RE: WATER QUALITY MONITORING REPORT
SECOND SEMI-ANNUAL 2016 SAMPLING EVENT
WASTE INDUSTRIES OF HIGH POINT C&D LANDFILL, PERMIT NO. 41-16
GUILFORD COUNTY, NORTH CAROLINA
Dear Jackie:
Golder Associates NC, Inc. (Golder), on behalf of Waste Industries, is submitting the enclosed Water
Quality Monitoring Report, which documents the results of the July 14 - 15, 2016, semi-annual compliance
monitoring event and the August 4, 2016, verification sampling event at the Waste Industries of High Point Construction and Demolition Landfill.
During the second semi-annual event, the concentrations of cobalt in the samples from downgradient wells MW-2 and MW-6 exceeded the Solid Waste Section Limit (SWSL) and Solid Waste Section Groundwater
Protection Standard (GPS). The cobalt concentrations from samples MW-2 and MW-6 were statistically compared to background concentrations and were determined not to represent statistically significant
increases over background concentrations. Therefore, cobalt is considered to be naturally occurring and no further action is warranted.
Cobalt was also detected in the sample from downgradient well MW-8 at concentrations below the SWSL, but above the GPS. Thallium was detected in samples from upgradient well MW-1 and downgradient wells
MW-3, MW-4S, MW-5, MW-7S, and MW-8 at concentrations below the SWSL, but above the GPS. Vanadium was detected in samples from downgradient wells MW-4S, MW-6, and MW-7S at concentrations
below the SWSL, but above the GPS. The concentrations of cobalt and vanadium are similar to historical data and are considered to be representative of natural conditions; because they are estimated below the
SWSLs, no further action is warranted. Many of the concentrations of thallium are first time detections, but since they are below the SWSL, no further action is warranted.
Indicator parameters iron and manganese were detected in samples from several downgradient wells at concentrations that exceeded their respective SWSL and NC 2L Standards, as they have during previous
events. Total dissolved solids (TDS) were detected in the sample from MW-6 at a quantifiable concentration that exceeded the NC 2L Standard. The iron, manganese, and TDS concentrations were statistically
compared to background concentrations and were determined not to represent statistically significant increases over background concentrations. Based on the available data, these concentrations are
considered to be representative of background conditions.
Benzene was detected above the SWSL and at or above the NC 2L Standard in the samples from MW-2
and MW-6 during the July 2016 event. The concentrations of benzene were confirmed during a verification event performed on August 4, 2016.
No NC Appendix I inorganic or organic constituents were detected at concentrations that exceeded applicable surface water standards during the event. The heavy sediment loads from an upstream source
were not present during the July 2016 event.
Pore water sampling was performed during the July 2016 event per the request the North Carolina
Department of Environmental Quality to evaluate water quality downgradient of MW-2. The samples

1.0 INTRODUCTION
This report summarizes the monitoring results from the July 14 - 15, 2016, groundwater and surface water
sampling and analysis event and the August 4, 2016, verification sampling event at the Waste Industries of
High Point Construction & Demolition (C&D) Landfill in Guilford County, North Carolina (NC) in accordance
with Title 15A of the North Carolina Administrative Code (NCAC) Subchapter 13B.0545. The active C&D
Landfill is owned and operated by Waste Industries under Permit No. 41-16 issued by the NC Department
of Environmental Quality (DEQ).
1.1 Site Description and Background
The location of the facility is shown on the inlay on Drawing 1. As presented, the Waste Industries of High
Point C&D Landfill is located along Riverdale Road within the city limits of Jamestown in Guilford County,
NC. The site consists of approximately 154 acres, of which, approximately 17.2 acres is currently permitted
as the Phase 1 and Phase 2 waste units.
There are three small unnamed streams that traverse the site and flow into an unnamed tributary of
Richland Creek, which forms the southern property boundary as shown on Drawing 1. The first unnamed
tributary is a southwest trending stream that forms the northwestern property boundary. The second
tributary is a southwest trending drainage in the center of the property and lies just east of the Phase 2
waste unit. The third tributary is a southwest trending drainage in the eastern portion of the site. A large
man-made pond is located near the eastern property boundary. A small storm water basin was constructed
in the northwest corner of the facility and a larger storm water basin was constructed along the southwestern
part of the site during the construction of Phase 1.
Topographic surface elevations at the facility range from approximately 700 to 820 feet above mean sea
level. The western portion of the site mainly consisted of trees and heavy brush before Phase 1 of the C&D
landfill was constructed. Now, most of that area consists of landfill operations. The eastern portion of the
site has historically been used for agricultural purposes. A reclamation facility is located at the northernmost
part of the site. A large portion of the surrounding properties are agricultural, sparse residential, or owned
by the City of High Point for operations associated with Kersey Valley Landfill.
1.2 Compliance Monitoring History
Groundwater monitoring at the facility was initiated in October 2003 after approval of the Groundwater
Monitoring Plan by the NC DEQ. Currently the facility’s monitoring network is comprised of eight monitoring
wells (MW-1, MW-2, MW-3, MW-4S, MW-5, MW-6, MW-7S, and MW-8), which monitor the uppermost
aquifer beneath the facility. Monitoring wells MW-7S and MW-8 were installed in July 2006 to monitor the
Phase 2 expansion at the facility.

October 2016 2 1239-651616.102

g:\projects\waste industries\high point\groundwater\wqmr\july 2016\final\final 2nd semi-annual 2016 wi-hp wqmr.docx
In addition to the groundwater monitoring points, the facility’s monitoring network includes four surface
water sampling points, SW-1 and SW-3, which are upstream from the waste area, and SW-2 and SW-4,
which are downstream monitoring points. These points are sampled in conjunction with the groundwater
monitoring wells in accordance with the facility’s permit.
Vinyl chloride and benzene were detected in the sample from downgradient monitoring well MW-2 at
concentrations above their respective Solid Waste Section Reporting Limits (SWSLs) and NC 2L Standards
during the July 2014 sampling event. On February 3, 2015, an Alternate Source Demonstration was
submitted in response to this detection that provided evidence that an unidentified source other than the
waste unit is likely responsible for the volatile organic compounds (VOCs) detected in the samples from
MW-2. On March 2, 2015, NC DEQ issued a response letter that allowed an additional six months to assess
potential sources of VOCs.
Benzene was detected in the sample from MW-2 at a concentration above the SWSL and NC 2L Standard
during the August 2015 sampling event and the facility transitioned to an Assessment Monitoring Program.
An Assessment Monitoring Notification and Work Plan (Work Plan) was submitted to the NC DEQ on
December 7, 2015, and was approved on January 28, 2016. The approved Work Plan stated that samples
from groundwater monitoring wells MW-1 and MW-2 would be analyzed for the NC Appendix II list of
constituents during the first semi-annual water quality monitoring event of 2016 and during subsequent
events, MW-1 and MW-2 would be analyzed for NC Appendix I list of constituents plus detected NC
Appendix II constituents.
The Work Plan requested that a new surface water point (SW-2A) be added to the monitoring well in lieu
of an additional groundwater monitoring well. The January 28, 2016, letter from the NC DEQ, stated that
additional information was needed before the request could be considered and directed that pore water
samples be collected during the first semi-annual water quality event of 2016. In a phone conversation in
June 2016 between representatives of the NC DEQ and Golder, pore water sampling was determined to
be acceptable to perform during the second semi-annual water quality monitoring event of 2016 pending
groundwater monitoring results from MW-2, which would determine if the facility would remain in
Assessment Monitoring.
1.3 Hydrogeologic Setting
Geologically, the facility is located within the Carolina Slate Belt of the Piedmont Physiographic Province of
North Carolina (NCGS, 1985). Generally, the Carolina Slate Belt consists of Late Proterozoic to Cambrian
volcanic and greenschist-facies metasedimentary rocks intruded by plutonic suites (Butler and Secor,
1991). The site geology is characterized by a regional-scale felsic intrusive complex, which consists mainly
of white to gray, fine- to coarse-grained, massive to foliated metamorphosed granitic rock. The region is
characterized by regional and small scale Mesozoic diabase dikes.

October 2016 3 1239-651616.102

g:\projects\waste industries\high point\groundwater\wqmr\july 2016\final\final 2nd semi-annual 2016 wi-hp wqmr.docx
The uppermost groundwater beneath the facility is present in a shallow, unconfined aquifer comprised of
saprolite, partially weathered rock (PWR), and granitic bedrock. Groundwater occurs at depths of
approximately 25 feet below grade along the northern upgradient side of the waste disposal area, and at a
depth of less than 10 feet below grade along the perimeter downgradient boundary. Depth to water
measurements, obtained during the July 2016 monitoring event and summarized in Table 1, were used to
prepare a groundwater surface contour map presented on Drawing 1.
Surface water and groundwater at the site generally flows south to southwest towards a tributary of Richland
Creek. Richland Creek is approximately 1300 feet south of the site and flows to the Deep River, which is
approximately 0.5 miles from the site. Groundwater beneath the site flows in three distinguishable and
vertically interconnected hydrogeologic units; saprolite, PWR, and bedrock. The groundwater surface
contour map and interpreted flow directions are consistent with previously submitted interpretations for this
facility.
Based on the July 14 - 15, 2016, groundwater surface contour map, the average hydraulic gradient in the
shallow aquifer underlying the site, as measured along the conceptual flow path shown on the contour map,
was calculated to be approximately 0.045 feet per foot. Groundwater velocities were calculated using a
hydraulic conductivity of 1.37E-05, which is the geometric mean of the hydraulic conductivities for each of
the hydrogeologic units present at the facility. The estimated effective porosity of the shallow aquifer is
expected to range from 0.20 (saprolite) to 0.09 (fractured rock). The effective porosity of the fractured rock
was used in calculations to provide a conservative estimate of groundwater flow.
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
7 feet/year, which is generally consistent with previous estimates (Table 3). The range of groundwater flow
is expected to vary depending on the hydrogeologic unit in which it occurs. 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, MONITROING RESULTS AND DISCUSSION
Field activities conducted for the July 2016 sampling event are discussed in the following sections.

October 2016 4 1239-651616.102

g:\projects\waste industries\high point\groundwater\wqmr\july 2016\final\final 2nd semi-annual 2016 wi-hp wqmr.docx
2.1 Visual Inspection Program
In order to ensure that a potential release is detected at the earliest possible time, the visual inspection
program is used by Golder personnel at the Waste Industries of High Point C&D Landfill. 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 July 2016 compliance monitoring event, no physical indicators
of a potential release were observed in the vicinity of the waste management areas.
2.2 Well Network and Groundwater Elevation Measurements
The current approved network of groundwater monitoring wells at the facility consists of eight monitoring
wells. Monitoring well construction information 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. Two upstream (SW-1 and SW-3) and two downstream (SW-2 and SW-4) surface water
monitoring points are also monitored and are shown on Drawing 1. At the request of the NC DEQ, three
pore water samples (PWS-1, PWS-2, and PWS-3) were monitored in the vicinity of MW-2 and are shown
on Drawing 1.
Monitoring well MW-1 is the facility’s background well and is located hydraulically upgradient of the waste
disposal area. Monitoring wells MW-2, MW-3, MW-4S, MW-5, MW-6, MW-7S, and MW-8 are located
downgradient of the waste disposal area and represent the facility’s downgradient compliance wells. The
well locations were selected to yield groundwater samples representative of the conditions in the uppermost
aquifer underlying the facility and monitor for potential releases from the landfill unit.
Depth-to-water measurements were 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 along with historical water level data.
As presented, the data 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 feet (plus
or minus). As expected, the range in fluctuation appears to be greater in the upgradient well MW-1, as this
well is located in a groundwater recharge area. The range in fluctuation in downgradient compliance wells,
which are located near groundwater discharge areas, is much less, presumably due to the stabilizing effect
of the hydraulic discharge boundary.

2.3 July 2016 Groundwater and Surface Water Monitoring Event
Personnel from Golder visited the facility on July 14-15, 2016, to purge and sample monitoring wells MW-1,
MW-2, MW-3, MW-4S, MW-5, MW-6, MW-7S, and MW-8 and to sample surface water monitoring points
SW-1, SW-2, SW-3, and SW-4. Pore water samples PWS-1, PWS-2, and PWS-3 were also collected
during the July 2016 monitoring event. Depth-to-water measurements were obtained from the network
monitoring wells and additional wells (MW-4D and MW-7D) to the nearest 0.01 foot using an electronic
water level indicator prior to purging the wells.
Monitoring wells were purged and sampled using low-flow sampling techniques from dedicated bladder
pumps. Measurements of temperature, pH, specific conductivity, dissolved oxygen (DO), oxidation-
reduction potential (ORP), and turbidity were recorded on approximately 3- to 5-minute intervals during the
purge, depending on the purge rate. In general, the purge rate was matched to the yield of the monitoring
well, as determined by continuously monitoring the depth-to-water, not allowing the purge rate to exceed
500 milliliters per minute. Purging was continued until stabilization was indicated by the field 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 bladder pump discharge lines into the labeled, laboratory-supplied,
pre-preserved sample containers after purging was completed based on stabilization of field parameters.
The surface water samples were collected directly from the stream flow, by lowering the sample containers
into the stream flow with the opening facing away from the current flow, taking care to prevent the over flow
of the sample containers and to minimize sample-induced turbidity. Measurements of temperature, pH,
specific conductivity, DO, ORP, and turbidity were recorded during the collection of the surface water
samples.
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 location, sampling method, field observations, and field measurements.
2.4 August 2016 Verification Groundwater Monitoring Event
Golder personnel visited the facility on August 4, 2016, to re-sample MW-2 and MW-6 for analysis of
benzene to verify the concentrations during the July 2016 event. The well was purged and sampled using
the same techniques as in July. After collection, the samples were placed in a cooler on ice, under chain-
of-custody control for analysis of benzene. The sampling logs are presented in Appendix A.

2.5 Laboratory Analysis Program
The July 2016 groundwater and surface water samples were shipped to Environmental Conservation
Laboratories, Inc. (ENCO) of Cary, NC under chain-of-custody control for analysis. As presented,
groundwater samples from MW-1, MW-2, MW-3, MW-4S, MW-5, MW-6, MW-7S, and MW-8 were analyzed
for the NC Appendix I list of constituents plus the C&D indicator parameters specific to 15A NCAC 13B
.544(a)(1)(D). There were no additional NC Appendix II ‘detects’ that MW-1 and MW-2 needed to be
analyzed for. The surface water samples at the facility were analyzed for the NC Appendix I list of
constituents. Groundwater and surface water samples were also analyzed for tetrahydrofuran, as required
in a memo issued by NC DEQ dated June 25, 2010. The pore water samples were analyzed for NC
Appendix I volatile organic compounds (VOCs), as instructed in the January 28, 2016, letter from the NC
DEQ. The samples were received at the laboratory on July 15, 2016, in good condition and properly
preserved.
2.6 July 2016 Sampling Results
Analytical results and field parameters for the July 2016 groundwater samples are summarized in Tables 4
and 5 with available historical data. Analytical results and field parameters for the July 2016 surface water
samples are summarized in Tables 6 and 7 with available historical data. The laboratory certificate-of-
analysis, chain-of-custody form and laboratory data review for the sampling event are included in Appendix
B.
As presented in Table 4, two NC Appendix I inorganic constituents were detected above their SWSLs in
samples from one or more downgradient compliance monitoring wells at the facility during the July 2016
monitoring event. Barium was detected above the SWSL in samples from downgradient wells MW-2,
MW-6, and MW-7S and cobalt was detected above the SWSL in the samples from MW-2 and MW-6.
Indicator parameters iron and manganese were detected above the SWSLs in samples from MW-2,
MW-4S, MW-5, MW-6, and MW-8. Alkalinity, chloride, and total dissolved solids (TDS) were detected
quantifiable concentrations in samples from each monitoring well and results are generally consistent with
historical data.
As presented in Table 4, two NC Appendix I organic constituents were detected above their SWSLs in
samples from one or more downgradient compliance monitoring wells at the facility during the July 2016
monitoring event. Benzene was detected above the SWSL in samples from MW-2 and MW-6. Toluene
was detected above the SWSL in the sample from MW-8 during this event.
As presented in Table 6, one NC Appendix I inorganic constituent (barium) was detected above the SWSL
in the sample from SW-2 during the February 2016 event. No other NC Appendix I inorganic or organic
constituents were detected at concentrations that exceeded the SWSLs during the event.

2.7 August 2016 Verification Sampling Results
The samples collected on August 4, 2016 from were analyzed for benzene. Benzene results for the
verification event were similar to the original concentrations and confirm the original detections.
3.0 LABORATORY AND FIELD QA/QC
A field blank was collected by Golder personnel as part of the July 2016 sampling event. ENCO analyzed
the field blank for the NC Appendix I list of constituents plus iron, manganese, and tetrahydrofuran. In
addition to the field blank, a laboratory-prepared trip blank accompanied the volatile sample containers to
and from the laboratory and was analyzed for NC Appendix I VOCs plus tetrahydrofuran. ENCO analyzed
the laboratory blanks for NC Appendix I constituents plus iron, manganese, and tetrahydrofuran. A review
of the laboratory data was performed by Golder personnel and is included in Appendix B.
There were five detections of NC Appendix I constituents in the field blank during the July 2016 event.
Nickel was detected in the field blank at a quantifiable concentration and barium, copper, iron, and
manganese were detected in the field blank at estimated concentrations. Based on data reviews performed
by Golder, the following concentrations are considered blank qualified: copper in samples MW-8, SW-2,
and SW-4; nickel in samples from MW-6, MW-7S, MW-8, SW-1, SW-2, and SW-4; iron in samples from
MW-3 and MW-7S; and manganese in samples from MW-1 and MW-7S.
4.0 DATA EVALUATION
4.1 North Carolina Groundwater and Surface Water Quality Standard
Comparisons
As presented in Table 4, cobalt was detected above the SWSL and Solid Waste Section Groundwater
Protection Standard (GPS) in the samples from MW-2 and MW-6. Cobalt was also detected below the
SWSL, but above the GPS, in the sample from MW-8. Thallium was detected below the SWSL, but above
the GPS in the samples from upgradient well MW-1 and downgradient wells MW-3, MW-4, MW-5, MW-7S,
and MW-8. Vanadium was detected below the SWSL, but above the GPS in the samples from MW-4S,
MW-6, and MW-7S. The estimated concentrations of cobalt and vanadium are similar to historical data and
are considered to be representative of natural conditions, and no further action is warranted. Many of the
concentrations of thallium are first time detections, but because they are below the SWSL, no further action
is warranted. Cobalt concentrations above the SWSL were statistically evaluated as described below and
were determined to be representative of background conditions.
The indicator parameters iron and manganese were detected in samples from downgradient wells MW-2,
MW-4S, MW-5, MW-6, and MW-8 at concentrations above their respective SWSLs and NC 2L Standards.
Because the concentrations in the downgradient wells are similar to concentrations in background data for

g:\projects\waste industries\high point\groundwater\wqmr\july 2016\final\final 2nd semi-annual 2016 wi-hp wqmr.docx
the facility, as described in the following section, the concentrations of iron and manganese are interpreted
to be naturally occurring and do not represent groundwater quality issues.
As presented, benzene was detected at or above the SWSL and NC 2L Standard in samples from MW-2
and MW-6. The concentrations of benzene were verified in a resampling event conducted on August 4,
2016. No other NC Appendix I VOCs were detected at concentrations above their respective groundwater
standard during the July 2016 event. As shown in Table 6, there were no concentrations of Appendix I
constituents that reported above applicable surface water standards during this event.
4.2 Statistical Evaluations
As discussed above, cobalt was detected in samples from downgradient wells MW-2 and MW-6 at
concentrations that exceeded the SWSL and GPS. Iron and manganese were detected in samples from
downgradient wells MW-2, MW-4S, MW-5, MW-6, and MW-8 at concentrations that exceeded their
respective SWSLs and NC 2L Standards. TDS was reported in the sample from MW-6 at a quantifiable
concentration that exceeded the NC 2L Standard. Therefore, the concentrations of cobalt, iron,
manganese, and TDS were statistically evaluated to determine if the reported concentrations exceeded
facility background concentrations.
The statistical worksheets and summary table are presented as Appendix C. Upon completion of statistical
analysis, the concentrations of cobalt, iron, manganese, and TDS were determined not to represent
statistically significant increases over background concentrations in the samples from downgradient wells
during the July 2016 event. The concentrations of cobalt, iron, manganese, and TDS are interpreted to be
naturally occurring and no further action is warranted. This is supported by data presented in the November
2003 United States (US) Environmental Protection Agency (EPA) document “Guidance for Developing
Ecological Soil Screening Levels,” which indicates that cobalt, iron, and manganese concentrations in NC
soils represent a substantial naturally occurring source in local soil that would account for the concentrations
detected in groundwater samples from MW-2 and MW-6.
This document presents mean soil metal background concentrations for each state, including NC, in
milligrams per kilogram (mg/kg). The mean concentration of cobalt in NC is 15 mg/kg (equivalent to 15,000
parts per billion [ppb]). The mean concentration of iron in NC is 37,053 mg/kg (equivalent to 37,053,000
parts per billion [ppb]). The mean concentration of manganese in NC is 563 mg/kg (equivalent to 563,000
parts per billion [ppb]). Each of these mean soil metal background concentrations would account for the
concentrations detected in groundwater samples from MW-2 and MW-6.

5.0 PORE WATER SAMPLING
As discussed in Section 1.2, pore water sampling was requested by the NC DEQ to evaluate if a new
surface water sample location downgradient of MW-2 can serve as an assessment monitoring location as
required by 15A NCAC 13B .0545(a)(1). On July 15, 2016, Golder personnel collected one upstream pore
water sample (PWS-1) and two downstream pore water samples (PWS-2 and PWS-3) in the portion of the
stream likely to receive groundwater from MW-2. The locations of the pore water samples are shown on
Drawing 1.
The samples were collected with an AMS Retract-A-Tip Sampler and a peristaltic pump. The sampler was
decontaminated prior to collecting each sample and new tubing was used at each sampling location. The
sampler was hammered into the subsurface in the stream bottom to refusal at depths that ranged from
approximately 1.5 feet below ground surface. The rods of the sampler were retracted approximately one
inch to expose a screen at the bottom of the sampler. Samples were collected from the hollow rods with
the peristaltic pump. The samples were analyzed for NC Appendix I VOCs.
As shown on the certificates-of-analysis in Appendix B, no NC Appendix I VOCs were detected above the
SWSLs in any of the pore water samples during the July 2016 event. Chloromethane was detected at an
estimated concentration, below the SWSL in the sample from PWS-3. Field parameters were used to
evaluate whether the pore water samples represent groundwater that is discharging to the stream. Table 8
compares field parameters from the pore water samples with groundwater samples from MW-2 and MW-8
and upstream surface water samples from SW-1 and SW-3. The data is shown graphically on Figure 1.
Data from MW-8 was used in the evaluation because it is located in close proximity to pore water sample
PWS-1.
Pore water measurements of specific conductivity, temperature, and DO are more similar to surface water
than groundwater. Pore water measurements of ORP appear to be distributed between the groundwater
and surface water measurements. Pore water measurements of pH are higher than groundwater and
surface water. Generally, specific conductivity of impacted groundwater is expected to be higher than
unimpacted groundwater. Therefore, specific conductivity measurements are expected to decrease
downgradient of the monitoring wells, which have had detections of VOCs. Based on these results, the
measurements from pore water samples are more similar to the surface water samples than the
groundwater samples, and there is limited evidence to support that the stream receives groundwater from
the MW-2 location. These results appear to be seasonal, as the February 2016 results supported that the
stream receives groundwater from the MW-2 location.
6.0 CONCLUSIONS
Benzene was reported at concentrations above the SWSLs and NC 2L Standards in samples from MW-2
and MW-6 during the July 2016 monitoring event. The facility will continue monitoring in accordance with

the requirements of the Assessment Monitoring Program as outlined in Title 15A NCAC 13B.0545. Due to
the reported concentration of benzene in the sample from MW-6, Waste Industries is submitting an
addendum to the Assessment Monitoring Notification and Work Plan submitted on December 7, 2015. The
next groundwater monitoring event is tentatively scheduled for January 2017.

2. GROUNDWATER SURFACE CONTOUR INTERVAL = 10 FEET
3. GROUNDWATER ELEVATIONS MEASURED ON JULY 14-15, 2016.
4. GROUNDWATER CONTOURS BASED ON LINEAR INTERPOLATION BETWEEN AND
EXTRAPOLATION FROM KNOWN DATA, TOPOGRAPHIC CONTOURS AND KNOWN FIELD
CONDITIONS. THEREFORE, GROUNDWATER CONTOURS MAY NOT REFLECT ACTUAL
CONDITIONS.
5. GROUNDWATER CONTOURS LINES SHOW THE WATER TABLE SHAPE AND ELEVATION.
THESE CONTOURS ARE INFERRED LINES FOLLOWING THE GROUNDWATER SURFACE AT A
CONSTANT ELEVATION ABOVE SEA LEVEL. THE GROUNDWATER FLOW DIRECTION IS
GENERALLY PERPENDICULAR TO THE GROUNDWATER SURFACE CONTOURS, SIMILAR TO
THE RELATIONSHIP BETWEEN SURFACE WATER FLOW AND TOPOGRAPHIC CONTOURS.
6. THE GROUNDWATER ELEVATIONS FOR MW-4D AND MW-7D WERE NOT USED IN THE
CONSTRUCTION OF GROUNDWATER CONTOURS.
