Reference: Quarterly Report 6 — Maynard Road Nitrogen Removal Water Quality Study
On behalf of the Town of Cary, this letter is to serve as the sixth quarterly report for the Maynard Road
Nitrogen Removal Water Quality Study. The yearly interim report was submitted in July of 2014.
Water quality samples were collected at the project area on November 26 and December 16, 2014 at the
upstream (Site #lo) and downstream (Site #1) water quality sites. Flow monitoring was also conducted at
the corresponding flow sites (Site #lo and Site #11, respectively). Precipitation levels for the sampling date
were also retrieved.
Laboratory reports for the sampling events are attached.

Dear Kristin Weidner,
Enclosed is a copy of your laboratory report for test samples received by our laboratory on
Wednesday, November 26, 2014.
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. This report shall not be reproduced except in full, without

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.
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.
QM -16 Matrix spike recovery could not be calculated due to high concentrations of analyte in source
sample.

I FLAGS /NOTES AND DEFINITIONS M
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.
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.
