Therefore, the sample <br /> data was reported without further clarification. <br /> 2 Surrogate compound recovery was out of control due to matrix interference. The associated method blank <br /> surrogate spike compound was in control and, therefore, the sample data was reported without further <br /> clarification. <br /> 3 Recovery of the Matrix Spike(MS)or Matrix Spike Duplicate(MSD)compound was out of control due to <br /> matrix interference. The associated LCS and/or LCSD was in control and, therefore, the sample data was <br /> reported without further clarification. <br /> 4 The MS/MSD RPD was out of control due to matrix interference. The LCS/LCSD RPD was in control and, <br /> 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 due to a matrix <br /> interference effect. The associated batch LCS/LCSD was in control and, hence, the associated sample <br /> data was reported without further clarification. <br /> 6 Surrogate recovery below the acceptance limit. <br /> 7 Surrogate recovery above the acceptance limit. <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 /> HD The chromatographic pattern was inconsistent with the profile of the reference fuel standard. <br /> HDH The sample chromatographic pattern for TPH matches the chromatographic pattern of the specified <br /> standard but heavier hydrocarbons were also present(or detected). <br /> HDL The sample chromatographic pattern for TPH matches the chromatographic pattern of the specified <br /> standard but lighter hydrocarbons were also present(or detected). 0 <br /> J Analyte was detected at a concentration below the reporting limit and above the laboratory method <br /> detection limit. Reported value is estimated. <br /> ME LCS/LCSD Recovery Percentage is within Marginal Exceedance(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 concentration in the <br /> sample exceeding the spike concentration by a factor of four or greater. <br /> SG The sample extract was subjected to Silica Gel treatment prior to analysis. <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 corrected for <br /> % moisture. All QC results are reported on a wet weight basis. <br /> MPN - Most Probable Number <br /> 7440 Lincoln Way, Garden Grove, CA 92841-1427 • TEL:(714) 895-5494 FAX: (714)894-7501 <br />
