Subject: April 2023 Semi -Annual Sampling Report
Cabarrus County C&D Landfill
Facility Permit No. 1302-CDLF-2006
Dear Ms. Drummond:
CDM Smith Inc., on behalf of Cabarrus County, is submitting an electronic copy of the April 2023 semi-
annual sampling event report for the Cabarrus County C&D Landfill. This letter report presents the
results of the recently completed sampling at the C&D Landfill and constitutes the first semi-annual
sampling event for 2023.
The approved monitoring well network for the C&D Landfill consists of background wells CD-1s and -1d;
compliance wells CD-2, -4 Rep, -7, and -9; and surface water sample location SW-3. CD-4 Rep was
installed in January 2009 as part of the proposed Phase 1 C&D Landfill expansion. Monitoring well CD-7,
formerly piezometer B-7, was added to the monitoring program in July 2014 as part of the Phase 2 C&D
Landfill expansion. Monitoring well CD-9 was installed on March 19, 2017, as part of the Phase 3 C&D
Landfill expansion. Field activities and sampling results for the groundwater and surface water samples
are discussed below.
Field Activities
Groundwater samples from the Cabarrus County C&D Landfill were collected on April 18-21, 2023.
Surface water sample location SW-3 was dry during the April 2023 sampling event. Groundwater
samples were collected from the monitoring wells by use of disposable, laboratory decontaminated
bailers. Monitoring well locations and the surface water location for the C&D Landfill are provided on
Figure 1.
Groundwater elevations were measured at each well on April 17, 2023, prior to sampling and are
presented in Table 1. Well construction details for each monitoring well are also provided in Table 1.
These groundwater elevations were used to construct potentiometric contours for this sampling event

and are presented on Figure 1. After depth to groundwater was measured, each well was purged prior
to sampling to provide fresh formation water within the well water column. Each purge volume was
measured for pH, conductivity, turbidity, temperature, dissolved oxygen, and oxidation-reduction
potential using a YSI-556 multi -parameter water quality meter and a HANNA HI 98703 turbidity meter.
The water quality parameters at the time of sampling are presented in Table 2.
Sampling Results
Pace Analytical Services, LLC, located in West Columbia, South Carolina, analyzed the groundwater
samples for North Carolina Appendix I volatile organic compounds (VOCs) plus tetrahydrofuran, North
Carolina Appendix I metals plus iron, mercury, and manganese, alkalinity, total dissolved solids (TDS),
chloride, and sulfate except for CD-4 Rep. Samples collected from CD-4 Rep were analyzed for North
Carolina Appendix I VOCs and metals.
In a letter dated May 28, 2019, the Solid Waste Section (SWS) requested that all groundwater and
surface water samples collected from landfills be analyzed for 1,4-dioxane after July 1, 2018. On July 1,
2019, the SWS approved the removal of 1,4-dioxane from the sampling program due to two consecutive
non -detect events (January and May 2019), except for SW-3.
The analytical results were reported to the laboratory specific method detection limit (MDL) and are
quantifiable at or below the limit of quantitation (LOQ). All monitoring wells for the C&D Landfill had
detections of analytes above the MDL but below the LOQ. These detections were qualified as estimated
or "J" flags.
In samples collected from CD-7, the detection of manganese had a "D" flag, indicating that the analyte
was analyzed at a dilution greater than one. CD-7 also had a detection of tetrahydrofuran with an "L"
flag, indicating a laboratory control sample/laboratory control sample duplicate failure.
The following list indicates the analytes detected above the LOQ at each sampling location. No "J" flag
detections are provided. Underlined analytes exceeded the 15A NCAC 02L .0202 (NC 2L) Groundwater
Standard or Interim Maximum Allowable Concentration Standard.

"J" flags were not included in the previous list, but samples collected from CD-2 had "J" flag detections
of cobalt, 1,2-dichloroethane, and vinyl chloride that exceeded the standards.
Equipment and trip blanks were analyzed for quality control. A duplicate sample was also analyzed for
quality control. There were no detections in the trip blanks above the MDLs. The equipment blank had
estimated detections of 2-butanone and manganese below their respective NC 2L Groundwater
Standards. The detection of 2-butanone also had an "L" flag. The duplicate sample, identified as DUP,
was collected from CD-7. The duplicate sample had similar concentrations as those detected in CD-7
except for an estimated detection of 1,2-dichloroethane above its NC 2L Groundwater Standard and an

estimated detection of trichlorofluoromethane below its NC 2L Groundwater Standard in the duplicate
sample that were not detected in the parent sample.
Metals detected above the standards are likely naturally occurring based on concentrations in the
background monitoring wells or are from elevated turbidity at the time of sample collection. In
September 2016, CDM Smith submitted an Alternate Source Demonstration (ASD) to the SWS for the
C&D Landfill. As discussed in the ASD, existing contamination in the area is related to a release from the
adjacent Closed Unit 2&3 Landfill and is not from the C&D Landfill. The ASD was approved in October
2016. Contaminants of concern identified in the ASD for the Site included benzene, 1,4-dichlorobenzene,
1,1-dichloroethane, 1,2-dichloroethane, 1,2-dichloropropane, cis-1,2-dichloroethene, methylene
chloride, tetrachloroethene, trichloroethene, and vinyl chloride.
1,1-Dichloroethane, 1,2-dichloroethane, and vinyl chloride were detected above their respective NC 2L
Groundwater Standards in samples collected from CD-2 during the April 2023 sampling event. 1,1-
Dichloroethane was also detected above the standard in CD-2 during the September 2020 sampling
event and from November 2021 through October 2022. Vinyl chloride was previously detected above
the standard in CD-2 during the November 2021 and October 2022 sampling events. This is the first
detection of 1,2-dichloroethane above the standard in CD-2. Benzene has also been detected above the
standard in samples collected from CD-2 during the November 2021 and April and October 2022
sampling events but was detected slightly below the standard in April 2023.
Benzene and vinyl chloride were detected above the NC 2L Groundwater Standards in samples collected
from CD-7 during the April 2023 sampling event. Benzene and vinyl chloride were previously detected
above the standards in samples collected from CD-7 in the November 2021 and April and October 2022
sampling events. In September 2020 and March 2021, only vinyl chloride was detected above the NC 2L
Groundwater Standard in samples collected from CD-7. Future detections above the standards will be
monitored to evaluate trends.
A complete summary of all detected constituents from the April 2023 sampling event is presented in
Table 3. The laboratory analytical report is provided in Appendix A. The next semi-annual sampling
event will be completed in the fall of 2023.

Insufficient sample volume was provided to perform matrix spike/matrix spike duplicate (MS/MSD) for
analytical batch 73639. An LCS/LCSD was run in lieu of an MS/MSD.
The laboratory control sample (LCS) and / or laboratory control sample duplicate (LCSD) for analytical
batch 73639 exceeded acceptance criteria for the following analytes: Chloromethane (143%,141%%),
Vinyl Chloride (131 %). These analytes were biased high and were not detected in the associated
samples: YD20011-001, YD20011-002, and YD20011-004.
YD20011-001 (CD-1d) (Run 1) (Analysis Batch 73639)
