FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank,
D The sample was analyzed at dilution.
3 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.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentration indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL 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.
PQL PQL: Practical Quantitation Limit. The PQL presented is the laboratory MRL.
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.
[CALC] Calculated analyte - MDL/MRL reported to the highest reporting limit of the component analyses.
3-01 Result may be biased high due to positive results in the associated method blank at a concentration above
the MDL and/or greater than one-half the MRL.
3-04 Result may be biased high. Associated calibration verification standard exceeded the upper control limit.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based
on acceptable LCS recovery.
QS-03 Surrogate recovery outside acceptance limits
QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is ND, there
is no impact.
FINAL This report relates only to the sample as receNed by the laboratory, and may onty be reproduced in fun. I Page 26 0f' 2$
