B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
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.
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.

This compound is a common laboratory contaminant.
The method blank had a positive result for the analyte; however, the concentration In the
method blank is less than 10% of the sample result, which minimizes the impact of the
deviation.
The spike recovery was outside acceptance limits for the MS and/or MSD due to matrix
Interference. The LCS and/or LCSD were within acceptance limits showing that the laboratory Is
in control and the data is acceptable.
The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was
accepted based on acceptable LCS recovery.
Post -digestion spike did not meet method requirements due to confirmed matrix effects
(dilution test).
Precision between duplicate matrix spikes of the same sample was outside acceptance limits.
The RPD result exceeded the QC control limits; however, both percent recoveries were
acceptable. Sample results for the QC batch were accepted based on percent recoveries and
completeness.of QC data.
The associated continuing calibration verification standard exhibited high bias; since the result Is
ND, the impact on data quality Is minimal.

The Qualifiers in this report are defined as follows:
* A quality control analyte recovery is outside of specified acceptance criteria
* * Analyte is a surrogate compound
U Analyte was analyzed for, but not detected above the MDL, MDA, or LOD.
Where the analytical method has been performed under NELAP certification, the analysis has met all of the
requirements of the NELAC standard unless qualified on the Certificate of Analysis.
The designation ND, if present, appears in the result column when the analyte concentration is not detected above
the detection limit.
