The <br /> associated method blank surrogate spike compound was in control and, therefore, the <br /> sample data was reported without further clarification. <br /> 3 Recovery of the Matrix Spike (MS)or Matrix Spike Duplicate(MSD) compound was out <br /> of control due to matrix interference. The associated LCS and/or LCSD was in control <br /> and, therefore, the sample data was reported without further clarification. <br /> 4 The MS/MSD RPD was out of control due to matrix interference. The LCS/LCSD RPD <br /> was in control and, therefore, the sample data was reported without further clarification. <br /> 5 The PDS/PDSD or PES/PESD associated with this batch of samples was out of control <br /> due to a matrix interference effect. The associated batch LCS/LCSD was in control and, <br /> hence, the associated sample data was reported without further clarification. <br /> B Analyte was present in the associated method blank. <br /> BU Sample analyzed after holding time expired. <br /> E Concentration exceeds the calibration range. <br /> ET Sample was extracted past end of recommended max. holding time. <br /> J Analyte was detected at a concentration below the reporting limit and above the <br /> laboratory method detection limit. Reported value is estimated. <br /> ME LCS Recovery Percentage is within LCS ME Control Limit range. <br /> ND Parameter not detected at the indicated reporting limit. <br /> Q Spike recovery and RPD control limits do not apply resulting from the parameter <br /> concentration in the sample exceeding the spike concentration by a factor of four or <br /> greater. <br /> X % Recovery and/or RPD out-of-range. <br /> Z Analyte presence was not confirmed by second column or GC/MS analysis. <br /> Solid- Unless otherwise indicated, solid sample data is reported on a wet weight basis, not <br /> corrected for% moisture. All QC results are reported on a wet weight basis. <br /> 7440 Lincoln Way, Garden Grove, CA 92841-1427 • TEL:(714) 895-5494 • FAX: (714)894-7501 <br />
