Subject: April 2023 Semi -Annual Sampling Report
Cabarrus County Unit 1 Landfill
Facility Permit No. 1302-MSWLF-1974
Dear Ms. Drummond:
CDM Smith Inc., on behalf of Cabarrus County, is submitting an electronic copy of the April 2023 semi-
annual sampling report for the recent event completed at the Cabarrus County Unit 1 Landfill (Unit 1
Landfill). This letter report constitutes the first semi-annual sampling event for 2023. The approved
monitoring well network consists of compliance wells MW-5, -7, -8A, -10, -11, and background wells
CD-1s and -1d. The monitoring network also includes surface water sample locations SW-1 and -2. Field
activities and sampling results for the groundwater and surface water samples are discussed below.
Field Activities
Groundwater and surface water samples from the Unit 1 Landfill were collected on April 19-21, 2023.
Groundwater samples were collected from the monitoring wells by use of a peristaltic pump or
disposable, laboratory decontaminated bailers. Monitoring well and surface water sample locations for
the Unit 1 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-SS6 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) 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 for CD-1s and -1d due to two
consecutive non -detect events (January and May 2019). Samples were collected from MW-5, -7, -8A,
-10, and -11 during the April 2023 sampling event and analyzed for 1,4-dioxane due to previous
detections of 1,4-dioxane. Sample results are provided below.
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 Unit 1 Landfill had
detections of analytes above the MDL but below the LOQ. These detections were qualified as estimated
or "J" flags. Samples collected from MW-5 also had a detection of acetone with an "L" flag, indicating a
laboratory control sample/laboratory control sample duplicate failure.
The following list indicates the VOCs and metals 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 (IMAC). A complete summary of
all detected and estimated concentrations from the May 2012 through the April 2023 sampling events is
presented in Table 3. The laboratory data report is provided in Appendix A.

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 blank above the MDLs. The equipment blank had an
estimated detection of 2-butanone with an 'T' flag below its NC 2L Groundwater Standard. The
duplicate sample, identified as DUP, was collected from MW-10, and had similar analyte concentrations
as those detected in MW-10.
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. VOCs
detected above the standards in several of the compliance wells will continue to be monitored. Table 4
presents a summary of all analytes detected during the April 2023 sampling event that exceeded the NC
2L Groundwater Standards or IMACs. 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.

This Report of Analysis contains the analytical result(s) for the sample(s) listed on the Sample Summary
following this Case Narrative. The sample receiving date is documented in the header information
associated with each sample.
All results listed in this report relate only to the samples that are contained within this report. Where
sampling is conducted by the client, results relate to the accuracy of the information provided, and as the
samples are received.
Sample receipt, sample analysis, and data review have been performed in accordance with the most
current approved The NELAC Institute (TNI) standards, the Pace Analytical Services, LLC ("Pace")
Laboratory Quality Manual, standard operating procedures (SOPS), and Pace policies. Any exceptions to
the TNI standards, the Laboratory Quality Manual, SOPS or policies are qualified on the results page or
discussed below.
Pace is a TNI accredited laboratory; however, the following analyses are currently not listed on our TNI
scope of accreditation: Drinking Water: VOC (excluding BTEX, MTBE, Naphthalene, & 1,2-
dichloroethane) EPA 524.2, E. coli and Total coliforms SM 9223 B-2004, Solid Chemical Material: TOC

VOA 8260D
The continuing calibration verification (CCV) associated with analytical batch 73688 recovered outside
acceptance criteria, low biased, for Dichlorodifluoromethane (-24%). An LOQ standard was analyzed,
and the target analyte was detected. Since the associated samples were non -detect, no corrective action
was taken.
The laboratory control sample (LCS) for analytical batch 73688 exceeded acceptance criteria for the
following analytes: Acetone (195%) and 2-Butanone (149%). These analytes were biased high and were
not detected in the associated sample: YD21009-005.
YD21009-005 (EQ Blank) (Run 1) (Analysis Batch 73688)
The laboratory control sample (LCS) for analytical batch 73820 exceeded acceptance criteria for the
following analytes: Acetone, 2-Butanone, Acrylonitrile, 2-Hexanone and Methacrylonitrile. These analytes
were biased high and were not detected in the associated samples: YD21009-001, YD21009-002,
YD21009-003, and YD21009-004.

The laboratory control sample (LCS) for analytical batch 73820 exceeded acceptance criteria for the following
analytes: Acetone, 2-Butanone, Acrylonitrile, 2-Hexanone and Methacrylonitrile. These analytes were biased
high and were not detected in the associated samples: YD22002-001, YD22002-002, and YD22002-003.
YD22002-001 (MW-5) (Run 1) (Analysis Batch 73820)
