RE: WATER QUALITY MONITORING REPORT, SECOND SEMI-ANNUAL 2015 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 November 9 - 11, 2015, compliance monitoring
event, and December 30, 2015, verification event at the above-referenced facility.
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 (antimony, chromium, cobalt, copper, 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 November 2015
monitoring event. The concentrations of three of these metals (antimony, chromium, and cobalt) were also above the established groundwater standards; in addition, estimated cobalt and vanadium
concentrations below the SWSL were above applicable standards for one or more downgradient monitoring points. As allowed by 15A NCAC 13B. 1632 (g) and (h), statistical analyses were performed
to determine the source of above-standard, quanitfiable concentrations of antimony, chromium, and cobalt. Based on the statistical analyses, the antimony and chromium concentrations are below statistical
background limits, and do not warrant additional action. The cobalt detection at the GGI-1 Outfall, however, was statistically significant.
A verification sampling event was conducted on December 30, 2015, and the GGI-1 Outfall was re-sampled and analyzed for total and dissolved cobalt. The verification concentrations confirmed the initial
results, and do not appear to be biased significantly high by turbidity, although elevated turbidity was noted at the location during both sampling events (fine-grained particulates may bias metals results
high). Based on information provided by the site and their engineering firm, there was an apparent back-up within the Gravity Groundwater Intercept (GGI) system prior to the November event, which has since
been cleared. However, sediment build-up may take additional time to clear out. There were no leachate indicators noted for this sample or other atypical results aside from relatively high metals concentrations
as compared to historical data. Therefore, we recommend reviewing the results from the next semi-annual event to determine if additional action is warranted.
Mr. Ervin Lane January 29, 2016 NC Dept. of Environment & Natural Resources 2 073-9603715.100

As presented, five inorganic constituents (antimony, chromium, cobalt, copper, 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 November 2015
monitoring event. The concentrations of antimony, chromium, and cobalt in samples from one or more downgradient monitoring well were reported above the establish groundwater standard and the SWSL.
As allowed by 15A NCAC 13B. 1632 (g) and (h), statistical analyses were performed to determine the source of above-standard concentration of antimony, chromium, and cobalt reported in samples from one
or more downgradient monitoring point. Based on statistical analyses, the aforementioned concentrations are below statistical background and do not warrant additional action with the exception of cobalt at GGI-1
Outfall, which was statistically significant.
A verification sampling event was conducted on December 30, 2015, and GGI-1 Outfall was re-sampled
and analyzed for total and dissolved cobalt. Based on these results, the concentrations confirmed and do not appear to be biased significantly high by turbidity, although elevated turbidity was noted at the location
during both sampling events and fine-grained particulates may bias results high. Based on information provided by the Waste Industries and their engineering firm, there was a connection being made to the
GGI system during both the initial and re-sample time period in which a portion of the GGI system was open for connection and silt was known to have entered the system. The sediment has sediment in the
system was cleaned as best possible in early 2016; however, sediment build up may take additional time to clear out. There were no leachate indicators noted for this sample or other atypical results aside from
relatively high metals concentrations. Therefore, we recommend reviewing the results from the next semi-annual event to determine if additional action is warranted.
At the C&D facility, four NC Appendix I inorganic constituents (arsenic, barium, chromium, and copper)
were reported at concentrations greater than their respective SWSLs in samples from one or more downgradient monitoring wells during the November 2015 monitoring event. The concentrations of
arsenic and chromium were reported to be above the NC2L in samples from one or more downgradient monitoring well. Statistical analyses were performed to determine if the reported concentrations
represent statistically significant increases over background concentrations. Based on the results of the statistical analysis, the reported concentrations of arsenic and chromium were not statistically significant
and no further action is warranted.
Indicator parameters iron and manganese were also detected at concentrations above their respective
SWSLs and NC 2L Groundwater Standards in samples from one or more downgradient wells during the event, as they have been during previous events. Based on historical data and statistical analyses, no
further action is recommended. Cobalt and vanadium were reported in samples from one or more upgradient and/or downgradient C&D and MSW wells at estimated concentrations above the applicable
groundwater standards but below their respective SWSLs as they have been during previous events. No further action is required since concentrations are estimated, and data are similar to historical and/or
upgradient monitoring data.
No NC Appendix I VOCs were detected at concentrations above SWSLs during this monitoring event in
any compliance monitoring point. Zinc was detected at downstream points SW-4 and SW-5 at concentrations above the SWSL and applicable surface water standard during this event, as it has been
in the historically at SW-5, and may be biased high by turbidity induced by heavy rainfall prior to the sampling event. Silver and acetone were detected at estimated concentrations below the SWLs and
above the surface water standards at SW-5 during this event; no further action is warranted based on estimated concentrations. No NC other constituents were detected above the SWSLs or applicable
surface water standards in any surface water monitoring points during the November 2015 event. In the absence of leachate indicator parameters, no further action is warranted at this time. Also, leachate
results were generally consistent with historical data for this facility.
Based on these results, Sampson County Disposal, LLC will continue groundwater monitoring in
accordance with the requirements of the Detection Monitoring Program as outlined in Title 15A NCAC 13B.1633 and .0544. The next semi-annual monitoring event is tentatively scheduled for May 2016. If
you have any questions, please contact the undersigned at 336-852-4903.

1.0 INTRODUCTION
This report summarizes the monitoring results from the November 9 - 11, 2015, groundwater, surface
water, and leachate sampling and analysis 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 Environment and Natural Resources (DENR). 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
January 2016 2 073-9603715

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 North Carolina Department of Environment and
Natural Resources (NC DENR) 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. Based on the May 2015
data, there were no quantifiable detections of VOCs in the sample from MW-107S and therefore
MW-107D will not be sampled during the next scheduled compliance monitoring event.
The facility’s monitoring network also includes three surface water sampling points, SW-1, SW-4, and
SW-5. 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 North
Carolina. 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 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 2015
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 November 2015 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 0.006 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
January 2016 4 073-9603715

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 347.5 feet/year toward the northeast, which is generally consistent with previous estimates
(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 November 2015 sampling event are discussed in the following
sections.
2.1 Visual Inspection Program
In 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 November 2015 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
January 2016 5 073-9603715

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.
2.3 November 2015 Monitoring Event
Personnel from Golder visited the facility on November 9 - 11, 2015, 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. 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.
January 2016 6 073-9603715

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.
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 December 2015 Verification Groundwater Monitoring Event
Golder personnel visited the facility on December 30, 2015, to re-sample GGI-1 Outfall to verify
the cobalt concentration during the November 2015 event. The well was purged and sampled utilizing
techniques as those described above. After collection, the sample was placed in a cooler on ice, under
chain-of-custody control for analysis of total and dissolved cobalt. A copy of the sampling log is
presented in Appendix A. Included in the log is a description of the sampling equipment, sampling
method, field observations, location, and water quality measurements.
2.5 Laboratory Analysis Program
The November 2015 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.
2.6 November 2015 Sampling Results
Analytical results for the November 2015 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.
January 2016 7 073-9603715

As presented, seven inorganic constituents (antimony, chromium, cobalt, copper, 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 November 2015
monitoring event. At the C&D facility, four NC Appendix I inorganic constituents (arsenic, barium,
chromium, and copper) were detected at concentrations above their respective SWSLs in samples from
downgradient monitoring wells during the November 2015 monitoring event.
No NC Appendix I organic constituents were detected in samples from groundwater or surface water
monitoring points during the event above SWSLs. Barium, beryllium, cobalt, and zinc were detected at
one or more downstream monitoring points above the SWSLs during this event. Also, leachate results
were consistent with historical data for this facility.
2.7 December 2015 Verification Sampling Results
The sample collected on December 30, 2015 from GGI-1 was analyzed for total and dissolved cobalt.
Both concentrations were similar to the original value and indicate that if turbidity is biasing results high
as evidenced by relatively high field turbidity values, the particulates are fine-grained.
3.0 LABORATORY AND FIELD QA/QC
A field blank was collected by Golder personnel as part of the November 2015 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. No constituents were detected in the
method blank or field blank during this event and no data qualification was necessary.
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 antimony, chromium, and cobalt exceeded the groundwater
standards and SWSLs during this event at one or more downgradient well. As described below, the
concentrations of antimony and 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 is described further below. Cobalt and vanadium
were reported at estimated concentrations below the SWSLs but above the Solid Waste Section Standard
(SWS GWPS) 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.
January 2016 8 073-9603715

At the C&D facility, arsenic and chromium were reported at quantifiable concentrations above the NC 2L
Standard in the samples collected from one or more downgradient wells during this event. As described
below, the concentrations of arsenic and chromium were determined to be below background 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.
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. Zinc was detected at downstream monitoring points SW-4 and SW-5 during this event above
the SWSL and applicable surface water standard; concentrations may be biased high by turbidity due to
heavy rains preceding the sampling event. Silver and acetone were also detected at SW-5 at estimated
concentrations below the SWSLs but above applicable groundwater standards. No other NC Appendix I
constituents were reported above applicable surface water standards from samples collected from the
downstream surface water monitoring points during the November 2015 event.
4.2 Statistical Evaluations
As presented above, antimony, cobalt, and chromium at the active MSW facility and arsenic, chromium,
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 November 2015 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, which
was statistically significant. Verification sampling confirmed the original results and total and dissolved
concentrations were similar; however, the field turbidity values were high for the November and
December 2015 sampling events.
5.0 CONCLUSIONS
The above-standard concentrations of cobalt at GGI-1 Outfall do not appear to be biased significantly
high by turbidity, although elevated turbidity was noted at the location during both sampling events and
fine-grained particulates may bias results high. Based on information provided by the Waste Industries
and their engineering firm, there was a connection being made to the GGI system during both the initial
and re-sample time period in which a portion of the GGI system was open for connection and silt was

known to have entered the system. The sediment has sediment in the system was cleaned as best
possible in early 2016; however, sediment build up may take additional time to clear out. There were no
leachate indicators noted for this sample or other atypical results aside from relatively high metals
concentrations. Therefore, we recommend reviewing the results from the next semi-annual event to
determine if additional action is warranted.

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 May 2016.

3.0 LABORATORY QUALITY CONTROL REVIEW
TM Laboratory analyzed at least one internal blank for each method, where applicable.
TM Laboratory blank is interference-free.
TM Surrogate recoveries are provided for each analytical method, where applicable.
TM Surrogate recoveries for each method are within the acceptable limits (i.e., at least 50% of the surrogates were within range).
• The 8260B surrogate spike recovery of Dibromofluoromethane exceeded acceptance criteria for one of the Method Blanks and sample MW-103A (MS/MSD). These samples were
approved based on acceptable recovery of the other surrogate standards.
TM MS/MSD/LCS data results are provided for each analytical method.
TM MS/MSD/LCS recoveries for each method are within the acceptable limits (i.e., at least 1 of
the 3 were within range).
• The spike recovery of Trichloroethene exhibited a high bias for the 8260B LCS samples;
however, this analyte was not detected in the associated samples, reducing the impact of the deviation. The spike recoveries of 1,1-Dichloroethene, Toluene, and Trichloroethene
were outside of control limits for the 8260B MS and or MSD samples. The QC batches were approved based on acceptable LCS recovery of these analytes.
4.0 ANALYTE LISTS/METHODS

TM The proper number of constituents are present for each analyte list as identified above
(including detects where applicable).
TM Proper EPA SW-846 analytical methods were used for analysis.
5.0 DATA REPORTING TM All analytical reporting associated with the event was performed by the contracted lab.
TM 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.

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.
• MW-108: Thallium 10x
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.
TM No inorganic or organic constituents were reported above their respective NC 2L Drinking
Water Standards or Groundwater Protection Standards (GWPS) in wells or field/equipment/trip blanks or Surface Water Standards for surface points.

TM No inorganic or organic constituents were detected in a well or surface water point at quantified concentrations outside of their historical range (more than 5X previous
concentrations or first-time detections).
TM Other report issues/Communications with laboratory/etc.:
• MW-108 was processed at dilution for the analysis for Thallium due to matrix interference,
resulting in elevated reporting limits.
