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 or Matrix Spike Duplicate compound was out of control due <br />to matrix interference. The associated LCS and/or LCSD was in control and, therefore, <br />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 associated with this batch of samples was out of control due to a matrix <br />interference effect. The associated batch LCS/LCSD was in control and, hence, the <br />associated sample data was reported with no further corrective action required. <br />A Result is the average of all dilutions, as defined by the method. <br />B Analyte was present in the associated method blank. <br />C Analyte presence was not confirmed on primary column. <br />E Concentration exceeds the calibration range. <br />H Sample received and/or analyzed past the recommended 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 />N Nontarget Analyte. <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 />U Undetected at the laboratory method detection limit. <br />X % Recovery and/or RPD out -of -range. <br />Z Analyte presence was not confirmed by second column or GC/MS analysis. <br />7440 Lincoln Way, Garden Grove, CA 92841-1427 • TEL:(714) 895-5494 • FAX: (714) 894-7501 <br />
