The analyte was detected in the associated method blank. The reported value is between the laboratory method detection limit (MDL) and the laboratory method reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable. The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation data and moisture content, where applicable. The concentration indicated for this analyte is an estimated value above the calibration range of the instrument. This value is considered an estimate. Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQL) and is based on the low point of the calibration curve, when applicable, sample preparation factor, dilution factor, and, in the case of soil samples, moisture content. MRL E U J D B N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater confidence) to make a tentative identification". P Greater than 25% concentration difference was observed between the primary and secondary GC column. The lower concentration is reported. PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.PQL The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based on acceptable LCS recovery. QM-07 Post-digestion spike did not meet method requirements due to confirmed matrix effects (dilution test). QM-08 Precision between duplicate samples was outside acceptance limits.QM-12 Page 27 of 28This report relates only to the sample as received by the laboratory, and may only be reproduced in full.FINAL
