dinitrotoluene detected at 0.018 mg/I. <br /> Stantec <br /> I:\Tidewater\TW Stockton(Parcel 2A-0415)\Tables\QMR Tables\2010\4Q10\20101117-Parcel2A(Tables 4,5,6,7)Historical GW Tables 4Q10.xls Page 52 of 52 <br />
