1.0 INTRODUCTION
Golder Associates NC, Inc. (“Golder”) is submitting this Alternate Source Demonstration (ASD) on behalf
of the County in response to a letter received from the North Carolina (NC) Division of Environmental Quality
(DEQ), formerly the NC Department of Environment and Natural Resources, on March 14, 2016, with regard
to the status of the water quality monitoring program at the Moore County landfill, North Carolina Solid
Waste Permit (NCSWP) No. 63-01. In this letter, NC DEQ requested that the County take one of two
actions (presented below) in response to volatile organic compounds (VOCs) detected in samples from the
active construction and demolition (C&D) landfill monitoring wells:
 Establish an assessment monitoring program in accordance 15A NCAC 13B .0545 for the C&D
landfill; or
 Demonstrate that a source other than the C&D landfill caused the contamination by submitting
an ASD report.
In response to this request, the County has elected to submit this ASD to demonstrate that the VOCs
detected within the C&D compliance monitoring network pre-date the C&D landfill operation. In addition,
the data collected since the initiation of corrective action at the landfill in 2005 have supported that the
groundwater impacts observed in the C&D groundwater monitoring network originate from the closed
municipal solid waste (MSW) landfill, which is located directly upgradient of the County’s active C&D landfill.

2.0 SITE HISTORY AND BACKGROUND
The Moore County Landfill (hereafter referred to as the “facility” or the “site”) is situated on approximately
314 acres and contains two solid waste disposal units: the closed MSW landfill (which is located on the
eastern side of the facility and has a waste footprint of approximately 60 acres) and the active C&D landfill
(which is located on the western side of the facility and has a waste footprint of approximately 18 acres).
In accordance with the Water Quality Monitoring Plan (WQMP), dated June 2006, the facility is currently
monitored under title 15A NCAC 13B.600 Rules. At the request of the NNC DEQ, the County voluntarily
commenced a corrective action program and implemented monitored natural attenuation (MNA) as the
remedial strategy at the facility due to VOC groundwater impacts from at the closed MSW landfill in 1996.
The Moore County Landfill is located in southwestern Moore County between the towns of Pinehurst and
Aberdeen, NC, as shown on Figure 1. The facility is bound to the west by Horse Creek and to the north
and south by unnamed tributaries of Horse Creek and a power-line right-of-way that transects the property
represents its eastern MSW disposal boundary. Topographic surface elevations at the facility range from
approximately 460 feet above mean sea level (AMSL) along the eastern portion of the closed MSW landfill
to approximately 350 feet AMSL on the southwestern side of the facility. The site is surrounded
predominately by wooded, agricultural, or rural residential properties.
The Moore County MSW landfill began operation in 1968 and the facility stopped accepting waste prior to
the October 9, 1993, compliance date specified in Title 40 of the Code of Federal Regulation Section 258.1
(40 CFR §258.1). In 1993, a transfer station was constructed adjacent to the Moore County MSW landfill
to handle the County’s MSW stream. In September of 1993, Moore County entered into an agreement with
Uwharrie Environmental, Inc., which later became Republic Services of North Carolina, LLC, granting the
private company operation responsibilities at its transfer station. In addition to the transfer station, after
closure of the MSW landfill in 1993 the County opened a C&D landfill under the existing NCSWP No. 63-01.
The County temporarily stockpiled C&D waste from approximately 1993 to 1996, until the current landfill
C&D landfill was permitted and constructed. The County is currently still managing the C&D waste streams
generated within Moore County and currently operates the C&D landfill, which is located immediately west
and downgradient of the closed MSW landfill. Final closure of the MSW landfill was approved by NC DEQ
in December 1996 and the County expressed their intent to comply with post-closure monitoring in January
1997.
2.1 MSW and C&D Compliance Monitoring History
The MSW landfill was originally monitored by five (5) monitoring wells, which were installed in June 1987.
The original MSW landfill monitoring network consisted of MW-1, MW-2, MW-3, MW-4, and MW-5.
Monitoring wells MW-1, MW-2, MW-3, and MW-4 were used as the downgradient monitoring wells and
MW-5 (side gradient of the MSW landfill) was used as the upgradient well. The five (5) original monitoring

February 2017 3 0739615016.400

g:\projects\moore county\groundwater\2016 asd c&d landfill\final\a_report text\moore co asd for c&d landfill.docx
wells were located with the anticipation of expanding the MSW landfill; however after the promulgation title
15A NCAC 13B.1600 rules, the County made the decision to close the MSW landfill. As discussed, a C&D
landfill was constructed under NCSWP No. 63-01 in 1996. The new C&D landfill utilized monitoring wells
MW-3 and MW-4 (remnants of the MSW landfill’s monitoring network) as downgradient monitoring wells for
the new C&D landfill. In addition to MW-3 and MW-4, monitoring wells MW-6 through MW-9 were installed
and incorporated into the C&D compliance network in March 1995 to monitor the area between the MSW
and C&D landfills.
Due to detections of VOCs in samples from monitoring wells downgradient of the closed MSW landfill and
concerns of off-site migration expressed by the NC DEQ in January 1996, the County voluntarily proceeded
with groundwater corrective action for the MSW facility. In September 1996, additional groundwater
monitoring wells were installed in an effort to delineate the horizontal and vertical extent of groundwater
impacts caused by the closed MSW landfill. The additional monitoring wells installed in September 1996
included MW-11S/D, MW-12S/D, MW-13S/D, MW-14, and MW-15. With the exception of MW-15, the new
groundwater monitoring wells would also serve as additional monitoring wells for the newly constructed
C&D facility. Monitoring wells MW-16S/D were later installed to replace MW-12S/D during an expansion of
the C&D facility. A private water supply well at the Blake residence (PW-1), which is located upgradient of
the facility, was added to the monitoring network in 1996, along with surface water monitoring points (SW-
1 and SW-2). A summary of monitoring well construction information is presented in Table 1.
In a letter dated October 6, 1999, the NC DEQ, in a response to low level VOC detections and exceedances
of methane above the lower explosive limit (LEL) along the northern property boundary, requested that the
County perform a water quality assessment and explosive gas study in accordance with 15A NCAC 13B
.0402(3) to delineate the extent of VOC impacts to groundwater and the possibility of methane gas crossing
the property line. A “Methane and Groundwater Quality Assessment Report” was submitted by HDR with
an addendum to NC DEQ in December of 2000. In this report, a confining unit was identified at depth,
which was reported to limit vertical groundwater contamination. In January 2005, the NC DEQ requested
that the County complete an Assessment of Corrective Measures (ACM) and select a remedy in accordance
with 15A NCAC 2L .0106. HDR submitted the ACM in July 2005 with MNA as the primary proposed remedy
with a contingency plan for active landfill gas (LFG) remediation. The NC DEQ approved the
recommendations in the ACM on November 21, 2005; however, they did not require a public hearing, as
this was not required for this facility under the applicable regulations (HDR, 2005).
A revised WQMP was prepared in July 2006 and approved on October 13, 2006, by the NC DEQ. This
revised WQMP includes monitoring of NC Appendix I VOCs and Resource Conservation Recovery Act
(RCRA) metals for all groundwater and surface water monitoring points, as well as “performance
monitoring” (i.e., MNA) parameters for selected wells. In a letter from the NC DEQ dated April 18, 2008,
the County received permission to eliminate hydrogen, carbon dioxide, and volatile fatty acids from the

February 2017 4 0739615016.400

g:\projects\moore county\groundwater\2016 asd c&d landfill\final\a_report text\moore co asd for c&d landfill.docx
semi-annual monitoring list, and complete groundwater modeling annually. This letter also specified that
the County would collect the full suite of “performance monitoring parameters” in April and October 2011,
and present a MNA corrective action evaluation report (CAER) after completion of the October 2011 water
quality monitoring event (WQME). The CAER was approved in May 2012. The County has currently
completed the second five (5) year MNA compliance cycle at the MSW landfill and will submit the next
CAER now that the October 2016 event has been completed. .
2.2 Hydrogeologic Setting
The facility is located in the inner Coastal Plain physiographic province of NC. The geologic units of this
region are relatively young, dating from the Cretaceous Period to the Tertiary Period. The site is underlain
by sands, silts, and clays of the Middendorf Formation, which generally consist of intercalated, lenticular,
thick-bedded, light-colored sands and clays (mudstones) with local concentrations of clay-clast
conglomerates (Figure 2) (NCGS, 1985 and Sohl, Norman, and James, 1991). Borings at the facility
describe the subsurface mainly as silty sand, poorly sorted sand, and well sorted sand inter-bedded with
discontinuous silt and clay lenses as defined by the Unified Soil Classification System (USCS). The
discontinuous silt and clay lenses varied in thickness form one inch to several feet in facility borings. The
available boring logs for monitoring wells installed at the facility can be found in Appendix A of this report.
A summary of monitoring well construction information is presented in Table 1.
The uppermost groundwater beneath the facility is present in a shallow unconfined aquifer comprised of
sands mixed with thin clay seams and larger seams of fine sand. The uppermost aquifer at the site is
approximately 55 feet thick and underlain by a clay confining layer (HDR, 2005). In general, surface water
and groundwater at the facility flows to the west and southwest toward Horse Creek, which is located along
the western property boundary. Limited surface water and groundwater flows to the north and south to
unnamed tributaries of Horse Creek located along the northern and southern property boundaries (as
shown on Figure 2). Based on available data, the unnamed tributaries of Horse Creek appear to be gaining
or effluent streams that increase in water volume downstream as a result of infiltrating water from the local
aquifer. Groundwater occurs at depths varying from approximately 6 to 34 feet below ground surface across
the site. Historical measurements of groundwater elevations are summarized in Table 2. Groundwater
elevations from the April 2016 monitoring event were used to prepare a groundwater surface contour map
presented as Figure 3.
In April 2005 during the ACM study conducted by HDR, seventeen (17) groundwater monitoring wells
(MW-1, MW-2, MW-3, MW-4, MW-5, MW-6, MW-7, MW-8, MW-9, MW-11S/D, MW-13S/D, MW-14, MW-15,
and MW-16S/D) were used to determine an accurate estimate of hydraulic conductivity for the upper aquifer
sediments at the facility. The hydraulic conductivity was evaluated by performing slug tests, which utilizes
falling and rising head tests to mathematically calculate the hydraulic conductivity of the uppermost aquifer
at the facility. Groundwater flow velocities are calculated for each semi-annual WQME using the calculated

February 2017 5 0739615016.400

g:\projects\moore county\groundwater\2016 asd c&d landfill\final\a_report text\moore co asd for c&d landfill.docx
hydraulic conductivity of 5.59E-3 centimeters per second (cm/s). An effective porosity of 0.35 was selected
for the shallow aquifer at the site based on typical effective porosity values for similar soil types (HDR,
2005). The April 2016 groundwater surface contour map (included as Figure 3) and interpreted flow
directions are generally consistent with previously submitted contour map interpretations for this facility.
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:
Vgw = Ki/ne
where Vgw = average linear velocity (feet/year), K = hydraulic conductivity (feet/year), i = horizontal hydraulic
gradient, and ne = effective porosity.
Using several flow pathway calculations, the estimated linear groundwater flow velocity from the April 2016
WQME had a calculated range of 266 to 360 feet per year, with an average value of 301 feet per year, as
shown on Table 3. The calculated groundwater flow rates from the April 2016 WQME are consistent with
historical calculations of groundwater flow velocities. The linear velocity equation above makes the
simplified assumptions of a homogeneous and isotropic aquifer. Therefore, this equation 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.

3.0 CONSTITUENTS-OF-CONCERN
A summary of historical groundwater detections for the facility’s compliance network are provided as
Table 4. A summary of groundwater field parameters is included as Table 5. Based on the evaluation of
recent groundwater monitoring data for the C&D landfill, the following constituents are considered to be
constituents-of-concern (COCs) and are addressed in this ASD:
 acetone
 benzene
 chlorobenzene
 chloroethane
 1,2-dichlorobenzene
 1,4-dichlorobenzene
 1,1-dichloroethane
 cis-1,2-dichloroethene (DCE)
 tetrachloroethene (PCE)
 trichloroethene (TCE)
 vinyl chloride
 xylenes
3.1 Acetone
Acetone is a common household solvent which is miscible in water. Acetone can be found as the active
ingredient in nail polish remover and paint thinner. Acetone is also produced during the normal metabolic
process in the human body. In its pure form acetone is a flammable colorless liquid with a pungent or floral
odor.
Acetone was last detected above the Solid Waste Section Reporting Limit (SWSL) in in the downgradient
monitoring well MW-11S during the October 2008 water quality monitoring event. Acetone has been
periodically detected in samples from the C&D groundwater monitoring network at estimated concentrations
since October 2007. Acetone has been detected at higher concentrations above the SWSL in samples
from MW-6, MW-7, MW-8, MW-9, and MW-14 (i.e., wells installed upgradient of the C&D unit to monitor
groundwater between the MSW unit and the C&D unit). These data suggest that acetone impacts seen in
downgradient C&D monitoring wells are likely attributable to the MSW landfill.
3.2 Benzene
Benzene is classified as an aromatic hydrocarbon is a commonly used industrial chemical and a common
organic component of MSW and C&D landfill leachate and landfill gas. In its pure form, benzene can be
described as a colorless liquid with a petroleum-like odor. Under normal conditions benzene is only slightly
soluble in water. Benzene is considered a light non-aqueous phase liquid (LNAPL) since it has a specific

February 2017 7 0739615016.400

g:\projects\moore county\groundwater\2016 asd c&d landfill\final\a_report text\moore co asd for c&d landfill.docx
gravity less than water. Since benzene is less dense than water, benzene contamination can typically be
found at the top of the water column.
Benzene was detected in downgradient C&D monitoring wells MW-11S, MW-11D, MW-16S at
concentrations that exceeded the SWSL and the NC 2L Standard as recently as the April 2016 event.
Historically and during the April 2016 water quality monitoring event, benzene was detected in monitoring
wells MW-6, MW-7, MW-8, MW-9, and MW-14 (i.e., wells installed upgradient of the C&D unit to monitor
groundwater between the MSW unit and the C&D unit) at similar concentrations. Benzene was first
detected in monitoring wells located between the MSW and C&D landfills (MW-7, MW-8, and MW-9) during
the June 1995 event. Benzene was first detected in the downgradient C&D compliance monitoring wells
MW-11D and MW-12D during the March 2000 compliance monitoring event. These data suggest that
benzene impacts seen in downgradient C&D monitoring wells are likely attributable to the MSW landfill.
3.3 Chlorobenzene
Chlorobenzene is classified as an aromatic VOC and is a commonly used as an intermediate in the
manufacture of other chemical compounds including herbicides, dyestuffs, and rubber. Historically,
chlorobenzene was used in the production of certain pesticides including DDT. Chlorobenzene was also
used as the main precursor in the production of phenol. Under the right conditions chlorobenzene is also
an aerobic and anaerobic degradation by product of 1,4-dichlorobenzene and an aerobic degradation by
product of 1,2-dichlorobenzene. In its pure form chlorobenzene is a flammable colorless liquid with an
almond-like odor.
Chlorobenzene was detected in samples from the upgradient C&D monitoring well MW-14 at a
concentration that exceeded the SWSL as recently as the April 2014 water quality monitoring event.
Chlorobenzene has been detected at estimated concentrations below the SWSL in samples from MW-11S,
MW-11D, MW-13S, MW-13D, and MW-16S. Historically and during the April 2016 water quality monitoring
event, chlorobenzene was detected in the monitoring wells installed between the MSW and the C&D landfill
at similar concentrations. These data suggest that chlorobenzene impacts seen in downgradient C&D
monitoring wells are likely attributable to the MSW landfill.
3.4 Chloroethane
Chloroethane has had many industrial uses. Most notably chloroethane was historically used in the
production of tetraethyllead (TEL) which was used as an octane rating booster in gasoline from the early
1920s to the mid-1970s. TEL was phased out from use in the mid-1970s due to its damaging effect on
catalytic converters and due to the accumulative neurotoxicity of lead. After TEL was phased out of use
the demand for chloroethane dropped substantially. In its pure form chloroethane is a flammable colorless
liquid with a pungent odor.

g:\projects\moore county\groundwater\2016 asd c&d landfill\final\a_report text\moore co asd for c&d landfill.docx
Chloroethane was last detected in samples from MW-11S at a concentration that exceeded the SWSL
during the March 2000 water quality monitoring event. Chloroethane has been detected at estimated
concentrations below the SWSL in samples from MW-11S and MW-14. Historically, chloroethane was
detected in the monitoring wells installed between the MSW and the C&D landfill at similar concentrations.
These data suggest that chloroethane impacts seen in downgradient C&D monitoring wells are likely
attributable to the MSW landfill.
3.5 1,2-Dichlorobenzene
The constituent 1,2-dichlorobenzene was mainly used as an intermediate in the synthesis of agrochemicals
and as an insecticide for termites and locust. The volatile 1,2-dichlorobenzene in its pure form is a colorless
liquid that is poorly soluble in water.
The constituent 1,2-dichlorobenzene has been periodically detected at an estimated concentration below
the SWSL in samples from C&D monitoring wells MW-11S, MW-11D, MW-14, and MW-16S. Historically,
1,2-dichlorobenzene was detected in samples from the monitoring wells installed between the MSW and
the C&D landfill at similar concentrations. These data suggest that 1,2-dichlorobenzene impacts seen in
downgradient C&D monitoring wells are likely attributable to the MSW landfill.
3.6 1,4-Dichlorobenzene
The constituent 1,4-dichlorobenzene is classified as an aromatic VOC and was commonly used to control
moths (e.g., moth balls), molds, mildews, and as a disinfectant. 1,4-Dichlorobenzene is a colorless liquid
with a strong odor and under normal conditions has a low solubility in water.
The constituent 1,4-Dichlorobenzene was detected in downgradient C&D monitoring wells MW-11S,
MW-11D, MW-16S at concentrations that exceeded the SWSL, but below the NC 2L Standard as recently
as the April 2016 event. Historically and during the April 2016 water quality monitoring event, 1,4-
dichlorobenzene was detected in monitoring wells MW-6, MW-7, MW-8, MW-9, MW-14, and MW-15 (i.e.,
wells installed upgradient of the C&D unit to monitor groundwater between the MSW unit and the C&D unit)
at similar concentrations. 1,4-Dichlorobenzene was first detected in the downgradient C&D monitoring
wells MW-11D and MW-12D during the March 2000 compliance monitoring event; however, it was detected
in wells upgradient of the C&D landfill (MW-7, MW-8, and MW-9) as early as June 1995. These data
suggest that 1,4-dichlorobenzene impacts seen in downgradient C&D monitoring wells are likely attributable
to the MSW landfill.
3.7 1,1-Dichloroethane
The constituent 1,1-dichloroethane is a commonly manufactured chlorinated hydrocarbon which is used as
a feedstock in the chemical synthesis of 1,1,1-trichloroethane. It is also commonly used as a degreaser

February 2017 9 0739615016.400

g:\projects\moore county\groundwater\2016 asd c&d landfill\final\a_report text\moore co asd for c&d landfill.docx
and an insecticide. The constituent 1,1-dichloroethane in its pure form is a colorless oily liquid with a
chloroform-like odor.
The constituent 1,1-dichloroethane was last detected above the SWSL in samples from the downgradient
monitoring well MW-11D during the October 2008 water quality monitoring event. 1,1-Dichloroethane has
been detected periodically at estimated concentrations below the SWSL since October 2008 in samples
from MW-11S, MW-11D, MW-14, MW-16S, and MW-16D. Historically, 1,1-dichloroethane was detected in
samples from the monitoring wells installed between the MSW and the C&D landfill at similar
concentrations. These data suggest that 1,1-dichloroethane impacts seen in downgradient C&D monitoring
wells are likely attributable to the MSW landfill.
3.8 Cis-1,2-Dichloroethene
Constituent cis-1,2-dichlorothene is classified as an aliphatic VOC and is commonly produced as a
secondary contaminant via the biodegradation of tetrachloroethene. In its pure form cis-1,2-dichloroethene
is a flammable colorless liquid with a strong odor. Under normal conditions cis-1,2-dichloroethene has a
modest solubility in water.
Cis-1,2-dichloroethene was detected in downgradient C&D monitoring well MW-11D at a concentration that
exceeded the SWSL, but below the NC 2L Standard as recently as the April 2016 event. Historically and
during the April 2016 water quality monitoring event, cis-1,2-dichloroethene was detected in monitoring
wells upgradient of the C&D landfill (MW-6, MW-7, MW-8, MW-9, MW-14, and MW-15) at similar
concentrations. Cis-1,2-Dichloroethene was first detected in the upgradient (MW-6, MW-14, and MW-15)
and downgradient C&D monitoring wells (MW-11S, MW-11D, MW-16S, and MW-16D) during the April 2006
compliance monitoring event. These data suggest that cis-1,2-dichloroethene impacts seen in samples
from the downgradient C&D monitoring wells are likely attributable to the MSW landfill.
3.9 Tetrachloroethene
Tetrachloroethene or perchloroethene (PCE) is classified as an aliphatic VOC and was commonly used in
dry cleaning fluids and degreasers. In its pure form PCE is a nonflammable, highly volatile. Under normal
conditions PCE is slightly soluble in water. PCE is known as a dense non-aqueous phase liquid (DNAPL)
which means it has a specific gravity greater than that of water causing the substance to sink in water.
PCE was detected in downgradient C&D monitoring well MW-11D at a concentration that exceeded the
SWSL and the NC 2L Standard as recently as the October 2015 event. Historically, PCE has been detected
in monitoring wells upgradient of the C&D landfill (MW-6, MW-7, and MW-15) at similar concentrations.
PCE was first detected in the downgradient C&D monitoring wells MW-11D and MW-12D during the first
compliance monitoring event for the C&D landfill in October 1996. PCE was detected in wells upgradient

of the C&D landfill (MW-6 and MW-7) as early as the June 1995 event. These data suggest that PCE
impacts seen in downgradient C&D monitoring wells are likely attributable to the MSW landfill.
3.10 Trichloroethene
Trichloroethene (TCE) is classified as an aliphatic VOC and was commonly used as an industrial solvent.
In its pure form TCE is a nonflammable colorless liquid with a sweet odor. Under normal conditions TCE
is moderately soluble in water. TCE is also a daughter product of PCE biodegradation. TCE was detected
in downgradient C&D monitoring well MW-11D at a concentration that exceeded the SWSL, but below the
NC 2L Standard as recently as the October 2015 event. Historically, TCE has been detected in monitoring
wells upgradient of the C&D landfill (MW-6, MW-8, MW-14, and MW-15) at similar concentrations. TCE
was first detected in the downgradient C&D monitoring well MW-11D during the first compliance monitoring
event for the C&D landfill in October 1996. TCE was first detected in a monitoring well upgradient of the
C&D landfill (MW-6) during the June 1995 event. These data suggest that TCE impacts seen in
downgradient C&D monitoring wells are likely attributable to the MSW landfill.
3.11 Vinyl Chloride
Vinyl chloride is classified as an aliphatic VOC and is a daughter product of the biodegradation of PCE. In
its pure form vinyl chloride is a highly flammable gas with a sweet odor. Under normal conditions vinyl
chloride has a low solubility in water. Vinyl chloride is a common organic contaminant associated with MSW
and C&D landfills.
Vinyl chloride was detected in downgradient C&D monitoring wells MW-11S, MW-11D, and MW-16S at
concentrations that exceeded the SWSL and the NC 2L Standard as recently as the April 2016 event.
Historically and during the April 2016 water quality monitoring event, vinyl chloride was detected in
monitoring wells upgradient of the C&D landfill (MW-6, MW-7, MW-8, MW-9, MW-14, and MW-15) at similar
concentrations. Vinyl chloride was first detected in the downgradient C&D monitoring well MW-12S during
the October 1998 compliance monitoring event. Vinyl chloride was first detected in a monitoring wells
upgradient of the C&D landfill (MW-6, MW-7, MW-8, MW-9) during the June 1995 event. These data
suggest that vinyl chloride impacts seen in downgradient C&D monitoring wells are likely linked to the MSW
landfill.
3.12 Total Xylenes
Total xylenes refers to the total of three isomers (i.e., o-Xylene, m-Xylene, and p-Xylene). Each of these
isomers in its pure forms are flammable colorless liquids. Xylene is considered a BTEX aromatic
hydrocarbon. Xylenes are an important petrochemical produced during the manufacturing of coke fuel from
coal. Xylenes are primarily used as solvents in the printing, rubber, and leather industries or as a cleaning
agent for steel, silicon wafers, or integrated circuits.

Total xylenes have been detected periodically in the samples from the C&D groundwater monitoring
network since October 2007. Historically, total xylene was also detected in samples from the monitoring
wells installed between the MSW and the C&D landfill at similar concentrations. These data suggest that
total xylene impacts seen in samples from downgradient C&D monitoring wells are likely attributable to the
MSW landfill.

4.0 VOC SOURCE EVALUATION SENARIOS
Pursuant to 15A NCAC 13B .0544(b)(1)(l), the purpose of this ASD is to determine if a source other than
leachate from the C&D landfill’s waste disposal unit is responsible for the concentrations of COC’s that
have been reported in recent samples collected from the C&D landfill monitoring network. Based on the
review of the available data for the C&D landfill, Golder has identified the three most likely scenarios to
account for the COC concentrations in groundwater within the C&D landfill monitoring network.
4.1 Scenario 1 – Closed MSW Landfill Leachate
As discussed in detail in Section 2.0 of this report, the C&D landfill is located immediately downgradient of
the County’s closed MSW landfill. As noted in the previous section, the available historical data indicate
that the closed MSW landfill leachate is a known source of VOC groundwater impacts at the facility. The
total VOC plume at the facility has been closely monitored and evaluated since voluntary corrective action
began in 2005. To further evaluate the closed MSW landfill leachate as a potential source for low level
VOC impacts found in samples from the C&D monitoring well network, additional sampling activities were
performed in September 2016. These sampling activities included the collection of a MSW leachate sample
and additional groundwater samples for analysis.
4.2 Scenario 2 – Closed MSW Landfill Gas
As presented in Section 2.1, LFG migration from the MSW landfill unit has been an issue historically at the
facility. Five (5) LFG trench systems and three passive landfill gas extraction wells have been installed to
address this issue since 2005. The extent to which the MSW LFG has influenced groundwater at the facility
has been difficult to quantify and differentiate from leachate impacts. Groundwater impacts from LFG
migrating from the MSW facility is likely due to its close proximity. Therefore, LFG detections in C&D
monitoring wells may not necessarily be from the C&D landfill. Further, based on data provided in the ACM,
LFG may in part be responsible for the migration of the VOC plume over time. To further evaluate and
attempt to differentiate LFG impacts from leachate impacts, additional sampling and analysis was
performed in September 2016. The September 2016 additional sampling activities included the collection
of an LFG sample from a MSW passive gas extraction well.
4.3 Scenario 3 – C&D Landfill Leachate or Landfill Gas
In an attempt to differentiate the groundwater impacts of the closed MSW landfill, additional samples from
the C&D facility were collected for analysis in September 2016. These samples include: a C&D leachate
sample, additional groundwater, and soil-gas (headspace) samples were collected for analysis.

5.0 ASD INVESTIGATIVE ACTIVITIES
As discussed above, on September 7 – 8, 2016, Golder personnel collected additional groundwater,
headspace (air), and leachate samples from existing monitoring wells and gas vents at the Moore County
Landfill. These samples were used to better assess and differentiate the MSW and C&D landfill leachate,
and landfill gas as potential groundwater VOC sources.
5.1 Groundwater Sampling
The following monitoring wells were purged and sampled using low-flow sampling techniques via the use
of a peristaltic or portable bladder pump:
 MW-5 (the facility upgradient or background well)
 MW-11S (downgradient C&D compliance well)
 MW-11D (downgradient C&D compliance well)
 MW-14 (upgradient C&D compliance well)
 MW-16S (downgradient C&D compliance well)
 MW-16D (downgradient C&D compliance well)

Measurements of pH, specific conductivity, depth-to-water, dissolved oxygen (DO), oxidation-reduction
potential (ORP), temperature, and turbidity were recorded on approximately 3- to 5- minute intervals
during the purge (i.e., dependent upon the purge rate). In general, the purge rate was matched to the
yield of the monitoring well, as determined by continuously monitoring the depth-to-water and not
allowing the purge rate to exceed 500 milliliters per minute. Purging was continued until stabilization
was indicated by the field parameters. Prior to sampling, the laboratory-supplied sample containers
were 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 then collected directly from the pump discharge tubing into the labeled, laboratory supplied, pre-
preserved sample containers.
After collection, the samples were placed in a cooler on ice, under a chain-of-custody. Copies of the
sampling logs are presented in Appendix B. Included on each log is a description of the sampling
equipment, sampling location, sampling method, field observations, and water quality measurements.
The groundwater samples were sent via courier to Environmental Conservation Laboratories, Inc.
(ENCO) in Cary, NC to be analyzed for common cations (including calcium, magnesium, sodium, and
potassium) and anions (including carbonate, bicarbonate, chloride, nitrate, nitrite, sulfate, and sulfide).
In addition to these parameters, general chemistry parameters including ammonia, pH, alkalinity, and
total dissolved solids were also analyzed. The results of these analysis were then analyzed using basic
mixing calculations, piper plots, and stiff diagrams to assist in identifying the source of VOC impacts on

g:\projects\moore county\groundwater\2016 asd c&d landfill\final\a_report text\moore co asd for c&d landfill.docx
groundwater at the facility. The laboratory certificates-of-analysis, laboratory receipt condition forms,
and sample chains-of-custody are presented in Appendix C and the data is summarized on Table 6.
5.2 Soil-gas or Headspace Sampling
Soil-gas or headspace samples were collected from the following locations via the use of summa canisters
equipped with a flow regulator:
 GV-32 (MSW passive landfill gas vent)
 MW-11S (downgradient C&D compliance well)
 MW-11D (downgradient C&D compliance well)
 MW-14 (upgradient C&D compliance well)
 MW-16S (downgradient C&D compliance well)
 MW-16D (downgradient C&D compliance well)

To collect the soil-gas samples, tubing was inserted into the well to a depth of approximately 2 feet
above the groundwater level. With the exception of the deep groundwater wells, the groundwater level
in each monitoring well was below the top of the screen when the headspace sample was collected.
The summa canister regulator was calibrated by the lab prior to arrival at the site. Sampling was
commenced by first connecting the flow regulator (which was turned to the closed position) to the top
of the canister. Tubing was lowered in to the well or vent to the desired depth and then attached to the
flow regulator with a Swagelok fitting. The canister was then opened (with the flow regulator valve still
in the closed position) and the canister pressure was recorded. The flow regulator valve was then
opened and the canister was allowed to fill with the gas present in the well headspace. Each regulator
was calibrated to take a “30-minute” sample. After the 30-minute sampling period had elapsed the
regulator was closed and the canister pressure was recorded. After collection of the samples, the
summa canisters were shipped via courier to ENCO in Jacksonville, Florida for analysis of VOCs by
EPA method TO-15. The results of these analysis were then analyzed using Henry’s Law calculations
to determine if LFG partitioning to groundwater is occurring. The laboratory certificates-of-analysis,
laboratory receipt condition forms, and sample chains-of-custody are presented in Appendix C and are
summarized on Table 7.
5.3 Leachate Sampling
Two leachate grab samples were collected during the September 2016 ASD sampling event. A leachate
sample was collected at the MSW landfill from passive gas vent GV-31 (sample L-1). The sample was
collected using of a disposal bailer.
A leachate sample was collected from the C&D landfill from the eastern side of the C&D landfill where
historical seeps were noted (sample L-2). A hand auger was used to create a small hole in the landfill cap

g:\projects\moore county\groundwater\2016 asd c&d landfill\final\a_report text\moore co asd for c&d landfill.docx
until leachate was visible (approximately 2 ft. bgs). The leachate sample was collected by directly filling
the sample containers from leachate that collected in the small sump created with the hand auger. Field
parameters including pH, conductivity, temperature, and turbidity were obtained from each of these sample
locations. After completion of the leachate sampling the small sump dug in the landfill cap was repaired by
replacing and compacting the soil.
The leachate samples collected were sent to ENCO in Cary, NC to be analyzed for the same geochemical
cations, anions, and general chemistry parameters as the groundwater samples. In addition to these
parameters, the leachate samples were also analyzed for the NC Appendix I VOC parameter list to be used
for direct comparison to previous groundwater VOC concentrations recorded within the C&D groundwater
monitoring network. The laboratory certificates-of-analysis, laboratory receipt condition forms, and sample
chains-of-custody are presented in Appendix C and are summarized on Table 8.

6.0 ANALYTICAL RESULTS
The results from the laboratory analysis completed as part of this investigation are discussed in the following
sections. As presented in the previous section, the laboratory certificates-of-analysis, laboratory sample
receipt forms, and the sample chain-of-custody forms for groundwater, soil-gas (i.e., headspace), and
leachate samples analyzed during this investigation are presented in Appendix C. Analytical results for the
September 2016 ASD groundwater sampling, soil-gas (i.e., headspace) sampling, and leachate sampling
are summarized in Tables 6, 7, and 8, respectively.
6.1 Groundwater Sampling Results
Table 6, summarizes the groundwater cation, anion, and additional geochemical data collected and
analyzed during the September 2016 ASD sampling event. These results were used in the creation of piper
plots, stiff diagrams, and mixing simulations to be used for comparative purposes in an attempt to
differentiate leachate and LFG impacts on groundwater, as wells as impacts on groundwater from the
closed MSW landfill versus those from the active C&D landfill as alluded to in previous sections of this
report.
6.2 Soil-Gas Sampling Results
As presented, the soil-gas sampling results from the September 2016 ASD sampling event are summarized
in Table 7. Twenty-five (25) VOCs were detected at concentrations that exceeded the laboratory’s method
detection limit in the gas sample collected from MSW LFG vent GV-32. Of those, fifteen (15) VOCs were
detected at concentrations that exceeded the method quantification limit. Three (3) of the VOCs (toluene,
acetone, and 2-butanone) detected in the sample from GV-32 were reported in the sample from MW-14,
which is located between the MSW and C&D landfills, above the method detection limit. Fourteen (14) of
the VOCs (toluene; cyclohexane; n-hexane; heptane; cis-1,2-dichloroethene; 2,2,4-trimethylpentane;
2-hexanone; acetone; benzene; chloromethane; vinyl chloride; carbon disulfide; 1,1-dichloroethane; and
2-butanone) detected in the sample from GV-32 were reported above the method detection limit in one or
more samples from wells downgradient of the C&D landfill. Seven (7) organic constituents (i.e.,
1,2,4-trimethylbenzene; ethylbenzene; propene; PCE; TCE; 4-ethyltoluene; and total xylenes) were
detected in downgradient C&D monitoring wells that were not detected in GV-32.
6.3 Leachate Sampling Results
As presented in Table 8, six (6) NC Appendix I VOCs (benzene; 1,4-dichlorobenzene; ethylbenzene;
toluene; vinyl chloride; and total xylenes) were detected in the MSW landfill leachate sample L-1 (MSW)] at
concentrations exceeding the solid waste section limit (SWSL). Two of these constituents (benzene and
vinyl chloride) were detected a concentrations that exceed the NC 2L Standard. No NC Appendix I VOCs
were detected at concentrations exceeding the SWSL in the C&D leachate sample [L-2 (C&D)]. Leachate
cation, anion, and additional geochemical data are summarized in Table 8.

7.0 DATA EVALUATION
The following sections discuss the data evaluations and interpretations that were completed in
consideration of the three scenarios, proposed in Section 4.0, as sources of VOCs that have the potential
to impact groundwater quality at the at the C&D landfill.
7.1 Landfill Gas Source Evaluation
As presented, to evaluate LFG as a potential source of the VOC concentrations in groundwater samples
from the C&D monitoring network, Golder evaluated recent methane concentrations in groundwater
obtained from the April 2016 sampling event versus headspace concentrations of methane obtained on
August 5, 2016, Golder also evaluated the potential of landfill gas impacts using a numerical soil-gas to
groundwater partitioning model utilizing the soil-gas results from the September 2016 ASD sampling.
Although more qualitative, Golder also evaluated the potential for LFG to accumulate in the well casing,
allowing for direct exposure of groundwater within the well casing to be potentially impacted by headspace
gas. It is noted that impacted headspace is not necessarily required for LFG to impact groundwater, as
such impacts can happen outside of the well casing and upgradient of the well. These evaluations are
discussed in the following sections.
7.1.1 Methane Concentration Analysis
Dissolved methane was detected in ten (10) monitoring wells (MW-1, MW-2, MW-4, MW-6, MW-7, MW-9,
MW-11S, MW-14, MW-15, and MW-16S) during the April 2016 water quality monitoring event. Methane
was detected in the headspace of four (4) of the monitoring wells (i.e., MW-6, MW-7, MW-9, and MW-15)
during the April 2016 methane monitoring event. These data are summarized on Table 9. The presence
of methane in monitoring well headspaces and the presence of dissolved methane concentrations in
groundwater at the facility indicate that methane gas generated from the landfills may have a role in the
impacts seen in the groundwater. The limitation is that LFG generated from the MSW landfill cannot be
easily differentiated from LFG that may be generated from the C&D landfill.
Another potential indicator of LFG impacts on groundwater is pH, which can be helpful in discriminating
between LFG and leachate impacts. The pH pf leachate for older landfills tends to range from 7.5 to 9.0
standard units (Kjeldsen, et al., 2002); whereas LFG impacts tend to lower the pH of impacted groundwater
due to the dissolution of carbon dioxide, which is a major component of LFG, into the groundwater (Baker,
May 1998). In general, the pH of groundwater at the facility is higher around the solid waste units and
decrease with increased distance from the solid waste units. Historically, the pH of groundwater in
background well MW-5 has ranged from 3.0 to 5.0 standard units while the pH of groundwater in MW-6
through MW-9 (the wells located between the C&D and the MSW landfills) has ranged from approximately
5.0 to 8.0 standard units. These data suggest that groundwater impacts observed at the facility are
influenced more by leachate than landfill gas.

7.1.2 Henry’s Law Calculations (Groundwater to Soil-Gas)
Using the VOC concentrations obtained from the headspace samples collected during the September ASD
sampling event, Golder evaluated the COC concentrations observed in groundwater samples collected
during the April 2016 water quality monitoring event. Henry’s Law was utilized to calculate the theoretical
soil-gas concentrations that would be required to produce the concentration of the COCs in groundwater.
These theoretical values were then directly compared to the actual soil-gas concentrations observed during
the September 2016 ASD sampling event. The calculations were performed using the dimensionless form
of the Henry’s Law Constant (H) for the COCs. The following is an example of the calculation:
 Analytical Solution: H (dimensionless) = Concentration (gas)  Concentration (water)
or: Concentration (gas) = Concentration (water) x H (dimensionless)

 Where: H (dimensionless) = literature reference value obtained for each COC
Concentration (gas) = [units = parts per billion (ppb)]
Concentration (water) = [units = micrograms per liter (µg/L)]

 Observed April 2016 benzene concentration in groundwater (at MW-11D):

Benzene (water) = 1.3 µg/L

 Estimated gas concentration necessary to obtain observed groundwater concentrations:

COC (gas) = H x COC (water) µg/L

Benzene (gas) = 0.228 x 1.3 µg/L

Benzene (gas) = 0.2964 µg/L

 To express in ppb divide by mole conversion factor:

Benzene (gas) = 0.2964 ug/L  3.19E-03

Benzene (gas) = 157.24 ppbv

 Direct comparison:
Benzene (gas-calculated) = 92.9 ppbv
Benzene (gas-observed) = 2.1 ppbv

Table 10 presents the Henry’s Law calculations (as shown above) for each VOC detected in groundwater
from the C&D monitoring well network during the April 2016 water quality monitoring event.
As presented on Table 10, the numerical simulation suggests that the VOC concentrations in groundwater
samples should produce much higher soil-gas VOC concentrations than those that were analyzed from
their respective wells. Also, many VOCs detected in the groundwater samples were not detected in the

February 2017 19 0739615016.400

g:\projects\moore county\groundwater\2016 asd c&d landfill\final\a_report text\moore co asd for c&d landfill.docx
soil-gas samples. The direct comparisons between the theoretical (or calculated) headspace
concentrations and the soil-gas concentrations observed during the September 2016 ASD sampling are
presented on Table 10.

The assumptions used for this model are that steady state equilibrium conditions exist, that the groundwater
and soil-gas temperatures are steady and remains at 25°C, that the pressure in the vadose zone is steady
and remains at 1 atmosphere (atm) [or 101.325 kilopascals (kPa)], the groundwater volume and surface
area is fixed, and that there is no flux in the COC concentrations in the soil-gas or groundwater medium
that can be attributed to outside influences (e.g., barometric pressure fluctuations or changes in
groundwater flow velocity).
7.1.3 Henry’s Law Calculations (Soil-gas to Groundwater)
Using the same model assumptions, a similar analysis to the one presented above was conducted to
evaluate the dissolved phase concentrations of COCs that may be partitioned into the groundwater by the
gaseous phase COCs observed in the headspace sampling conducted during the September 2016 ASD
monitoring. The following equation represents this analytical solution:
 Analytical Solution: H (dimensionless) = Concentration (gas) ÷ Concentration (water)
or: Concentration (water) = H (dimensionless) x Concentration (gas)

The results of the soil-gas to groundwater calculations which are based on the equation above are
presented in Table 11. The results show that the gaseous phase VOCs detected in the soil-gas
samples collected from the C&D monitoring wells and the MSW gas vent are generally not present at
concentrations significant enough to partition dissolved phase VOCs at concentrations observed in
groundwater results obtained during the April 2016 water quality monitoring event. This finding could
be attributable to multiple factors including: no exposed screen in some of the monitoring wells due to
a high water table or, as suggested above, the impacts may not be derived by LFG. It should also be
noted that methane concentrations can vary greatly spatially and each methane should only be
interpreted as one single point in time. The September 2016 results coincide with the groundwater to
soil-gas calculations in the section above. The direct comparisons between the theoretical (or
calculated) groundwater concentrations and the groundwater concentrations observed during the April
2016 water quality monitoring event are presented on Table 11.
7.2 Leachate Source Evaluation
As presented two (2) leachate samples and six (6) groundwater samples were obtained during the
September 2016 ASD sampling event to assist in evaluating leachate as a potential source of COC
concentrations in groundwater present in the C&D landfill groundwater monitoring network. The September

February 2017 20 0739615016.400

g:\projects\moore county\groundwater\2016 asd c&d landfill\final\a_report text\moore co asd for c&d landfill.docx
2016 groundwater data and the available historical data for the facility were analyzed, via various methods,
to assess or simulate leachate impacts on groundwater within the C&D landfill groundwater monitoring
network. The results of these evaluations are discussed in detail in the subsequent sections.
7.2.1 Direct Comparison MSW vs C&D Leachate
The first method used to evaluate and differentiate MSW landfill leachate and C&D landfill leachate at the
facility was a direct comparison between the MSW leachate sample and the C&D landfill leachate sample
collected during the September 2016 ASD sampling event. The direct comparison between the two
leachate samples is presented in Table 8. In general, higher concentrations of general chemistry
parameters and total dissolved solids were observed in the MSW leachate sample collected from GV-32
[L-1 (MSW)] as compared to the C&D leachate sample [L-2 (C&D)]. As presented on Table 8, six (6) VOCs
(i.e., benzene, 1,4-dichlorobenzene, ethylbenzene, toluene, vinyl chloride, and total xylenes) were detected
in the MSW leachate sample. No VOCs were detected in the C&D leachate sample collected in September
2016. Based on these data, the MSW leachate is more likely to have impacted the water quality around
the C&D landfill, due to the number and concentrations of VOCs detected in the MSW leachate sample.
7.2.2 Piper Plot Analysis
After the direct comparison between leachate sample from the MSW and the C&D landfill, a piper plot
analysis was prepared to compare the geochemical facies of the leachates and the groundwater present at
the facility. The piper plot analysis allows for the direct comparison of the cation and anion data from the
leachate (presented on Table 8) and the groundwater samples (presented on Table 6) collected during the
September 2016 ASD sampling event. The samples from the MSW leachate, MW-11S, MW-11D, MW-16S,
and MW-16D fall within the mixed-bicarbonate geochemical facies. The sample from MW-14 plots within
the sodium-bicarbonate geochemical facies. Monitoring well MW-5 plots within the sodium-chloride
geochemical facies. The C&D leachate sample is significantly different from the other samples as it plots
within the calcium-sulfate geochemical facies.
As presented on Figure 4, the piper plot clearly shows some correlation between the cation and anion
composition of the MSW leachate sample and the C&D monitoring well samples. As shown, each impacted
C&D monitoring well composition plots in close proximity to the MSW leachate sample on the piper plot.
The background well MW-5 does not plot near the impacted wells, the MSW leachate, or the C&D leachate.
Likewise, the C&D leachate does not plot near any of the monitoring wells or the MSW leachate. The Piper
Plot data suggests that MSW leachate shares a similar geochemical signature with the impacted monitoring
well samples and that the MSW leachate is a likely source of the groundwater impacts.

7.2.3 Stiff Diagram Analysis
Fixed scale and variable (or sliding) scale stiff diagrams were prepared and are included as Figures 5
through 6. Initially, fixed and variable scale stiff diagrams were created to examine and compare the shape
signatures of each geochemical (i.e., cation and anion) sample collected during the September 2016 ASD
monitoring (Figure 5 and 6. The fixed scale stiff diagrams account for total dissolved solids (TDS) and
compare each sample based on a fixed scale (i.e., the same scale is used for each diagram). The variable
scale stiff diagrams ignore TDS and compare the signature of each sample (i.e., a unique scale is set for
each diagram).
The fixed and variable scale stiff diagrams on Figures 5 and 6 show that the samples from the impacted
wells (MW-11S, MW-11D, MW-14, MW-16S, and MW-16D) generally have a similar shape signature. The
shape signatures from the samples from the impacted wells are not similar to the background well (MW-5).
The variable scale Stiff diagrams on Figure 6 show there is a similarity between background monitoring
well MW-5 and the MSW leachate sample. The major difference between the MSW leachate and the MW-5
samples is the MSW leachate sample has a much higher concentration of TDS than MW-5. The C&D
leachate shape signature does not share similarities with groundwater samples or the MSW leachate
sample. Based on the shape signatures from Figures 5 and 6, no correlation between the Stiff diagrams of
the impacted groundwater sample and leachate samples can be made.
7.2.4 Mixing Analysis
In addition to analyzing the existing variations in aquifer geochemistry at the site, Golder modeled potential
leachate impacts to groundwater in affected downgradient wells at the facility using an analytical solution;
two models were run. The first model was based on simple mixing, where selected proportions of the C&D
leachate and background well MW-5 water were mixed (e.g., 10% leachate: 90% MW-5 water) to evaluate
the potential evolution of groundwater that was being impacted by increasing concentrations of leachate.
The simulated simple mixing model results are summarized in Table 12.
Figure 7 displays the simulated mixing model results on Stiff diagrams. These diagrams show the resultant
plot shapes of a solution represented by the geochemistry observed in the MW-5 sample progressively
mixed with increasing percentages of C&D leachate (1% leachate to 33% leachate). Comparing the results
of these shape signatures, the mixed results do morphologically trend toward a shape similar to the C&D
leachate; though, the shapes of the C&D leachate plots on Figure 7 do not resemble the shapes for the
impacted wells on Figure 6. Thus, these results indicate that typical C&D leachate is unlikely to be the
source of the VOCs that have been detected in the groundwater downgradient from the landfill.
The second model was based on simple mixing, where selected proportions of the MSW leachate and
background well MW-5 water were mixed (e.g., 10% leachate: 90% MW-5 water) to evaluate the potential

evolution of groundwater that was being impacted by increasing concentrations of leachate. The simulated
simple mixing model results are summarized in Table 13.
Figure 7 displays the simulated mixing model results on Stiff diagrams. These diagrams show the resultant
plot shapes of a solution represented by the geochemistry observed in the MW-5 sample progressively
mixed with increasing percentages of MSW leachate (1% leachate to 33% leachate). Comparing the results
of these shape signatures, the mixed results do not morphologically trend toward a shape similar to the
MSW leachate, and the shapes of the MSW leachate plots on Figure 7 do not resemble the shapes for the
impacted wells on Figure 6. Thus, these results indicate that the MSW leachate is unlikely to be the source
of the VOCs that have been detected in the groundwater downgradient from the landfill.
Based on these results, it is apparent that the geochemistry of impacted wells cannot be replicated by a
simulated leachate release using the facility’s upgradient groundwater chemistry as the sole solution and
C&D or MSW leachate chemistry, assuming that there is no precipitation of the ions of interest.
7.3 Groundwater Modeling
An analytical groundwater flow model was constructed using AquiferWin32 version 4.0 by Environmental
Simulations (2009) to simulate groundwater flow in the uppermost aquifer based on site and regional aquifer
conditions. The model was calibrated based on site groundwater levels and hydraulic gradients. The
primary assumptions included a median hydraulic conductivity of 12.84 feet per day based on site slug
tests, an aquifer storativity of 0.1, an aquifer top of 410 feet above mean sea level (AMSL), and an base of
338 feet AMSL. Recharge is applied at a rate of 0.00208 feet per day representative of summer conditions
and 0.00421 feet/day recharge for winter conditions from base flow separation curves for Drowning Creek
(USGS 2133500). The recharge was applied from the topographic high, east of the site, and the interpreted
downgradient limit of the water table aquifer, to Horse Creek, to the west of the facility. The western extent
of the aquifer is interpreted to be along Horse Creek where the aquifer thins. The groundwater flow is
interpreted to be controlled by topography and flows radially from the topographic high to the east of the
site and flow to the west towards Horse Creek and its tributaries, which are hydraulically connected to the
aquifer where groundwater discharges. A constant head elevation of 399 feet AMSL was imposed based
on measured groundwater elevations and interpreted groundwater on the eastern side of the closed
landfill. The groundwater gradient was developed from line sinks located along all the perennial and
intermittent stream sections identified from the Stream Identification Map, April 17, 2013, prepared by
Golder. Linear discharge sink head elevations set to interpreted stream bed elevation from site contour
maps. The model, presented as Figure 8 and Figure 9, simulated steady state conditions using solutions
developed by Strack (1989) for two dimensional flow in an unconfined aquifer.

The model was used to simulate steady state conditions during summer and winter. The model
groundwater elevations were compared to measured elevations at each observation well. The particle

tracking lines have 1 year markers and are shown on Figure 8 and Figure 9. Summary output files from
the AquiferWin 32 analytical flow model for each of the scenarios are provided in Appendix D. In general,
the groundwater model confirms that groundwater flow presented on Figure 3 is accurate. The particle
trace assessment shown on Figure 8 and Figure 9 also confirm that groundwater impacts observed in the
C&D groundwater monitoring network could potentially be from the MSW landfill. The flow arrows shown
on the figures show a median of approximately 6 to 7 years before groundwater impacts from the MSW
could be observed within the C&D monitoring network. The particle trace modelling does not take into
account concentrations of the contaminants or the degradation of volatile organics during the transport time
period so an estimation of concentrations cannot be made. However, because the MSW landfill has been
accepting waste since 1968 this scenario is supported based on the analytical model.
7.4 Historical Data Review and Evaluation
A historical data table is presented as Table 4. As presented, the oldest historical data currently available
for the landfill facility date back to June 1995 (i.e., before operation of the C&D landfill began). An
examination of this data displays several VOC detections in monitoring wells installed between the MSW
and C&D landfills (i.e., upgradient of the C&D landfill). The historical data suggest that a release of leachate
from the closed MSW landfill occurred prior the construction and operation of the C&D landfill. This fact
has been well documented throughout the life of the C&D landfill and was the reason the County voluntarily
entered corrective action at the MSW landfill.
After the installation of monitoring wells downgradient of the C&D landfill, VOCs were immediately detected
in groundwater samples. VOC detections in the C&D landfill date back to the initial sampling event on the
C&D monitoring network in October 1996. An examination of this data shows a declining trend in VOC
concentrations over time, which was the main reason MNA was chosen as the remedy for the site after
completion of the ACM in 2005. The presence of VOCs in samples from MSW monitoring wells pre-dating
the C&D landfill, as well as the presence of VOCs in groundwater during the initial monitoring event
preformed at the C&D landfill, indicate that groundwater impacts observed at the site are due to a release
from the MSW landfill.

8.0 CONCLUSIONS AND RECOMMENDATIONS
Based on the data and evaluations presented herein, it does not appear that the C&D leachate is the source
of VOCs observed in groundwater samples collected from the C&D network. Also, landfill gas does not
appear to significantly contribute to groundwater impacts observed at the site based on the data presented
herein. As presented in Section 7.3 of this report, VOC impacts at the site have been observed since June
1995 and pre-date the C&D landfill. A summary of the data and evaluations are provided below:
 Scenario #1 - Closed MSW Landfill Leachate: As presented, this appears to be the most
likely scenario due to VOC impacts in groundwater pre-dating the C&D landfill operation
facility or shortly after the commencement of operations, and the fact that the C&D wells
are directly downgradient of the MSW unit. Supporting evidence for this scenario are
summarized below:
 Higher pH values in impacted wells (as presented in Section 7.1.1)
 Presence of VOCs in MSW leachate but not in C&D leachate (as presented in Section
7.2.1)
 Stronger correlation in cation and anion composition between the MSW leachate
sample and the C&D monitoring well samples on the piper plot (as presented in Section
7.2.2)
 Pre-C&D waste historical groundwater data show groundwater VOC impacts
downgradient of the MSW landfill (as presented in Section 7.3)
 The groundwater model (presented in Section 7.2.5) and recent EPA Biochlor
modeling (present in the April 2016 Water Quality Monitoring Report) support this
scenario
There was no strong dissenting evidence to suggest that leachate from the MSW landfill
was not contributing to the groundwater impacts noted in recent groundwater samples at
the facility. In fact, this theory has been assumed as the source of the groundwater impacts
at the facility since the mid-1990s. The only potentially contrary evidence is summarized
below:
 Weak correlation between the variable scale Stiff diagrams from the MSW leachate
sample and groundwater samples obtained from the C&D monitoring well network (as
presented in Section 7.2.3)
 Mixing analysis was inconclusive (as presented in Section 7.2.4)
 Scenario #2 – Closed MSW Landfill Gas: As presented, there was some evidence to
suggest that landfill gas from the MSW landfill was contributing to groundwater impacts at
the facility. Supporting evidence for this scenario are summarized below:
 Dissolved methane is present in groundwater samples at the facility (as presented in
Section 7.1.1)
 Historical and continuous evidence of methane gas migration from the MSW landfill
(as presented in Section 2.1)
Opposing evidence of this theory is summarized below:
 Higher pH values in impacted wells (as presented in Section 7.1.1);
 No significant correlation between the headspace (i.e., soil-gas) samples collected and
the groundwater impacts observed at the facility when evaluated using Henry’s Law
(as presented in Section 7.1.2 and 7.1.3)

g:\projects\moore county\groundwater\2016 asd c&d landfill\final\a_report text\moore co asd for c&d landfill.docx
 Scenario #3 – Active C&D Landfill: As presented, this appears to be the least likely
scenario. Supporting evidence of the C&D landfill contributing to groundwater impacts is
summarized below:
 The observation of landfill gas in downgradient groundwater monitoring wells at the
C&D landfill during recent methane monitoring events.
Dissenting evidence of this theory is summarized below:
 No significant correlations between LFG and groundwater VOC concentrations noted
in the Henry’s Law calculations (as present in Section 7.1)
 No VOCs detected in the leachate sample obtained from the C&D landfill (as presented
in Section 7.2.1)
 No correlation in cation and anion composition between the C&D leachate sample and
the C&D monitoring well samples on the piper plot (as presented in Section 7.2.2)
 No correlation between the mixing simulations and the VOCs concentrations observed
in the C&D monitoring well network (as presented in Section 7.2.4)
 Pre-C&D waste historical groundwater VOC concentrations (as presented in Section
7.3)
 Conformance to the groundwater model (present in Section 7.2.5) and recent EPA
Biochlor modeling (present in the April 2016 Water Quality Monitoring Report) of the
MSW landfill groundwater impacts

The data collected during the September ASD sampling event summarized in this report, support that the
most likely cause of VOC groundwater impacts at the C&D facility is the closed MSW landfill. Presently,
there appears to be very little risk presented by the groundwater impacts as the VOC concentrations are
relatively low, the plume appears to be contained on site, no receptors have been identified immediately
downgradient, and the MSW landfill is already in corrective action. Based on these evaluations,
conclusions, and supporting statements, Golder recommends and the County is respectfully requesting,
that NC DEQ allow the County to continue with detection monitoring at the C&D landfill and corrective action
at the MSW landfill as prescribed in the ACM.

Notes:
1.) ft AMSL = feet above mean sea level
2.) -- = not measured or no data3.) TOC = top of casing
4.) DTW = Depth to Water
5.) NI = not installed
6.) MW = monitoring well7.) * = anamolous data
8.) TOC and water elevation data for dates prior to October 2007 from HDR Engineering, Inc. of the Carolinas Semi-Annual Monitoring Reports and the July 2006 Water Quality Monitoring Plan.
9.) MW-10 TOC elevation inferred from historical depth-to-groundwater and groundwater elevation measurements.
10.) Groundwater elevation and depth-to-water measurements appear to be anamolous for MW-14 during the 10/13/03 event and MW-15 during the 4/19/00 event and are not included in mean, maximum or minimum calculations.

applicable.

TM Laboratory blank is interference-free.

TM Surrogate recoveries are provided for each analytical method, where
applicable.

TM Surrogate recoveries for each method are within the acceptable limits (i.e., at
least 50% of the surrogates were within range).

TM MS/MSD/LCS data results are provided for each analytical method.

 The matric spike and matrix spike duplicate had recoveries that were outside
acceptance limits for propene, but by virtue of a laboratory control sample being
in control, the laboratory has demonstrated to be in control of its internal process.

TM MS/MSD/LCS recoveries for each method are within the acceptable limits (i.e.,
at least 1 of the 3 were within range).

Page 3 of 3

TM Proper EPA SW-846 analytical methods were used for analysis.

5.0 DATA REPORTING

TM All analytical reporting associated with the event was performed by the
contracted lab.

TM 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.

TM 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.

 GV-32 ALLX5.4
 MW-11S ALLX6.16 (n-Hexane X12.3)
 MW-11D ALLX6.32 (Acetone X 12.6, total light petroleum hydrocarbons X12.6)
 MW-14 ALLX5.48
 MW-16S ALLX6.28
 MW-16D ALLX1.59

TM The report provides the reporting limit for each constituent.

TM The results were reported at or below their proper reporting limits (i.e., GA
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.

N/A No inorganic or organic constituents were reported above their respective GA
MCLs in wells or field/equipment/trip blanks, or above Surface Water
Standards in surface points.

N/A No quantifiable inorganic or organic constituents were detected in a well or
surface water point at concentrations outside of their historical range (more
than 5X previous concentrations or first-time detections).
