Surrogate compound recovery was out of control due to a required sample dilution, therefore, the sample data was reported without further clarification. 2 Surrogate compound recovery was out of control due to matrix interference. The associated method blank surrogate spike compound was in control and, therefore, the sample data was reported without further clarification. 3 Recovery of the Matrix Spike or Matrix Spike Duplicate compound was out of control due to matrix interference. The associated LCS and /or LCSD was in control and, therefore, the sample data was reported without further clarification. 4 The MS /MSD RPD was out of control due to matrix interference. The LCS /LCSD RPD was in control and, therefore, the sample data was reported without further clarification. 5 The PDS /PDSD associated with this batch of samples was out of control due to a matrix interference effect. The associated batch LCS /LCSD was in control and, hence, the associated sample data was reported with no further corrective action required. A Result is the average of all dilutions, as defined by the method. B Analyte was present in the associated method blank. C Analyte presence was not confirmed on primary column. E Concentration exceeds the calibration range. H Sample received and /or analyzed past the recommended holding time. J Analyte was detected at a concentration below the reporting limit and above the laboratory method detection limit. Reported value is estimated. N Nontarget Analyte. ND Parameter not detected at the indicated reporting limit. Q Spike recovery and RPD control limits do not apply resulting from the parameter concentration in the sample exceeding the spike concentration by a factor of four or greater. U Undetected at the laboratory method detection limit. X % Recovery and /or RPD out -of- range. Z Analyte presence was not confirmed by second column or GC /MS analysis. 7440 Lincoln Way, Garden Grove, CA 92841 -1427 • TEL:(714) 895 -5494 • FAX: (714) 894 -7501 CALStAhNUE ENVIRONMENTAL Shell Oil Products US Chain Of Custody Record y LABORATORIES.
