V. ADDITIONAL REGIONAL STAFF REVIEW ITEMS
Due to the need to expand the N. Harnett Regional Wastewater Treatment plant; Harnett County has installed
two 600K holding tanks and constructed an enclosed structure with two centrifuges to dewater wastewater
residuals generated by the N. Harnett WWTP and residuals stored in the on -site lagoon (former facultative
lagoon used by the Town of Lillington, original owner the of wastewater treatment plant). One tank is
dedicated to wastewater residuals and one tank is dedicated to residuals received from the Harnett Water
Treatment Plant. 90 plus days of residuals storage (both wastewater and water treatment) is available within
the structure constructed. See attached photos and site map.
Currently, Harnett County is transporting cake residuals to the Sampson County Disposal landfill (DWM/82-
02 MSWLF) for disposal from the N. Harnett WWTP, S. Harnett Regional WWTP and Harnett WTP. Harnett
County is also exploring the option to take cake residuals to McGill Environmental in southern Sampson
County (DWR permit WQ0006816).
Harnett County has suspended land applying liquid residuals and their contract with Synagro. Harnett County
is reaching out to other land application contractors for bids to manage liquid residuals in the future. Until a
new land application contractor is retained, all residuals generated by Harnett County will be dewatered and
transported to the Sampson County Disposal or McGill Environmental.

] 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.
www.encolabs.com
The analyte was detected in the associated method blank.
The sample was analyzed at dilution.
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.
Q-01 Analysis performed outside of method - specified holding time.
Q-02 Sample received outside of method - specified holding time.
QB-01 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. There is minimal impact to the data,
QB-02 The method blank contains analyte at a concentration above the MDL and/or greater than one-half the
MRL. The analyte was not detected in the sample.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based
on acceptable LCS recovery.
QM-08 Post -digestion spike did not meet method requirements due to confirmed matrix effects (dilution test).
QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits.
FINAL This report relates only to the sample as received by the laboratory, and may only be reproduced in full.

FLAGS/NOTES AND DEFINITIONS

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.
www.encolabs.com
The analyte was detected in the associated method blank.
The sample was analyzed at dilution.
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.
Q-01 Analysis performed outside of method - specified holding time.
QB-02 The method blank contains analyte at a concentration above the MDL and/or greater than one-half the
MRL. The analyte was not detected in the sample.
QM-07 The spike recovery was outside acceptance limits for the MS and/or MSD. The batch was accepted based
on acceptable LCS recovery.
QM-11 Precision between duplicate matrix spikes of the same sample was outside acceptance limits.
FINAL This report relates only to the sample as received by the laboratory, and may only be reproduced in full.
