Onslow County Closed Landfill
Facility Permit # 6705-MSWLF-1984
Dear Mr. Lane:
CDM Smith Inc., on behalf of Onslow County, is submitting an electronic copy of the 2024 semi-annual
sampling event report. This letter report presents the results of the recently completed sampling event
at the Onslow County Closed Landfill and constitutes the first semi-annual sampling event for 2024. The
approved groundwater monitoring network consists of monitoring wells MW-1S, -1D, -5, -6, -7, -8, and
-9, and surface water sample locations SW-1, -2, and -3. MW-1S and -1D are the background monitoring
wells for the Closed Landfill. Field activities, sampling, and landfill gas monitoring results are discussed
below.
Field Activities
Groundwater samples from the Onslow County Closed Landfill were collected on April 17-18, 2024. All
surface water locations were dry during the April 2024 sampling event. Groundwater samples from each
well were collected by use of disposable, laboratory decontaminated, bailers. Monitoring well locations
are shown on Figure 1 and well construction details are provided in Table 1.
Groundwater elevations were measured at each well on April 17, 2024, prior to sampling and are
presented in Table 2. These groundwater elevations were used to construct potentiometric contours for
this sampling event as shown on Figure 1. The groundwater elevations and potentiometric contours
were used to estimate groundwater velocities at each well as provided in Table 3. After depth to
groundwater was determined, three well volumes of water were removed from each well prior to
sampling to provide fresh formation water within the well water column. Each well volume was
measured in the field for pH, conductivity, temperature, turbidity, dissolved oxygen, and oxidation-
reduction potential using a YSI-556 multi-parameter water quality meter and a HACH 2100Q turbidity
meter. Monitoring wells MW-5, -8, and -9 had elevated turbidities at the time of sampling (i.e., greater
than 10 Nephelometric Turbidity Units). Water quality parameters at the time of sampling are presented
in Table 4.
Sampling Results
Pace Analytical Services, LLC, located in Huntersville, North Carolina, analyzed the groundwater samples
for the North Carolina Appendix I volatile organics and Appendix I metals. Groundwater samples were
also analyzed for per- and polyfluorinated substances (PFAS) in accordance with the Solid Waste
Section’s (SWS) letter dated March 13, 2023. In a letter dated May 29, 2018, the SWS stated that all

Mr. Ervin Lane

groundwater and surface water samples collected from landfills be analyzed for 1,4-dioxane after July 1,
2018. On July 18, 2019, the SWS approved the removal of 1,4-dioxane from the sampling program for all
monitoring wells and surface water locations, with the exceptions of MW-7 and SW-2, due to two
consecutive non-detect events (December 2018 and May 2019). Samples were collected from MW-7
during the April 2024 semi-annual sampling event and analyzed for 1,4-dioxane. Sample results are
provided below. The PFAS laboratory data report is provided in Appendix A.
Analytical results were reported to the laboratory method detection limits (MDLs) and are quantifiable
at or below the method reporting limits (MRLs). The following list indicates analytes detected above the
MRLs at each sampling location. Underlined analytes exceeded the 15A NCAC 02L .0202 (NC 2L)
Groundwater Standard. A complete summary of detected concentrations from May 2012 to April 2024 is
presented in Table 5. The laboratory data report is provided in Appendix A.

Equipment and trip blanks were analyzed for quality control. A duplicate sample was also collected for
quality control. There were no detections in the trip blank or equipment blank above the MDLs. The
duplicate sample, labeled DUP, was collected from MW-5, and had similar concentrations as the primary
sample. A summary of all NC 2L Groundwater Standard exceedances is presented in Table 6 and are
provided on Figure 2.
Onslow County will continue with the detection monitoring program. The concentration of 1,4-dioxane
will continue to be monitored at MW-7. The next sampling event will be completed in the fall of 2024.
Landfill Gas Monitoring Results
The approved landfill gas monitoring network consists of the following wells: M-1, -2A, -3A, -4, -5, -6, -7,
-8, -9, -10, -11, -12, -13, -14, -15R, and -16. Site structures that are monitored on the property include
the scale house, administration building, materials recycling facility, storage building, maintenance shop,
vehicle maintenance facility, and leachate storage tanks. Landfill gas monitoring events for the Closed
Landfill were completed on January 18 and May 22, 2024, using a GEM 5000 Plus landfill gas analyzer
(GEM) and an MRU Optima (MRU), respectively. Methane was detected below the 5 percent lower
explosive limit in M-15R during the January 2024 monitoring event and in M-2 during the May
monitoring event, at 0.4 and 0.91 percent by volume, respectively. Hydrogen sulfide was detected in
M-15R during both 2024 monitoring events at 21 parts per million (ppm) and 1 ppm, respectively.
Hydrogen sulfide was also detected in M-9 during the May 2024 monitoring event at 1 ppm. Copies of
the quarterly landfill gas monitoring results along with the GEM and MRU calibration information have
been placed in the landfill operating record and are provided in Appendix B.
If you have any questions or require further explanation, do not hesitate to call me at [phone].
Sincerely,

Janelle Farley, P.G.

DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL - Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean-Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TNI - The NELAC Institute.
ANALYTE QUALIFIERS
