RE: WATER QUALITY MONITORING REPORT
FIRST SEMI-ANNUAL 2017 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 January 11 - 12, 2017, semi-annual
compliance monitoring event at the Waste Industries of High Point Construction and Demolition Landfill. Assessment monitoring wells AMW-1 and AMW-2, which were installed in December 2016, were sampled
for the first time during this event due to recent benzene exceedances in samples from MW-2 and MW-6
Arsenic and barium were detected during the event in the sample from downgradient monitoring well MW-2
at concentrations greater than their respective Solid Waste Section Reporting Limits (SWSLs) and NC 2L Standards. The arsenic and barium concentrations were statistically evaluated and determined to be
statistically significant when compared to background concentrations. Dissolved arsenic and barium were analyzed for the sample from MW-2 and were reported at concentrations below their respective NC 2L
Standards and statistically calculated background concentrations. Although the field turbidity values were relatively low for the sample from MW-2, fine-grained sediment could be biasing metals concentrations
high. Based on published soil and stream sediment metals data for Guilford County and North Carolina, the arsenic and barium concentrations in the sample from MW-2 were visually compared to and are within
natural background concentrations. Therefore, no further action is recommended at this time.
Cobalt was detected in the samples from downgradient wells MW-2 and MW-6 at concentrations that
exceeded the 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 not determined to represent statistically significant increases over background concentrations. Publically available data support that cobalt is naturally occurring. Therefore, no further action is warranted.
Cobalt was also detected at estimated concentrations below the SWSL, but above the GPS, in samples from MW-5, MW-8, AMW-1, and AMW-2. Vanadium was detected in samples from downgradient wells
MW-4S and MW-7S at estimated 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.
The indicator parameter iron was detected at concentrations above the SWSL and NC 2L Standard in
samples from MW-2, MW-4S, MW-5, MW-6, MW-8, AMW-1, and AMW-2. The indicator parameter manganese was detected at concentrations above the SWSL and NC 2L Standard in samples from MW-2,
MW-5, MW-6, MW-8, AMW-1, and AMW-2. Total dissolved solids (TDS) was detected above the SWSL and NC 2L Standard in the samples from MW-2 and MW-6. Concentrations of indicator parameters are
generally consistent with historical data, where present. The iron, manganese, and TDS concentrations were statistically compared to background concentrations and the concentrations of TDS in the sample
from MW-2 and manganese in the samples from MW-8, AMW-1, and AMW-2 were determined to represent statistically significant increases (SSIs) over background. There were insufficient background data to

1.0 INTRODUCTION
This report summarizes the monitoring results from the January 11 - 12, 2017, groundwater and surface
water sampling and analysis 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. Two assessment monitoring wells, AMW-1 and AMW-2, were installed
in December 2016 and were sampled for the first time during the January 2017 monitoring event.

April 2017 2 1239-651617.101

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. No additional NC Appendix II constituents were detected in the samples from
MW-1 and MW-2 during the February 2016 event and therefore, future events will be analyzed for the NC
Appendix I list of constituents.
Benzene was detected in the sample from MW-6 at a concentration above the SWSL and NC 2L Standard
during the July 2017 sampling event. Based on the July 2017 monitoring results, an Assessment Monitoring
Notification and Work Plan Addendum (Addendum) was submitted to the NC DEQ on October 21, 2016,
and was approved on October 31, 2016. The approved Addendum stated that assessment monitoring
wells, AMW-1 and AMW-2, would be installed downgradient of MW-2 and MW-6, respectively. The
Addendum also stated that samples from groundwater monitoring wells MW-6, AMW-1, and AMW-2 would
be analyzed for the NC Appendix II list of constituents during the first semi-annual water quality monitoring
event of 2017 and during subsequent events, MW-6, AMW-1, and AMW-2 would be analyzed for NC
Appendix I list of constituents plus detected NC Appendix II constituents. Assessment monitoring wells
AMW-1 and AMW-2 were installed in December 2016 in accordance with the Addendum and sampled for
the first time during the January 2017 event.

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.
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 January 2017 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 January 11, 2017, groundwater surface contour map, the average hydraulic gradient in the
shallow aquifer underlying the site, as measured along the conceptual flow path shown on the contour map,
was calculated to be approximately 0.043 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.

April 2017 4 1239-651617.101

The average estimated linear groundwater flow velocity under the waste management unit is approximately
6.7 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 January 2017 sampling event are discussed in the following sections.
2.1 Visual Inspection Program
In order to ensure that a potential release is detected at the earliest possible time, the visual inspection
program is used 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 January 2017 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 compliance
monitoring wells and two assessment 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.
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, MW-8, AMW-1, and AMW-2,
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.

April 2017 6 1239-651617.101

2.3 January 2017 Groundwater and Surface Water Monitoring Event
Personnel from Golder visited the facility on January 11-12, 2017, to purge and sample monitoring wells
MW-1, MW-2, MW-3, MW-4S, MW-5, MW-6, MW-7S, MW-8, AMW-1, and AMW-2, and to sample surface
water monitoring points SW-1, SW-2, SW-3, and SW-4. Depth-to-water measurements were obtained from
the network monitoring wells and additional wells (MW-4D, AMW-1, and AMW-2) to the nearest 0.01 foot
using an electronic water level indicator prior to purging the wells.
Compliance monitoring wells were purged and sampled using low-flow sampling techniques from dedicated
bladder pumps. Assessment monitoring wells were purged and sampled using low-flow sampling
techniques from portable 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 Laboratory Analysis Program
The January 2017 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-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). Groundwater samples from MW-6, AMW-1, and AMW-2 were analyzed for the NC Appendix

April 2017 7 1239-651617.101

II list of constituents plus the C&D indicator parameters listed in 15A NCAC 13B .544(a)(1)(D). 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 samples were received at the laboratory on January 13, 2017, in good condition
and properly preserved.
2.5 January 2017 Sampling Results
Analytical results and field parameters for the January 2017 groundwater samples are summarized in
Tables 4 and 5 with available historical data. Analytical results and field parameters for the January 2017
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, three 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 January 2017
monitoring event. Arsenic was detected above the SWSL from downgradient well MW-2. Barium was
detected above the SWSL in samples from downgradient wells MW-2, MW-6, MW-7S, AMW-1 and AMW-2.
Cobalt was detected above the SWSL in the samples from MW-2 and MW-6.
Indicator parameter iron was detected above the SWSL in samples from MW-2, MW-4S, MW-5, MW-6,
MW-8, AMW-1, and AMW-2. Indicator parameter manganese was detected above the SWSL in the
samples from MW-2, MW-5, MW-6, MW-8, AMW-1, and AMW-2. Alkalinity, chloride, and total dissolved
solids (TDS) were detected at quantifiable concentrations in samples from one or more monitoring wells
and results are generally consistent with historical data.
As presented in Table 4, no NC Appendix I organic constituents were detected above their SWSLs during
the January 2017 monitoring event. No NC Appendix II constituents were detected in the samples from
MW-6, AMW-1, and AMW-2.
As presented in Table 6, one NC Appendix I inorganic constituent was detected above the SWSL in one or
more surface water samples during the January 2017 event. Zinc was detected at a concentration that
exceeded the SWSL in the sample from upstream monitoring point SW-1 and downstream monitoring point
SW-4. No other NC Appendix I inorganic or organic constituents were detected at concentrations that
exceeded the SWSLs during the event in surface water points.

April 2017 8 1239-651617.101

3.0 LABORATORY AND FIELD QA/QC
A field blank was collected by Golder personnel as part of the January 2017 sampling event. ENCO
analyzed the field blank for the NC Appendix II 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 II VOCs plus
tetrahydrofuran. ENCO analyzed the laboratory blanks for NC Appendix II constituents plus iron,
manganese, and tetrahydrofuran. A review of the laboratory data was performed by Golder personnel and
is included in Appendix B.
Copper was detected at an estimated concentration in the field blank during the January 2017 event.
Acetone and methylene chloride were detected at estimated concentrations in laboratory method blanks
during the event. Based on data reviews performed by Golder, the concentrations of copper in samples
MW-1, MW-2, MW-3, MW-4S, MW-5, MW-6, MW-7S, MW-8, AMW-1, AMW-2, SW-1, SW-2, SW-3, and
SW-4 are considered blank-qualified.

April 2017 9 1239-651617.101

4.0 DATA EVALUATION
4.1 North Carolina Groundwater and Surface Water Quality Standard
Comparisons
As presented in Table 4, two NC Appendix I inorganic constituents were detected above their respective
SWSL and NC 2L Standard in one or more groundwater monitoring wells during the January 2017 event.
Arsenic and benzene were detected above their respective SWSLs and NC 2L Standards in the sample
from downgradient well MW-2. Dissolved arsenic and barium were analyzed for the sample from MW-2
and the concentrations of both constituents were determined to be below their respective NC 2L Standards.
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 samples from, MW-5, MW-8, AMW-1, and AMW-2. Vanadium was detected below the SWSL, but
above the GPS in the samples from MW-4S and MW-7S. The 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. Cobalt concentrations above the SWSL were statistically evaluated, as described below, and
were determined to be representative of background conditions.
The indicator parameter iron was detected above the SWSL and NC 2L Standard in samples from MW-2,
MW-4S, MW-5, MW-6, MW-8, AMW-1, and AMW-2. The indicator parameter manganese was detected
above the SWSL and NC 2L Standard in the samples from MW-2, MW-5, MW-6, MW-8, AMW-1, and
AMW-2. TDS was detected above the SWSL and NC 2L Standard in the samples from MW-2 and MW-6.
Because the concentrations of iron and manganese in the samples from downgradient wells are similar to
concentrations in background data for 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. No NC Appendix I VOCs were detected at concentrations above their respective groundwater
standard during the January 2017 event.
As shown in Table 6, zinc was reported above the Freshwater Acute and Chronic standards from upstream
monitoring point SW-1 during the January 2017 event. Because the exceedance was in an upstream
sample, the exceedance is not related to landfill activities from the facility and no further action is warranted.
No other NC Appendix I constituents were reported above applicable surface water standards during the
event.
4.2 Statistical Evaluations
As discussed above, arsenic and barium were detected in the sample from downgradient well MW-2 at
concentrations that exceeded their respective SWSL and NC 2L Standard. Cobalt was detected in samples
from downgradient wells MW-2 and MW-6 at concentrations that exceeded the SWSL and GPS. Indicator
parameter iron was detected above the SWSL and NC 2L Standard in samples from MW-2, MW-4S, MW-5,

April 2017 10 1239-651617.101

MW-6, MW-8, AMW-1, and AMW-2. Indicator parameter manganese was detected above the SWSL and
NC 2L Standard in the samples from MW-2, MW-5, MW-6, MW-8, AMW-1, and AMW-2. TDS was detected
above the SWSL and NC 2L Standard in the samples from MW-2 and MW-6. Therefore, the concentrations
of arsenic, barium, 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 in the samples from MW-2 and MW-6, iron in samples from MW-2,
MW-4S, MW-5, MW-6, MW-8, AMW-1, and AMW-2, manganese in samples from MW-2, MW-5, and MW-6,
and TDS in the sample from MW-6 were determined to not represent statistically significant increases
(SSIs) over background concentrations during the January 2017 event. These concentrations are
interpreted to be naturally occurring and no further action is warranted.
The concentrations of arsenic, barium, and TDS in the sample from MW-2 and manganese in the samples
from MW-8, AMW-1, and AMW-2 were determined to represent SSIs over background. Dissolved arsenic
and barium were analyzed for the sample from MW-2 and the concentrations of both constituents were
determined to be below their respective statistically calculated background concentrations. Therefore, the
concentrations of arsenic, barium, and TDS in the sample from MW-2 are interpreted as being biased high
by fine-grained entrained sediment in the sample and do not represent a water quality issue. Field turbidity
values were relatively low; therefore, no re-development is recommended at this time.
There were insufficient background data to perform intra-well statistics on the concentrations of manganese
from the newly installed monitoring wells AMW-1 and AMW-2. The concentrations of manganese in the
samples from MW-8, AMW-1, and AMW-2 are similar to background concentrations from other facility
downgradient wells and likely represent natural occurring conditions.
4.3 Evaluation of Arsenic, Barium, Cobalt, and Manganese Concentrations
A literature search of arsenic, barium, cobalt, and manganese concentrations in soils and stream sediment
for NC and Guilford County, NC, specifically, was conducted to provide additional evidence that the source
of arsenic, barium, cobalt, and manganese in samples are naturally occurring. Data presented in the
November 2003 United States (US) Environmental Protection Agency (EPA) document “Guidance for
Developing Ecological Soil Screening Levels” indicate that arsenic, barium, cobalt, and manganese
concentrations in NC soils represent a substantial naturally occurring source in local soil that would account
for the concentrations detected in the groundwater samples. This document presents mean soil metal
background concentrations for each state, including NC, in milligrams per kilogram (mg/kg). The mean
concentration of arsenic in NC is 4.8 mg/kg (equivalent to 4,800 parts per billion [ppb]), which would account
for the concentrations detected in the groundwater sample MW-2. The mean concentration of barium in
NC is 356 mg/kg (equivalent to 356,000 ppb), which would account for the concentration detected in the

April 2017 11 1239-651617.101

groundwater sample MW-2. The mean concentration of cobalt in NC is 15 mg/kg (equivalent to 15,000
ppb), which would account for the concentrations detected in the groundwater samples MW-2 and MW-6.
The mean concentration of manganese in NC is 563 mg/kg (equivalent to 563,000 ppb), which would
account for the concentrations detected in the groundwater samples from MW-8, AMW-1, and AMW-2.
Table 2.3 for the “Guidance for Developing Ecological Soil Screening Levels” is provided in Appendix D.
The United States Geological Survey (USGS) National Geochemical Survey Database is a collection of
stream sediment data from across the US. This database was used to locate 14 stream sediment samples
collected between 1 to 20 miles from the Waste Industries of High Point C&D Landfill. Arsenic
concentrations from the nearby stream sediment samples ranged from non-detect to 12 parts per million
(ppm) (equivalent to non-detect to 12,000 ppb), with a mean concentration of 2 ppm (equivalent to 2,000
ppb). These concentrations of arsenic in sediment would account for the concentrations detected in the
groundwater sample from MW-2. Barium concentrations from the nearby stream sediment samples ranged
from 104 to 2,630 ppm (equivalent to 104,000 to 2,630,000 ppb), with a mean concentration of 544 ppm
(equivalent to 544,000 ppb). These concentrations of barium in sediment would account for the
concentrations detected in the groundwater sample from MW-2. Cobalt concentrations from the nearby
stream sediment samples ranged from non-detect to 24 ppm (equivalent to non-detect to 24,000 ppb), with
a mean concentration of 11 ppm (equivalent to 11,000 ppb). These concentrations of cobalt in sediment
would account for the concentrations detected in the groundwater samples from MW-2 and MW-6.
Manganese concentrations from the nearby stream sediment samples ranged from 175 to 1,790 ppm
(equivalent to 175,000 to 1,790,000 ppb), with a mean concentration of 892 ppm (equivalent to 892,000
ppb). These concentrations of manganese in sediment would account for the concentrations detected in
the groundwater sample from MW-8, AMW-1, and AMW-2. A summary table of the data used from the
National Geochemical Survey Database is provided in Appendix D.
Summary tables from each of the above-referenced geochemical studies are included in Appendix D for
reference. Based on the soil and stream sediment metals data presented above, the arsenic, barium,
cobalt, and manganese concentrations reported in the groundwater samples are within natural background
concentrations. Therefore, future arsenic, barium, cobalt, manganese results will continue to be monitored,
and no further action is warranted at this time.

5.0 CONCLUSIONS
No VOCs were detected above the SWSLs and applicable groundwater standards during the January 2017
event. The facility will continue monitoring in accordance with the requirements of the Assessment
Monitoring Program as outlined in Title 15A NCAC 13B.0545, the Work Plan, and Addendum. If benzene
is reported below the NC 2L Standard in the samples from MW-2 and MW-6 for a second consecutive
event, the facility will revert to Detection Monitoring Program as outlined in Title 15A NCAC
13B.0545(b)(9)(A). The next groundwater monitoring event is tentatively scheduled for June 2017.

2.0 SAMPLE HOLDING TIMES
WB Holding times for extraction and/or analysis were met for each analytical
Method (see below for reference).

Review Criteria
Method Analytes Holding Time
SM 2540C-1997 TDS
EPA Method 300 Chloride, Sulfate as SO4
EPA Method 8260B Benzene,
Tetrahydrofuran

EPA Method 310.2 Total Alkalinity as
CaCO3

EPA Method 6010D As, Ba, Cu, Fe, Mn, Co,
Ag, V, Ni Total

EPA Method 6020B Antimony, Total

3.0 LABORATORY QUALITY CONTROL REVIEW WB Laboratory analyzed at least one internal blank for each method, where applicable.

WB Laboratory blank is interference-free.
 Acetone and Methylene Chloride were detected in the 8260B Method Blanks; however,
these analytes were not detected in the associated samples, reducing the impact of the
deviations.
 Acetone @ 11 ug/L
 Methylene Chloride @ 0.57 ug/L
WB Surrogate recoveries are provided for each analytical method, where applicable.

WB Surrogate recoveries for each method are within the acceptable limits (i.e., at least 50% of the surrogates were within range).
 The surrogate spike recovery of 2,4,5,6-TCMX was outside of control limits for the 8081B
MSD sample and the 8082A LCS, MW-6 and Field Blank samples.
 The surrogate spike recovery of 2,4,5,6-TCMX was outside of control limits for the 8081B
MSD sample and the 8082 A LCS, AMW-1, and AMW-2 samples. The samples were
approved based on acceptable recovery of the other surrogate standard.
 The 8270D CCV exhibited a high bias for 2-Acetoaminofluroene and Famphur; however,
these analytes were not detected in
the associated samples, reducing the impact of the deviation. The CCV showed a low
bias for 1,4-Phenylenediamine, 1-Naphthylamine, 2-Naphthylamine, and 4-
Aminobiphenyl. The reported results should be considered minimum estimates.
WB MS/MSD/LCS data results are provided for each analytical method.
WB 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 recoveries of Iron, Manganese, and Mercury were outside of control limits for
the MS, MSD, and or Post Spike samples. The QC batches were approved based on
acceptable LCS recovery of these elements.
 The spike recoveries of Alkalinity and Chloride were outside of control limits for the MS
(Chloride) or MSD (Alkalinity) samples. The QC batches were approved based on
acceptable LCS recovery of these analytes.
 Precision between duplicate spikes of the 8081B analytes exceeded acceptance
criteria; however, the individual recoveries were within control limits. The QC
batch was approved based on acceptable LCS recovery of these analytes and
completeness of the QC data. The Continuing Calibration Verification sample
(CCV) exhibited a high bias for Endrin; however, this analyte was not detected in
the associated samples, reducing the impact of the deviation.

4.0 ANALYTE LISTS/METHODS
WB The proper number of constituents are present for each analyte list as identified above (including detects where applicable).

WB Proper EPA SM 2540C-1997 analytical methods were used for analysis.

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

WB Trip, field and/or equipment, and laboratory blank results have all been reported. All detects for blanks are listed below by constituent. All laboratory method blanks, if any,
have been ‘flagged’ with a ‘B’ where detected in other samples as appropriate and a
laboratory narrative was provided. If the sample was flagged by the laboratory and is
not within 5X of the concentration in the blank (or 10X for commonly detected laboratory contaminants-acetone, methylene chloride and phthalates), list below with
explanation if flags should be removed. If flags need to be added for samples, also
list below.
