RE: WATER QUALTITY MONITORING REPORT, 2ND SEMI-ANNUAL 2017 SAMPLING EVENT MOORE COUNTY LANDFILL, PERMIT NO. 63-01 MOORE COUNTY, NORTH CAROLINA
Dear Jackie: On behalf of Moore County, Golder Associates NC, Inc. (Golder) is submitting the enclosed Water Quality
Monitoring Report (Report), which documents the results of the December 12 – 14, 2017, compliance and
corrective action monitoring event at the Moore County Landfill located in Aberdeen, North Carolina. Surface water monitoring point SW-3 did not have flowing water during this event and no sample could be
collected.
Groundwater samples collected from detection monitoring wells (i.e., active C&D groundwater monitoring wells) during the December 2017 event were analyzed for North Carolina Appendix I volatile organic
compounds (VOCs) and Resource Conservation and Recovery Act (RCRA) metals. Groundwater samples collected from monitored natural attenuation (MNA) monitoring wells were analyzed for NC
Appendix I VOCs, RCRA metals, and an approved suite of MNA parameters. A private water supply well located north of the landfill at the Blake residence (an adjacent property) and three surface water samples
were sampled and analyzed for NC Appendix I VOCs and RCRA metals.
As presented, one inorganic constituent (arsenic) was detected at concentrations above the Solid Waste Section Limit (SWSL) and groundwater protection standard (NC 2L Standard) in the samples from one or
more downgradient monitoring wells during the December 2017 sampling event as it has been during previous sampling events. Based on statistical evaluation, the arsenic concentrations in MW-6, MW-7,
MW-9, MW-11S, MW-14 and MW-15 were below statistically determined facility background concentrations. Based on this evaluation in conjunction with the additional site-specific data presented in
the March 29, 2017, semi-annual monitoring report and alternate source demonstration for arsenic, the arsenic in groundwater at the site is interpreted to be naturally occurring and unrelated to landfill activities.
Five NC Appendix I VOCs were detected in samples from one or more downgradient monitoring wells at
concentrations above the SWSLs during this event: benzene; chlorobenzene; 1,4-dichlorobenzene; cis-1,2-dichloroethene; and vinyl chloride. Of these VOCs, the concentrations of benzene (MW-6, MW-7,
MW-8, MW-9, MW-11S, MW-11D, MW-14, and MW-15); and vinyl chloride (MW-6, MW-7, MW-11S, MW-11D, and MW-14) exceeded their respective NC 2L groundwater standards (NC 2L Standards). The
concentrations of vinyl chloride in samples from MW-8, MW-13S, MW-15, MW-16S, and MW-16D the concentration of tetrachloroethene in the sample from MW-11D were also above their respective NC 2L
Standards but were estimated below the SWSLs and no further action is required. In general, concentrations are consistent with historical data. No constituents were detected above SWSLs at
surface water monitoring locations during this event and surface water results are generally consistent with historical data.

1.0 INTRODUCTION
This report summarizes the monitoring results from the second semi-annual 2017 water quality monitoring
event at the Moore County Landfill conducted December 12 - 14, 2017. The Moore County Landfill is
comprised of two waste disposal areas: the closed Municipal Solid Waste (MSW) Landfill located on the
eastern side of the facility and the active Construction and Demolition (C&D) Landfill located on the
western side of the facility. The facility is maintained by the County under Permit No. 63-01 issued by the
NC Department of Environment Quality (DEQ, formerly the Department of Environment and Natural
Resources).
Due to groundwater impacts from volatile organic compounds (VOCs) at the closed MSW landfill, the
closed MSW facility entered into a voluntary corrective action program [i.e., Monitored Natural Attenuation
(MNA)] and monitored water quality in accordance with Title 15A of the North Carolina Administrative
Code (NCAC) 13B .0601 and in accordance with the facility’s approved modified Water Quality Monitoring
Plan (WQMP) following the submittal of an Assessment of Corrective Measures (ACM) in July 2005. In
accordance with a letter received from NC DEQ on September 28, 2017, Moore County submitted a
Landfill Gas Remediation Plan and a Groundwater Corrective Action Milestone Schedule which included
the completion and submittal of the NC Solid Waste .0500 Groundwater Corrective Action Application to
remedy impacts at the closed MSW landfill. The Landfill Gas Remediation Plan and Groundwater
Corrective Action Milestone Schedule were approved by NC DEQ on February 13, 2018.
In addition, a separate letter received from NC DEQ dated September 28, 2017 the solid waste section
requested that the active C&D landfill enter into assessment monitoring detailed in 15A NCAC 13B .0545.
In response to this letter an Assessment Monitoring Work Plan was submitted and approved by NC DEQ
on January 23, 2018.
1.1 Site Description and Background
The location of the facility is shown in the inlay on Drawing 1. The Moore County Landfill is located in the
southwestern part of the Moore County between the towns of Pinehurst and Aberdeen, North Carolina.
Access to the site is from State Highway 5, located east of the facility.
The facility is bound to the west by Horse Creek and to the north and south by unnamed tributaries of
Horse Creek. The location of these surface water features are shown on Drawing 1. A power-line right-
of-way transects the property and represents the eastern boundary of the closed MSW waste disposal
area.
As presented on Drawing 1, 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
March 2018 2 0739-615017.100

350 feet AMSL in the southwestern portion of the facility. The site is surrounded predominantly by
wooded, agricultural, or rural residential properties.
The Moore County Landfill comprises approximately 314 acres and contains a closed, unlined MSW unit,
an active C&D unit, and several closed Land Clearing & Inert Debris (LCID) units. In conjunction with
Moore County, Republic Services of NC, LLC operates a solid waste transfer station located on the
southwestern portion of the property. The MSW accepted waste from approximately 1968 to 1993 and
was closed prior to October 1993, with final closure approval in December 1996; the County expressed
their intent to comply with post-closure monitoring regulations in January 1997. The MSW area
encompasses approximately 60 acres, 12 of which have a clay cap. The County began transferring MSW
waste in 1993. The County temporarily stockpiled C&D waste from approximately 1993 to 1996, until the
current landfill was permitted and built (HDR, 2005).
1.2 Compliance Monitoring History
The first water quality monitoring event at the facility was conducted in June 1987 on five monitoring wells
(MW-1 through MW-5). These wells are downgradient of the current C&D facility. Wells MW-6 through
MW-9 were added in March 1995 to monitor the area between the MSW and C&D facilities.
Although the facility is currently monitored under title 15A NCAC 13B.600 Rules, groundwater corrective
action was initiated voluntarily due to concerns of off-site migration. Concerns of off-site migration were
first expressed by the NC DEQ in January 1996. A private water supply well at the Blake residence
(PW-1), located upgradient of the facility, was added to the monitoring network in 1996, along with
upstream and downstream surface water monitoring points (SW-2 and SW-1). Additional monitoring
wells were installed in September 1996 in an effort to delineate the contamination detected in the other
site wells, and to serve as monitoring points for the C&D facility. These wells include MW-11S/D,
MW-12S/D, MW-13S/D, and MW-14. Monitoring wells MW-16S/D were later installed to replace
MW-12S/D during an expansion of the C&D facility.
In December 1999 a work plan was submitted to NC DEQ by HDR Engineering Inc. of the Carolinas
(HDR) to address off-site migration concerns. The work plan was initiated in March 2000 and water
quality assessment activities commenced. A confining unit was identified at depth, which was reported to
limit vertical groundwater contamination. In January 2005, NC DEQ requested that Moore 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 if increasing trends in VOCs were observed in
groundwater. 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). In 2005, a trenching and venting network consisting of a trench and 12 passive
March 2018 3 0739-615017.100

LFG vents were installed to address LFG concerns; this network was expanded via 12 additional LFG
vents in 2007. Three in-waste passive gas vents (GV-30, GV-31, and GV-32) were installed in February
2014 as part of the Contingency Plan Update and Implementation Plan-Revised approved by NC DEQ on
June 5, 2013.
A revised Water Quality Monitoring Plan was prepared in July 2006 and approved October 13, 2006, by
NC DEQ. This Plan includes monitoring of NC Appendix I VOCs and 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, Moore County received permission to
eliminate hydrogen, carbon dioxide, and volatile fatty acids from the semi-annual monitoring list, and
complete groundwater modeling annually. This letter also specified that the County will 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 sampling event. The CAER was
submitted in May 2012 and NC DEQ granted the County permission to continue MNA for another five
year period at the end of which the County is required to submit another CAER (after the 2016 sampling
events). In order to better assess surface water quality and potential offsite plume migration at the site
two additional surface water points (SW-3 and SW-4) were added to the compliance monitoring network
upon approval of the CAER in May 2012.
In two letters dated September 28, 2017, the NC DEQ requested Moore County implement landfill gas
and groundwater corrective action at the closed MSW landfill and commence assessment monitoring at
the active C&D landfill. Since this communication the County has submitted a Landfill Gas Remediation
Plan, a Groundwater Corrective Action Milestone Schedule (including the submission of the NC Solid
Waste .0500 Groundwater Corrective Action Application), and an Assessment Monitoring Work Plan
which have been reviewed and approved by NC DEQ. In accordance with the Groundwater Corrective
Action Milestone Schedule, the County will continue MNA performance monitoring semi-annually and will
conduct MNA performance modeling annually (during the second semi-annual 2018 event) to evaluate
whether on-site conditions remain favorable for natural attenuation (i.e., no change from the previous
monitoring schedule). In addition the County will enter the assessment monitoring program at the active
C&D landfill during the first semiannual water quality monitoring event in 2018 as the March 29, 2017
Alternate Source Demonstration is being held for further review by NC DEQ pending receipt of additional
data.
1.3 Hydrogeologic Setting
The facility is located in the inner Coastal Plain Physiographic Province of North Carolina. The geologic
units of this region are relatively young, dating from the Cretaceous to the Tertiary period (NCGS, 1985).
March 2018 4 0739-615017.100

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 (see Figure 2) (NCGS, 1985 and Sohl, Norman, and James, 1991).
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). Groundwater occurs at
depths varying from approximately 5 to 38 feet below ground surface across the entire site.
Measurements of groundwater elevations obtained during the December 2017 monitoring event are
summarized in Table 1 and were used to prepare a groundwater surface contour map presented on
Drawing 1.
Surface water and groundwater at the site generally 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.
Based on the December 12, 2017, groundwater surface contour map, the hydraulic gradient in the
shallow aquifer underlying the site as measured along the conceptual flow path shown on the contour
map was calculated to be approximately 0.018 feet per foot. Groundwater velocities were calculated
using a hydraulic conductivity of 5.59E-3 centimeters per second (cm/s), which is the average of the
hydraulic conductivities calculated from slug tests from the facility. 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 groundwater surface contour map and interpreted flow directions are generally
consistent with previously submitted 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.
The average estimated linear groundwater flow velocity under the waste management units is
approximately 300 feet/year, which is consistent with previous estimates (Table 2). The range of
groundwater flow is expected to vary depending on topographic and hydrogeologic conditions. 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
March 2018 5 0739-615017.100

for heterogeneous and/or anisotropic conditions that may be present in the uppermost aquifer at the
facility.
2.0 FIELD PROGRAM, MONITORING RESULTS AND DISCUSSION
Field activities conducted for the December 2017 sampling event are discussed in the following sections.
2.1 Visual Inspection Program
In order detect a potential release at the earliest possible time; the visual inspection program is used at
the Moore County closed MSW and active C&D Landfills by the sampling personnel. This program
includes physical indicators such as potential water table mounding beneath the waste management unit,
physical examination of any stresses in biological communities, visible signs of leachate migration (i.e.,
leachate seeps), unexplained changes in soil characteristics, and any other change to the environment
due to the waste management unit. During the December 2017 compliance monitoring event, no physical
indicators of a potential release were observed in the vicinity of the waste management areas by the
sampling personnel.
2.2 Well Network and Groundwater Elevation Measurements
The current compliance network of groundwater monitoring wells at the facility consists of 5 detection
monitoring wells (MW-8, MW-11D, MW-13S, MW-13D, and MW-16D) and 12 MNA wells (MW-1, MW-2,
MW-3, MW-4, MW-5, MW-6, MW-7, MW-9, MW-11S, MW-14, MW-15, and MW-16S). Available
monitoring well construction information for all site monitoring wells is summarized on Table 3 and the
well locations are shown on Drawing 1. The well locations were selected to yield groundwater samples
representative of the conditions in the uppermost aquifer underlying the facility; to monitor for potential
releases from the landfill units; and to assess the progress of natural attenuation. As presented, two
upstream (SW-1 and SW-2) and two downstream (SW-3 and SW-4) surface water monitoring points, and
one private water well (PW-1) are also monitored in accordance with the approved monitoring plan.
Depth-to-water measurements are recorded to the nearest 0.01 foot prior to initiating groundwater purging
and sampling activities. The respective groundwater elevations for this event as well as historical
groundwater elevation data are presented in Table 1.
As presented, recent groundwater elevation data for the monitoring well network indicate that the
hydraulic head level in the uppermost aquifer beneath the facility is fairly consistent, with temporal
variation from the long-term average limited to approximately 3 - 12 feet (plus or minus). The range in
fluctuation appears to be greatest in the side-gradient background well MW-5. The range in fluctuation in
the downgradient compliance wells varies depending on their location, relative to the hydraulic discharge
boundary.
March 2018 6 0739-615017.100

2.3 December 2017 Groundwater and Surface Water Monitoring Event
Personnel from Golder visited the facility from December 12 – 14, 2017, to purge and sample the 17
groundwater monitoring wells; to sample the four surface water monitoring points; and to sample the
Blake residence private water well PW-1. Surface water monitoring point SW-3 did not have discernable
flow this event and therefore was not sampled.
The monitoring wells were purged and sampled using a portable peristaltic or bladder pump and micro-
purge procedures. During the micro-purging process measurements of temperature, pH, specific
conductivity, turbidity, dissolved oxygen, and oxidation reduction potential (ORP) were recorded on
approximately 2 to 5-minute intervals, depending on the purge rate. In general, the purge rate for each
well was matched to the yield of the monitoring well, as determined by continuously monitoring the depth
to the water, up to a maximum purge rate of 300 milliliters per minute. Purging was continued until
stabilization of the water quality parameters. MW-7 was purged dry and sampled the following day as it
did not yield sufficient water to satisfy low flow requirements.
Prior to sampling, the laboratory-supplied sample containers were prepared. Each sample container was
labeled with the sample identification number, sampling personnel, date and time of sample collection,
project name and number, and requested chemical analyses. MNA wells were also analyzed for ferrous
iron in the field.
The required groundwater samples were collected directly from the portable pump discharge lines in the
labeled, laboratory-supplied, pre-preserved sample containers after purging was completed based on
stabilization of all water quality parameters. After collection, the samples were placed in a cooler on ice,
under chain-of-custody control. Copies of the sampling logs are presented in Appendix A. Included in
each log is a description of the sampling equipment, method, location, field observations, and water
quality measurements.
The surface water samples were collected directly from the stream, by lowering the sample container into
the stream flow with the bottle opening facing downstream, the bottles were filled carefully to prevent
overflow and to minimize turbidity. Measurements of pH, specific conductivity, temperature, turbidity,
dissolved oxygen, and oxygen reduction potential were measured directly from the stream and recorded
during the collection of the surface water samples. After collection, the samples were placed in a cooler
on ice, under chain-of-custody control. Copies of the sampling logs are presented in Appendix A.
Included in each log is a description of the sampling equipment, method, location, field observations, and
water quality measurements.
The sample collected from the Blake residence private water well (PW-1) was collected from an outside
spigot at the well house, by allowing the water to purge for approximately 5 minutes before the bottles
were filled. Measurements of pH, specific conductivity, temperature, and turbidity were measured directly
March 2018 7 0739-615017.100

from the spigot flow and recorded during the collection of the sample. After collection, the samples were
placed in a cooler on ice, under chain-of-custody control. A copy of the sampling log is presented in
Appendix A. Included in the log is a description of the sampling equipment, method, location, field
observations, and water quality measurements.
2.4 Laboratory Analysis Program
The December 2017 groundwater and surface water samples were submitted to Environmental
Conservation Laboratories, Inc. (ENCO) of Cary, North Carolina under chain-of-custody control for
analysis. As presented, groundwater and surface water samples at the facility, including private well
PW-1, were analyzed for NC Appendix I VOCs and RCRA metals. Twelve monitoring wells (MW-1,
MW-2, MW-3, MW-4, MW-5, MW-6, MW-7, MW-9, MW-11S, MW-14, MW-15, and MW-16S) were also
analyzed for a selected group of MNA parameters. Three surface water monitoring points (SW-1, SW-2,
and SW-4) were collected during the December 2017 compliance monitoring event and were analyzed for
NC Appendix I constituents. The samples were received at the laboratory in good condition and properly
preserved.
2.5 December 2017 Compliance Sampling Results
Analytical results for NC Appendix I VOCs and RCRA metals for the December 2017 groundwater and
surface water samples are summarized in Tables 4 and 6 along with available historical data. A summary
of groundwater field parameters is included in Table 5 and a summary of surface water field parameters
in included in Table 7. The laboratory certificates-of-analysis, chain-of-custody forms, and laboratory data
reviews for the sampling event are included in Appendix B.
As presented, arsenic and barium were detected above their respective Solid Waste Section Reporting
Limits (SWSLs) in the samples from one or more downgradient monitoring wells during the December
2017 monitoring event. Five NC Appendix I VOCs were detected in samples from one or more
downgradient monitoring wells at concentrations above the SWSLs during this event: benzene;
chlorobenzene; 1,4-dichlorobenzene; cis-1,2-dichloroethene; and vinyl chloride. In general,
concentrations are consistent with historical data. A summary of total VOCs detected in samples from
each monitoring well during the December 2017 water quality monitoring event is presented in Table 8.
As presented in Table 6, no NC Appendix I organic or inorganic constituents were detected above the
SWSLs in the surface water monitoring points during this event.
3.0 LABORATORY AND FIELD QA/QC
A field blank was collected by Golder personnel as part of the December 2017 groundwater and surface
water sampling event. In addition to the field blank, a laboratory-prepared trip blank accompanied the
volatile sample containers for the December 2017 sampling event to and from the laboratory. ENCO
March 2018 8 0739-615017.100

analyzed the field blank for Appendix I VOCs and RCRA metals and the trip blank for Appendix I VOCs.
Reviews of the laboratory data were performed by Golder personnel and are included in Appendix B).
Based on Golder’s data review, silver was detected in one or more of the method blanks during the
December 2017 sampling event at estimated concentrations and the following concentrations are
considered blank-qualified for silver: MW-8, MW-11S, and MW-13S.
4.0 DATA EVALUATION
The results of the data evaluations are presented in the following sections.
4.1 North Carolina Groundwater and Surface Water Quality Standard
Comparisons
As presented in Table 4, the concentrations of arsenic in samples from six downgradient monitoring wells
were above the SWSL and the NC 2L Water Quality Standard (NC 2L Standard) during the December
2017 sampling event (MW-6, MW-7, MW-9, MW-11S, MW-14, and MW-15). One inorganic constituent
(lead) was detected above the SWSL and the NC 2L Standard during this event at PW-1. Lead has
historically been detected in samples from this well at concentrations above the groundwater protection
standard, and is likely due to the degradation of the well casing or piping. Further, lead has not been
recently detected at concentrations above the SWSL in landfill compliance wells.
The concentrations of the following VOCs were above their respective SWSL and NC 2L groundwater
standard during this event: benzene (MW-6, MW-7, MW-8, MW-9, MW-11S, MW-11D, MW-14, and
MW-15); and vinyl chloride (MW-6, MW-7, MW-11S, MW-11D, and MW-14). The concentrations of vinyl
chloride in samples from MW-8, MW-13S, MW-15, MW-16S and MW-16D and the concentration of
tetrachloroethene in the sample from MW-11D were also above their respective NC 2L Standards but
were estimated below the SWSLs and no further action is required. In general, concentrations are
consistent with historical data. There were no detections of NC Appendix I VOCs in the surface water
samples above SWSLs or applicable standards during the December 2017 sampling event.
4.2 Statistical Evaluations
As presented, arsenic was detected above its respective SWSL and NC 2L Standard in the samples from
downgradient monitoring wells MW-6, MW-7, MW-9, MW-11S, MW-14 and MW-15 during the December
2017 water quality monitoring event. The arsenic concentrations were statistically evaluated to determine
if the reported concentrations exceeded the facility background concentration and to evaluate if the
source of the arsenic is naturally occurring. The summary of statistical analysis and statistical worksheets
are presented as Appendix C.
Based on statistical evaluations, the arsenic concentrations at these locations did not represent
statistically significant increases (SSIs) over the facility background concentrations. These results are
March 2018 9 0739-615017.100

further supported by the other site-specific soil data presented in the Second Semi-Annual 2016 Water
Quality Monitoring Report which included an alternate source demonstration for arsenic, which indicated
that arsenic in groundwater at the site is naturally occurring and unrelated to landfill activities.
4.3 Monitored Natural Attenuation Evaluation
A series of monitoring wells within the constituent-of-concern VOC plumes shown on Drawing 2 were
selected for a performance evaluation of MNA processes. Monitoring wells MW-4, MW-6, MW-11S, and
MW-15 were selected since they form a relatively straight line, are situated approximately parallel to
groundwater flow (Drawing 1), and correlate with the study performed by HDR in the Water Quality
Monitoring Plan (2006). The December 2017 analytical data for these wells were evaluated using the
Environmental Protection Agency (EPA)’s natural attenuation screening protocol (1999).
Based on the EPA’s screening protocol, monitoring wells MW-6, MW-11S, MW-15 received scores
greater than 20, which indicates strong evidence for anaerobic biodegradation of chlorinated organics
(EPA, 1999). Monitoring well MW-4 received a score of 8, which indicates there is limited evidence for
anaerobic biodegradation of chlorinated organics. The MNA evaluation worksheets and natural
attenuation screening protocol forms are included in Appendix E.
Based on the results of the screening protocol, there is evidence that natural attenuation is occurring at
the site; therefore, modeling was performed on the December 2017 data to simulate remediation by
natural attenuation using a screening model called BIOCHLOR (EPA, 2000). Monitoring wells MW-4,
MW-6, MW-11S, and MW-15 were used in the model. Modeling parameters for advection, dispersion,
and modeled area were the same as previous models performed for the site, so that model results could
be compared. A 49-year simulation period was selected for the model, representing the time at which
waste was first placed in the landfill (the original source). The December 2017 results represent current
conditions at the facility and therefore, the model was calibrated to the current sample results by adjusting
the biotransformation data within a prescribed range specified by literature values within the BIOCHLOR
program. Once the model was calibrated a forecasted model was created by changing the simulation
period to 100 years to assess the size of the contaminant plume in the future. BIOCHLOR generates
plots that compare concentrations of tetrachloroethene (PCE), trichloroethene (TCE), dichloroethene
(DCE), and vinyl chloride (VC) over time with no degradation to concentrations where sequential 1st order
decay is occurring. The plots are provided in Appendix E. The centerline plots can be used to forecast
the contaminant plume size over time.
Because PCE and TCE were not detected in samples from downgradient monitoring wells MW-4, MW-6,
MW-11S, and MW-15 during the December 2017 monitoring event, the BIOCHLOR model could not be
calibrated; however, the absence of PCE and TCE in these downgradient samples could be considered
evidence of biodegradation. The concentration of DCE in the samples from MW-4, MW-6, MW-11S, and
MW-15 plots on or below the 1st order sequential decay curve. In both samples, the cis-1,2-DCE variety
March 2018 10 0739-615017.100

was the prominent form of DCE indicating that the detections represent daughter products of TCE. The
centerline plot for VC shows concentrations in samples from MW-6, MW-11S, and MW-15 plot below the
1st order sequential decay curve. The results from these plots indicate that natural attenuation is
occurring at the site and that as long as conditions at the site continue to be strongly anaerobic,
biodegradation will likely continue. According to the current data, it is the plume size has stabilized, as
indicated by the BIOCHLOR model. There is evidence that more aerobic conditions exist in the
monitoring well furthest from the contaminant plume (MW-4). These more aerobic conditions in the
furthest downgradient well will not likely impact the MNA at the site as VC and possibly DCE can both
degrade co-metabolically and can be directly oxidized to carbon dioxide under aerobic conditions (EPA,
2000).
5.0 CONCLUSIONS
As presented and based on the results summarized herein, Moore County Landfill will monitor the
uppermost aquifer beneath this facility in accordance with Groundwater Corrective Action Milestone
Schedule approved by NC DEQ on February 13, 2018 at the MSW landfill and the Assessment
Monitoring Work Plan approved by NC DEQ on January 23, 2018 at the C&D landfill.
