Matrix Spike/Matrix Spike Duplicate results for Chlorobenzene were outside of control limits. Clayton 3=Phenol detected 0.057 moll. This may Indicate a bias for the sample that was spiked. Since the LCS recoveries were within control limits,no data are flagged. Phenol detected at 0.037 moll. s=Phenol detected at 0.025 moll. 37=Matrix Spike/Matrix Spike Duplicate results were affected by the analyte concentrations € a=Surrogate spike compound(p-Terphenyi-d14)was out of control due to matrix interference. The already present in the un-spiked sample. associated method blank surrogate spike compound was in control and,therefore,the sample data "=Wallace-Kuhl did not sample due to ongoing negotiations with the City and the Regional Board, was reported without further clarification. 39=Dimethyl Phthalate detected at 0.013 mgt€. 7=Surrogate spike compound(2-Fluorobiphenyl)was out of control due to matrix interference. The 40=Dimethyl Phthalate detected at 0.022 moll. associated method blank surrogate spike compound was in control and,therefore,the sample data 41=Benzoic Acid detected at 4.1 moll. was reported without further clarification. "=Wells destroyed in November 2008 as part of the Unocal excavation activities by Treadwell and Rollo. e=Surrogate spike compound(Phenol-d6)was out of control due to matrix interference. The "W 2,6-Dinitrotoluene detected at 0.018 mg/l. associated method blank surrogate spike compound was in control and,therefore,the sample data 44=Phenol detected at 0.042 moll. was reported without further clarification. 45=Phenol detected at 0.013 mgfl. '=Samples collected by Clayton Group Services. 48=SVOC sample bottles arrived broken to the laboratory;therefore,SVOCs were not analyzed. 10=Phenol detected at 0.089 moll. 47=Hexachloroethane detected at 0.02.4 moil. Phenol detected at 0.014 moll. 72=Bis(2-Chtoroethyl)Ether detected at 0.024 moll. "=Phenol detected at 0.012 mg/l. 14=Phenol detected at 0.180 moll. '6=Phenol detected at 0.025 moil. s=Date samp€e was prepared. 77=The analyte concentration was reported from analysis of the diluted sample. 13=Dilution factor of 10. 18=Phenol detected at 0.057 mg/l. 20=Phenol detected at 0.087 mg/l. 21=Phenol detected at 0.024 mg/l. "=The relative standard deviation of the calibration curve response factors exceeds the control limit for the analyte 2-Naphthylamine. 23=The relative standard deviation of the calibration curve response factors exceeds the control limit for the anal 24_The Continuing Calibration Verification(CCV)recovery is not within established control limits for the analyte 25=The Continuing Calibration Verification(CCV)recovery is not within established control limits for the analyte N-Nitrosodimethylamine. 26=Phenol detected at 0.018 moll. 27 M Collected by Wa€lace Kuhl. 23=Phenol detected at 0.039 moll. 29=Phenol detected at 0.034 moll. 30=Phenol detected at 0.045 moll. 35=Di-n-Octyl Phthalate detected at 0.11 moll. 32 M Dl-n-Octyl Phthalate detected at 0.022 moll. 33=Phenol detected at 0.016 mgll, 34=4-Chlorophenyl-phenyl ether detected at 0.012 mg/I. 35=Phenol detected at 0.011 mgll.
