RE: Laboratory Results for
Project Number: 5711 BIRCH DR., Project Name/Desc: Wastewater
ENCO Workorder(s): CF09159
Dear Waylon McFarland,
Enclosed is a copy of your laboratory report for test samples received by our laboratory on
Thursday, June 16, 2022.
Unless otherwise noted in an attached project narrative, all samples were received in
acceptable condition and processed in accordance with the referenced methods/procedures.
Results for these procedures apply only to the samples as submitted.
The analytical results contained in this report are in compliance with NELAC standards, except
as noted in the project narrative if applicable. This report shall not be reproduced except in
full, without the written approval of the Laboratory.
This report contains only those analyses performed by Environmental Conservation
Laboratories. Unless otherwise noted, all analyses were performed at ENCO Cary. Data from
outside organizations will be reported under separate cover.
If you have any questions or require further information, please do not hesitate to contact me.
Sincerely,
Shahla Vakili
Project Manager

FLAGS/NOTES AND DEFINITIONS
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.
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.
QB-05 The calibration blank had a positive result greater than one-half the method reporting limit, the samples in
this sequence were reanalyzed.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based
on acceptable LCS recovery.
R-06 The associated method reporting limit standard exhibited high bias; since the sample result is ND, the
impact on data quality is minimal.
Cf AL This report relates only to the sample as received by the laboratory, and may only be reproduced in full.
