RE: WATER QUALITY MONITORING REPORT, FIRST SEMI-ANNUAL 2017 SAMPLING EVENT SAMPSON COUNTY DISPOSAL, LLC ACTIVE MSW AND C&D LANDFILLS PERMIT NO. 82-02 SAMPSON COUNTY, NORTH CAROLINA
Dear Ervin,
On behalf of Sampson County Disposal, LLC (Sampson County), a subsidiary of Waste Industries USA, Inc. (Waste Industries), Golder Associates NC, Inc. (Golder) is submitting the enclosed Water Quality
Monitoring Report, which documents the results of the May 8 - 10, 2017, compliance monitoring event and June 23, 2017, verification monitoring event.
Groundwater, surface water, and leachate samples were analyzed for North Carolina (NC) Appendix I constituents, with the exception of MW-100B, which was analyzed for the NC Appendix I list of inorganic
constituents per the approved monitoring plan. Samples for the Construction and Demolition (C&D) landfill wells were also analyzed for the other required parameters for C&D landfills, as specified in Title
15A NCAC 13B.0544 including tetrahydrofuran, and the leachate sample was also analyzed for additional required parameters.
At the MSW facility, five inorganic constituents (beryllium, chromium, cobalt, nickel, and zinc) were detected at concentrations above their respective Solid Waste Section Limits (SWSLs) in samples from
one or more downgradient compliance monitoring points at the active MSW landfill during the May 2017 monitoring event. The concentrations of two of these metals (chromium and cobalt) were above the
established groundwater standards as reported in the 14-day notification/Alternate Source Demonstration (ASD) dated July 19, 2017 but are interpreted to be naturally occurring based on available data.
Estimated concentrations of cobalt and vanadium were also reported to be above their respective groundwater standards but below the SWSLs in samples from one or more downgradient monitoring
points; no further action is warranted for these estimated concentrations.
One organic constituent (toluene) was detected at concentrations above the SWSL in the sample from
downgradient compliance monitoring point MW-106. During the June verification event, no toluene was detected at MW-106 and the original result is considered suspect.
At the C&D facility, six NC Appendix I inorganic constituents (barium, chromium, cobalt, copper, vanadium, and zinc) were reported at concentrations greater than their respective SWSLs in samples
from one or more downgradient monitoring wells during the May 2017 monitoring event. Indicator parameters iron and manganese were also detected above their respective SWSLs and groundwater
standards in samples from one or more downgradient monitoring wells during this event. The concentrations of chromium, cobalt, iron, manganese, and vanadium were above their respective
groundwater standards as reported in the 14-day notification/ASD dated July 19, 2017. The dissolved concentration of vanadium for MW-4N was non-detect; the total vanadium concentration is interpreted to
be biased high by entrained sediment as evidenced by relatively high field turbidity values. Well re-development is recommended for MW-4N prior to the next compliance monitoring event. Estimated
concentrations of cobalt and vanadium were also reported to be above their respective groundwater standards but below the SWSLs in samples from one or more downgradient monitoring points; no further

1.0 INTRODUCTION
This report summarizes the monitoring results from the May 8 - 10, 2017, groundwater, surface water,
and leachate sampling at the active Sampson County, LLC Municipal Solid Waste (MSW) and
Construction & Demolition (C&D) Landfills in Sampson County as well as the results of the June 23, 2017,
verification sampling. The active MSW Landfill facility is a Subtitle D facility and is monitored in
accordance with Title 15A of the North Carolina Administrative Code (NCAC) Subchapter 13B.1633.
Groundwater at the closed C&D Landfill is monitored in accordance with Title 15A NCAC 13B.0544.
The facility is located on the northern half of the Sampson County Landfill property and is comprised of
the Phase 1 active Subtitle D lined MSW landfill and one active C&D landfill. The facility is owned and
operated by Sampson County, LLC, a subsidiary of Waste Industries, Inc., under Permit No. 82-02 issued
by the North Carolina (NC) Department of Environmental Quality (DEQ, formerly NC Department of
Environment and Natural Resources). The southern half of the landfill property is comprised of one
closed Subtitle D lined MSW landfill and one closed C&D landfill, which are covered under Permit No. 82-
01. The results for the closed facility are submitted under separate cover.
1.1 Site Description and Background
The location of the facility is shown on the inlay on Drawing 1. The Sampson County Landfill is located
approximately 6.5 miles west of Clinton, North Carolina in Sampson County near the rural community of
Snow Hill. Access to the site is from Roseboro Highway (N.C. Highway 24), south of the site.
The Bearskin Swamp is located along the eastern property boundary and drains to the southwest into
Little Coharie Creek. The location of this surface water feature is shown on Drawing 1.
Based on the topography as shown on Drawing 1, topographic surface elevations at the facility range
from approximately 130 feet above mean sea level (AMSL) along the perimeter of the C&D disposal area
on the southeastern portion of the facility, to nearly 250 feet AMSL in the southeastern portion of the
MSW disposal area. The site is surrounded predominantly by wooded, agricultural, or rural residential
properties.
The Permit 82-01 closed MSW and C&D landfills are located south of the active landfills. The property
also includes a closed, unlined disposal area owned and maintained by Sampson County. This area is
located south of the active facility. Roseboro Highway (N.C. Highway 24) is located to the south of the
active landfills.
1.2 Compliance Monitoring History
Groundwater monitoring at the facility was initiated in October 1996. The facility’s approved MSW
monitoring network is currently comprised of eight monitoring wells, which monitor the uppermost aquifer
beneath the facility. Monitoring wells MW-102A and MW-103A are the upgradient background wells for
the MSW landfill. An additional upgradient background well (MW-100B) is monitored for NC Appendix I
July 2017 2 073-9603717

inorganic constituents. Monitoring well MW-100B was installed as a replacement well MW-100A prior to
the May 2010 sampling event due to site construction activities. Wells MW-104, MW-105A, MW-106,
MW-107S, and MW-108 are downgradient compliance wells for the MSW landfill. Additionally, upgradient
well MW-1N and downgradient wells MW-2N, MW-3N, MW-4N, MW-5AN, and MW-5BN monitor
groundwater at the C&D landfill.
Groundwater beneath the two disposal units is currently monitored by a combined total of 14 monitoring
wells. In addition to the wells, groundwater quality is also monitored at GGI Outfalls 1 and 2, gravity
groundwater intercept outfall sampling locations. GGI Outfall 1 is located east of the MSW disposal area,
while GGI Outfall 2 is located north of the MSW, both outfalls discharging into wetland areas.
Monitoring well MW-107D had been sampled in previous events as part of an assessment of volatile
organic constituents (VOCs) detected in MW-107S. Historical analytical results for samples from
MW-107S and MW-107D indicate that VOCs have been present in groundwater, and may be related to
landfill gas impacts to groundwater and/or historical leachate seeps along the adjacent side slopes as
discussed in the September 20, 2007, meeting with the Solid Waste Section. The corrective action for
these potential sources was implemented with the initial installation of several active gas extraction wells
during final capping activities, as well as the installation of additional landfill gas extraction wells near the
eastern slope of the facility. Data for samples from MW-107S and MW-107D indicated that
concentrations of VOCs in groundwater samples are below SWSLs and that these corrective measures
improved groundwater quality in this area. The NC DEQ granted approval to discontinue sampling
monitoring well MW-107D in electronic correspondence dated October 24, 2012. The approval to
discontinue sampling MW-107D is contingent upon being able to collect a sample from MW-107S and
that no quantifiable detections of VOCs are reported in the sample collected from MW-107S. If
MW-107S is dry, or if VOCs are reported at quantifiable concentrations, then the facility must resume
sampling MW-107D.
The facility’s monitoring network also includes three surface water sampling points, SW-1, SW-4, and
SW-5. Surface water point SW-1 is the facility’s upstream sampling point located along Bearskin Swamp
north of the active facility. Surface water point SW-4 is located downstream and north of the MSW
disposal area along an unnamed tributary to the Bearskin Swamp. Surface water point SW-5 is a second
downstream sampling location located east of the active facility in a drainage channel into the wetlands
area. Surface points SW-1, SW-4, and SW-5 are sampled in conjunction with the groundwater monitoring
wells in accordance with the facility’s permit and Water Quality Monitoring Plan.
1.3 Hydrogeologic Setting
The facility is located in the western portion of the Coastal Plain Physiographic Province of NC. The
geologic units of this region are relatively young, dating from the Cretaceous Period to the present, and
have been formed through transgression and regression of the Atlantic Ocean. The natural topography is
July 2017 3 073-9603717

flat to gently rolling with the upland surfaces gradually sloping downward in a southeasterly direction
(S&ME 1992). The site is underlain by sands, silts, and clays of the Black Creek Formation, which
consists of crossbedded layers of black to gray thinly-laminated clay and sand lenses of varied thickness
and grain size. The formation is rich in mica, lignite, and iron sulfides. The Tuscaloosa formation
underlies the Black Creek Formation and is comprised of gray to white sand and gravel with clay lenses
(NCGS 1985). An unconformity forms the contact between the two formations with some interfingering of
the two layers in the transition zone (NCGS 1960).
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. Beneath the uppermost aquifer, a clay
confining layer is present generally at a depth of approximately 20 - 25 feet below ground surface (BGS).
The clay confining layer generally consists of black or dark gray silty clay with thin seams of light gray fine
sand (S&ME 1992). Groundwater occurs at depths varying from approximately 4 - 16 feet BGS (plus or
minus) across the entire site. Depth-to-water measurements obtained during the November 2016
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 northeast and east toward Bearskin
Swamp located along the eastern property boundary. The Bearskin Swamp flows south to southwest and
drains into Little Coharie Creek, located approximately two miles southwest of the facility. The
groundwater contour map and interpreted flow directions are generally consistent with previously
submitted interpretations for this facility.
Based on the May 2017 groundwater 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 0.008 feet/foot. Groundwater velocities were calculated using a hydraulic
conductivity of 1.295 X 10-2 centimeters per second (cm/s), which is the average of the hydraulic
conductivities calculated for the hydrogeologic units present at the facility (GNRA December 1999). The
estimated effective porosity of the shallow aquifer is also based on the average of the effective porosities
for the hydrogeologic units, which is 0.25 (GNRA December 1999).
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 unit is
approximately 412 feet/year toward the northeast, which is generally consistent with previous estimates
July 2017 4 073-9603717

(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 May 2017 sampling event are discussed in the following sections.
2.1 Visual Inspection Program
In order to detect a potential release at the earliest possible time, the visual inspection program is used at
the active MSW and 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 May 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 14 wells and two gravity
groundwater intercept outfalls. 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, and to monitor for potential releases from the landfill unit. One upstream surface
water monitoring point (SW-1) and two downstream surface water monitoring points (SW-4 and SW-5)
are also monitored.
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 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 5 - 10 feet (plus or minus) under normal conditions. The range in fluctuation appears to
be greatest in the upgradient background wells, MW-102A and MW-103A, which are located in a
groundwater recharge area. 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.
July 2017 5 073-9603717

2.3 May 2017 Monitoring Event
Personnel from Golder visited the facility on May 8 – 10, 2017, to purge and sample monitoring wells, to
sample the gravity groundwater intercepts, surface water monitoring points, and the facility’s leachate
collection system.
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. The historical groundwater level elevation data are
also shown on this table.
Monitoring wells were purged and sampled using the dedicated pumps at the facility following low-flow
micropurge procedures. MW-102A was purged dry and then sampled the following day using a
disposable bailer as the water level was too low to utilize the dedicated pump. Measurements of
temperature, pH, specific conductivity, turbidity, dissolved oxygen, and oxidation reduction potential were
recorded on approximately 3-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 500 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 required groundwater samples were collected directly from the dedicated Grundfos®, bladder pump’s
discharge lines, or bailer 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 and location, field observations, and water quality measurements.
The surface water samples were collected directly from the stream, by lowering the sample containers
into the stream flow with the opening facing away from the current flow, taking care to prevent the
overflow of the sample containers and to minimize sample-induced turbidity. Measurements of
temperature, pH, specific conductivity, 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 directly from the leachate piping manifold in the area that serves as
secondary containment for the leachate transportation vehicles. Measurements of temperature, pH,
specific conductivity, and turbidity were recorded during the collection of the leachate sample.
July 2017 6 073-9603717

After collection, the surface water and leachate 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 location, sampling method, field observations, and water
quality measurements.
2.4 June 2017 Verification Groundwater Monitoring Event
Golder personnel visited the facility on June 23, 2017, to re-sample MW-106 at the MSW landfill to verify
the toluene concentration observed during the May 2017 event. Additionally, surface water point SW-4
was re-sampled to verify the copper, lead and zinc concentrations observed during the May 2017 event.
Samples were collected utilizing techniques as those described above.
After collection, the samples were placed in a cooler on ice, under chain-of-custody control. A copy of
the sampling logs are included in Appendix A. Included on the logs is a description of the sampling
equipment, sampling method, field observations, location, and water quality measurements.
2.5 Laboratory Analysis Program
The May and June 2017 groundwater, surface water, and leachate samples were submitted to
Environmental Conservation Laboratories, Inc. (ENCO) of Cary, North Carolina under chain-of-custody
control for analysis. As presented, groundwater, surface water, and leachate samples at the facility were
analyzed for NC Appendix I constituents, with the exception of MW-100B which is only analyzed for the
NC Appendix I list of inorganic constituents. Samples from C&D wells MW-1N, MW-2N, MW-3N, MW-4N,
MW-5AN, and MW-5BN were also analyzed for other required parameters for C&D landfills, as specified
in Title 15A NCAC 13B.0544, including tetrahydrofuran. The leachate sample was also analyzed for the
other required leachate parameters. The samples were received at the laboratory in good condition and
were properly preserved. The verification samples were analyzed as follows: toluene for MW-106 and
copper, lead and zinc for SW-4.
2.6 May 2017 Sampling Results
Analytical results for the May 2017 groundwater, surface water, and leachate samples are summarized in
Tables 4, 5, 6, 7, 8, 9, and 10 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, five inorganic constituents (beryllium, chromium, cobalt, nickel, and zinc) were detected at
concentrations above their respective Solid Waste Section Limits (SWSLs) in samples from one or more
downgradient compliance monitoring points at the active MSW landfill during the May 2017 monitoring
event. One organic constituent (toluene) was also detected at MW-106. At the C&D facility, six NC
Appendix I inorganic constituents (barium, chromium, cobalt, copper, vanadium, and zinc) were reported
at concentrations greater than their respective SWSLs in samples from one or more downgradient
monitoring wells during the May 2017 monitoring event. Additionally, several indicator parameters
July 2017 7 073-9603717

including iron and manganese were also reported at concentrations above SWSLs in samples from
downgradient monitoring wells during the May 2017 event. No other NC appendix I constituents were
detected above the SWSLs during this event.
Chromium, copper, lead, and zinc were detected at downstream monitoring point SW-4 during this event
at concentrations above their respective SWSLs and applicable surface water standards. No other NC
Appendix I constituents were detected above the SWSLs at surface water monitoring points during this
event. Leachate results were consistent with historical data for this facility.
2.7 June 2017 Verification Sampling Results
As presented, toluene for MW-106 was not confirmed during the June 2017 verification event as it was
non-detect. Zinc was the only NC Appendix I metal detected above the SWSLs during the verification
event for SW-4 but at a significantly lower concentration than originally reported. The laboratory
certificates-of-analysis, chain-of-custody form, and laboratory data reviews for the sampling event are
included in Appendix B.
3.0 LABORATORY AND FIELD QA/QC
A field blank was collected by Golder personnel as part of the May 2017 groundwater sampling and June
2017 verification sampling events. 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. Copper was
detected in the field blank at estimated concentrations during this event. The following copper
concentrations are considered blank-qualified: MW-100B, MW-102A, MW-103A, MW-106, MW-107S,
MW-108, GGI Outfall 1 MW-4N, MW-5AN, and SW-5. Acetone was detected in the trip blank. The
acetone concentration in MW-103A is considered blank-qualified and suspect.
4.0 DATA EVALUATION
The results of the data evaluations are presented in the following sections.
4.1 North Carolina Groundwater and Surface Water Standard Comparisons
At the MSW facility, the concentrations of chromium and cobalt were above the established groundwater
standards at one or more downgradient wells as reported in the 14-day notification dated July 19, 2017.
Estimated concentrations of cobalt and vanadium are above their respective groundwater standards but
below the SWSLs in samples from one or more downgradient monitoring points at the MSW facility; no
further action is warranted for these estimated concentrations. No other NC Appendix I constituents were
reported above applicable groundwater standards at the active MSW facility during this event.
July 2017 8 073-9603717

At the C&D facility, chromium, cobalt, iron, manganese, and vanadium were reported at quantifiable
concentrations above their respective groundwater standards and SWSLs in the samples collected from
one or more downgradient wells during this event. The dissolved concentration of vanadium for MW-4AN
was non-detect; the total vanadium concentration is interpreted to be biased high by entrained sediment
as evidenced by relatively high field turbidity values. Well re-development is recommended for this well
prior to the next compliance monitoring event. Cobalt and vanadium were reported at estimated
concentrations below the SWSLs, but above their respective groundwater standards in samples from one
or more downgradient monitoring points during this event; no further action is required because
concentrations are estimated and consistent with historical data. No other NC Appendix I constituents
were reported above applicable groundwater standards at the C&D facility during this event.
Copper, lead, and zinc were detected at concentrations above their respective surface water standards in
downstream monitoring point SW-4 during the May 2017 event. During the verification event, copper was
detected at an estimated concentration below the SWSL above the freshwater acute standard and below
the chronic standard at SW-4 and dissolved copper concentrations are below the SWSL and applicable
standards. Also, the lead concentration at SW-4 was below the SWSL and estimated above the
freshwater chronic standard; dissolved lead was non-detect. During the verification event, the total zinc
concentration was above the applicable standards at SW-4 but the dissolved zinc concentration was
below the standards. Heavy rains preceding the sampling events may be biasing metals results high.
Future results will be evaluated to determine trends and in the interim, erosion and sediment control
measures will be re-evaluated in the vicinity of this sampling point. No other NC Appendix I constituents
were reported above applicable surface water standards from surface water points during the May 2017
event.
4.2 Additional Evaluations
As described in the ASD (submitted under separate cover), above-standard metals concentrations in
samples from downgradient monitoring points are assumed to be naturally occurring, and are likely
exacerbated by the low (i.e. 2 – 6 specific units) pH values common at the site in groundwater samples
from both upgradient and downgradient locations. Alternate groundwater protection standards are also
submitted as part of the ASDs as allowed under NCAC Subchapter 15A NCAC 13B.1632(g).
5.0 CONCLUSIONS
The above-standard concentrations of several Appendix I inorganic constituents at several downgradient
wells at both the MSW and C&D Landfills appear to be naturally occurring based on information
presented in the July 19, 2017 14-day notification/ASD. Future results for SW-4 will continue to be
monitored and erosion and sediment control measures will be evaluated in the borrow area associated
with active cell construction in the vicinity of this sampling point and improved if necessary. We
recommend that MW-4N be re-developed prior to the next scheduled compliance monitoring event based
on relatively high field turbidity values, which are biasing metals results high at this location. Based on
July 2017 9 073-9603717

the results summarized herein, Sampson County Disposal, LLC 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 and .0544. The next sampling event is tentatively scheduled for
November 2017.
