1.0 INTRODUCTION
This report summarizes the monitoring results from the September 28 -29, 2017, groundwater and
surface water sampling event, and the October 2, 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 added to the
November 2017 2 073-9603917

network; two additional future monitoring wells will be installed after excavation of the Phase 2 area. 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
November 2017 3 073-9603917

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.
Based on the September 28, 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 0.033 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 0.58 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 September 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 September 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.
November 2017 4 073-9603917

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
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 September 2017 Groundwater Monitoring Event
Golder personnel visited the facility on September 28 and 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 surface water monitoring points were either dry or had
no flowing water during this event. The facility’s leachate was sampled on October 2, 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
November 2017 5 073-9603917

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.
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 are typically collected either 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 are typically measured directly from the stream and recorded
during the collection of the surface water samples.
The leachate sample was collected by ENCO personnel on October 2, 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 September 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 September 29, 2017, and properly
preserved. The leachate sample was collected and transported to the laboratory in good condition on
October 2, 2017, and properly preserved.
2.5 September 2017 Sampling Results
Analytical results and field parameters for the September 2017 groundwater, surface water, and leachate
samples are summarized in Tables 4 through 8 along with available historical data. The laboratory
November 2017 6 073-9603917

certificates-of-analysis, chain-of-custody form, and laboratory data reviews for the sampling event are
included in Appendix B.
As presented, three NC Appendix I constituents (barium, silver, and zinc) were detected at concentrations
above their Solid Waste Section Limits (SWSLs) in samples from one or more downgradient compliance
wells during the September 2017 event. Surface water locations SW-1, SW-2, SW-3, SW-4, and SW-5
were not sampled during this event as the locations were noted as either dry or lacking flowing water.
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 September 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 September 2017
event, barium, copper, and thallium were detected in the field blank at estimated concentrations. Based
on Golder’s laboratory data review, the following concentrations are considered blank-qualified: copper at
MW-2, -4, -7, -8, and -9, thallium at MW-2, -3, -4, -5, -7, -8, and -9.
A laboratory method blank was also analyzed in conjunction with the October 2, 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, two constituents were detected above their respective SWSLs and groundwater
standards during this event: barium and chromium in the sample from upgradient well MW-1. No further
action is warranted for the background well as barium appears to be naturally occurring. Cobalt was
detected at an estimated concentration below the SWSL but above the SWS Groundwater Protection
Standard (GPS) in the sample from MW-5 during this event. Vanadium was detected at estimated
concentrations below the SWSLs but above the SWS 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 further action is warranted because concentrations are estimated below the SWSLs.
Thallium was detected at estimated concentrations below the SWSLs but above the Solid Waste Section
(SWS) Groundwater Protection Standard (GPS) in the samples from MW-2, -3, -4, -5, -7, -8, and -9, but
these concentrations are considered blank qualified. Thus, no further action is warranted.

November 2017 7 073-9603917

No NC Appendix I organic constituents were detected above the SWSLs and groundwater standards
during the September 2017 event. Surface water locations SW-1, SW-2, SW-3, SW-4, and SW-5 were
not sampled during this event as the locations were noted as either dry or lacking flowing water. Leachate
results were generally consistent with available historical data for this facility.
5.0 SUMMARY
Based on the results summarized herein, Wake County Disposal, LLC is in compliance with respect to
water quality monitoring requirements and will continue monitoring the uppermost aquifer beneath this
facility in accordance with the requirements of the Detection Monitoring Program as outlined in Title 15A
NCAC 13B.1633. The next groundwater monitoring event is tentatively scheduled for March 2018.

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) Selenium was diluted for MW-1 by 5X for the September 2017 event.

5.0 DATA REPORTING
WB All analytical reporting associated with the event was performed by the contracted lab.

WB 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.

 Field Blank
• Barium @ 3.09 ug/L (J)
• Copper @ 3.55 ug/L (J), B flags should be added to the following:
 MW-2 @ 2.65 ug/L (J)
 MW-4 @ 1.69 ug/L (J)
 MW-7 @ 2.57 ug/L (J)
 MW-8 @ 2.64 ug/L (J)
 MW-9 @ 2.21 ug/L (J)
• Thallium @ 0.212 ug/L (J), B flags should be added to the following:
 MW-2 @ 0.707 ug/L (J)
 MW-3 @ 0.610 ug/L (J)
 MW-4 @ 0.508 ug/L (J)
 MW-5 @ 0.536 ug/L (J)
 MW-7 @ 0.436 ug/L (J)
 MW-8 @ 0.318 ug/L (J)
 MW-9 @ 0.313 ug/L (J)
WB 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.

 Sample MW-1 was processed at a dilution for the analysis of Selenium (5x), due to high concentrations of non-target analytes, resulting in elevated reporting limits.
WB The report provides the reporting limit for each constituent.
WB The results were reported at or below their proper reporting limits (i.e., MDLs with SWSLs reported). 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.

WB Other report issues/Communications with laboratory/etc.:

 Per client email, the collection dates for samples MW-7, MW-8, and MW-9 were recorded incorrectly on the Chain of Custody. The correct collection date for these samples is September 29, 2017, not September 19, 2017.
 Samples SW-1, SW-2, SW-3, and SW-5 were not submitted for analysis, as the sources were dry at the time of collection. SW-4 was not submitted, as there was no flow at the time of collection.
