The associated method blank surrogate spike compound was <br /> in control and,therefore,the sample data was reported without further clarification. <br /> B Analyte was present in the associated method blank. <br /> BA The MS/MSD RPD was out of control due to suspected matrix interference. <br /> BB Spike recovery and RPD control limits do not apply resulting from the parameter concentration in the sample exceeding the spike <br /> concentration by a factor of four or greater. <br /> BU Sample analyzed after holding time expired. <br /> BV Sample received after holding time expired. <br /> DF Reporting limits elevated due to matrix interferences. <br /> E Concentration exceeds the calibration range. <br /> ET Sample was extracted past end of recommended max.holding time. <br /> GE The PDS/PDSD or PES/PESD associated with this batch of samples was out of control due to suspected matrix interference. <br /> HD Chromat.profile inconsistent with pattern(s)of ref.fuel stnds. <br /> HO High concentration matrix spike recovery out of limits <br /> HT Analytical value calculated using results from associated tests. <br /> HX Recovery of the Matrix Spike(MS)or Matrix Spike Duplicate(MSD)compound was out of control due to matrix interference. The <br /> associated LCS was in control. <br /> IL Relative percent difference out of control. <br /> J Analyte was detected at a concentration below the reporting limit and above the laboratory method detection limit. Reported value is <br /> estimated. <br /> JA Analyte positively identified but quantitation is an estimate. <br /> LD Analyte presence was not confirmed by second column or GC/MS analysis. <br /> LP The LCS and/or LCSD recoveries for this analyte were above the upper control limit. The associated sample was non-detected. Therefore, <br /> the sample data was reported without further clarification. <br /> LQ LCS recovery above method control limits. <br /> LR LCS recovery below method control limits. <br /> ND Parameter not detected at the indicated reporting limit. <br /> QO Compound did not meet method-described identification guidelines.Identification was based on additional GC/MS characteristics. <br /> RU LCS Recovery Percentage is within Marginal Exceedance(ME)Control Limit range(+/-4 SD from the mean). <br /> SG A silica gel cleanup procedure was performed. <br /> SN See applicable analysis comment. <br /> Solid-Unless otherwise indicated,solid sample data is reported on a wet weight basis,not corrected for%moisture.All QC results are <br /> reported on a wet weight basis. <br /> Any parameter identified in 40CFR Part 136.3 Table II that is designated as"analyze immediately"with a holding time of—15 minutes <br /> (40CFR-136.3 Table II,footnote 4),is considered a"field"test and the reported results will be qualified as being received outside of the <br /> stated holding time unless received at the laboratory within 15 minutes of the collection time. <br /> A calculated total result(Example:Total Pesticides)is the summation of each component concentration and/or,if"J"flags are reported, <br /> estimated concentration. Component concentrations showing not detected(ND)are summed into the calculated total result as zero <br /> concentrations. <br /> 7440 Lincoln Way,Garden Grove,CA 92841-1427 • TEL:(714)895-5494 • FAX:(714)894-7501 <br />
