Dear Mr. Lane:
CDM Smith Inc. (CDM Smith), on behalf of Onslow County (County), is submitting an electronic copy of
the April 2024 semi-annual sampling event report. This letter report presents the results of the recently
completed sampling event at the Onslow County Subtitle D Landfill (Site) and constitutes the first semi-
annual sampling event for 2024. The approved groundwater monitoring network consists of the
following wells: MW-1, -1a, -2, -2a, -4, -5, -6, -7, -8, -8a, -9, -10, -11, and -11a. MW-1 and -1a are the
background monitoring wells for the Site. Monitoring wells MW-10, -11, and -11a were installed on
January 30-31, 2024, as part of the Phase 5 expansion. The Well Installation and Initial Sampling report
was submitted to the Solid Waste Section (SWS) on March 29, 2024. Field activities and sampling and
landfill gas monitoring results from the April 2024 semi-annual sampling event are discussed below.
Field Activities
Groundwater samples from the Site were collected from all wells, except for MW-8a, on April 17-18,
2024, using disposable, laboratory decontaminated bailers. Monitoring well MW-8a was inaccessible
during the April 2024 sampling event. Monitoring well locations are presented 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 and are presented in Table 3. After the 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. 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 North Carolina Appendix I volatile organic compounds (VOCs) and Appendix I metals. Groundwater

samples were also analyzed for per- and polyfluorinated substances (PFAS) in accordance with the SWS
letter dated March 13, 2023. The PFAS laboratory data report is provided in Appendix A.
In a letter dated May 29, 2018, SWS stated that all groundwater 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 at the Site because of two consecutive non-
detect events (December 2018 and May 2019).
The analytical results were reported to the laboratory specific method detection limit (MDLs) and are
quantifiable at or below the method reporting limits (MRLs). The following list indicates analytes
detected above the MRL at each sampling location. Underlined analytes exceeded the 15A NCAC 02L
.0202 (NC 2L) Groundwater Standard. A complete summary of all detected and estimated
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-4. The duplicate sample had similar
concentrations as the primary samples collected from MW-4.
Table 6 presents a summary of all parameters detected during the April 2024 sampling event that
exceeded the NC 2L Groundwater Standards. A summary of the NC 2L Groundwater Standard
exceedances for the Site and the Onslow County Closed Landfill is provided on Figure 2.
CDM Smith, on behalf of the County, submitted the results of an Alternate Source Demonstration (ASD)
for the Site to the SWS on November 8, 2016. The ASD was prepared in accordance with Solid Waste
rule .1633(c)(3), to demonstrate that select metals exceeding the NC 2L Groundwater Standards
detected in monitoring wells at the Site are naturally occurring and not related to a release from the
landfill. As part of the ASD, to determine if turbidity was a contributing factor to total reported metals,
filtered samples were collected during the August 2016 sampling event and analyzed for dissolved
metals. Based on the sampling results, standard metal exceedances were determined to be indicative of
naturally occurring background concentrations as opposed to a release from the landfill.
On November 17, 2017, the SWS requested additional information for an ASD Addendum to address
elevated turbidity (i.e., greater than 10 Nephelometric Turbidity Units (NTUs)) and to determine revised
background levels. As part of the ASD Addendum, background monitoring wells MW-1 and -1a were
redeveloped and sampled during each semi-annual sampling event from August 2016 to September

2020 for a total of nine events to generate non-turbid (i.e., less than 10 NTUs) sample data for
determining revised background and upper tolerance limits (UTLs). The ASD Addendum was submitted
to the SWS on February 19, 2021, proposing UTLs for thallium (0.61 parts per billion (ppb)) and
vanadium (11.4 ppb). On March 10, 2021, the SWS requested six additional sampling events with non-
turbid background sample data to recalculate the UTLs. One data set with turbidity less than 10 NTUs
remains before UTLs can be recalculated.
Filtered samples were collected from MW-7, -9, -11, and -11a during the April 2024 sampling event due
to elevated turbidity. The samples were collected to demonstrate that select metals exceeding the NC
2L Groundwater Standards are naturally occurring and not related to a release from the landfill. Total
metals that exceeded the NC 2L Groundwater Standards or UTLs from these wells were analyzed for
dissolved metals to determine if turbidity was a contributing factor to total reported metals. No
dissolved metals were detected above the MDLs. Based on qualitative and quantitative evaluation of
current and historic groundwater sampling data, the metal exceedances from the April 2024 sampling
event were determined to be indicative of naturally occurring background concentrations as opposed to
a release from the landfill. Dissolved metal sample results are provided in Table 4 and the laboratory
data report is provided in Appendix A.
Onslow County will continue with the detection monitoring program. The next sampling event will be
completed in the fall of 2024.
Landfill Gas Monitoring
The approved landfill gas monitoring network consists of the following wells: M-1, -4, -5, -6, -7, -8, -9,
and -10. M-9 and -10 were installed on January 30-31, 2024, as part of the Phase 5 expansion. 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 Site were completed on January 18 using a
GEM 5000 Plus landfill gas analyzer (GEM) and on May 22, 2024, using an MRU Optima (MRU). No
methane was detected in any monitoring wells or structures during either event. Hydrogen sulfide was
detected in M-9 during the May 2024 monitoring event at 1 part per million. Copies of the quarterly
landfill gas monitoring results, as well as the GEM and MRU calibration data, have been placed in the
landfill operating record and are provided in Appendix B.

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.

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.
