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.

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.

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.

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.
