Executive Summary
On behalf of Waste Management of Carolinas, Inc. (Waste Management) and Randolph County, WSP USA Inc.
(WSP), is pleased to submit the enclosed Water Quality Monitoring Report, which documents the results of the
October 31 to November 6, 2023, groundwater and surface water sampling event at the closed Randolph County
Landfill, North Carolina (NC) Solid Waste Permit (SWP) No. 76-01.
Cobalt was detected at estimated concentrations below the practical quantitation limit (PQL), but above the NC 2L
Standard in the samples collected from downgradient monitoring wells MW-7 and MW-10S. The estimated cobalt
concentrations are generally consistent with historical data. Per 15A NCAC 02L .0202 (b)(1), “where the standard
(i.e., the NC 2L Standard) for a substance is less than the PQL, the detection of that substance at or above the
PQL constitutes a violation of the standard.” Cobalt has been intermittently detected in samples collected from
the upgradient monitoring well, MW-5, at similar or higher concentrations suggesting that cobalt is naturally
occurring or could be from an off-site source. No other inorganic constituents were detected in samples collected
from the groundwater compliance network at concentrations above applicable groundwater quality standards
during this sampling event.
Four NC Appendix I listed organic constituents, 1,1-dichloroethane, tetrachloroethene, benzene, and vinyl
chloride, were detected at quantified concentrations above their respective PQLs and NC 2L Standards in
samples collected from one or more downgradient compliance monitoring wells during the second semi-annual
2023 sampling event, as they have been historically. The constituent 1,4-dioxane was detected at quantified
concentration above the NC 2L Standard in the samples collected from the downgradient monitoring wells MW-6,
MW-7, and MW-10S. 1,4 dioxane is currently sampled in accordance with the May 29, 2018 NC DEQ
memorandum and is not currently required by permit or regulation. Future trends for the detection of 1,4-dioxane
will be monitored. No other organic compounds were detected at concentrations above the applicable
groundwater standards during the second semi-annual 2023 sampling event.
No NC Appendix I constituents were detected at concentrations above their applicable surface water standards in
the samples collected from surface water monitoring points during the second semi-annual 2023 sampling event.
According to the current data and as indicated by the BIOCHLOR model described in detail in this report, it is
likely that the plume size has stabilized. Because of the low concentration of parent compounds and multiple
degradation pathways for cis-1,2-dichloroethene (e.g., aerobic and anaerobic), there are limited concentrations of
vinyl chloride and ethene in each of the plumes evaluated. The concentration trends show that cis-1,2-
dichloroethene is not accumulating and that degradation of the chlorinated compounds is continuing.
Based on the second semi-annual 2023 analytical results, the uppermost aquifer beneath this facility should
continue to be monitored in accordance with the requirements of the Assessment Monitoring Program as outlined
in Title 15A of North Carolina Administrative Code (NCAC) Subchapter 13B Rule .1634. The County will continue
to sample according to the reduced monitored natural attenuation (MNA) parameter list approved by NC
Department of Environmental Quality (DEQ) on October 18, 2017. The next sampling event is tentatively
scheduled for May 2024.

1.0 INTRODUCTION
On behalf of Waste Management of Carolinas, Inc. (Waste Management) and Randolph County, North Carolina
(NC), WSP USA Inc. (WSP), is submitting this Water Quality Monitoring Report in accordance with Title 15A of
the North Carolina Administrative Code (NCAC) Subchapter 13B .1634. This report summarizes the results of the
October 31 to November 6, 2023 sampling event at the closed Randolph County Landfill located in Randolph
County, NC. The Randolph County Landfill is a closed municipal solid waste (MSW) landfill and is maintained by
Waste Management under NC Solid Waste Permit No. 76-01 issued by the NC Department of Environmental
Quality (DEQ).
1.1 Site Description and Background
The location of the closed Randolph County Landfill is shown on the inlay on Figure 1. The facility is located
approximately 3 miles northeast of the city of Asheboro, near the town of Central Falls in Randolph County, NC.
Randolph County operated a sanitary landfill from 1973 to 1985. A second sanitary landfill for MSW, construction
and demolition (C&D) debris, and land clearing and inert debris (LCID) was operated from 1985 to December 31,
1997. The facility is located on approximately 600 acres, approximately half of which contains waste or is
associated with activities for the convenience center and the County’s solid waste transfer station. The existing
transfer station was built before final landfill closure in 1997 and operated until the opening of the Great Oak
Landfill near Cedar Falls in 2017. Because it operated past October 9, 1993, the Randolph County landfill is
subject to Title 15A NCAC 13B .1630 of the NC Solid Waste Management Regulations (SWMR).
As shown on Figure 1, the landfill is accessible by County Land Road to the southwest. The landfill is bound to
the north by the Deep River and bordered to the west, south, and east by residential and undeveloped, wooded
properties. Topographic relief at the landfill ranges from approximately 580 to 725 feet above mean sea level
(amsl). Surface drainage from the facility is toward an unnamed perennial stream to the west and a natural valley
to the east. Runoff from both features drains into the Deep River located northeast of the landfill (H&S, 1994).
1.2 Compliance Monitoring History
Groundwater monitoring wells for the second sanitary landfill have been sampled since 1987. The facility has
been in the assessment monitoring program since 1996, due to detections of volatile organic compounds (VOCs)
in groundwater samples at concentrations above applicable standards. The current Water Quality Monitoring
Plan (WQMP) was included in the facility’s Transition Plan, dated October 8, 1994, and was subsequently
approved by NC DEQ, formerly the NC Department of the Environment and Natural Resources (DENR), in 1995.
In accordance with the WQMP, the current water quality monitoring system consists of six groundwater monitoring
wells (MW-5, MW-6, MW-7, MW-8, MW-9, and MW-10S) and four surface water monitoring points [SW-1 and
SW-3 (upstream) and SW-2 and SW-4 (downstream)].
A Nature and Extent Study (NES) was submitted to the NC DEQ on April 12, 2013, in response to exceedances of
VOCs in groundwater samples collected from the monitoring network. The NES was approved by NC DEQ on
June 8, 2013. An Assessment of Corrective Measures (ACM) was submitted to NC DEQ on October 3, 2013 and
was approved on December 2, 2013. A Corrective Action Plan (CAP) was submitted to NC DEQ on July 31, 2015
and approved on September 10, 2015. As specified in the CAP, monitored natural attenuation (MNA) was
implemented as the corrective action for the facility. As part of the Corrective Action Performance Monitoring Plan
(CAPMP), which was approved as part of the CAP, downgradient monitoring well MW-1 was replaced with
monitoring well MW-10S. Monitoring well MW-1 remains for the collection of water level data only. Per the
CAPMP, monitoring wells MW-2, MW-3, MW-10D, and MW-11S are sampled semi-annually as MNA corrective

action monitoring wells. A Corrective Action Evaluation Report (CAER) was submitted to NC DEQ on May 4,
2021. The CAER requested that 1,4-dichlorobenzene, 1,2-dichloroethane, cis-1,2-dichloroethene, methylene
chloride, and 4 Methyl-2-pentanone be removed as constituents-of-concern (COCs) for the facility. The CAER
was approved by NC DEQ on May 10, 2021. Sampling and analysis of 1,4-dioxane is currently performed in
accordance with a May 2018 Memorandum from NC DEQ. Aside from the May 2018 Memorandum, 1,4-dioxane
is not currently included in the NC Solid Waste Management Rules, nor in the facility’s permit.
1.3 Hydrogeologic Setting
Geologically, the facility is located within the Carolina Slate Belt of the Piedmont Physiographic Province of NC.
The Carolina Slate Belt is composed of Late Proterozoic to Cambrian aged meta-sedimentary and meta-volcanic
rocks that locally have been intruded by diabase dikes and felsic intrusive suites (NCGS, 1985). The facility is
underlain primarily by felsic meta-volcanic tuffs with massive fabrics to steeply dipping foliations (GSA, 2008).
STS Consultants Ltd. conducted a geologic and hydrogeologic investigation as part of the Phase II Landfill
Expansion in late 1984 and 1985 (H&S, 1994). The topography of the area is characterized by rolling rounded
hills and flat valleys with sharp draws containing streams and ponds. The surficial geology on-site consists of
saprolite (i.e., residual soils weathered from bedrock). The saprolite generally consists of clayey silts and silty
clays with some sandy silts and silty sands (H&S, 1994).
The uppermost groundwater beneath the facility is present in a shallow unconfined aquifer comprised of partially
weathered fractured meta-volcanic rock. Due to the rolling topography, groundwater occurs at depths ranging
from approximately 4 to 66 feet below grade. Depth-to-water measurements obtained during the October 2023
monitoring event are summarized in Table 1 and were used to prepare a groundwater surface contour map
presented on Figure 1.
As shown on Figure 1, the groundwater flow in the uppermost aquifer beneath the site is generally to the north or
northeast toward the Deep River which is located along the northern property boundary. The groundwater
contour map and interpreted flow directions are consistent with those previously submitted for this facility.
Based on the October 2023 groundwater surface contour map, the average hydraulic gradient in the shallow
aquifer underlying the site, as measured along the conceptual flow path shown on Figure 1, was calculated to be
approximately 0.065 foot/foot (Table 2). Based on a local hydrogeologic investigation, a hydraulic conductivity of
2.75E-04 centimeter/second was used in linear groundwater velocity calculations (GSA, 2008). An estimated
effective porosity of 0.15 was used for the shallow aquifer to represent a range from saprolite to fractured rock
(H&S, 1997).
Using the above values, the estimated rate of groundwater flow for the uppermost aquifer beneath the facility was
calculated using the following modified Darcy equation: 𝑉𝑉𝑔𝑔𝑔𝑔= 𝐾𝐾 𝑥𝑥 𝑖𝑖𝑛𝑛𝑒𝑒
where Vgw = average linear velocity (feet/year), K = hydraulic conductivity (feet/year), i = horizontal hydraulic
gradient, and ne = effective porosity.
The average estimated linear groundwater flow velocity under the waste management unit is approximately 124
feet/year, which is generally consistent with previous estimates (Table 2). The range of groundwater flow rates is
expected to vary depending on the hydrogeologic unit in which it occurs. However, the linear velocity equation
above makes the simplified assumption of a homogeneous and isotropic aquifer. Therefore, this equation
February 2024 31404568.018

represents a likely average value for the uppermost aquifer and does not account for heterogeneous and/or
anisotropic conditions that may be present in the uppermost aquifer at the facility. The saprolite may have areas
that exhibit relict foliation, and these structures can result in locally anisotropic groundwater flow directions.
2.0 FIELD PROGRAM, MONITORING RESULTS, AND DISCUSSION
Field activities conducted for the second semi-annual 2023 sampling event completed in October and November
2023 are discussed in the following sections.
2.1 Visual Inspection Program
To detect a potential release at the earliest possible time, a visual inspection program is used by sampling crews
at the closed Randolph County Landfill. This program includes observations of physical indicators such as
potential water table mounding beneath the waste management unit, physical examination of any stresses in
biological communities, visible signs of leachate migration (i.e., leachate seeps), unexplained changes in soil
characteristics, and any other changes to the environment due to the waste management unit. During this
compliance monitoring event, no physical indicators of a potential release were observed in the vicinity of the
waste management area.
2.2 Well Network and Groundwater Elevation Measurements
The current groundwater monitoring network at the closed Randolph County Landfill consists of six monitoring
wells (MW-5, MW-6, MW-7, MW-8, MW-9, and MW-10S). Additionally, four monitoring wells (MW-2, MW-3, MW-
10D, and MW-11S) are sampled semi-annually as performance monitoring wells associated with the MNA
corrective action remedy. Available monitoring well construction information is summarized on Table 3, and the
well locations are shown on Figure 1. The groundwater monitoring network was constructed to target the
preferential flow path for groundwater underlying waste management units (i.e., partially weathered fractured rock
that comprises the unconfined uppermost aquifer). Two on-site surface water points (upstream SW-1 and
downstream SW-2) and two off-site surface water points (upstream SW-3 and downstream SW-4) are also
monitored to assess water quality at the site in conjunction with groundwater monitoring network.
Monitoring well MW-5 is the facility’s background well and is located hydraulically upgradient of the waste
management units. Monitoring wells MW-6, MW-7, MW-8, MW-9, and MW-10S are located downgradient of the
waste management units and represent the facility’s downgradient compliance network. Monitoring wells MW-7,
MW-8, MW-9, and MW-10S are screened in the shallow unconfined aquifer while monitoring wells MW-5 and
MW-6 are screened in fractured bedrock. Additionally, water levels are measured during each sampling event at
nine observation wells: MW-1, MW-2, MW-3, MW-4, MW-10D, MW-11S, MW-A1, MW-A2, and MW-A3. These
measurements supplement groundwater elevation data obtained from the compliance monitoring wells and are
used in the creation of the groundwater contour map included as Figure 1.
Depth-to-water measurements were recorded to the nearest 0.01 foot prior to initiating groundwater purging and
sampling activities. A summary of the current and historical water level elevations is presented in Table 1. As
presented, the data indicate that the hydraulic head level in the uppermost aquifer beneath the facility is relatively
consistent with temporal variation, with the long-term average ranging from approximately 2 to 20 feet (plus or
minus). As expected, the range in fluctuation appears to be greatest in upgradient well MW-5 which is located in
a groundwater recharge area. The range of fluctuation in downgradient compliance wells MW-6, MW-7, MW-8,
MW-9, and MW-10S, located near groundwater discharge areas, is less, presumably due to the stabilizing effect
of the hydraulic discharge boundary.

2.3 Second Semi-Annual 2023 Monitoring Event
Personnel from WSP visited the facility on October 31 to November 6, 2023 to purge and sample groundwater
monitoring wells MW-2, MW-3, MW-5, MW-6, MW-7, MW-8, MW-9, MW-10S, MW-10D, and MW-11S, and to
sample surface water monitoring points SW-1, SW-2, SW-3, and SW-4. Monitoring wells were purged with
dedicated bladder pumps using low-flow micropurge procedures in accordance with applicable United States
Environmental Protection Agency (USEPA) and NC DEQ sampling protocols. Field measurements of
temperature, pH, specific conductivity, dissolved oxygen (DO), oxidation-reduction potential (ORP), and turbidity
were recorded periodically (i.e., approximately every 3 to 5 minutes based on the purge rate and flow cell volume)
with field-calibrated instruments during the micro-purge process. In general, the purge rate for each well was
matched to the yield of the monitoring well, as determined by continuously monitoring the depth to the water, up to
a maximum purge rate of 500 milliliters per minute. Each monitoring well was purged until stabilization was
indicated by the water quality parameters. Monitoring well MW-5 (i.e., the background well) was not sampled
during this event due to an inadequate volume of groundwater. SW-1 and SW-2 sampling locations were dry
during this event, no sample was collected.
Prior to sampling, laboratory-supplied sample containers were prepared. Each sample container was labeled with
the sample identification number, sampling personnel, date and time of sample collection, project name and
number, and requested chemical analysis. The groundwater samples were collected directly from the inline tubing
connected to the dedicated bladder pumps. Samples were placed into pre-preserved sample containers after
purging was considered complete based on the stabilization of field parameters.
Surface water samples were collected directly from the stream flow by lowering the sample containers into the
stream with the opening facing away from the current flow, taking care to prevent the overflow of the sample
containers and to minimize sample-induced turbidity. Measurements of temperature, pH, specific conductivity,
DO, ORP, and turbidity were recorded during the collection of the surface water samples.
After collection, the groundwater and surface water samples were placed in a cooler on ice, under chain-of-
custody control. Copies of the sampling logs are presented in Appendix A. Included in each log is a description
of the sampling equipment, sampling location, sampling method, field observations, and field measurements.
2.4 Laboratory Analysis Program
For the second semi-annual 2023 compliance monitoring, groundwater and surface water samples were shipped
via courier on November 3 and 6, 2023 to Eurofins Raleigh (Eurofins) located in Cary, NC under chain-of-custody
control. As noted in the laboratory reports included in Appendix B, samples from monitoring wells MW-6, MW-7,
MW-8, MW-9, and MW-10S and from surface water monitoring points SW-3, and SW-4 were received at the
laboratory on November 3 and 6, 2023 in good condition and properly preserved.
The MNA groundwater samples were shipped to Pace Analytical Gulf Coast (Pace) of Baton Rouge, Louisiana
under chain-of-custody control. Groundwater samples from MW-2, MW-3, MW-7, MW-8, MW-10S, MW-10D, and
MW-11S were shipped on November 1, 2, and 6, 2023. Each sample shipment was received at the lab the
following day in good condition.
2.4.1 Compliance Monitoring
The compliance groundwater samples were analyzed for the NC Appendix II constituent list. Surface water
samples were analyzed for the NC Appendix I constituent list. Compliance groundwater and surface water
February 2024 31404568.018
5
samples collected during this event were also analyzed for 1,4-dioxane per the May 29, 2018, NC DEQ
memorandum.
2.4.2 Corrective Action Monitoring
A reduced list of MNA parameters was approved by the NC DEQ Solid Waste Section (SWS) in a letter dated
October 18, 2017. However, the full MNA parameter list is required during back-to-back events every three years.
The second full MNA event was completed with the second semi-annual 2023 sampling event. Groundwater from
compliance monitoring wells MW-7, MW-8, and MW-10S, and corrective action wells MW-2, MW-3, MW-10D, and
MW-11S, were analyzed for the following MNA parameters: carbon dioxide, chloride, ethane, ethene, methane,
hydrogen, ferrous iron, nitrate, nitrite, volatile fatty acids, sulfate, total organic carbon, biological oxygen demand
(BOD), and chemical oxygen demand (COD). Corrective action wells MW-2, MW-3, MW-10D, and MW-11S were
also analyzed for COCs, which include benzene, 1,1-dichloroethane, tetrachloroethene, trichloroethene, and vinyl
chloride. As presented in Section 2.3, monitoring well MW-5 was not sampled during the second semi-annual
2023 sampling event as there was an inadequate volume of groundwater to collect a sample.
3.0 LABORATORY AND FIELD QA/QC
A laboratory-prepared trip blank accompanied the volatile sample from the Eurofins laboratory for the October
2023 sampling event to and from the laboratory. Eurofins analyzed the trip blank for NC Appendix II VOCs.
Reviews of the laboratory data were performed by WSP personnel and are included in Appendix B. Based on
the data review, no B flags were assigned during this event.
Reviews of the Pace Analytical laboratory reports for MNA parameters showed that the following analyses were
sampled out of the recognized hold time: ferrous iron, nitrate, and BOD. However, based on the current results
compared to the historical data, the data was deemed acceptable to be used in the MNA evaluation.
4.0 DATA EVALUATION
The results of the data evaluations are presented in the following sections.
4.1 North Carolina Groundwater and Surface Water Standard Comparisons
Analytical results and field parameters for the second semi-annual 2023 groundwater samples are summarized in
Table 4 and Table 5 along with available historical data. The laboratory certificates-of-analysis, chain-of-custody
forms, and laboratory data reviews for the sampling event are included in Appendix B.
One inorganic constituent, cobalt, was detected at a quantified concentration below the practical quantitation limit
(PQL) but above the NC 2L Groundwater Standard (NC 2L Standard) in samples collected from the downgradient
monitoring MW-7 and W-10S during this monitoring event. The cobalt concentrations are generally consistent
with historical data. With regards to the estimated cobalt concentrations detected in samples collected from MW-7
and MW-10S, per 15A NCAC 02L .0202 (b)(1), “where the standard (i.e., the NC 2L Standard) for a substance is
less than the PQL, the detection of that substance at or above the PQL constitutes a violation of the standard.”
Cobalt has been intermittently detected in samples collected from the upgradient monitoring well, MW-5, at similar
or higher concentrations suggesting that cobalt is naturally occurring or could be from an off-site source. No other
inorganic constituents were detected in samples collected from the groundwater compliance network at
concentrations above applicable groundwater quality standards during this sampling event.

As presented in Table 4, four NC Appendix I listed organic constituents, 1,1-dichloroethane, tetrachloroethene,
vinyl chloride, and benzene, were detected at quantified concentration above the PQL and NC 2L Standard in
samples collected from various downgradient compliance monitoring wells during the second semi-annual 2023
sampling event, as they have been historically. The constituent 1,4-dioxane was detected at quantified
concentration above the NC 2L Standard in the samples collected from the downgradient monitoring wells MW-6,
MW-7, and MW-10S. 1,4 dioxane is currently sampled in accordance with the May 29, 2018 NC DEQ
memorandum and is not currently required by permit or regulation. Future trends for the detection of 1,4-dioxane
will be monitored. No other organic compounds were detected at concentrations above the applicable
groundwater standards during the second semi-annual 2023 sampling event.
Analytical results and field parameters for the second semi-annual 2023 sampling event surface water samples
are summarized in Table 6 and 7 along with available historical data. No NC Appendix I constituents were
detected at concentrations above their applicable surface water standards in the samples collected from surface
water monitoring points during this event.
4.2 Corrective Action Performance Monitoring Results and Monitored Natural Attenuation Evaluation
The CAPMP was approved as part of the CAP by NC DEQ on September 15, 2015. Per the CAPMP, MNA
background sampling began during the October 2015 semi-annual water quality monitoring event. The MNA
sampling program was updated with the submission of a CAER on May 4, 2021 and approved by NC DEQ on
May 10, 2021. With approval of the CAER, 1,4-dichlorobenzene, 1,2-dichloroethane, cis-1,2-dichloroethene,
methylene chloride, and 4 methyl-2-pentanone were removed as COCs for the facility.
4.3 Corrective Action Performance Monitoring Results
Per the CAPMP, corrective action monitoring wells MW-2, MW-3, MW-10D, and MW-11S were sampled in
addition to the compliance monitoring wells during the second semi-annual 2023 sampling event. Samples
collected from MW-2, MW-3, MW-7, MW-8, MW-10S, MW-10D, and MW-11S were analyzed for select MNA
parameters, which included: carbon dioxide, chloride, ethane, ethene, methane, hydrogen, ferrous iron, nitrate,
nitrite, volatile fatty acids, sulfate, total organic carbon, biological oxygen demand, and chemical oxygen demand.
A sample for MNA parameters could not be obtained from monitoring well MW-5 due to an inadequate volume of
groundwater. A summary of the MNA parameter data is included as Table 8, and the laboratory certificates-of-
analyses are included in Appendix B
4.4 Monitored Natural Attenuation Evaluation
In accordance with the CAPMP, monitoring wells MW-2, MW-3, MW-7, MW-8, MW-10S, MW-10D, and MW-11S
serve as performance evaluation wells to assess the effectiveness of the MNA processes in reducing
concentrations of COCs at the site. These monitoring wells were selected as they are located in the areas
designated for corrective action by MNA in the approved CAP. The second semi-annual 2023 analytical data for
these monitoring wells were evaluated using the US EPA’s ”Natural Attenuation Screening Protocol (1998)” tool.
Based on EPA screening protocols, monitoring wells MW-10S received a score of 24, which indicates adequate to
strong evidence for anaerobic biodegradation of chlorinated organics (EPA, 1998). Monitoring well, MW-8,
received a score of 17, which indicates there is limited to strong evidence for anaerobic biodegradation of
chlorinated organics (EPA, 1998). Monitoring wells MW-2, MW-3, MW-7, MW-10D, and MW-11S received scores
of 11,11,9,13, and 7, respectably, which indicate limited evidence of anaerobic degradation of chlorinated
February 2024 31404568.018

organics (EPA, 1998). Monitoring well MW-5 (i.e., the background well) was not sampled during this event due to
an inadequate volume of groundwater. The natural attenuation screening protocol forms are included in
Appendix C.
Based on the results of the screening protocol, there is evidence that anaerobic natural attenuation is occurring at
the site. Therefore, modeling was performed on the second semi-annual 2023 data to simulate remediation by
natural attenuation using the BIOCHLOR screening model (EPA, 2000). Because three plumes with NC 2L
Standard exceedances were identified in the NES, each plume was modeled separately. However, the north
plume was not modeled during this event because tetrachloroethene, trichloroethene, dichloroethene (e.g., cis-
and trans-), and vinyl chloride were not detected in samples collected from MW-2 and MW-11S. Modeling
parameters for advection, dispersion, and modeled area were the same as previous models performed for the
site. A 42-year simulation period was selected for the model, representing the time at which waste was first
placed in the landfill (i.e., the original source): it is assumed that waste was first accepted in 1981 per the
approved CAP (Golder, 2015).
The second semi-annual 2023 results represent current conditions at the facility and therefore, the models were
calibrated to the current sample results by adjusting the biotransformation data within a prescribed range specified
by literature values within the BIOCHLOR program. Once the models were calibrated, a forecasted model was
created by changing the simulation period to 100 years to assess the size of the contaminant plume in the future.
BIOCHLOR generates plots that compare concentrations of tetrachloroethene, trichloroethene, dichloroethene,
vinyl chloride, and ethene over time with no degradation to concentrations where sequential 1st order decay is
occurring. The plots are provided in Appendix C. The centerline plots can be used to forecast the contaminant
plume size over time.
For the plume located northeast of the waste unit, analytical data for samples collected from MW-8 and MW-3
were modeled and are presented in Appendix C on Figures C-9 and C-10. Vinyl chloride and ethene were not
detected in samples collected from MW-8 and tetrachloroethene, trichloroethene, dichloroethane, vinyl chloride,
and ethene were not detected in samples collected from MW-3. Cis-1,2-dichloroethene detected in samples
collected from MW-8 plot on or below their respective 1st order sequential decay curves. The cis-1,2-
dichloroethene variety was the prominent form of dichloroethene, indicating that the detections represent daughter
products of tetrachloroethene and/or trichloroethene. The results from these plots indicate that natural attenuation
is occurring in the northeast plume. According to the current data and as indicated by the BIOCHLOR model, it is
likely that the plume size has stabilized.
For the plume located west of the waste management unit, analytical data for samples collected from MW-10S,
MW-10D, and SW-2 were modeled and are presented in Appendix C on Figures C-11 and C-12. Ethene was
not detected in samples collected from MW-10S; tetrachloroethene and trichloroethene were not detected in
samples collected from MW-10D; and tetrachloroethene, trichloroethene, dichloroethene, vinyl chloride, and
ethene were not detected in samples collected from SW-2. The concentrations of tetrachloroethene and
dichloroethene in samples collected from MW-10S plot below their respective 1st order sequential decay curve.
The cis-1,2-dichloroethene isomer was again the prominent form of dichloroethene, indicating that the detections
represent daughter products of tetrachloroethene and/or trichloroethene. Concentrations or vinyl chloride and
ethene in samples collected from MW-10D plot below their respective 1st order sequential decay curve. The
results from these plots indicate that natural attenuation is occurring in the western plume.
According to the current data and as indicated by the BIOCHLOR model, it is likely that the plume size has
stabilized. Because of the low concentration of parent compounds and multiple degradation pathways for cis-1,2-

dichloroethene (aerobic and anaerobic), there are limited concentrations of vinyl chloride and ethene in each of
the plumes evaluated. The concentration trends show that cis-1,2-dichloroethene is not accumulating and that
degradation of the chlorinated compounds is continuing.
The samples collected from MW-2, MW-3, MW-10D, and MW-11S were also analyzed for a reduced list of COCs
as identified in the CAP, which included benzene, 1,1-dichloroethane, tetrachloroethene, trichloroethene, and
vinyl chloride. As presented, these constituents were also analyzed in samples collected from the compliance
monitoring wells as part of the routine semi-annual water quality monitoring event. A summary of the COC results
from the performance monitoring wells as well as the compliance monitoring wells is included in Table 9, and the
laboratory certificates-of-analyses are included in Appendix B.
1,1-Dichloroethane, tetrachloroethene, benzene, and vinyl chloride were detected at a quantified concentration
above the PQL and the NC 2L Standard in samples collected from one or more downgradient monitoring wells
during the second semi-annual 2023 sampling event. No other COCs were detected above the NC 2L Standards
in samples collected from the corrective action monitoring wells during this sampling event.
5.0 CONCLUSIONS
The results of the second semi-annual water quality monitoring event of 2023 show continued evidence of natural
attenuation of VOCs in groundwater at the site. Evidence suggests that MNA continues to be a viable remedy.
However, due to the continued presence of VOCs above applicable groundwater standards, the Randolph County
Landfill will continue to be monitored in accordance with the requirements of the Assessment Monitoring Program
as outlined in Title 15A NCAC 13B .1634. The next compliance and MNA monitoring event for this facility is
tentatively scheduled for May 2024.

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.
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.

GLOSSARY OF TERMS
Guide to Reading and Understanding Your Laboratory Report
The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not
intended as a comprehensive explanation, and if you have additional questions please contact your project representative.
Results Disclaimer - Information that may be provided by the customer, and contained within this report, include Permit Limits, Project Name,
Sample ID, Sample Matrix, Sample Preservation, Field Blanks, Field Spikes, Field Duplicates, On-Site Data, Sampling Collection Dates/Times, and
Sampling Location. Results relate to the accuracy of this information provided, and as the samples are received.
Abbreviations and Definitions
MDL Method Detection Limit.
RDL Reported Detection Limit.
Rec.Recovery.
RPD Relative Percent Difference.
SDG Sample Delivery Group.
U Not detected at the Reporting Limit (or MDL where applicable).
Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes
reported.
Dilution
If the sample matrix contains an interfering material, the sample preparation volume or weight values differ from the
standard, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the
laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the
result reported has already been corrected for this factor.
Limits
These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal
for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or
duplicated within these ranges.
Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control
sample. The Original Sample may not be included within the reported SDG.
Qualifier
This column provides a letter and/or number designation that corresponds to additional information concerning the result
reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and
potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.
Result
The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was
no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL”
(Below Detectable Levels). The information in the results column should always be accompanied by either an MDL
(Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect
or report for this analyte.
Uncertainty
(Radiochemistry)Confidence level of 2 sigma.
Case Narrative (Cn)
A brief discussion about the included sample results, including a discussion of any non-conformances to protocol
observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will
be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.
Quality Control
Summary (Qc)
This section of the report includes the results of the laboratory quality control analyses required by procedure or
analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not
being performed on your samples typically, but on laboratory generated material.
Sample Chain of
Custody (Sc)
This is the document created in the field when your samples were initially collected. This is used to verify the time and
date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This
chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the
samples from the time of collection until delivery to the laboratory for analysis.
Sample Results (Sr)
This section of your report will provide the results of all testing performed on your samples. These results are provided
by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for
each sample will provide the name and method number for the analysis reported.
Sample Summary (Ss)This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and
times of preparation and/or analysis.
Qualifier Description
B The same analyte is found in the associated blank.
J The identification of the analyte is acceptable; the reported value is an estimate.
J6 The sample matrix interfered with the ability to make any accurate determination; spike value is low.
T8 Sample(s) received past/too close to holding time expiration.

NTT Trip, field and/or equipment, and laboratory blank results have all been reported. All detects for blanks are listed below by constituent. All laboratory method blanks, if any, have been ‘flagged’ with a ‘B’ where detected in other samples as appropriate and a laboratory narrative was provided. If the sample was flagged by the laboratory and is not within 5X of the concentration in the blank (or 10X for commonly detected laboratory contaminants-acetone, methylene chloride and phthalates), list
below with explanation if flags should be removed. If flags need to be added for samples, also list below. NTT It is clear from the laboratory report that samples have or have not been diluted during analysis, and if the samples have been diluted, the result is reported as a multiple of the dilution (e.g., a sample diluted 10x resulting in an analytical detection of 1.0 should be reported as 10). Those that
have been diluted are listed below with the dilution factor.
 Volatile Fatty Acids
• MW-2, MW-10S, MW-10D (10X)
 Ferrous Iron
• MW-3 (5X); MW-2 (2X)
 BOD
• MW-3, MW-10D (3X); MW-2, MW-7, MW-8, MW-10S, MW-11S (1.5X) NTT The report provides the reporting limit for each constituent.
NTT The results were reported at or below their proper reporting limits. Those that are not reported correctly are listed below (by constituent) with the proper reporting limit listed beside them. State if the reporting limit error is due to dilutions. NTT No organic constituents were reported above their respective reporting limits, and no inorganic or
organic constituents were reported above their respective NC 2L Drinking Water Standards/NC 2L IMAC in wells, field/equipment/trip blanks, or above applicable surface water standards in surface water points. Those that were detected above applicable groundwater/surface water standards are listed below.
 1,1-Dichloroethane (2L = 6 ug/L)

NTT Laboratory analyzed at least one internal blank for each method, where applicable. NTT Laboratory blank is interference-free. NTT Surrogate recoveries are provided for each analytical method, where applicable.
NTT Surrogate recoveries for each method are within the acceptable limits (i.e., at least 50% of the surrogates were within range). NTT MS/MSD/LCS data results are provided for each analytical method.
NTT MS/MSD/LCS recoveries for each method are within the acceptable limits (i.e., at least 1 of the 3 were within range). GC/MS VOA, Method 8260D
 Method 8260D SIM 14D: The continuing calibration verification (CCV) analyzed in batch 680-806737 was outside the method criteria for the following analyte(s): 4-Bromofluorobenzene (Surr). A CCV standard at or below the reporting limit (RL) was analyzed with the affected samples and found to be acceptable. As indicated in the reference method, sample analysis may proceed; however, any detection for the affected analyte(s) is considered estimated.
 Method 8260D: The RPD of the laboratory control sample (LCS) and laboratory control sample duplicate (LCSD) for analytical batch 752-5123 recovered outside control limits for the following analytes: Bromochloromethane.
 Method 8260D: The CCV for analytical batch 752-5123 recovered outside control limits for the following analyte(s): Acrylonitrile . Acrylonitrile has been identified as a poor performing analyte when analyzed using this method; therefore, re-extraction/re-analysis was not performed. These results have been reported and qualified.
 Method 8260D: The matrix spike/matrix spike duplicate (MS/MSD) for analytical batch 752-5093 exceeded control limits for the following analyte(s): 1,2-Dibromo-3-Chloropropane and 2-Butanone (MEK), Note that this analyte is a known poor performer when analyzed using this method.
 Method 8260D: The CCV for analytical batch 752-5093 recovered outside control limits for the following analyte(s): Acrylonitrile,Bromomethane and Iodomethane . These compounds have been identified as a poor performing analytes when analyzed using this method; therefore, re-extraction/re-analysis was not performed. These results have been reported and qualified.

4.0 ANALYTE LISTS/METHODS
NTT The proper number of constituents are present for each analyte list as identified above (including detects where applicable).
WSP USA INC QUALITY ASSURANCE & QUALITY CONTROL LABORATORY DATA REVIEW Page 3 of 4 JS Proper EPA SW-846 analytical methods were used for analysis.
5.0 DATA REPORTING JS All analytical reporting associated with the event was performed by the contracted lab. JS Trip, field and/or equipment, and laboratory blank results have all been reported. All detects for blanks
are listed below by constituent. All laboratory method blanks, if any, have been ‘flagged’ with a ‘B’ where detected in other samples as appropriate and a laboratory narrative was provided. If the sample was flagged by the laboratory and is not within 5X of the concentration in the blank (or 10X for commonly detected laboratory contaminants-acetone, methylene chloride and phthalates), list below with explanation if flags should be removed. If flags need to be added for samples, also list below.

 Trip Blank – Chloroform @ 0.205 (J)
• MW-8 @ 0.181 ug/L (J). B flag added.
• SW-3 @ 0.725 ug/L (J). B flag added.
• SW-4 @ 0.733 ug/L (J). B flag added.
 Method Blank – Methylene Chloride @ 0.2518 (J)
• MW-10s @ 0.241 ug/L (J). B flag added JS It is clear from the laboratory report that samples have or have not been diluted during analysis, and if the samples have been diluted, the result is reported as a multiple of the dilution (e.g., a sample
diluted 10x resulting in an analytical detection of 1.0 should be reported as 10). Those that have been diluted are listed below with the dilution factor.
JS The report provides the reporting limit for each constituent.
JS The results were reported at or below their proper reporting limits with the proper reporting limit listed
beside them. State if the reporting limit error is due to dilutions.
NTT No organic constituents were reported above their respective detection limits, and no inorganic or organic constituents were reported above their respective NC 2L Drinking Water Standards/GWPS
in wells, or field/equipment/trip blanks, or above applicable surface water standards in surface water points.
