Review of associated batch QC indicates the <br />recovery for this analyte does not represent an out -of -control condition for the batch. <br />QM -07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable LCS <br />recovery. <br />QM -4X The spike recovery was outside of QC acceptance limits for the MS and/or MSD due to analyte concentration at 4 rimes or greater <br />the spike concentration. The QC batch was accepted based on LCS and/or LCSD recoveries within the acceptance limits. <br />QR -03 The RPD value for the sample duplicate or MS/MSD was outside of QC acceptance limits due to matrix interference. QC batch <br />accepted based on LCS and/or LCSD recovery and/or RPD values. <br />DET Analyte DETECTED <br />ND Analyte NOT DETECTED at or above the reporting limit <br />NR Not Reported <br />dry Sample results reported on a dry weight basis <br />RPD Relative Percent Difference <br />Sequoia Analytical - Petaluma The results in this report apply to the samples analyzed in accordance with the chain of <br />custody document.
