1.0 INTRODUCTION
1.1 Site Information
On behalf of Rockingham County, LaBella Associates, PC (LaBella) has prepared this Water Quality
Monitoring Report for the Rockingham County Solid Waste Management Facility (the Facility). The
Facility is owned by Rockingham County (the County) and operated by Wall Recycling, LLC (Wall) and
is operating under North Carolina Solid Waste Permit Nos. 79-01 and 79-04. The Facility is located at
281 Shuff Road in Madison, Rockingham County, North Carolina. The property boundary is shown on
a portion of the 7.5-minute United States Geological Survey (USGS) topographic map for the Bethany
and Southwest Eden, North Carolina quadrangles (Figure 1). The property is surrounded by rural
wooded areas and farmland.
The Rockingham County Solid Waste Management Facility consists of two landfills: a closed, unlined
municipal solid waste (MSW) landfill and an active Subtitle D MSW landfill. The closed MSW landfill
operated under Permit 79-01 and is comprised of five areas, referred to as Areas I, II, III, IV (collectively
referred to as Areas I-IV), and Area V. Areas I-IV all closed before October 9, 1993. Area V closed after
October 9, 1993. The active Subtitle D MSW landfill is comprised of four contiguous cells, designated
Phases 1, 2, 3, and 4, and is operated under Permit 79-04.
1.2 Site Geology
The Facility is located in the Piedmont physiographic province within the Milton Belt, which contains
schist and gneiss of amphibolite facies, with minor areas of granitic intrusive rock (Carpenter, 1982).
Carpenter mapped bedrock in the vicinity of the site as biotite gneiss and schist, locally interlayered
with hornblende gneiss and schist and felsic gneiss. Map patterns and outcrop information for the
Milton Belt indicate that the metamorphic rock is broadly folded, with foliation of moderate to gentle
dips. Strikes for outcrops are variable, owing to the generally flat-lying nature of the geologic structure;
the regional strike is to the east-northeast (Carpenter, 1982).
Triassic diabase dikes mapped in the region are based on aeromagnetic surveys. Occasional outcrops
have consistent strikes of approximately 10 to 20 degrees west of north. Quaternary alluvium is
mapped in the larger drainages in the site vicinity, including Jacob’s Creek and its tributaries.
The water table typically reflects topography, and groundwater flows from the higher topography
(recharge areas) to the valleys where it discharges to Little Jacobs Creek, which borders the southeast
side of the Facility. Little Jacobs Creek and its unnamed tributaries are classified as “Class C” for
waters protected for uses such as secondary recreation, fishing, wildlife, fish consumption, aquatic life
including propagation, survival and maintenance of biological integrity, and agriculture.
1.3 Regulatory Status
Areas I-IV (Permit 79-01) were closed before the implementation of Resource Conservation and
Recovery Act (RCRA) Subtitle D requirements. The landfill is currently monitoring groundwater following
criteria outlined in Rule .0500 of the North Carolina Solid Waste Management Regulations (NCSWMR
- 15A NCAC 13B) for municipal solid waste landfills (MSWLF) closed before October 9, 1993. Area V
groundwater monitoring is completed in accordance with NCSWMR § .1633 (Detection Monitoring
Program).

The Subtitle D Landfill (Permit 79-04) groundwater monitoring program entered Assessment
Monitoring per 15A NCAC 13B .1634 in 2017; however, in a letter dated March 22, 2018, the North
Carolina Department of Environmental Quality – Solid Waste Section (NCDEQ-SWS) authorized
Rockingham County to return all the Subtitle D Area monitoring wells, except for monitoring wells
7904-MW-19 and 7904-MW-19R, to Detection Monitoring. Monitoring well 7904-MW-19 became a
performance well and monitoring well 7904-MW-19R stayed in Assessment Monitoring. Surface water
monitoring is performed following NCSWMR § .0602.
2.0 FACILITY MONITORING PROGRAMS
The monitoring program at the Facility is completed as required by the NCSWMR. The current
groundwater monitoring programs for each of the landfills, surface water, and the leachate storage
system are included in LaBella’s April 2021 Water Quality Monitoring Plan (WQMP). The September
2024 Monitoring Event was conducted in accordance with the April 2021 WQMP, and the monitoring
program is presented below.
2.1 Closed Landfill Areas I-IV Monitoring Program
There are nine groundwater monitoring wells associated with Areas I-IV. Monitoring well 7901-MW-4A
is the upgradient background well. Monitoring wells 7901-MW-6, 7901-MW-7, 7901-MW-12S,
7901-MW-12D, 7901-MW-13S, and 7901-MW-13D are monitored as compliance wells. Monitoring
wells 7901-MW-3A and 7901-MW-8 are used to obtain groundwater levels. All wells are sampled
semiannually, except 7901-MW-12S and 7901-MW-12D, which are sampled biennially and were not
sampled during this monitoring event. Both wells will be sampled in 2025.
Groundwater samples are collected semiannually and analyzed for all constituents listed in 40 CFR
Part 258, Appendix I, incorporated by reference into the NCSWMR (North Carolina (NC) Appendix I) and
1,4-dioxane. On July 23, 2024, NCDEQ approved a reduction in sampling for 1,4-dioxane for
monitoring wells MW-4A, MW-12S, MW-12D, MW-13S, and MW-13D. These wells will no longer be
monitored for 1,4-dioxane; however, monitoring wells MW-6 and MW-7 will continue to be sampled for
1,4-dioxane.
The following table summarizes the Areas I-IV monitoring well classifications and monitoring zones.
The well locations are shown on Drawing 1 and a summary of well construction details is included in
Appendix 1.

2.2 Closed Landfill Area V Monitoring Program
The current groundwater monitoring network at the Closed Landfill Area V consists of one upgradient
background well (7901-MW-1A) and three downgradient wells (7901-MW-5, 7901-MW-9, and
7901-MW-11). In addition, monitoring well 7901-MW-2A is used as an observation well. Please note
that there are two monitoring wells designated MW-11 at the Facility: one associated with Area V
(Permit 79-01) and one associated with the Subtitle D Landfill (Permit 79-04). The monitoring well
associated with Area V is referred to as 7901-MW-11 and the monitoring well associated with Subtitle
D Landfill is referred to as 7904-MW-11.
Groundwater samples are collected semiannually and analyzed for all constituents listed in NC
Appendix I and for 1,4 dioxane. Monitoring wells 7901-MW-9 and 7901-MW-11 are also monitored for
detected Appendix II constituents (mercury and tin) and monitoring well 7901-MW-9 is analyzed for
dichlorodifluoromethane. On July 23, 2024, NCDEQ approved a reduction in sampling for 1,4-
dioxane for monitoring wells MW-1A, MW-11, and NES-1. These wells will no longer be
monitored for 1,4-dioxane; however, monitoring wells MW-5 and MW-9 will continue to be
sampled for 1,4-dioxane. Monitoring well classification and monitoring zones are summarized
below. The well locations are shown on Drawing 1 and a summary of well construction details is
included in Appendix 1.
Nature and extent well 7901-NES-1 was installed in 2004 in response to exceedances observed in
several wells associated with this area and was monitored until June 2010, when monitoring of this
well was suspended. In a letter dated March 22, 2018, the NCDEQ-SWS requested Rockingham
County to resume monitoring of 7901-NES-1.

2.3 Subtitle D Landfill Monitoring Program
Twenty-five active groundwater monitoring wells comprise the monitoring network at the Rockingham
County Subtitle D Landfill. The current compliance monitoring well network is listed in the table below
and the approximate locations are depicted in Drawing 1. A summary of well construction details is
included in Appendix 1.
The Subtitle D Area’s monitoring wells, except for monitoring wells 7904-MW-19 and 7904-MW-19R,
are monitored under Detection Monitoring. Groundwater samples are collected semiannually and
analyzed for all constituents listed in NC Appendix I and 1,4-dioxane. On July 23, 2024, NCDEQ
approved a reduction in sampling for 1,4-dioxane for monitoring wells MW-1S, MW-1D, MW-3, MW-4,
MW-5D, MW-7D, MW-8, MW-9, MW-10D, MW-11, MW-12, MW-13D, MW-14, MW-15, MW-16S, MW-

16D, MW-17S, MW-17D, MW-21R, and MW-23R. These wells will no longer be monitored for 1,4-
dioxane; however monitoring wells MW-2 and MW-6 will continue to be sampled for 1,4-dioxane.
Monitoring well 7904-MW-19R is monitored under Assessment Monitoring and samples from this
monitoring well are analyzed for the full NCSWMR Appendix II list annually (during the first semiannual
event of each year). Also, it is analyzed for the NCSWMR Appendix I list plus detected NCSWMR
Appendix II constituents during the second semiannual event of each year. On July 23, 2024, NCDEQ
approved a reduction in sampling for 1,4-dioxane for monitoring wells MW-19 and MW-19R. These
wells will no longer be monitored for 1,4-dioxane. In addition, monitoring well 7904-MW-19R samples
are analyzed for methane, ethane, ethene, and dissolved carbon dioxide during both semiannual
events. Monitoring well 7904-MW-19 is a corrective action performance well and is sampled for the
Facility’s list of constituents of concern (COC). The current COC list includes:
• Benzene,
• 1,2-Dichloroethane,
• Vinyl Chloride,
• Arsenic, and
• Cobalt.
On March 6, and 7, 2019, monitoring wells 7904-MW-20S, 7904-MW-20D, 7904-MW-21, and
7904-MW-23 were abandoned to allow for the construction of a new cell (Phase 4). On March 11 and
12, 2019, monitoring wells 7904-MW-21R and 7904-MW-23R were installed as a part of the
compliance network and are monitored under Detection Monitoring.
During the summer of 2020, the Facility completed a hydrogeological study as part of the Life-of-Site
(LOS) Application for future Phases 5 through 7. The hydrogeological study included the installation of
five groundwater monitoring wells (7904-MW-24 through 7904-MW-28), which are now part of the
Subtitle D landfill’s monitoring network. Groundwater samples from these monitoring wells were
analyzed for all constituents listed in NC Appendix I and for 1,4-dioxane as part of the monitoring well
baseline sampling. These wells were not sampled during the September 2024 Monitoring Event.

2.4 Surface Water Monitoring Program
The surface water monitoring program at the Facility is performed in accordance with the NCSWMR
and the approved April 2021 WQMP. Surface water samples are collected semiannually and analyzed
for the constituents listed in NC Appendix I and for 1,4-dioxane. On July 23, 2024, NCDEQ approved a
reduction in sampling for 1,4-dioxane for surface water monitoring points SMP-1, SMP-3, and SMP-4.
These locations will no longer be monitored for 1,4-dioxane; however, surface monitoring location
SMP-2 will continue to be sampled for 1,4-dioxane. The surface water monitoring network includes
one upstream surface water sampling point (SMP-3) and three downstream surface water monitoring
points (SMP-1, SMP-2, and SMP-4). These monitoring points are located along minor tributaries to
Little Jacobs Creek. Little Jacobs Creek, which borders the southeast side of the Facility, is classified
as Class C for freshwater aquatic life and secondary recreation. Surface water monitoring point
classification is summarized below. The approximate locations of the surface water monitoring points
are shown in Drawing 1.

2.5 Leachate Monitoring Program
The Leachate Lagoon Monitoring Point (7904-LMP-1) is sampled at the Facility on a semiannual basis.
The approximate location of 7904-LMP-1 is shown in Drawing 1. The following constituents are
required for laboratory leachate analysis:
• NC Appendix I Metals,
• NC Appendix I Volatiles,
• 1,4-Dioxane,
• Total Suspended Solids (TSS),
• Biochemical Oxygen Demand (BOD),
• Chemical Oxygen Demand (COD,
• Total Phosphorus,
• Nitrate as N, and
• Sulfate.
3.0 SEPTEMBER 2024 MONITORING EVENT
3.1 Field Work
LaBella personnel visited the Facility on September 9-12, 2024, (September 2024 Monitoring Event)
to obtain water levels to the nearest 0.01-foot, purge, and sample monitoring wells in the compliance
network at Areas I-IV, Area V, and Subtitle D Landfills.
Four surface water monitoring points and one leachate monitoring point were also sampled during the
September 2024 Monitoring Event. In addition, depth-to-water measurements were obtained at
monitoring wells 7901-MW-3A, 7904-MW-8, 7904-MW-9, 7904-MW-22, 7904-MW-24, 7904-MW-25,
7904-MW-26, 7904-MW-27, and 7904-MW-28.
Monitoring wells were purged and sampled using disposable bailers or a 12-volt submersible pump
during the September 2024 Monitoring Event. The 12-volt submersible pump was decontaminated
with Alconox liquid detergent and deionized water after each monitoring well that required the use of
the pump.
Measurements of temperature, pH, specific conductivity, dissolved oxygen, oxidation-reduction
potential, and turbidity were recorded before purging, after each purge volume, and during sampling.
Copies of the groundwater sampling logs are included in Appendix 2. Prior to sampling, laboratory-
supplied containers were prepared with the following information:
• Monitoring well number (completed by field personnel);
• Date and time of sample collection (completed by field personnel);
• Initials of sampling personnel (completed by field personnel);
• Project name and number (completed by the laboratory),
• Chemical preservative (completed by the laboratory); and

______________________________________________________________________________________________
Rockingham County Solid Waste Management Facility, LaBella Associates
Permit Nos. 79-01 & 79-04 January 2025
September 2024 Water Quality Monitoring Report
7
• Requested chemical analysis (completed by the laboratory).
During the monitoring event, groundwater samples from each sampled monitoring well were collected
directly from the bailers or from the pump discharge tubing and transferred to the provided laboratory
containers within 24 hours of the final purge volume. Immediately after collection, the samples were
placed in a laboratory-provided cooler and chilled on ice.
Surface water samples 7904-SMP-1 through 7904-SMP-4 were collected directly from streamflow by
lowering the prepared sample containers into the stream. Care was taken not to overflow the sample
containers (which could lead to preservative loss) and to avoid sampling-induced turbidity. At the time
of sampling, surface water was also measured for temperature, pH, specific conductivity, dissolved
oxygen, oxidation-reduction potential, and turbidity. Copies of the surface water sampling logs are
included in Appendix 2. After collection, the samples were placed in a laboratory-provided cooler and
chilled on ice.
Leachate samples were collected from the leachate lagoon by lowering a disposable bailer into the
lagoon and then dispensing the leachate into laboratory-prepared sample containers. At the time of
sampling, leachate was measured for temperature, pH, specific conductivity, dissolved oxygen,
oxidation-reduction potential, and turbidity. The prepared sample containers were then placed in a
cooler and chilled on ice.
3.2 Laboratory Analysis and Quality Control
The collected groundwater, surface water, and leachate samples were submitted to Eurofins
Environmental Testing (Eurofins) of Cary, North Carolina under chain-of-custody control for analysis.
LaBella requested a Level II data report for the final laboratory reports. According to the laboratory’s
sample condition and verification reports, the samples were received by the laboratory on September
13, 2024, in good condition, properly preserved, and within analysis hold times.
An equipment blank was collected by LaBella personnel as part of the monitoring event. To collect the
equipment blank, laboratory-provided deionized water was run through the decontaminated 12-volt
submersible pump, and the samples were collected directly from the pump discharge tubing. A field
blank was collected using laboratory-supplied distilled water exposed to the sampling environment
during the September 2024 Monitoring Event. A trip blank was also prepared by the laboratory to
accompany the volatile sampling containers during shipment. The equipment blank and field blank
were analyzed for NC Appendix I constituents, mercury, tin, trichlorofluoromethane, and 1,4-dioxane,
while the trip blank was analyzed for NC Appendix I volatile organic compounds,
trichlorofluoromethane, and 1,4-dioxane.
Upon receipt of complete laboratory data packages on September 20, September 23, and September
26, 2024, LaBella personnel reviewed the data for the following:
• General typographical errors,
• Correct analyses performed and within method specified hold times,
• Biased data results based on Surrogate Recoveries, Matrix Spike, Matrix Spike
Duplicate, and Laboratory Control Samples,
• Blank-qualified data (B-flags),
• Detections above the Method Reporting Limits (MRL),

4.0 HYDROGEOLOGY
Depth to groundwater was measured in each monitoring well at the site before purging. The
groundwater elevation at each well was calculated relative to the surveyed measuring point (top of
casing) for each monitoring well. Table 1 summarizes the groundwater elevations.
Groundwater elevation contours were interpreted from water level data obtained during the
September 2024 Monitoring Event and a potentiometric surface map was created. The potentiometric
surface contours for groundwater are shown in Drawing 1. Based on LaBella’s interpretation, the
groundwater flow paths across the Facility appear to converge on the streams that bisect the site and
border it to the west-northwest. Groundwater flow beneath the closed Area I-IV Landfills is
predominantly to the south. Groundwater flow beneath the closed Area V landfill is predominantly to
the southwest. Conversely, groundwater flow beneath the Subtitle D Area Landfill is radial from the
southeast to the southwest and west.
Horizontal groundwater gradients were estimated based on the September 2024 groundwater
contours. Groundwater gradients were estimated from groundwater flow arrow segments that
intersect potentiometric surface contours (see Drawing 1). These gradients are summarized in Table 2.
The horizontal gradients were calculated as approximately 0.043 for Closed Areas I-IV, 0.045 for
Closed Area V, and 0.036 for the Subtitle D area.
The average hydraulic conductivity (k) estimates from individual well slug tests (CDM, 1996; JOYCE,
2007; LaBella, 2021) were used to estimate average linear groundwater flow velocities for each area.
Hydraulic conductivities of 1.28 feet per day (ft/day), 1.60 ft/day, and 1.49 ft/day were used for Areas
I-IV, Area V, and the Subtitle D Area, respectively. Effective porosity was estimated at 0.20 for saprolite
and 0.05 for fractured bedrock (CDM, 1996). Linear groundwater flow velocities for wells screened in
saprolite were computed using the following modified Darcy equation:
V = ki/n,
where
V = average linear velocity (ft/day),
k = hydraulic conductivity (ft/day),
i = horizontal hydraulic gradient, and
n = effective porosity.

As shown in Table 2, the linear groundwater flow velocity estimates are approximately 0.28 ft/day in
Areas I-IV, 0.36 ft/day in Area V, and 0.27 ft/day in the Subtitle D area. These ranges are consistent
with previously estimated values (CDM, 1996; JOYCE, 2007; LaBella, 2021).
The linear velocity equation and resulting rates make the simplified assumptions of a homogeneous
and isotropic aquifer. Site boring logs indicate that saprolite sampled at the site often exhibited
remnant foliation and other parent rock textures. These characteristics can impact locally anisotropic
groundwater flow directions. The saprolite and bedrock are hydraulically connected, but effective
porosity typically declines markedly downward into underlying fractured bedrock (Harned, 1989).
5.0 DATA ANALYSIS AND STATISTICAL RESULTS
Analytical results from the September 2024 Monitoring Event were received on September 20,
September 23, and September 26, 2024, from Eurofins. The analytical reports are included in
Appendix 3.
Statistical comparisons of baseline monitoring data to compliance groundwater data are optional
[NCSWMR .1632(g), (h), and (i)] for the Detection Monitoring wells at the Area V and Subtitle D
Landfills. Statistical methods used to evaluate the data from Area V Landfill and Subtitle D Landfill
are discussed in the following sections, if needed. This is done to compare the results of the current
monitoring event to background data. For the September 2024 Monitoring Event, the laboratory
analytical results were compared directly to the NC2L standards or previously approved background
values; therefore, statistical calculations were not required.
5.1 Analytical Results and Comparisons to Standards
5.1.1 Permit 79-01
5.1.1.1 Closed Landfill Areas I-V Detections
The constituents listed in Table 3 were detected at concentrations above the method detection limit
(MDL) during the September 2024 Monitoring Event. Detections above the approved background
concentration or NC2L Standard are shown in Table 4.
The historical inorganic and organic analytical results for Areas I-IV are included in Table A4-1
(Appendix 4). The September 2024 Monitoring Event field parameters are summarized in Table 5.
The analytical results as reported by the laboratory, the laboratory quality assurance/quality control
information, and the chains of custody are included in Appendix 3.
The Facility has an approved Alternate Source Demonstration (ASD) for cobalt and arsenic, with an
addendum dated August 30, 2018, which established a cobalt background concentration of 34.6
micrograms per liter (µg/L) and an arsenic background concentration of 14.08 µg/L; therefore, these
concentrations are used as the groundwater protection standards for cobalt and arsenic, respectively.
5.1.1.2 Closed Landfill Areas I-V Exceedances
After comparing the detected constituents to their respective background concentration or NC2L
standard, it was determined that the following parameters were in exceedance of their respective
standard:
• 1,4-Dioxane (7901-MW-6, 7901-MW-7, 7901-MW-9)
• Benzene (7901-MW-6, 7901-MW-7, 7901-MW-9)

• 1,4-Dichlorobenzene (7901-MW-9)
• Tetrachloroethene (7901-MW-11)
• Vinyl Chloride (7901-MW-6, 7901-MW-9, 7901-MW-11)
Detections above the background concentration or NC2L are shown in Table 4.

5.1.2 Permit 79-04
5.1.2.1 Subtitle D Landfill Detections
The constituents listed in Table 3 were detected above the MDL in groundwater during the September
2024 Monitoring Event for the Subtitle D Landfill. The Facility has an approved ASD for arsenic and
cobalt, with an addendum dated August 30, 2018, which established background concentrations of
14.08 µg/L and 34.6 µg/L, respectively.
The historical inorganic and organic analytical results for the Subtitle D Landfill are summarized in
Table A4-3 (Appendix 4). Field parameters for the September 2024 Monitoring Event are summarized
in Table 5. The analytical results, as reported by the laboratory, the laboratory quality
assurance/quality control information, and the chains of custody are included in Appendix 3.
5.1.2.2 Subtitle D Landfill Exceedances
Detections above the background concentration or NC2L are shown in Table 4. The only constituents
with confirmed exceedances of their respective background concentrations or NC2L standards
include:
• Arsenic (7904-MW-17D)
• Beryllium (7904-MW-2)
• Cobalt (7904-MW-19 and 7904-MW-19R)
The above analytes were detected above their respective NC2L standards or their approved
background concentrations; however, the results are consistent with historical data.
Groundwater remediation consisting of landfill gas extraction is ongoing to reduce cobalt levels in
7904-MW-19 and 7904-MW-19R to background levels. During the partial closure of Phases 1 to 3 of
the Subtitle D landfill, which disrupted the operation of the remedial system, an increase in cobalt
concentration was observed (see Table A4-3).
5.1.3 Surface Water
There were no inorganic or organic constituents detected at quantified concentrations above NC2B or
ISTV standards during the September 2024 Monitoring Event. Please note that estimated
concentrations below the MRL are not considered exceedances of the standard, even if the estimated
value is higher than the standard. Table 3 includes the constituents detected in surface water above
the MDL during the September 2024 Monitoring Event. The historical inorganic and organic analytical
results for surface water are summarized in Table A4-4 (Appendix 4). Field parameters for the
September 2024 Monitoring Event are summarized in Table 5. The analytical results as reported by
the laboratory, the laboratory quality assurance/quality control information and the chains of custody
are included in Appendix 3.

5.1.4 Leachate
Table 3 includes the constituents detected in the leachate sample 7904-LMP-1 above the MDL during
the September 2024 Monitoring Event. The historical inorganic and organic analytical results for the
leachate are summarized in Table A4-5 (Appendix 4). The results, as reported by the laboratory, the
laboratory quality assurance/quality control information, and the chains of custody are included in
Appendix 3.
5.2 Statistical Results
No new statistical analyses were conducted for this event.
6.0 CONCLUSIONS
6.1 Permit 79-01 - Closed Areas I-V
The only constituents reported above NC2L standards were:
• 1,4-Dioxane (7901-MW-6, 7901-MW-7, 7901-MW-9)
• Benzene (7901-MW-6, 7901-MW-7, 7901-MW-9)
• 1,4-Dichlorobenzene (7901-MW-9)
• Tetrachloroethene (7901-MW-11)
• Vinyl Chloride (7901-MW-6, 7901-MW-9, 7901-MW-11)
These exceedances are generally consistent with historical results. In general, the historical data for
Areas I-IV indicate decreasing trends over time and it appears that the constituent impact area is
limited and is not migrating off-site. This is evident in Chart A5-1 (Appendix 5), as the trend lines for
tetrachloroethene, vinyl chloride, and benzene have a negative slope.
For Area V, the results are less clear. The overall trendline for benzene in MW-9 on Chart A5-2
(Appendix 5) is increasing; however, from February 2010 through September 2015, the benzene
concentrations appear to be decreasing, and after September 2015, the concentrations are erratic.
The overall trendline for tetrachloroethene in 7901-MW-11 on Chart A5-2 (Appendix 5) is effectively
flat; however, tetrachloroethene concentrations appear to be generally decreasing after September
2021. The overall trendlines for vinyl chloride in 7901-MW-9 and 7901-MW-11 on Chart A5-2
(Appendix 5) are increasing; however, after May 2016 the vinyl chloride concentrations fluctuate with
no apparent trends.
Based on the analytical results, the interpretation of the September 2024 Monitoring Event data in
comparison to historical trends, and hydrology and site conditions, Permit 79-01 Closed Areas I-IV and
Closed Area V will continue to be monitored as outlined in Title 15A NCAC 13B .0500 and .1633,
respectively, and the approved WQMP.
6.2 Subtitle D Area
The constituents reported above their respective NC2L standard for the Subtitle D Area are:
• Arsenic (7904-MW-17D)
• Beryllium (7904-MW-2)
• Cobalt (7904-MW-19 and 7904-MW-19R)

The Facility has an approved ASD (August 30, 2018) for cobalt and arsenic, which established a cobalt
background concentration of 34.6 µg/L and an arsenic background concentration of 14.08 µg/L;
therefore, these concentrations are used as the groundwater protection standards for cobalt and
arsenic, respectively. The concentrations of arsenic in 7904-MW-17D (20.4 µg/L) and cobalt in 7904-
MW-19 (117 µg/L) and 7904-MW-19R (177 µg/L) are greater than the site background
concentrations; however, the results are generally consistent with historical data.
As shown in Chart A5-3 (Appendix 5), arsenic concentrations in monitoring well 7904-MW-17D appear
to fluctuate seasonally but have an overall increasing trend, and concentrations of beryllium in 7904-
MW-7D fluctuate around the NC2L standard but show a slightly decreasing trend. Cobalt
concentrations in 7904-MW-17S, 7904-MW-19, and 7904-MW-19R all show increasing trends.
Benzene concentrations in 7904-MW-19 and 7904-MW-19R show decreasing trends.
Based on the analytical results from the September 2024 Monitoring Event, the interpretation of the
data in comparison to historical trends, hydrology, and site conditions, the Subtitle D Landfill will
continue to be monitored as outlined in Title 15A NCAC 13B .1633 and the approved WQMP.

Job Narrative752-24203-1
Analytical test results meet all requirements of the associated regulatory program listed on the Accreditation/Certification SummaryPageunlessotherwisenotedundertheindividualanalysis.Data qualifiers and/or narrative comments are included to explain any
exceptions,if applicable.
Matrix QC may not be reported if insufficient sample is provided or site-specific QC samples were not submitted.In these
situations,to demonstrate precision and accuracy at a batch level,a LCS/LCSD may be performed,unless otherwise
specified in the method.Surrogate and/or isotope dilution analyte recoveries (if applicable)which are outside of the QC window are confirmed
unless attributed to a dilution or otherwise noted in the narrative.
Receipt
The samples were received on 9/13/2024 2:30 PM.Unless otherwise noted below,the samples arrived in good condition,and,
where required,properly preserved and on ice.The temperatures of the 3 coolers at receipt time were 2.7°C,2.9°C and 3.1°C.
GC/MS VOA
Method 8260D:(LCSD 752-8843/6)was biased low for Chloromethane.Chloromethane is a poor recovering compound per this
method.The LCS recovered in a very similar manner,but within the acceptable range.Chloromethane was detected in the MRL
sample;therefore,the data were qualified and reported.(LCSD 752-8843/6)
Method 8260D:The laboratory control sample and/or the laboratory control sample duplicate (LCS/LCSD)for analytical batch
752-8871 recovered outside control limits for the following analyte(s):Chloromethane.Chloromethane has been identified as a
poor performing analyte when analyzed using this method;therefore,re-extraction/re-analysis was not performed.(LCSD752-8871/7)
No additional analytical or quality issues were noted,other than those described above or in the Definitions/Glossary page.
GC VOA
Method RSK_175_CO2:The following sample was improperly preserved in the field:7904-MW19R (752-24203-22).The
preservative used is not compatible with the analytes requested.This does not meet regulatory requirements.The vial was
preserved with hydrochloric acid to a pH of less than 2.This may cause the creation of CO2 from carbon in the water sample.Therefore,some of the CO2 reported for this sample may have been created during preservation and may not be in the original
sample source.Historical data does indicate the presence of CO2 at a lower level at this sampling location
No additional analytical or quality issues were noted,other than those described above or in the Definitions/Glossary page.
Metals
No additional analytical or quality issues were noted,other than those described above or in the Definitions/Glossary page.
