FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
J 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.
1-04 Result may be biased high. Associated calibration verification standard exceeded the upper
control limit.
3-06 The associated laboratory control sample exhibited low bias; the reported result should be
considered to be a minimum estimate.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was
accepted based on acceptable LCS recovery.
QV-01 The associated continuing calibration verification standard exhibited high bias; since the result is
ND, there is no impact.
QV-02 The associated continuing calibration verification standard exhibited low bias; the reported
result should be considered to be a minimum estimate.
