RE: WATER QUALITY MONITORING REPORT
FIRST 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 February 17 - 18, 2016, semi-annual
compliance monitoring event at the Waste Industries of High Point Construction and Demolition Landfill. This is the first Assessment Monitoring event for the facility.
During this 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 samples from upgradient well MW-1 and downgradient wells MW-4S, MW-5, and MW-8 at concentrations below the SWSL, but above the GPS. Vanadium was detected in samples
from downgradient wells MW-4S 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 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.
Toluene was detected for the first time in the sample from MW-8 above the SWSL, but well below the NC
2L Standard during the February 2016 event. Future concentrations will be monitored to determine the potential source of toluene. No other volatile organic compounds (VOCs) were detected at
concentrations above their respective SWSLs and groundwater standards during the event. No additional NC Appendix II constituents were detected at MW-1 or MW-2 during this event.
Copper, chromium, lead, nickel, and zinc were detected above their respective SWSLs and above the applicable surface water standards in downstream monitoring point SW-4 during the February 2016
event. The concentrations of inorganic concentrations in the sample from SW-4 are likely biased high by entrained sediment as evidenced by high turbidity, likely from an offsite source as there are no land
disturbance activities on the landfill property in the vicinity or upstream of SW-4. Heavy rains preceded

1.0 INTRODUCTION
This report summarizes the monitoring results from the February 17 - 18, 2016, 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.
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,

April 2016 2 1239-651616.101

g:\projects\waste industries\high point\groundwater\wqmr\february 2016\final\final 1st semi-annual 2016 wi-hp wqmr.docx
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 once again detected a 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.
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

g:\projects\waste industries\high point\groundwater\wqmr\february 2016\final\final 1st semi-annual 2016 wi-hp wqmr.docx
measurements, obtained during the February 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 February 17 - 18, 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 7.00 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 February 2016 sampling event are discussed in the following sections.

April 2016 4 1239-651616.101

g:\projects\waste industries\high point\groundwater\wqmr\february 2016\final\final 1st 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 February 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 February 2016 Groundwater and Surface Water Monitoring Event
Personnel from Golder visited the facility on February 17-18, 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. 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 Laboratory Analysis Program
The February 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 and MW-2 were analyzed for the NC Appendix II list of constituents
plus required indicator parameters specific to 15A NCAC 13B .544(a)(1)(D). Groundwater samples from
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. The surface water samples at the facility were analyzed

April 2016 6 1239-651616.101

g:\projects\waste industries\high point\groundwater\wqmr\february 2016\final\final 1st semi-annual 2016 wi-hp wqmr.docx
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 DENR 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 February 19,
2016, in good condition and properly preserved.
2.5 February 2016 Sampling Results
Analytical results and field parameters for the February 2016 groundwater samples are summarized in
Tables 4 and 5 with available historical data. Analytical results and field parameters for the February
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, 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 February
2016 monitoring event. Barium was detected above the SWSL in samples from downgradient wells
MW-2, MW-6, and MW-7S. Cobalt was detected above the SWSL in the samples from MW-2 and MW-6.
Zinc was detected above the SWSL in the sample from MW-4S.
Indicator parameters iron and manganese were detected above the SWSLs in samples from MW-2,
MW-4S, MW-5, MW-6, and MW-8. Total dissolved solids (TDS) and alkalinity were detected at all of the
monitoring locations and results are generally consistent with historical data. Toluene was detected
above the SWSL in the sample from MW-8 for the first time during this event. No other VOCs were
detected at quantifiable concentrations above the SWSLs in samples from groundwater monitoring wells
during the February 2016 monitoring event.
As presented in Table 6, five NC Appendix I inorganic constituents were detected above their respective
SWSLs in samples from surface water monitoring locations during the February 2016 event. Chromium,
vanadium, and zinc were detected at quantifiable concentrations above their respective SWSLs in the
sample from upstream monitoring point SW-3. Zinc was also detected at quantifiable concentrations
above the SWSL in the samples from upstream point SW-1 and downstream point SW-2. Barium, cobalt,
copper, chromium, nickel, vanadium, and zinc were detected at quantifiable concentrations above their
respective SWSLs in the sample from downstream monitoring point SW-4. Antimony, beryllium, and lead
were detected at estimated concentrations (due to dilution) above their respective SWSLs in the sample
from SW-4. The inorganic detections in the sample from SW-4 are due to a high sediment load in the
stream from an off-site source. No NC Appendix I VOCs were detected at quantifiable concentrations
above the SWSLs in samples from surface water monitoring locations during the February 2016
monitoring event.

3.0 LABORATORY AND FIELD QA/QC
A field blank was collected by Golder personnel as part of the February 2016 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 and the trip blank for NC Appendix I volatile organic compounds and
tetrahydrofuran. A review of the laboratory data was performed by Golder personnel and is included in
Appendix B.
There were two detections of NC Appendix I constituents in the field blank during the February 2016
event. Copper 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-1, SW-2, and SW-3, and manganese in sample 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 samples from upgradient well MW-1 and downgradient wells MW-4S,
MW-5, and MW-8. Vanadium was detected below the SWSL, but above the NC 2L Standard, 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.
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 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, no
NC Appendix I VOCs were detected at concentrations above their respective groundwater standard
during the February 2016 event.
As shown in Table 6, copper, chromium, nickel, and zinc were detected at quantifiable concentrations
above their respective SWSLs and applicable surface water standards in downstream surface water
monitoring point SW-4. Lead was detected at an estimated concentration (due to a dilution) above the
SWSL and applicable surface water standard. The elevated metal concentrations in the sample from

April 2016 8 1239-651616.101

g:\projects\waste industries\high point\groundwater\wqmr\february 2016\final\final 1st semi-annual 2016 wi-hp wqmr.docx
SW-4 are biased high by entrained sediment as evidenced by high turbidity values. There are no landfill
or other land disturbance activities on the landfill property in the vicinity of SW-4. An offsite source from
an adjacent property coupled with heavy rains preceding the event is likely the source of the high
sediment load in the stream. Future results will be monitored to determine trends for metals
concentrations.
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 February 2016 event. The concentrations of cobalt, iron, manganese, and
TDS are interpreted to be naturally occurring and no further action is warranted.
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 February 28, 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 0.7 to 0.8 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 sampler’s rods with the peristaltic pump.
The samples were analyzed for NC Appendix I VOCs and no VOCs were detected in the samples. Field
parameters were used to evaluate whether the pore water samples represent groundwater that is

g:\projects\waste industries\high point\groundwater\wqmr\february 2016\final\final 1st semi-annual 2016 wi-hp wqmr.docx
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.
The results indicate that there is generally a greater range in values for the pore water samples than the
groundwater and surface water samples, with the only exception being specific conductivity where
groundwater has more variability. Pore water measurements of pH and ORP are more similar to
groundwater measurements than surface water. Temperature and DO measurements appear to be
distributed between the groundwater and surface water measurements. Shallow subsurface water (pore
water) measurements of temperature and DO are expected to be impacted by surface water, given that
there is a difference in parameter measurements between groundwater and surface water. Also, the
transfer of heat between shallow groundwater and the much cooler surface water is expected. Pore
water measurements of specific conductivity are more similar to surface water than groundwater.
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, there is sufficient
evidence to support that the stream receives groundwater from the MW-2 location and a surface water
monitoring location can serve as a new monitoring location.
6.0 CONCLUSIONS
No NC Appendix I organic compounds were reported at concentrations above the SWSLs and NC 2L
Standards during the February 2016 monitoring event. The inorganic concentrations in the sample from
SW-4 are biased high by entrained sediment as evidenced by high turbidity due to a high sediment load in
the stream, likely from an offsite source coupled with heavy rains preceding the event. Pore water
sampling results indicate that there is sufficient evidence that groundwater from the MW-2 area
discharges to the downgradient stream. Therefore, Golder recommends that a new surface water
location (SW-42A) be utilized as a groundwater assessment monitoring location during future Assessment
Monitoring events. The next groundwater monitoring event is tentatively scheduled for July 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.

 The 8270D continuing calibration verification sample (CCV) exhibited a high bias for
Isodrin; however this analyte was not detected in the associated samples, reducing the
impact of the deviation. The CCV showed a low bias for 1,4-Phenylenediamine, 1-Napthylamine, and 4-Aminobiphenyl; the reported results should be considered
minimum estimates.
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 8151 Surrogate spike recovery of 2,4-DECAA was outside of control limits for the MS
and MSD samples.
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 recoveries of Iron, Manganese, and Mercury were outside of control limits for
the 6010C MS, MSD, and or Post Spike samples (method 7470A for Mercury). The QC
batches were approved based on acceptable LCS recovery of these elements.

 The spike recoveries of Alkalinity and Sulfide were outside of control limits for the MS
and or MSD samples. The QC batches were approved based on acceptable LCS recovery
of these analytes.
 The spike recovery of 1,1Dichloroethene was outside of control limits for the 8260B MS
and MSD samples. The qc batch was approved based on acceptable LCS recovery.

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.

 Field Blank
o Copper @ 3.66 ug/L (J)
-Add B flags MW-8, SW-1, SW-2, SW-3
o Manganese @ 1.19 ug/L (J)
-Add B flags to MW-7s @ 2.26 ug/L (J)
TM It is clear from the laboratory report that samples have or have not been diluted during
analysis, and if the samples have been diluted, the result is reported as a multiple of
the dilution (e.g., a sample diluted 10x resulting in an analytical detection of 1.0 should be reported as 10). Those that have been diluted are listed below with the dilution
factor.

 Sulfate as SO4
o MW-1 DF = 2x
o MW-6 DF = 2x

 Chloride
o MW-2 DF= 2x
o MW-6 DF= 2x

 Total Alkalinity as CaCO3
o MW-2 DF = 6x
o MW-6 DF = 3x
o MW-8 DF = 2x

 Due to high levels of non-target analytes, sample SW-4 was processed at a dilution for the
6010C and 6020 A metals, resulting in elevated reporting limits. Selenium is reported by
both 6010C and 6020 to confirm compliance with the NC Solid Waste Section Limit for this
element. Sediment (a layer approximately 3-5 mm thick) was observed in the Metals
container.
