RE: WATER QUALITY MONITORING REPORT, FIRST SEMI-ANNUAL 2016 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 10 - 11, 2016, compliance monitoring event and July 7, 2016, 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 only 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.
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 2016 monitoring event. The concentrations of two of these metals (chromium and cobalt) were above the established
groundwater standards. As allowed by 15A NCAC 13B. 1632 (g) and (h), statistical analyses were performed to determine the source of above-standard, quantifiable concentrations of chromium and
cobalt. Based on the statistical analyses, the chromium concentrations are below statistical background limits, and do not warrant additional action. The cobalt detection at the GGI-1 Outfall was determined to
be statistically significant.
GGI-1 outfall was re-sampled on July 7, 2016, for analysis of total and dissolved cobalt. Based on the re-
sampling data, the total and dissolved cobalt concentrations are below the statistical background value and no further action is warranted as they are likely naturally occurring. During this event, antimony,
cobalt, and vanadium were detected at concentrations below their respective SWSLs and above applicable standards at one or more downgradient monitoring points; no additional action is warranted for
these estimated concentrations, which are similar to historical concentrations.
At the C&D facility, four NC Appendix I inorganic constituents (barium, chromium, cobalt, and copper)
were reported at concentrations greater than their respective SWSLs in samples from one or more downgradient monitoring wells during the May 2016 monitoring event. The concentrations of cobalt and
chromium were reported to be above their respective groundwater in samples from one or more downgradient monitoring points. Indicator parameters iron and manganese were also detected above
their respective groundwater standards in samples from one or more downgradient monitoring wells. Statistical analyses were performed to determine the source of the above-standard concentrations.

1.0 INTRODUCTION
This report summarizes the monitoring results from the May 10 - 11, 2016, groundwater, surface water,
and leachate sampling and analysis event and July 7, 2016, verification monitoring event at the active
Sampson County, LLC Municipal Solid Waste (MSW) and Construction & Demolition (C&D) Landfills in
Sampson County. 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 2016 2 073-9603716

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. Recent data for samples from MW-107S and MW-107D indicate that
concentrations of VOCs in groundwater samples are below SWSLs and that these corrective measures
have 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 2016 3 073-9603716

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 May 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 2016 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 0.007 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 367 feet/year toward the northeast, which is generally consistent with previous estimates
July 2016 4 073-9603716

(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 2016 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 2016 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 2016 5 073-9603716

2.3 May 2016 Monitoring Event
Personnel from Golder visited the facility on May 10 - 11, 2016, to purge and sample monitoring wells, to
sample the gravity groundwater intercepts, surface water monitoring points, and the facility’s leachate
collection system. Surface water monitoring point SW-5 was dry during this event and no sample was
collected.
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. 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® or bladder
pump’s 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 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 2016 6 073-9603716

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 July 2016 Verification Groundwater Monitoring Event
Golder personnel visited the facility on July 7, 2016, to re-sample GGI-1 Outfall to verify the cobalt
concentration observed during the May 2016 event, re-sample MW-5AN to verify the chromium and
cobalt concentrations. 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 for analysis of
total and dissolved cobalt. 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 2016 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 July 2016 verification samples were also submitted to ENCO. The sample from GGI-1 Outfall was
analyzed for cobalt and the sample from MW-5AN was analyzed for chromium and cobalt. The samples
were received at the laboratory in good condition and were properly preserved.
2.6 May 2016 Sampling Results
Analytical results for the May 2016 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 2016 monitoring
event. At the C&D facility, four NC Appendix I inorganic constituents (barium, chromium, cobalt, and
July 2016 7 073-9603716

copper) were detected at concentrations above their respective SWSLs in samples from downgradient
monitoring wells during the May 2016 monitoring event.
No NC Appendix I organic constituents were detected in samples from groundwater monitoring points
during the event above SWSLs. No NC Appendix I constituents were detected above the SWSLs at
surface water monitoring points during this event. Also, leachate results were consistent with historical
data for this facility.
2.7 July 2016 Verification Sampling Results
The samples collected on July 7, 2016 were analyzed as follows: GGI-1 (total and dissolved cobalt) and
MW-5AN (total and dissolved chromium and cobalt). Concentrations were below original detections as
described below.
3.0 LABORATORY AND FIELD QA/QC
A field blank was collected by Golder personnel as part of the May 2016 groundwater 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 during this event. The
following copper concentrations are considered blank-qualified: MW-106, MW-107, MW-108,
GGI Outfall 1, GGI Outfall 2, and SW-4.
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, concentrations of chromium and cobalt exceeded their respective groundwater
standards and SWSLs during this event at one or more downgradient wells. As described below, the
concentrations of chromium were determined to be below background and no further action is warranted.
The concentration of cobalt was determined to represent a statistically significant increase over
background concentrations at GGI-1 Outfall and was not confirmed during verification sampling.
Antimony, 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 since concentrations are estimated and consistent with
historical data.
At the C&D facility, chromium and cobalt were reported at quantifiable concentrations above their
respective groundwater standards in the samples collected from one or more downgradient wells during
this event. As described below, the concentrations of chromium and cobalt were statistically determined
July 2016 8 073-9603716

to be above background. Verification results were below background values and no further action is
warranted. Cobalt and vanadium were also reported at estimated concentrations below the SWSLs, but
above applicable groundwater standards in one or more monitoring points during this event; no further
action is required for these detections because the concentrations are estimated and consistent with
historical data.
Indicator parameters iron and manganese were reported at concentrations above their respective SWSLs
and NC 2L Groundwater Standards in samples from one or more downgradient C&D wells during the
event, as they have been during previous events and appear to be naturally occurring based on statistical
analysis. No NC Appendix I constituents were reported above applicable surface water standards from
samples collected from the downstream surface water monitoring points during the May 2016 event.
4.2 Statistical Evaluations
As presented above, cobalt and chromium at the active MSW facility and chromium, cobalt, iron, and
manganese at the active C&D facility were detected above their respective SWSLs and applicable
groundwater standards in samples from one or more downgradient compliance monitoring points during
the May 2016 monitoring event. In order to determine the source of these concentrations, statistical
analyses were performed as allowed by 15A NCAC 13B.1632 (g) and (h). The concentrations of the
constituents detected in downgradient monitoring wells were statistically evaluated to determine if the
reported concentrations exceeded the facility background concentrations. The summary tables for
statistical analyses and statistical worksheets are presented as Appendix C.

Based on statistical evaluations, the concentrations of the aforementioned metals are below background
and appear to be naturally occurring, with the exception of cobalt in the sample from GGI Outfall 1, and
chromium and cobalt in the sample from MW-5AN, which were statistically significant. Verification
sampling results were below statistical background and therefore appear to be naturally occurring. The
relatively low pH values at the facility and naturally occurring metals often result in statistical anomalies.
No further action is warranted.
5.0 CONCLUSIONS
The above-standard concentrations of cobalt at GGI-1 Outfall and chromium and cobalt at MW-5AN
appear to be naturally occurring based on statistical analyses; the low pH values and naturally occurring
metals at the site often result in false statistical exceedances. Based on 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 2016.

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, Copper @ 2.90 ug/L (J)

TM It is clear from the laboratory report that samples have or have not been diluted during analysis, and if the samples have been diluted, the result is reported as a multiple of the
dilution (e.g., a sample diluted 10x resulting in an analytical detection of 1.0 should be reported as 10). Those that have been diluted are listed below with the dilution factor.
Leachate (L-1)
VOC’s, Antimony and Thallium x50, other metals x5, COD x20, Phosphorous x5, Chloride and Total Alkalinity x5
TM The report provides the reporting limit for each constituent.
TM The results were reported at or below their proper reporting limits (e.g., NC Solid Waste
Section Approved QLs). Those that are not reported correctly are listed below (by constituent) with the proper reporting limit listed beside them. State if the reporting limit error
is due to dilutions.

N/A No inorganic or organic constituents were reported above their respective NC 2L Drinking Water Standards or Groundwater Protection Standards in field/equipment/trip blanks or
Surface Water Standards in surface points.
TM No quantifiable inorganic or organic constituents were detected in a well or surface water point at concentrations outside of their historical range (more than 5X previous concentrations or
first-time detections).
TM Other report issues/Communications with laboratory/etc.:
• The average dissolved oxygen uptake of the seeded BOD control did not meet the method requirement of 0.6 to 1.0 mg/L. Due to method constraints, the test cannot be repeated, and the reported results should be considered estimated.
