1.0 INTRODUCTION
This report summarizes the monitoring results from the March 29, 2017, groundwater and surface water
sampling event, and the April 3, 2017, leachate sampling event at the active South Wake Municipal Solid
Waste (MSW) Landfill in Wake County, North Carolina. Water quality monitoring is performed in
accordance with Title 15A of the North Carolina Administrative Code (NCAC) Subchapter 13B.1633. The
facility is owned by Wake County and operated by Wake County Disposal, LLC, a subsidiary of Waste
Industries USA, Inc., under Permit No. 92-22 issued by the North Carolina (NC) Department of
Environmental Quality (DEQ), formerly known as the Department of Environment and Natural Resources
(DENR).
1.1 Site Description and Background
The location of the facility is shown on the inlay on Drawing 1. The South Wake MSW Landfill is located
approximately 4 miles south of Apex, NC in Wake County. Access to the site is from NC Highway 55
Bypass, east of the site.
The Little Branch Creek is located along the southern property boundary and flows to the west, eventually
into the Shearon Harris Reservoir. The location of this surface water feature is shown on Drawing 1 and
Drawing 2.
Based on the topography as shown on Drawing 1, topographic surface elevations at the facility range
from approximately 260 feet above mean sea level (AMSL) along the drainages south and northwest of
the facility, to nearly 375 feet AMSL in the northeastern portion of the future footprint. The site is
surrounded predominantly by undeveloped, wooded properties, other landfills, and rural residential
properties.
The closed Feltonsville MSW Landfill, Permit 92-03, is located west of the active South Wake facility and
is maintained by Wake County. The active Highway 55 C&D Landfill, Permit 92-30, is operated by Griffin
Brothers Companies and is located north of the facility.
1.2 Compliance Monitoring History
Between September and November 2007, thirteen monitoring wells (MW-1, MW-1A, MW-2, MW-2A,
MW-3, MW-3A, MW-4, MW-5, MW-6, MW-6A, MW-7, MW-8 and MW-8A) were installed at the South
Wake facility to monitor groundwater quality beneath the facility. Background groundwater and surface
water monitoring at the facility was initiated in December 2007. Prior to the September 2013 event, the
facility’s Water Quality Monitoring Plan (WQMP) was revised to remove six existing monitoring wells from
the compliance monitoring network (MW-1A, MW-2A, MW-3A, MW-6, MW-6A, and MW-8A). Wells MW-6
and MW-6A were decommissioned and MW-1A, MW-2A, MW-3A, and MW-8A are monitored for water
levels only. As part of the revised WQMP, one of the Phase 2 expansion wells (MW-9) was also added to
the network; two additional future monitoring wells will be installed after excavation of the Phase 2 area.

May 2017 2 073-9603917

The facility’s revised monitoring network consists of one upgradient well (MW-1) and seven downgradient
wells (MW-2, MW-3, MW-4, MW-5, MW-7, MW-8, and MW-9) which monitor the uppermost aquifer
beneath the facility.
The facility’s monitoring network also includes five surface water sampling points: SW-1, SW-2, SW-3,
SW-4, and SW-5. The facility’s upstream sampling points consist of SW-1, SW-2, and SW-4. Surface
water sampling point SW-1 is located along a tributary to Little Branch north of the facility. Upstream
monitoring point SW-2 is located along another unnamed tributary to Little Branch northeast of the facility.
The third upstream point, SW-4, is located east of the facility along another unnamed tributary to Little
Branch. Surface water point SW-3 is located downstream and west of the MSW disposal area along an
unnamed tributary to Little Branch. Surface water point SW-5 is a second downstream sampling location
located west of the facility in Little Branch. Surface points are sampled in conjunction with the
groundwater monitoring wells in accordance with the facility’s permit and WQMP. Surface water
monitoring points SW-1, SW-2, and SW-3 are shared with the adjacent unlined, closed Feltonsville MSW
Landfill.
1.3 Hydrogeological Setting
Geologically, the facility is located within the Deep River basin and Durham sub-basin, which are Triassic
basins in the Piedmont Physiographic Province of North Carolina (NCGS, 1985). Generally, the Triassic
basin consists of Lower Mesozoic sedimentary and igneous rocks that filled rift basins. The Durham sub-
basin contains conglomerates, fanglomerates, sandstones, and mudstones. More specifically, all three
Deep River sub-basins contain a middle clay-shale and mudstone interval approximately 50 to 400
meters thick, which is evident by the red clay present at the site, in addition to the presence of
conglomerates and sandstones. The Deep River basin is bounded on the east by the Jonesboro fault
system and is intruded by intersecting north- and northwest-striking diabase dikes (Olsen, et al. 1991).
A diabase dike was identified within the facility boundaries during a magnetic survey performed during the
initial site investigation. The dike is steeply dipping and trends approximately N 45˚ E. The dike
bifurcates toward the southeastern portion of the facility property boundary. The dike does not intersect
the Phase I disposal area (CDM, 1998).
The uppermost groundwater beneath the facility is present in a shallow, unconfined aquifer comprised of
regolith, partially weathered rock, and conglomerate bedrock. Groundwater occurs at depths varying
widely from approximately 3 feet below grade to more than 35 feet below grade across the site.
Surface water and groundwater at the site generally flows to the south and west toward Little Branch
located along the southern property boundary. The Little Branch flows south to southwest and drains into
Big Branch, which drains into White Oak Creek. This creek then flows into the Shearon Harris Reservoir,
located approximately eight miles southwest of the facility.

May 2017 3 073-9603917

Based on the March 29, 2017, groundwater surface contour map, the average 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 0.032 feet/foot. Groundwater velocities were calculated using a hydraulic
conductivity of 3.77E-6 centimeters per second, which is the geometric mean of the hydraulic
conductivities calculated for the monitoring wells at the facility (Golder, December 2007). The estimated
effective porosity of the shallow aquifer is based on the most conservative value for the available effective
porosities of the hydrogeologic units, which is 0.22 (Golder, 2007).
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 per year), K = hydraulic conductivity (feet per year), i =
horizontal hydraulic gradient, and ne = effective porosity.
The average estimated linear groundwater flow velocity under the waste management unit is
approximately 0.56 feet/year toward the southwest or northwest (Table 2). 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.
2.0 FIELD PROGRAM, MONITORING RESULTS, AND DISCUSSION
Field activities conducted as part of the March 2017 sampling event are discussed in the following
sections.
2.1 Visual Inspection Program
In order to ensure that a potential release is detected at the earliest possible time, the visual inspection
program is used at the South Wake MSW Landfill by the sampling crew. 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 March 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 network of groundwater monitoring wells at the facility consists of eight wells. Available
monitoring well construction information for all site monitoring wells is summarized in Table 3, and the
well locations are shown on Drawing 1. The well locations were selected to yield groundwater samples

May 2017 4 073-9603917

representative of the conditions in the uppermost aquifer underlying the facility, and to monitor for
potential releases from the landfill unit. Three upstream surface water monitoring points (SW-1, SW-2,
and SW-4) and two downstream surface water monitoring points (SW-3 and SW-5) are also monitored.
Surface water monitoring points SW-1, SW-2, and SW-3 are shared with the adjacent unlined, closed
Feltonsville MSW Landfill.
Depth-to-water measurements are recorded to the nearest 0.01 foot prior to initiating groundwater purging
and sampling activities. The respective groundwater level elevations for this event are presented in
Table 1. The historical water level data are also shown on this table.
As presented, recent groundwater elevation data for the monitoring well network indicates that the
hydraulic head level in the uppermost aquifer beneath the facility is fairly consistent, with temporal
variation with the long-term average limited to approximately 10 feet (plus or minus) under normal
conditions. The range in fluctuation in the uppermost aquifer appears to be greatest in upgradient
background well MW-1, which is located in a groundwater recharge area, and downgradient wells MW-2
and MW-8A, which have shown large fluctuations between events. Overall, the range in fluctuation in the
downgradient compliance wells, which are located near groundwater discharge areas, is less, presumably
due to the stabilizing effect of the hydraulic discharge boundary.
2.3 March 2017 Groundwater Monitoring Event
Golder personnel visited the facility on March 29, 2017, to purge and sample monitoring wells MW-1,
MW-2, MW-3, MW-4, MW-5, MW-7, MW-8, and MW-9, and to sample surface water monitoring points
SW-1, SW-2, SW-3, SW-4, and SW-5. The facility’s leachate was sampled on April 3, 2017, by
Environmental Conservation Laboratories (ENCO).
Depth-to-water measurements were obtained from the network monitoring wells to the nearest 0.01 foot
using an electronic water level indicator prior to purging the wells. The respective groundwater level
elevations for this event are presented in Table 1 along with the historical water level data.
The monitoring wells were purged using dedicated bladder pumps. Measurements of pH, specific
conductivity, temperature, turbidity, dissolved oxygen, and oxidation reduction potential were recorded on
approximately 3- 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 groundwater, up to a maximum purge rate of approximately 250 milliliters per minute. Purging was
continued until stabilization was indicated by the water quality parameters.
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.

May 2017 5 073-9603917

The groundwater samples were collected directly from the dedicated bladder 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, sampling method, field observations, well location,
and water quality measurements.
The surface water samples were either collected directly from the stream, by lowering the sample
containers into the stream flow with the opening facing into the current flow or by using a decontaminated
stainless steel dipper, taking care to prevent the overflow of the sample containers and to minimize
sample-induced 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.
The leachate sample was collected by ENCO personnel on April 3, 2017, directly from the influent
leachate piping manifold that serves the leachate holding tank. After collection, the surface water and
leachate samples were placed in their respective coolers on ice, under chain-of-custody control. Copies
of the sampling logs are presented in Appendix A. Included in each log is a description of the sampling
equipment, sampling location, sampling method, field observations, and water quality measurements.
2.4 Laboratory Analysis Program
The March 2017 groundwater, surface water, and leachate samples were submitted to ENCO of Cary, NC
under chain-of-custody control for analysis. As presented, groundwater and surface water samples at the
facility were analyzed for NC Appendix I constituents. The leachate samples were analyzed for the DEQ
approved list of constituents for Subtitle D facilities. The groundwater and surface water samples were
received at the laboratory in good condition on March 30, 2017, and properly preserved. The leachate
sample was collected and transported to the laboratory in good condition on April 3, 2017, and properly
preserved.
2.5 March 2017 Sampling Results
Analytical results and field parameters for the March 2017 groundwater, surface water, and leachate
samples are summarized in Tables 4 through 8 along with available historical data. The laboratory
certificates-of-analysis, chain-of-custody form, and laboratory data reviews for the sampling event are
included in Appendix B.
As presented in Table 4, two NC Appendix I inorganic constituents (barium and zinc) were detected
above the Solid Waste Section Limits (SWSLs) in samples from one or more downgradient monitoring
wells during the March 2017 monitoring event. Barium and nickel were also detected at concentrations

May 2017 6 073-9603917

above the SWSLs in the upgradient well. No NC Appendix I organic constituents were detected above
the SWSLs in samples from downgradient monitoring wells during the event.
No Appendix I constituents were detected above their respective SWSLs in samples from surface water
monitoring locations during the March 2017 event. Also, leachate results were generally consistent with
available historical data for this facility.
3.0 LABORATORY AND FIELD QA/QC
A field blank was collected by Golder personnel as part of the March 2017 groundwater and surface water
sampling event. In addition to the field blank, a laboratory-prepared trip blank accompanied the volatile
sample containers to and from the laboratory. ENCO analyzed the field blank for NC Appendix I
constituents and the trip blank for NC Appendix I volatile organic compounds. Reviews of the laboratory
data were performed by Golder personnel and are included in Appendix B. During the March 2017 event,
copper and thallium were detected in the field blank and cadmium, chromium, nickel, and selenium were
detected in the lab blank, all at estimated concentrations. Based on Golder’s laboratory data review, the
following concentrations are considered blank-qualified: cadmium at MW-2, -3, -5, and SW-5, copper at
MW-7 and SW-2, chromium at MW-1, -2, -4, -5, -7, -8, -9, SW-2 and SW-4, nickel at
MW-2, -3, -4, -5, -7, -8, -9, and SW-1, -2, and -5, selenium at SW-1, and thallium at
MW-2, -3, -4, -5, -7,-8, -9, and SW-1, -2, -3, -4, and -5.
A laboratory method blank was also analyzed in conjunction with the April 3, 2017, leachate sample and
based off Golder’s laboratory data review there were no blank qualified concentrations.
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, one constituent was detected above its respective SWSL and groundwater
standard during this event: barium in the sample from upgradient well MW-1. No further action is
warranted for the background well as barium appears to be naturally occurring. Vanadium was detected
at estimated concentrations below the SWSLs but above the Solid Waste Section (SWS) Groundwater
Protection Standard (GPS) in the samples from MW-3, MW-4, MW-7 and MW-8 during this event. No
further action is warranted because concentrations are estimated below the SWSLs.

No NC Appendix I organic constituents were detected above the SWSLs and groundwater standards
during the March 2017 event. There were no detections of NC Appendix I constituents detected above
the SWSLs or surface water standards during this event.

1) Results in parentheses () are from re-analysis
2) Monitoring wells MW-6 and MW-6A were abandoned prior to the September 2013 event.
3) Monitoring wells MW-1A, MW-2A, MW-3A, and MW-8A have been removed from the monitoring network per the revised 2012 WQMP in September 2013 and are used for water levels only.
4) MW-9 was constructed in February 2012 and added to the monitoring network prior to the September 2013 event. The September 2013 - April 2014 events for MW-9 are background events.
5) Antimony was diluted for MW-1 by 2X and Barium was diluted for MW-1 by 5X for the March 2017 event.
