AY = Matrix interference suspected. <br /> BB Sample > 4x spike concentration. <br /> BF Reporting limits raised due to high hydrocarbon background. <br /> BH Reporting limits raised due to high level of non-target analytes. <br /> BU Sample analyzed after holding time expired. <br /> BV Sample received after holding time expired. <br /> BY Sample received at improper temperature. <br /> BZ Sample preserved improperly. <br /> CL Initial analysis within holding time but required dilution. <br /> CQ Analyte concentration greater than 10 times the blank concentration. <br /> CU Surrogate concentration diluted to not detectable during analysis. <br /> DF Reporting limits elevated due to matrix interferences. <br /> DU Insufficient sample quantity for matrix spike/dup matrix spike. <br /> ET Sample was extracted past end of recommended max. holding time. <br /> EY Result exceeds normal dynamic range; reported as a min est. <br /> GR Internal standard recovery is outside method recovery limit. <br /> IB CCV recovery abovelimit; analyte not detected. <br /> IH Calibrtn. verif. recov. below method CL for this analyte. <br /> IJ Calibrtn. verif. recov. above method CL for this analyte. <br /> J,DX J=EPA Flag -Estimated value; DX= Value < lowest standard (MQL), but > than MDL. <br /> LA Confirmatory analysis was past holding time. <br /> LG,AY LG= Surrogate recovery below the acceptance limit. AY= Matrix interference suspected. <br /> LH,AY LH= Surrogate recovery above the acceptance limit. AY= Matrix interference suspected. <br /> LM,AY LM= MS and/or MSD above acceptance limits. See Blank Spike (LCS). AY= Matrix <br /> interference suspected. <br /> LN,AY LN= MS and/or MSD below acceptance limits. See Blank Spike (LCS). AY= Matrix <br /> interference suspected. <br /> LQ LCS recovery above method control limits. <br /> LR LCS recovery below method control limits. <br /> LW Quantitation of unknown hydrocarbon(s) in sample based on gasoline. <br /> LX Quantitation of unknown hydrocarbon(s) in sample based on diesel. <br /> MB Analyte present in the method blank. <br /> ME LCS Recovery Percentage is within LCS ME Control Limit range. <br /> PC Sample taken from VOA vial with air bubble > 6mm diameter. <br /> PI Primary and confirm results varied by > than 40% RPD. <br /> RB RPD exceeded method control limit; % recoveries within limits. <br /> SG A silica gel cleanup procedure was performed. <br /> Solid - Unless otherwise indicated, solid sample data is reported on a wet weight basis, not <br /> corrected for% moisture. <br /> 7440 Lincoln Way, Garden Grove, CA 92841-1427 9 TEL:(714) 895-5494 FAX: (714) 894-7501 <br />
