ALAMANCE COUNTY, NORTH CAROLINA
1.0 INTRODUCTION
Buxton Environmental, Inc. (BEI) respectfully submits the methods and results of the first semi-annual 2021
groundwater, surface water and leachate monitoring, and even year 1,4-dioxane (SIM) monitoring schedule
activities conducted at the Alamance County -Austin Quarter Landfill (Permit No.: 0104) located at 2701 Austin
Quarter Road near Saxapahaw in Alamance County, North Carolina. These activities were conducted to
monitor water quality and hydrogeologic characteristics at the lined Subtitle D municipal solid waste (MSW)
landfill, and the temporarily closed unlined construction and demolition (C&D) landfill. Site location and site
layout maps are provided in Figures 1 and 2, respectively.
The monitoring activities were conducted in general accordance with current North Carolina Department of
Environmental Quality, Division of Waste Management -Solid Waste Section (NCSWS) Detection Monitoring
Program Rules for lined MSW landfills (15A NCAC 13B .1632 and .1633); NCSWS Detection Monitoring
Rules (15A NCAC 13B .0544) and Assessment and Corrective Action Rules (15A NCAC 13B .0545) for C&D
landfills; the NCSWS letter dated August 8, 2016 requesting Assessment Monitoring or an Alternate Source
Demonstration be conducted for Appendix I inorganic constituent (metals) exceedances above North Carolina
Groundwater Protection Standards (NCGPSs) for lined MSW landfills; the NCSWS letter dated September 9,
2016 concerning 14-day notification following a groundwater constituent exceedance of NCGPSs for the first-
time; a March 23, 2017 memorandum from the NCSWS concerning routine up -keep and maintenance issues at
monitoring wells; and a May 29, 2018 memorandum from the NCSWS requiring the analysis of 1,4-dioxane by
EPA Method 8260 (VOCs) or EPA Method 8270 (semi-VOCs) utilizing the select ion monitoring (SIM)
procedure, the discontinuation of Solid Waste Section Limits (SWSLs, minimum laboratory detection limits)
and opting for EPA approved analytical methods sufficiently sensitive to quantify the presence of constituents
at or below applicable standards. According to NCSWS rules dated April 1, 2011, the statistical evaluation of
historical groundwater data at municipal solid waste landfills is now optional and statistically significant
increases in target constituents no longer warrant additional assessment.
The NCGPSs are generally defined by the NCSWS as the most protective of the Federal Maximum
Contaminant Level for Drinking Water (MCL), the North Carolina 2L Groundwater Quality Standards (2L
NCGQSs), or NCGPSs established by the NCSWS (generally obtained from interim established 2L NCGQSs).
The NCGPS and 2L NCGQS for a non -naturally occurring constituent with no established standard is the
practical quantitation limit (PQL). For naturally occurring constituents (i.e. metals), the NCGPS and the 2L
NCGQS are the naturally occurring background concentrations. For clarity purposes, the NCGPSs and 2L
NCGQSs are essentially synonymous with each other. According to the NCGPSs and 2L NCGQSs, non -
quantified J-flagged laboratory data (estimated qualified data) which are detected less than the quantifiable
PQL, limit of quantitation (LOQ) or reporting limit (RL) (all synonyms) and above the method detection limit
(MDL) (lowest non -quantified limits of the laboratory instrumentation) are not considered exceedances of
NCGPSs or 2L NCGQSs. The NCGPSs in this report have been updated to reflect current standards issued by
the NCSWS on October 15, 2018.
A summary of background information, and the methods, results, conclusions and recommendations of this
investigation is outlined below.

2.0 RECENT BACKGROUND INFORMATION
A summary of historical background information for the Alamance County — Austin Quarter Landfill is
provided in Appendix A. Any future substantial changes, additions or modifications to the historical
background information section will be highlighted with bold type.
On February 25, 2019, Buxton Environmental, Inc., on behalf of Alamance County, submitted an emailed
request to Mr. Perry Sugg, P.G. (site project manager) with the NCSWS to alter the Appendix II groundwater
sampling schedule at the C&D landfill following completion on the four (4) background Appendix II sampling
events, which deviates from a November 29, 2017 letter from Mr. Ervin Lane (former NCSWS site manager for
Alamance County landfills). The November 29, 2017 letter from the NCSWS indicated that following
completion of the four (4) background Appendix II monitoring events at downgradient compliance wells MW-
5, MW-5R, MW-6, and upgradient background well MW-7, annual full list Appendix II sampling should be
conducted at monitor wells indicating 2L NCGQS exceedances along with Appendix I VOCs (plus
tetrahydrofuran and 1,4-dioxane), Appendix I metals and additional C&D parameters should be conducted
during the first semi-annual event per year; and that historically detected well specific Appendix II parameter
sampling along with the remaining Appendix I (plus) analytical requirements for C&D landfills should be
conducted during the second semi-annual event per year. During a December 1, 2018 clarification
conversation, Mr. Lane agreed that a revised Appendix II sampling schedule could be requested following
completion of the four (4) background monitoring events. Based on the findings of the background Appendix II
sampling at the C&D landfill, no additional Appendix II parameters (other than several sulfide and cyanide hits,
which are also naturally occurring) were detected above 2L NCGQSs or NCGPSs in the four groundwater
monitor wells. The newly proposed sampling schedule for the C&D landfill is provided below, as originally
presented in Section 8.0 (Recommendations) of the December 4, 2018 Second Semi -Annual 2018 report
prepared by Buxton Environmental, Inc:
• Semi-annual Appendix I Detection Monitoring (VOCs (plus tetrahydrofuran and 1,4-dioxane by EPA
Method 8260B (SIM)), metals (plus mercury) and additional C&D parameters) will be conducted at the
C&D landfill.
• Biennial Appendix II Assessment Monitoring (full Appendix II list, along with the remaining analytical
requirements for C&D landfills) will be conducted once every 2 years at the C&D landfill. The next
Appendix II Assessment Monitoring event is scheduled to be conducted in October 2022.
• A more refined well specific sampling frequency and parameters list, along with necessary Assessment
Monitoring activities, will be determined following future groundwater monitoring events at the C&D
landfill.
On February 26, 2019, Mr. Perry Sugg, P.G. with the NCSWS approved the above requested sampling schedule
for the C&D landfill.
During the second semi-annual 2020 monitoring event conducted on October 5, 2020, no Appendix II specific
constituents were detected above NCGPSs at groundwater samples collected from monitor wells MW-5, MW-
5R, MW-6 or MW-7, other than the sulfide detected at background monitor well MW-7 (which appears to be
naturally occurring).
On March 2, 2020, Mr. Ervin Lane with the NCSWS indicated that a new policy would allow permitted
landfills to discontinue/reduce the required analysis of 1,4-dioxane (by EPA SIM) during routine monitoring at
compliance groundwater monitor wells and surface water sample locations, if they have been below the MDL

for two (2) consecutive events. Lined MSW facilities, with or without detections of 1,4-dioxane (SIM) in the
leachate, would also be allowed the same discontinuation of the 1,4-dioxane (SIM) analysis requirement.
However, leachate samples at lined MSW facilities are required to continue to be analyzed for 1,4-dioxane
(SIM) on a semi-annual basis.
Based on this new policy, Mr. Ross Klingman, P.G. with BEI submitted an email request to Mr. Perry Sugg,
P.G. with the NCSWS on March 2, 2020 requesting that routine semi-annual sampling and analysis for 1,4-
dioxane (SIM) be dropped at all lined MSW landfill monitor wells (MW-1, MW-2, MW-2A, MW-3, MW-4A,
MW-51, MW-52, MW-53, MW-64 and MW-BG) and surface water locations (SW-1, SW-2, SW-3, SW-4, SW-
5 and SW-6); and at upgradient groundwater monitor well MW-7 at the C&D landfill; each meeting the new
NCSWS 1,4-dioxane (SIM) criteria. However, these samples would continue to be analyzed for 1,4-dioxane
(non-SIM; EPA 8260D: MDL = 13 ug/l and PQL = 50 ug/1) as part of the standard Appendix I VOC analysis,
for continued monitoring purposes. All historical leachate samples (LEACHATE) collected from the lined
MSW leachate sump have indicated the presence of 1,4-dioxane ranging from 28 to 150 ug/l. The leachate
sample at the lined MSW landfill will continue to be analyzed for 1,4-dioxane (SIM) on a semi-annual basis, as
required by the NCSWS.
On March 3, 2020, Mr. Perry Sugg, P.G. with the NCSWS issued a Section Response to Request for Reduction
in 1,4-Dioxane Sampling letter for the subject site. The NCSWS response letter indicated that semi-annual
sampling and analysis for 1,4-dioxane (SIM) at all lined MSW landfill groundwater compliance monitor wells;
and MW-7 at the C&D landfill, could be reduced to every -other -year. Mr. Sugg further clarified during a
subsequent email conversation that 1,4-dioxane (SIM) monitoring would only be required to be conducted
once/year every -other -year on odd years starting in 2021 at all lined MSW landfill monitor wells and at C&D
landfill monitor well MW-7; and would not be required to be conducted at any of these monitor wells during
semi-annual sampling on even years, beginning in 2020. The NCSWS response letter indicated that semi-
annual sampling and analysis for 1,4-dioxane (SIM) at all surface water locations (except at SW-2, which is
located between the C&D and lined MSW landfills) could be discontinued. Semi-annual monitoring for 1,4-
dioxane (SIM) will continue at surface water sample SW-2 (due to detections of 1,4-dioxane above the NCGPS
or MDL at C&D landfill monitor wells MW-5, MW-5R and MW-6); and the lined MSW leachate sump.
During the second semi-annual 2021 sampling event (which included once every fourth semi-annual sampling /
odd -year 1,4-dioxane (SIM) analysis at all on -site monitor wells and surface water locations), lined MSW
landfill groundwater samples MW-2, MW-2A and MW-53 and surface water samples SW-3 and SW-4,
indicated J-flagged 1,4-dioxane (SIM) above the MDL. Based on this information, lined MSW landfill samples
MW-2, MW-2A, MW-53, SW-3 and SW-4 will be included along with existing C&D landfill samples MW-5,
MW-5, MW-7 and SW-2 for 1,4-dioxane (SIM) analysis during future semi-annual sampling events until 1,4-
dioxane has not been detected above the MDL for two (2) consecutive events.

3,0 GROUNDWATER, SURFACE WATER AND LEACHATE MONITORING
On April 7 and 8, 2022, Buxton Environmental, Inc. conducted the first semi-annual 2022 groundwater, surface
water and leachate monitoring, and even year 1,4-dioxane (SIM) monitoring schedule event at the subject site.
Groundwater monitoring activities were conducted at ten (10) lined MSW landfill monitor wells including MW-
1, MW-2, MW-2A, MW-3, MW-4A, MW-51, MW-52, MW-53, MW-64 and MW-BG; and four (4) C&D
landfill monitor wells including MW-5, MW-5R, MW-6 and MW-7. Monitor wells MW-52 and MW-BG are
upgradient background wells for the lined MSW landfill; and MW-7 is the upgradient background well for the
C&D landfill. The remaining monitor wells are side/downgradient compliance wells for the respective landfill
areas. Surface water monitoring was conducted at six (6) locations including SW-1, SW-2, SW-3, SW-4, SW-5
and SW-6. Surface water sampling was not conducted at SW-7 (lined landfill underdrain), since it was not
requested by Alamance County. A leachate sample, LEACHATE, was also collected from the lined MSW
landfill leachate sump.
Prior to conducting groundwater sampling activities, groundwater levels were obtained from each well to the
nearest 0.01 foot with a depth -to -water electrode. Groundwater gauging data is provided in Table 1.
Following the gauging activities, monitor wells at the lined MSW landfill (MW-1, MW-2, MW-2A, MW-3,
MW-4A, MW-51, MW-52, MW-64 and MW-BG); and C&D landfill (MW-5, MW-5R, MW-6 and MW-7)
were slowly purged (to attempt to reduce turbidity) until a minimum of 3 well bore volumes of water had been
removed or until dryness with a disposable Teflon bailer attached to new nylon rope. Purge water was poured
on the ground surface at respective well heads. Field parameters including pH, conductivity and temperature
were collected following purging at each groundwater monitor well, and prior to sampling at each surface water
sample location and the leachate sump with a calibrated HANNA-HI 9812-5 meter. Groundwater samples
collected at the lined MSW landfill were also measured for turbidity with an AMTAST-AMT27 turbidity meter.
Field parameter data is provided in Table 2.
Groundwater samples collected at lined MSW landfill monitor wells (MW-1, MW-2, MW-2A, MW-3, MW-4A,
MW-51, MW-52, MW-64 and MW-BG); surface water samples (SW-1, SW-2, SW-3, SW-4, SW-5 and SW-6);
and leachate sample (LEACHATE) were analyzed for Appendix I VOCs (plus 1,4-dioxane (non-SIM)) by EPA
Method 8260D, and Appendix I metals (antimony, arsenic, barium, beryllium, cadmium, chromium, cobalt,
copper, lead, nickel, selenium, silver, thallium, vanadium and zinc) by EPA Method 6020B. Lined MSW
landfill groundwater samples MW-2, MW-2A and MW-53, and surface water samples SW-3 and SW-4 were
also analyzed for 1,4-dioxane by EPA Method 8260D (SIM) (to achieve the 3 ug/l LOQ/PQL requirement).
The LEACHATE sample was also analyzed for additional inorganic parameters including BOD by EPA
Method SM 5210B-2011, COD by EPA Method SM 5220D-2011, orthophosphate by EPA Method 365.1,
sulfate by EPA Method 300.0, TSS by EPA Method SM 2540D-2011, ammonia as nitrogen (N) by EPA
Method 350.1 and total cyanide by EPA Method 9012B. Groundwater samples collected at C&D landfill
monitor wells (MW-5, MW-5R, MW-6 and MW-7) were analyzed for Appendix I VOCs (plus tetrahydrofuran
and 1,4-dioxane (non-SIM)) by EPA Method 8260D, 1,4-dioxane by EPA Method 8260D (SIM), Appendix I
metals by EPA Method 6020B; and additional C&D parameters including alkalinity by EPA Method SM
2320B-2011, chloride by EPA Method 300.0, sulfate by EPA Method 300.0, total dissolved solids (TDS) by
EPA Method SM2540C-2011, and iron and manganese by EPA Method 200.7. For quality control purposes,
one duplicate groundwater sample MW-55 (duplicate groundwater sample at MW-5) was collected and
analyzed for Appendix I VOCs (plus 1,4-dioxane (non-SIM) and tetrahydrofuran) by EPA Method 8260D and
1,4-dioxane by EPA Method 8260D (SIM). In addition, one trip blank was analyzed for Appendix I VOCs by
EPA Method 8260D (plus 1,4-dioxane (non-SIM)). The trip blank was prepared by the laboratory; and traveled
with the empty sample bottles in a cooler from the lab to Buxton Environmental, Inc., then back to the lab in the
cooler with groundwater samples. The samples were analyzed by Pace Analytical Services, LLC (North

Carolina License # 329) in West Columbia, South Carolina. The water samples were collected in general
accordance with accepted protocol, immediately placed in laboratory supplied containers, appropriately labeled
(with sample identification, location, date and time), placed in a cooler with wet ice and transferred to the
laboratory with chain -of -custody documentation.
During the groundwater sampling activities, Buxton Environmental, Inc. conducted a routine up -keep and
maintenance inspection at on -site monitor wells, in order to comply with the March 23, 2017 memorandum
from the NCSWS. The monitor wells were locked, appeared to be in good condition, and in compliance with
NCSWS standards.

4.0 SITE HYDROGEOLOGY
4.1 Shallow Groundwater Flow Direction and Rate
Based on groundwater levels obtained on April 7 and 8, 2022 during the first semi-annual 2022 event, the
predominant shallow groundwater flow directions in the area of the lined MSW landfill are to the northwest,
southwest and south toward the Haw River located along the southwest property boundary or associated
intermittent tributary creeks. Shallow groundwater flow at the C&D landfill is to the south southwest. A
shallow groundwater flow direction map is provided in Figure 3. The groundwater hydraulic gradient, flow
direction, hydraulic conductivity and average linear groundwater velocity for each lined landfill monitor well is
provided in Table 3.
A horizontal hydraulic gradient of 0.029 feet per feet (ft/ft) was observed between shallow monitor wells MW-
52 and MW-2 at the lined MSW landfill. A downward vertical hydraulic gradient of 0.023 ft/ft was observed
between nested monitor wells MW-2 and MW-2A at the lined landfill. Downward vertical gradients are
generally associated with groundwater recharge zones and upward vertical gradients are generally associated
with groundwater discharge zones.
A horizontal hydraulic gradient of 0.045 ft/ft was observed between shallow monitor wells MW-7 and MW-6 at
the C&D landfill.
Average linear groundwater velocities in the immediate area of each lined MSW landfill monitor well were
determined using the following equation developed by Darcy (1856) (as described in Fetter (1988)).:
V = K/n x dh/dl
X
Where: VX = average linear groundwater velocity (ft/day)
K = hydraulic conductivity at respective well (ft/day)
n = total porosity (25% or 0.25 (inferred for sand))
dh/dl = hydraulic gradient (ft/ft) in the vicinity of the respective well
The average linear groundwater velocity for the aquifer at the lined MSW landfill ranged from 0.0002 feet per
day (ft/day) (0.073 feet per year (ft/yr)) at monitor well MW-4A to 0.053 ft/day (19.35 ft/yr) at monitor well
MW-52.

5.0 GROUNDWATER, SURFACE WATER AND LEACHATE ANALYTICAL RESULTS
The groundwater analytical results for the lined MSW landfill are provided in Table 4. The groundwater
analytical results for the C&D landfill are provided in Table 5. The surface water analytical results are provided
in Table 6. Leachate analytical results are presented in Table 7. Groundwater analytical results for the lined
MSW and C&D landfills, and surface water analytical results are provided in Figure 4. Laboratory data sheets
are presented in Appendix B.
Groundwater Analytical Results - Lined MSW Landfill
The groundwater samples collected at MW-2 and MW-53 indicated target Appendix I metals constituents above
NCGPSs, which are summarized below. The groundwater sample collected at monitor well MW-2 indicated
the presence of 7 ug/1 cobalt. The groundwater sample collected at monitor well MW-53 indicated the presence
of 2,300 ug/1 barium, 5.9 ug/1 beryllium, 54 ug/l cobalt, 19 ug/1 lead and 460 ug/1 vanadium, which appear to be
the result of turbidity caused by low water conditions in the well. The remaining groundwater samples
collected at monitor wells MW-1, MW-2A, MW-3, MW-4A, MW-51, MW-52, MW-64 and MW-BG did not
indicate target Appendix I VOCs (including 1,4-dioxane (non-SIM or SIM)) or metal constituents above
NCGPSs.
Groundwater samples collected at monitor wells MW-2, MW-2A and MW-53 did not indicate the presence of
1,4-dioxane (SIM) above method detection limits.
No target Appendix I VOC or metal constituents exceeded the NCGPSs for the first-time in groundwater
samples collected at the lined MSW landfill during the first semi-annual 2022 event.
Groundwater Analytical Results — C&D Landfill
Groundwater samples collected at monitor wells MW-5, MW-5R, MW-6 and MW-7 indicated the presence of
target constituents above NCGPSs, which are summarized below. Groundwater samples collected at monitor
well MW-5 indicated the presence of 17 ug/1 tetrahydrofuran (NCGPS not established), 8.9 ug/l 1,4-dioxane
(SIM), 25 ug/1 chromium, 23 ug/1 cobalt, 5 ug/l vanadium, 1,400,000 ug/l alkalinity, 280,000 ug/1 sulfate,
2,800,000 ug/1 TDS, 3,700 ug/1 iron and 18,000 ug/1 manganese. Duplicate groundwater sample MW-55
(duplicate of MW-5) indicated 18 ug/1 tetrahydrofuran and 8.9 ug/l 1,4-dioxane (SIM). Groundwater samples
collected at monitor well MW-5R indicated the presence of 12 ug/l tetrahydrofuran, 7.4 ug/l 1,4-dioxane (SIM),
60 ug/1 cobalt, 900,000 ug/1 alkalinity, 260,000 ES ug/1 sulfate, 1,500,000 ug/l TDS, 4,800 ug/l iron and 14,000
ug/1 manganese. An E-flag indicates that the quantitation of the compound exceeded the calibration range and
an S-flag indicates that the matrix spike/matrix spike duplicate (MS/MSD) was recovered outside of acceptable
limits, therefore, these results are estimated. Groundwater samples collected at monitor well MW-6 indicated
the presence of 350,000 ug/1 alkalinity, 530,000 ug/1 TDS and 2,600 ug/1 manganese. Groundwater samples
collected at monitor well MW-7 indicated the presence of 41,000 ug/1 alkalinity.
The groundwater sample collected at monitor well MW-6 also indicated the presence of 1.1J ug/l 1,4-dioxane
(SIM), which is above the MDL but are less than the NCGPS of 3 ug/l.
No target constituents exceeded NCGPSs for the first-time in groundwater samples collected at the C&D
landfill during the first semi-annual 2022 event.

According to information obtained from EPA websites, sulfate, TDS, iron and manganese are naturally
occurring constituents, and the EPA has established non -enforceable Secondary Maximum Contaminant Levels
(SMCLs) in drinking water for these constituents for aesthetic considerations such as taste, color and odor. The
EPA SMCLs were set to give public water systems some guidance on removing these constituents to levels to
below what most people find noticeable.
Surface Water Analytical Results
Surface water samples SW-3 and SW-4, which were upstream and downstream samples collected along the
Haw River, indicated the presence of 3.1 ug/l and 3.2 ug/1 1,4-dioxane (SIM), respectively, above the lowest of
established: North Carolina Surface Water and Wetland Standards (15A NCAC 02B) (Redbook, May 1,
2007)(NC2BRB); North Carolina 15A NCAC 02B Water Quality Standards for Surface Water (June 10, 2019)
(NC2B); or North Carolina In -Steam Target Values for Surface Water (NCTSW) for the Haw River (Class WS-
V water); or EPA National Recommended Water Quality Criteria for Aquatic Life and Human Health (EPA),
which are collectively referred to in this report as North Carolina Surface Water and Wetland Standards
(NCSWWSs). The 1,4-dioxane detected at SW-3 and SW-4 appear to be the result of an upgradient off -site
source and are not associated the Alamance County — Austin Quarter Landfill, based on historical sampling
data. Detected constituents without established standards were not considered exceedances of NCSWWSs. The
remaining surface water samples, including SW-1, SW-2, SW-5 and SW-6 did not indicate the presence of
target Appendix I VOC (including 1,4-dioxane non-SIM or SIM (SW-2)) or metal constituents above
established NCSWWSs.
Surface water samples SW-1, SW-2, SW-5 and SW-6 did not indicate the presence of 1,4-dioxane (non-SIM)
above method detection limits.
Leachate Analytical Results — Lined MSW Landfill
The LEACHATE sample collected from the on -site leachate collection sump for the lined MSW landfill
indicated the presence of 35 HJ ug/l 2-butanone, 7.2 HJ ug/1 1,4-dichlorobenzene, 12 H ug/1 xylenes, 91 ug/1
1,4-dioxane (SIM), 930 ug/1 barium, 53J ug/1 chromium, 34J ug/1 cobalt, 85J ug/l nickel, 63J ug/l
vanadium,530,000 ug/l ammonia as N, 45,000 ug/l BOD, 960,000 ug/l COD, 5.9J ug/l cyanide, 2,500 H ug/l
orthophosphate and 12,000 ug/l TSS. An H-flag indicates that the sample was analyzed outside of EPA method
holding time.
Quality Control Analytical Results
The trip blank did not indicate the presence of Appendix I VOCs (including 1,4-dioxane and tetrahydrofuran)
above method detection limits.

6.0 STATISTICAL GROUNDWATER EVALUATIONACTIVITIES
Buxton Environmental, Inc. conducted a statistical evaluation of historical Appendix I groundwater analytical
data collected from December 10, 1993 until April 8, 2022 (this first semi-annual 2022 event) at the lined MSW
landfill. These activities were conducted to determine if groundwater constituents detected at downgradient
compliance wells MW-1, MW-2, MW-2A, MW-3, MW-4A, MW-51, MW-53 and MW-64 indicated a
significant increase above groundwater constituents detected at dual upgradient background monitor wells MW-
BG and MW-52.
J-flagged groundwater constituents were not statistically evaluated during the assessment, since the data is
estimated. B-flagged groundwater data (detected in method blank) was utilized in the statistics.
6.1 Statistical Groundwater Evaluation Methods
The statistical groundwater evaluation was conducted using computer software entitled A Ground Water
Information Tracking System with Statistical Analysis Capability, GRITS/STAT v4.2 dated November 1992.
The GRITS/STAT program was developed by the U.S. Environmental Protection Agency (EPA) for the
statistical evaluation of groundwater quality data at RCRA, CERCLA and other regulated facilities.
In order to determine the most appropriate statistical method to evaluate the groundwater data, a Shipiro-Wilk
Test was first conducted to determine the normality of the data. The groundwater data primarily showed
evidence of having a non -normal distribution. Based on the distribution and percentage of detected target
constituents at the site, the Kruskal-Wallis Test was selected to evaluate the historical groundwater data. A
description of the selected method is provided below.
Kruskal-Wallis Test (Nonparametric Analyses of Variance)
The Kruskal Wallis Test is a nonparametric analyses of variance (ANOVA), which is utilized to test the
hypothesis that all background and compliance wells possess the same median concentration of a groundwater
constituent. If the hypothesis of equal medians is rejected, then GRITS/STAT performs additional calculations
to determine which compliance wells indicate statistical evidence of groundwater contamination.
The Kruskal-Wallis Test is recommended to be conducted on groundwater data which is non -normally
distributed and possess a percentage of non -detects of less than 50. This method requires a minimum of two
compliance wells and one background well, and a minimum of four sampling events.

6.2 Statistical Groundwater Evaluation Results
The results of the statistical groundwater evaluation utilizing the Kruskal-Wallis Test are presented in Table 8.
The supporting statistical evaluation data is maintained on -file with Buxton Environmental, Inc. A summary of
the findings is presented below.
Historical groundwater samples collected at monitor well MW-I indicated a statistically significant increase in
barium above background concentrations.
Historical groundwater samples collected at monitor well MW-2 indicated a statistically significant increase in
barium, cobalt and vanadium above background concentrations.
No statistically significant groundwater constituents were identified at monitor well MW-2A.
Historical groundwater samples collected at monitor well MW-3 indicated a statistically significant increase in
barium above background concentrations.
Historical groundwater samples collected at monitor well MW-4A indicated a statistically significant increase
in copper above background concentrations.
Historical groundwater samples collected at monitor well MW-51 indicated a statistically significant increase in
barium above background concentrations.
Historical groundwater samples collected at monitor well MW-53 indicated a statistically significant increase in
barium, cobalt, copper, lead, vanadium and zinc above background concentrations.
Historical groundwater samples collected at monitor well MW-64 indicated a statistically significant increase in
barium and copper above background concentrations.

7.0 CONCL USIONS
On April 7 and 8, 2022, Buxton Environmental, Inc. conducted the first semi-annual 2022 groundwater, surface
water and leachate monitoring, and even year 1,4-dioxane (SIM) monitoring schedule activities conducted at the
Alamance County -Austin Quarter Landfill (Permit No.: 0104) located at 2701 Austin Quarter Road near
Saxapahaw in Alamance County, North Carolina. A summary of the findings of this investigation is provided
below.
During the second semi-annual 2021 sampling event (which included once every fourth semi-annual
sampling / odd -year 1,4-dioxane (SIM) analysis at all on -site monitor wells and surface water locations),
lined MSW landfill groundwater samples MW-2, MW-2A and MW-53 and surface water samples SW-3
and SW-4, indicated J-flagged 1,4-dioxane (SIM) above the MDL. Based on this information, lined
MSW landfill samples MW-2, MW-2A, MW-53, SW-3 and SW-4 will be included along with existing
C&D landfill samples MW-5, MW-5, MW-7 and SW-2 for 1,4-dioxane (SIM) analysis during future
semi-annual sampling events until 1,4-dioxane has not been detected above the MDL for two (2)
consecutive events.
• Buxton Environmental, Inc. conducted a routine up -keep and maintenance inspection at on -site monitor
wells, in order to comply with the March 23, 2017 memorandum from the NCSWS. The monitor wells
were locked, appeared to be in good condition, and in compliance with NCSWS standards.
• The predominant shallow groundwater flow directions in the area of the lined MSW landfill are to the
northwest, southwest and south toward the Haw River located along the southwest property boundary or
associated intermittent tributary creeks. A horizontal hydraulic gradient of 0.029 feet per feet (ft/ft) was
observed between shallow monitor wells MW-52 and MW-2 at the lined MSW landfill. A downward
vertical hydraulic gradient of 0.023 ft/ft was observed between nested monitor wells MW-2 and MW-2A
at the lined landfill. The average linear groundwater velocity for the aquifer at the lined MSW landfill
ranged from 0.0002 feet per day (ft/day) (0.073 feet per year (ft/yr)) at monitor well MW-4A to 0.053
ft/day (19.35 ft/yr) at monitor well MW-52.
Shallow groundwater flow at the C&D landfill is to the south southwest. A horizontal hydraulic
gradient of 0.045 ft/ft was observed between shallow monitor wells MW-7 and MW-6 at the C&D
landfill.
The groundwater samples collected at MW-2 and MW-53 indicated target Appendix I metals
constituents above NCGPSs, which are summarized below. The groundwater sample collected at
monitor well MW-2 indicated the presence of 7 ug/l cobalt. The groundwater sample collected at
monitor well MW-53 indicated the presence of 2,300 ug/l barium, 5.9 ug/l beryllium, 54 ug/l cobalt, 19
ug/l lead and 460 ug/l vanadium, which appear to be the result of turbidity caused by low water
conditions in the well. The remaining groundwater samples collected at monitor wells MW-1, MW-2A,
MW-3, MW-4A, MW-51, MW-52, MW-64 and MW-BG did not indicate target Appendix I VOCs
(including 1,4-dioxane (non-SIM or SIM)) or metal constituents above NCGPSs.
• Groundwater samples collected at monitor wells MW-2, MW-2A and MW-53 did not indicate the
presence of 1,4-dioxane (SIM) above method detection limits.
• No target Appendix I VOC or metal constituents exceeded the NCGPSs for the first-time in groundwater
samples collected at the lined MSW landfill during the first semi-annual 2022 event.

Groundwater samples collected at monitor wells MW-5, MW-5R, MW-6 and MW-7 indicated the
presence of target constituents above NCGPSs, which are summarized below. Groundwater samples
collected at monitor well MW-5 indicated the presence of 17 ug/l tetrahydrof Iran (NCGPS not
established), 8.9 ug/1 1,4-dioxane (SIM), 25 ug/1 chromium, 23 ug/l cobalt, 5 ug/l vanadium, 1,400,000
ug/1 alkalinity, 280,000 ug/1 sulfate, 2,800,000 ug/1 TDS, 3,700 ug/l iron and 18,000 ug/l manganese.
Duplicate groundwater sample MW-55 (duplicate of MW-5) indicated 18 ug/1 tetrahydrofuran and 8.9
ug/1 1,4-dioxane (SIM). Groundwater samples collected at monitor well MW-5R indicated the presence
of 12 ug/1 tetrahydrofuran, 7.4 ug/l 1,4-dioxane (SIM), 60 ug/1 cobalt, 900,000 ug/1 alkalinity, 260,000
ES ug/1 sulfate, 1,500,000 ug/1 TDS, 4,800 ug/1 iron and 14,000 ug/l manganese. Groundwater samples
collected at monitor well MW-6 indicated the presence of 350,000 ug/1 alkalinity, 530,000 ug/l TDS and
2,600 ug/1 manganese. Groundwater samples collected at monitor well MW-7 indicated the presence of
41,000 ug/1 alkalinity.
The groundwater sample collected at monitor well MW-6 also indicated the presence of 1.1J ug/1 1,4-
dioxane (SIM), which is above the MDL but are less than the NCGPS of 3 ug/l.
• No target constituents exceeded NCGPSs for the first-time in groundwater samples collected at the C&D
landfill during the first semi-annual 2022 event.
Surface water samples SW-3 and SW-4, which were upstream and downstream samples collected along
the Haw River, indicated the presence of 3.1 ug/1 and 3.2 ug/l 1,4-dioxane (SIM), respectively, above the
NCSWWSs. The 1,4-dioxane detected at SW-3 and SW-4 appear to be the result of an upgradient off -
site source and are not associated the Alamance County — Austin Quarter Landfill, based on historical
sampling data. The remaining surface water samples, including SW-1, SW-2, SW-5 and SW-6 did not
indicate the presence of target Appendix I VOC (including 1,4-dioxane non-SIM or SIM (SW-2)) or
metal constituents above established NCSWWSs.
• Surface water samples SW-1, SW-2, SW-5 and SW-6 did not indicate the presence of 1,4-dioxane (non-
SIM) above method detection limits.
• The LEACHATE sample collected from the lined landfill leachate sump indicated numerous Appendix I
VOCs (including 1,4-dioxane (SIM)) and metals, and additional inorganic constituents.
Based on statistical evaluation of historical Appendix I groundwater analytical data collected from
December 10, 1993 until April 8, 2022 (this first semi-annual 2022 event) at the lined MSW landfill:
monitor well MW-1 indicated barium; MW-2 indicated barium, cobalt and vanadium; MW-3 indicated
barium; MW-4A indicated copper; MW-51 indicated barium; MW-53 indicated barium, cobalt, copper,
lead, vanadium and zinc; and MW-64 indicated barium and copper above background concentrations.
No statistically significant groundwater constituents were identified at monitor well MW-2A.

8.0 RECOMMENDATIONS
Based on the findings of this assessment, Buxton Environmental, Inc. makes the following recommendations.
Semi-annual Appendix I groundwater, surface water and leachate Detection Monitoring should continue
to be conducted at the lined MSW landfill, in general accordance with NCSWS Rules, guidelines and
discussions with the NCSWS. The next monitoring event is anticipated to be conducted in October
2022 at all groundwater monitor wells, surface water sampling locations and the leachate sump, and will
consist of analyses including: Appendix I VOCs (plus 1,4-dioxane (non-SIM)) and metals.
Groundwater samples MW-2, MW-2A and MW-53 and surface water samples SW-3 and SW-4, which
indicated J-flagged 1,4-dioxane above the MDL (during the second semi-annual 2021, once every fourth
semi-annual sampling/odd-year sampling schedule event) will also be analyzed for 1,4-dioxane (SIM)
during future semi-annual sampling events until 1,4-dioxane has not been detected above the MDL for
two (2) consecutive events. The LEACHATE sample will also be analyzed for 1,4-dioxane (SIM) and
additional inorganic parameters as required by the NCSWS.
The Assessment Monitoring Program / Alternate Source Demonstration Investigation Report for the
metals exceedances at the lined MSW landfill is in the final stage of completion and will be submitted
NCSWS.
The next semi-annual Detection and Assessment Monitoring event at the C&D landfill is anticipated to
be conducted in October 2022 at groundwater monitor wells MW-5, MW-5R, MW-6 and MW-7; and
will consist of biennial Appendix II Assessment Monitoring, which will include: full Appendix II
constituents plus 1,4-dioxane (non-SIM) and tetrahydrofuran, 1,4-dioxane (SIM), along with additional
C&D parameters. Surface water sample SW-2 will be analyzed for Appendix I VOCs (plus 1,4-dioxane
(non-SIM) and tetrahydrofuran) and metals, and 1,4-dioxane (SIM).
• Future groundwater sampling at the site should continue to be conducted with non-metallic down -hole
sampling devices, in order to remove the possibility for field introduced metals contamination.
• A copy of this report should be forwarded to the NCSWS for their review.

APPENDIX A
Historical Background Information

HISTORICAL BACKGROUND INFORMATION
Buxton Environmental, Inc. understands that the Alamance County -Austin Quarter Landfill consists of
approximately 423 acres and has been in operation since approximately 1993. The subject property presently
contains an active lined Subtitle D MSW landfill on the southern side of the site; and a temporarily closed
unlined C&D landfill on the northern side of the site (ceased receiving waste in September 2017). The lined
MSW landfill is equipped with an impermeable geosynthetic underliner and a leachate collection system.
Leachate from the lined MSW landfill flows into a leachate sump, which is pumped into aboveground storage
tanks located to the north of the lined cell.
Two water supply wells, Water Supply Well No.: 1 and Water Supply Well No.: 2, are utilized by the Alamance
County -Austin Quarter Landfill (Figure 2). Water Supply Well No.: 1 is located along Austin Quarter Road,
adjacent to the north -central tip of the landfill property (on additional property owned by Alamance County)
and is approximately 1,500 feet north and upgradient of the C&D landfill. Water Supply Well No.: 2 is located
on the east -central property boundary (approximately 400 feet southwest of new background monitor well MW-
BG); and is approximately 1,800 feet northeast and upgradient of the lined MSW landfill, and approximately
1,600 feet east and upgradient of the C&D landfill.
Based on review of historical data, Appendix I (VOCs and metals) groundwater and surface water sampling was
conducted at the site from December 1993 until March 2002 by other consulting firms. During these activities,
only metals were detected above NCGPSs. The metals detected at the site during this time appear to be the
result of sample turbidity and/or natural conditions. However, tetrachloroethene was detected above the
NCGPS at surface water samples SW-1, SW-5 and SW-6 and monitor well MW-1 during the first semi-annual
2002 sampling event, according to a March 29, 2002 Report of Semi -Annual Water Quality Monitoring, Series 2
prepared by Law Engineering and Environmental Services, Inc. (LAW). The tetrachloroethene was later
determined to be the result of laboratory contamination, based on an April 19, 2002 letter prepared by LAW.
These tetrachloroethene false positives are not considered in the historical groundwater analytical results
database for the site.
Buxton Environmental, Inc. has conducted groundwater, surface water and leachate sampling at the site since
September 2002. Groundwater samples collected at the lined MSW landfill have historically only indicated the
presence Appendix I metals above NCGPSs; however, former background monitor well MW-50R indicated the
presence of vinyl chloride (chlorinated VOC) at concentrations of 1 microgram per liter (ug/1) and 0.8 ug/1
(confirmation sample) during the first semi-annual 2015 groundwater sampling event, which were above the
NCGPS of 0.03 ug/l. Monitor well MW-50R was located approximately 98 feet to the north and
hydrogeolocially side to downgradient of the edge of the MSW liner. Detections of vinyl chloride above the
NCGPS at monitor well MW-50R were sporadic during subsequent semi-annual groundwater monitoring
events. MW-50R did not indicate vinyl chloride above the NCGPS during the last three (3) sampling events,
which include an October 17, 2017 sampling event for Appendix I VOCs conducted by Municipal Engineering
Services Company, PA (Municipal Engineering; site engineer); and routine Appendix I semi-annual sampling
conducted by Buxton Environmental, Inc. on October 30, 2017 and March 27, 2018; however, estimated J-
flagged vinyl chloride detections of 0.63J ug/l, 0.65J ug/l and 0.86J ug/l were reported, respectively.
Groundwater samples collected at MW-50 / MW-50R have also indicated Appendix I metals including arsenic,
barium, beryllium, cadmium chromium, cobalt, lead, thallium and vanadium above NCGPSs since background
sampling began in March 2000, which are consistent with naturally occurring background conditions and can be
exacerbated by elevated turbidity conditions. Appendix I surface water samples collected at the Alamance
County Austin Quarter landfill have also indicated the presence of metals above established North Carolina
Surface Water and Wetland Standards (15A NCAC 02B) for the Haw River (Class WS-V water) (NCSWWSs).
Groundwater samples collected at the C&D landfill have historically only indicated metals above NCGPSs;

however, downgradient compliance monitor well MW-5 indicated the presence of 1.5 ug/l vinyl chloride during
the second semi-annual 2010 groundwater sampling event, which was above the NCGPS. Detections of vinyl
chloride above the NCGPS at monitor well MW-5 or duplicate sample MW-55 have been sporadic during
subsequent semi-annual groundwater monitoring events. Groundwater samples MW-5, MW-6 and MW-7
(upgradient background well), which are located at the C&D landfill, have also historically indicated the
presence of several required additional inorganic C&D parameter constituents above NCGPSs (prior to
commencement of Appendix II Assessment Monitoring). Groundwater sample MW-5 has indicated the
presence of sulfate, total dissolved solids (TDS), iron and manganese. Groundwater sample MW-6 has
indicated the presence of iron and manganese. Groundwater sample MW-7 has indicated the presence of iron
and manganese.
According to NCSWS Rules .1634 (for MSW landfills) and .0545 (for C&D landfills), an Assessment
Monitoring Program is required to be established if one or more target constituent is detected above NCGPSs.
The Assessment Monitoring Program primarily consists of determining the nature and extent of the release, and
initiating sampling for Appendix II groundwater constituents (includes expanded VOC and metal lists, SVOCs,
herbicides, pesticides, PCBs, cyanide and sulfide). Assessment Monitoring is not required if an Alternate
Source Demonstration can be made.
Monitor well MW-50 was damaged during landfilling activities and was replaced with monitor well MW-50R
in 2005. Monitor well MW-50R was installed at the location of and to a similar depth as MW-50. Buxton
Environmental, Inc. understands that the NCSWS authorized the abandonment of monitor well MW-50R
following an assessment conducted in October 2018 by Municipal Engineering (details concerning the rationale
for this abandonment is discussed further in the background section).
Two additional monitor wells, MW-53 and MW-64, were installed to monitor groundwater at the lined MSW
landfill expansion (Cell 2A). Initial Appendix I groundwater sampling was conducted at these wells on
December 23, 2005.
Alamance County Landfill requested that biological oxygen demand (BOD), chemical oxygen demand (COD),
sulfate, nitrate and phosphate be added to routine groundwater sampling at the lined MSW landfill leachate
sump during the first semi-annual 2006 event. Alamance County Landfill requested that mercury be added to
routine sampling at the leachate sump during the second semi-annual 2006 event. Alamance County Landfill
requested that total suspended solids (TSS) and cyanide be added to routine sampling at the leachate sump
during the second semi-annual 2010 event.
On April 12, 2011 and May 7, 2013, Mr. Ervin Lane with the NCSWS was contacted to discuss the detections
of vinyl chloride above the NCGPS in groundwater at monitor well MW-5 located at the C&D landfill. During
the conversation, Mr. Lane indicated that an Assessment Monitoring Program would not be required at the
C&D landfill until conclusive evidence of a groundwater exceedance has occurred.
On September 22, 2011, Mr. Ervin Lane with the NCSWS was contacted to discuss exceedances of several
additional inorganic C&D parameters historically detected in groundwater samples collected at the C&D
landfill. Mr. Lane indicated that Detection Monitoring could continue to be conducted at the C&D landfill and
filtering of groundwater samples may be warranted in the future.
On April 29, 2015, Mr. Ervin Lane with the NCSWS indicated that Detection Monitoring could continue to be
conducted at monitor wells MW-5 (downgradient well at the C&D landfill, which has sporadically indicated
vinyl chloride above the NCGPS since the second semi-annual 2010 event) and MW-50R (former background
well at the lined MSW landfill, which indicated vinyl chloride above the NCGPS for the first time during the

first semi-annual 2015 event). Mr. Lane indicated that an Assessment Monitoring Program would be required
to be implemented if vinyl chloride is consistently detected above the NCGPS at these two monitor wells.
The NCSWS requested in an August 8, 2016 letter that an Assessment Monitoring Program or an Alternate
Source Demonstration be established/conducted within 90 days (as stipulated in NCSWS Rule 15A NCAC 13B
.1633), due to the presence of Appendix I inorganic constituents exceedances (metals) above NCGPSs at the
Alamance County — Austin Quarter lined MSW landfill. On October 24, 2016, Buxton Environmental, Inc.
submitted an extension request to the NCSWS to assess/evaluate Appendix I inorganic constituents (metals) at
the site. The Assessment Monitoring Program / Alternate Source Demonstration Investigation Report was
proposed to be completed and submitted to the NCSWS on or by November 30th, 2017. The NCSWS approved
the extension request in a November 8, 2016 letter. On November 28, 2017, Buxton Environmental, Inc.
obtained a verbal extension from Mr. Lane with the NCSWS to have the Assessment Monitoring Program /
Alternate Source Demonstration Investigation Report completed by February 28, 2018, which was followed -up
with a correspondence letter documenting the conversation. In March 2018, Mr. Ross Klingman, P.G. with
Buxton Environmental contacted Mr. Perry Sugg, P.G. with the NCSWS (new compliance and permitting
manager for the site) to request additional time to complete the Appendix I metals exceedances Assessment
Monitoring or an Alternate Source Demonstration Report. All field data and efforts to reduce sampling related
turbidity associated with this assessment have been collected/completed (most of this information has been/will
be submitted to the NCSWS in routine semi-annual groundwater monitoring reports). The Assessment
Monitoring or an Alternate Source Demonstration Report is in the final stage of completion.
Low -purge groundwater sampling was conducted at lined MSW monitor wells MW-1, MW-2, MW-2A, MW-3,
MW-4A, MW-50R, MW-51, MW-52, MW-64 and MW-BG with a stainless -steel Proactive® Mega -Typhoon
pump (constructed of 303 grade stainless steel) from the second -semi-annual 2016 event (September and
November 2016) through the second semi-annual 2017 event (October and November 2017), in order to attempt
to reduce/limit potential sampling related groundwater turbidity as part of the Appendix I metals exceedances
Assessment Monitoring Program / Alternate Source Demonstration Investigation Report. According the 2008
NCSWS groundwater and surface water sampling guidelines, the exterior pump housing must be constructed of
stainless -steel, and the interior pump and moving parts in contact with water must be constructed of stainless -
steel or Teflon. Prior to the September 2016 sampling event, groundwater sampling at the site was conducted
with disposable Teflon bailers attached to new nylon rope.
Recent verification sampling conducted at another North Carolina landfill in February 2018 demonstrated that
use of the stainless -steel Proactive® Mega -Typhoon pump under turbid groundwater conditions can cause
elevated sampling related chromium and nickel concentrations in groundwater samples, as a result of abrasion
of the 303 grade stainless -steel (chromium and nickel rich for improved machinability and non -corrosive
properties) construction of the body or moving parts (i.e. impeller) of the stainless -steel pump. This
information and the potential impact to the quality of groundwater samples collected at the site with the a
stainless -steel Proactive® Mega -Typhoon pump from September 2016 to November 2017 will be addressed in
the Appendix I metals exceedances Assessment Monitoring Program / Alternate Source Demonstration
Investigation Report.
In October 2016, Alamance County Landfill installed a landfill gas interceptor trench between the edge of the
lined MSW landfill and former monitor well MW-50R (which had historically indicated vinyl chloride above
the NCGPS). Buxton Environmental, Inc. understands that former MW-50R has also indicated landfill gas
(including methane), which is a potential source for the recent vinyl chloride groundwater exceedances at MW-
50R. The interceptor trench is approximately 90 foot long by 5 foot wide by 6 foot deep, and is filled with large
boulders. This landfill gas interceptor trench was installed as an attempt to reduce landfill gas levels in the area
of MW-50R; thereby, attempting to reduce vinyl chloride affected groundwater concentrations, and is part of

initial Alternate Source Demonstration assessment activities at the site. We understand that additional trenching
was conducted in the area of MW-50R in 2017, in an attempt to further reduce landfill gas levels.
According to information outlined in Proposed Solutions to Landfill Gas Contamination of Groundwater
prepared in 1999 by GC Environmental, Inc., landfill gas reduction can lower VOC and metal affected
groundwater concentrations by reducing the interaction of groundwater with landfill gas. The article indicates
that VOCs in landfill gas can impact groundwater quality and the landfill gas can alter the natural geologic
chemistry causing metals to more readily dissolve into groundwater.
On October 6, 2016, Buxton Environmental, Inc. contacted Mr. Ervin Lane with the NCSWS to discuss the
detection of the vinyl chloride above the NCGPS at monitor well MW-50R during three (3) of the past four (4)
semi-annual sampling events. Mr. Lane was informed that the landfill gas detected at MW-50R was a potential
source for the vinyl chloride affected groundwater. Based on this information, Mr. Lane requested that an
Alternate Source Demonstration assessment be conducted to determine the source of the vinyl chloride affected
groundwater detected above the NCGPS at monitor well MW-50R, in order to determine if an Assessment
Monitoring Program should be established at the lined MSW landfill.
On October 6, 2016, Buxton Environmental, Inc. contacted Mr. Ervin Lane with the NCSWS to discuss the
sporadic detections of the vinyl chloride above the NCGPS at monitor well MW-5 from 2010 through the
second semi-annual 2016 sampling event. Based on this information, Mr. Lane indicated that an Assessment
Monitoring Program (Appendix II parameter sampling) would be required to be established at the C&D landfill.
On November 4, 2016, SAEDACCO, Inc. (drilling company) with oversight by Municipal Engineering
installed new background monitor well MW-BG to replace background monitor well MW-50R, which is
utilized for the lined MSW landfill. Buxton Environmental, Inc. understands that replacement background
monitor well MW-BG was approved by the NCSWS. Alamance County Landfill subsequently requested for
Buxton Environmental, Inc. to discontinue groundwater monitoring at MW-50R during the first semi-annual
2017 event.
On February 21, 2017, Mr. Ervin Lane with the NCSWS was contacted to discuss the required Assessment
Monitoring activities for the C&D landfill, due the continued presence of target groundwater constituents being
detected above NCGPSs. Mr. Lane indicated that each of the three (3) C&D monitor wells (MW-5, MW-6 and
MW-7) should be initially sampled and analyzed for the full Appendix II parameter list during the first semi-
annual 2017 event conducted in March 2017. Subsequent semi-annual sampling events should be analyzed for
Appendix I volatile organic compounds VOCs and metals plus any additional Appendix II constituents detected
during the initial event for a minimum of three additional semi-annual sampling events, in order to establish
background levels. Following the background Appendix II sampling, periodic sampling for the full Appendix II
parameter list should be conducted. Mr. Lane indicated that additional monitor well installation and
groundwater delineation activities would be required following the background Appendix II sampling activities.
During the first semi-annual 2017 monitoring event conducted on March 29, 2017, Buxton Environmental, Inc.
performed the initial full Appendix II background sampling event at the Alamance County -Austin Quarter C&D
Landfill. Groundwater samples MW-5 (including duplicate sample MW-55), MW-6 and MW-7 indicated the
presence of target constituents above NCGPSs, which are summarized below. Groundwater sample MW-5
indicated the presence of 9 ug/l cobalt, 440,000 ug/l sulfate (NCGPS not established), 760,000 ug/l alkalinity
(NCGPS not established), 1,770,000 ug/l TDS, 320 ug/1 iron and 11,000 ug/1 manganese. Duplicate
groundwater sample MW-55 (duplicate of MW-5) indicated the presence of 4 ug/1 1,2-dichloroethane (first time
exceedance of NCGPS). Groundwater sample MW-6 indicated the presence of 21 ug/l vanadium, 240,000 ug/1
alkalinity, 890 ug/1 iron and 1,200 ug/l manganese. Groundwater sample MW-7 indicated the presence of 390

ug/l iron and 150 ug/l manganese. Groundwater samples collected at monitor wells MW-5, MW-6 and MW-7
did not indicate any Appendix II specific constituents above NCGPSs, however, did indicate several J-flagged
Appendix II specific constituents including SVOCs, pesticides, herbicides, cyanide and/or sulfide above the
MDL. The only non-J-flagged Appendix II constituents detected above the PQL during the initial background
sampling event were cyanide and sulfide at MW-5 and MW-7, respectively. Historical Appendix II
groundwater analytical results for the C&D landfill are provided in Appendix D.
On June 29, 2017, Mr. Ervin Lane with the NCSWS was contacted to obtain clarification and discuss
requirements of the final three (3) Appendix II background sampling events at the C&D landfill. Mr. Lane
indicated that only Appendix II constituents detected above the PQL were required to be tested to complete the
background sampling events, therefore; J-flagged constituents would not be required to be tested. The only
Appendix II specific constituents detected above the PQL during the initial sampling event included cyanide
and sulfide at MW-5 and MW-7, respectively. Based on this information, only the Appendix II specific
constituents including cyanide and sulfide would be required to be tested during subsequent background
sampling events.
On August 18, 2017, Municipal Engineering installed a new shallow downgradient compliance well MW-5R at
the C&D landfill, which is located approximately 70 feet downgradient of MW-5, in order to determine the
horizontal extent of VOCs (namely vinyl chloride) detected at MW-5. The initial groundwater sample collected
at MW-5R by Municipal Engineering on August 22, 2017 did not indicate the presence of Appendix I VOCs
(including vinyl chloride) above MDLs.
In September 2017, Alamance County ceased placing construction and demolition waste at the C&D landfill
due to: 1) the limited remaining space created as a result of construction of the new recycling building located at
and adjacent to future planned landfill areas; 2) an economic feasibility evaluation; and 3) an effort to reduce
potential environmental impact at the C&D area. C&D waste has since been re-routed and placed in the on -site
lined MSW landfill.
On December 1, 2017, Mr. Ross Klingman, P.G. with Buxton Environmental, Inc. on behalf of Alamance
County Landfill, contacted Mr. Ervin Lane with the NCSWS by telephone to obtain clarification for future
groundwater analytical sampling protocol outlined in his November 29, 2017 response letter regarding recent
VOC target constituent detections at groundwater monitor well MW-5 located at the Alamance County — Austin
Quarter C&D Landfill. The November 29, 2017 letter was prepared by Mr. Lane following his October 4, 2017
meeting and review of a subsequent correspondence letter documenting the meeting with/from Alamance
County. The primary purpose of the meeting is understood to have been for Alamance County Landfill to
obtain clarification from the NCSWS on the next course of sampling / assessment / corrective action at the
C&D landfill with regard to historical vinyl chloride (chlorinated solvent - VOC) exceedances above NCGPSs
at downgradient compliance monitor well MW-5. During our conversation, Mr. Lane clarified that he is
presently only concerned with VOCs and other non -naturally occurring Appendix II specific constituents
(namely semi-VOCs, herbicides, pesticides, PCBs), and not all target NCGPS violations. Since no Appendix II
specific constituents were detected above established NCGPSs during the Second Semi -Annual 2017 sampling
event conducted on October 30, 2017 (2nd background Appendix II event) at monitor wells MW-5, MW-5R,
MW-6 or MW-7, Mr. Lane indicated that only MW-5 should be tested for the full Appendix II constituent list
on an annual basis, and that remaining wells including MW-5R, MW-6 and MW-7 should only be tested for
Appendix I constituents (including additional parameters required for C&D landfills) plus any well specific
Appendix II constituents detected above quantifiable detection limits (NCSWS — SWSL, PQL or LOQ).
However, if the NCGPS for a given Appendix lI constituent is below the SWSL, PQL or LOQ, then J-flagged
non -quantified estimated results would also need to be considered (further clarification (FC#1) by Mr. Lane on
December 7, 2017) for two (2) more semi-annual monitoring events, in order to complete the required four (4)

independent Appendix II background monitoring events. MW-5 should also be tested for Appendix I
constituents (including additional parameters required for C&D landfills) plus any well specific Appendix II
constituents detected above quantifiable limits or FC#1 semi-annually until the four (4) Appendix II background
monitoring events are complete. Mr. Lane was also informed that the groundwater samples collected at MW-5
(and duplicate sample MW-55) on October 30, 2017 had J-flagged vinyl chloride detections of 0.71J ug/1 and
0.74J ug/l, respectively, which he agreed did not constitute an exceedance of NCGPSs (the NCGPS for vinyl
chloride is 0.03 ug/l, which was well below the NCSWS-SWSL of 1 ug/1 and standard laboratory
instrumentation capabilities). Mr. Lane agreed that once the required four (4) Appendix II background
monitoring events have been completed at C&D monitor wells MW-5, MW-5R, MW-6 and MW-7, then we
could discuss a new sampling schedule for the C&D landfill. Buxton Environmental, Inc. understands,
according to the November 29, 2017 letter from the NCSWS, that Alamance County is not required to conduct
additional assessment or initiate corrective action at this time, since there no know NCGPS or 2L NCGQS
violations beyond the compliance boundary (generally defined as 250' from edge of waste).
During the December 1, 2017 telephone conversation with Mr. Lane, Mr. Ross Klingman, P.G. with Buxton
Environmental, Inc. also obtained clarification for future groundwater analytical sampling protocol outlined in
his November 29, 2017 response letter regarding recent vinyl chloride (VOC) detections above NCGPSs at
former upgradient background groundwater monitor well MW-50R located at the lined MSW landfill. The
November 29, 2017 letter was prepared by Mr. Lane following his October 4, 2017 meeting and review of a
subsequent correspondence letter documenting the meeting with/from Alamance County. The primary purpose
of the meeting is understood to have been for Alamance County Landfill to obtain clarification from the
NCSWS on the next course of sampling / assessment / corrective action at the lined MSW landfill with regard
the recent vinyl chloride exceedances at monitor well MW-50R. MW-50R was formerly a dual upgradient
background well along with MW-52, however, the MW-50R well was recently replaced with MW-BG (new
dual upgradient background well with MW-52). During the conversation, Mr. Lane clarified that, with regard
to the November 29, 2017 letter, he was only concerned with future Appendix I VOC exceedances above
NCGPSs in groundwater samples collected at lined MSW landfill well MW-50R; and understands that the
metals exceedances at the site will be addressed in a separate Assessment Monitoring / Alternate Source
Demonstration Investigation Report. Mr. Lane was informed that no Appendix I VOCs were detected above
NCGPSs in any of the lined MSW wells (including MW-50R) during the Second Semi -Annual 2017
groundwater monitoring event conducted from October 30 — November 1, 2017. He was also informed that the
groundwater sample collected at MW-50R on October 30, 2017 had a vinyl chloride detection of 0.65J ug/l,
which he agreed did not constitute an exceedance of the NCGPS (NCGPS for vinyl chloride is 0.03 ug/l, which
is well below the NCSWS-SWSL of 1 ug/1 and standard laboratory instrumentation capabilities). Based on this
information, Mr. Lane indicated that Appendix I Detection Monitoring would be allowed to continue at all lined
MSW landfill monitor wells. However, Appendix II Assessment Monitoring groundwater sampling would be
required to be initiated at all lined landfill monitor wells if another VOC exceedance above NCPGSs (including
but not limited to vinyl chloride) occurs at monitor well MW-50R or any other lined landfill well. Mr. Lane
was again informed that landfill gas was being vented from several trenches in the area of MW-50R, and that
the landfill gas was a likely source for the recent detections of vinyl chloride affected groundwater at MW-50R.
However, the actual source of the vinyl chloride had not been positively confirmed to date. Buxton
Environmental, Inc. understands, according to the November 29, 2017 letter from the NCSWS, that Alamance
County is not required to conduct additional assessment or initiate corrective action at this time, since there no
know NCGPS or 2L NCGQS violations beyond the 250' compliance boundary.
On May 29, 2018, the NCSWS issued a memorandum requiring the analysis of 1,4-dioxane, as part of routine
groundwater and surface water monitoring at all landfills after July 1, 2018. The 2L NCGQS for 1,4-dioxane is
3 ug/l. The 1,4-dioxane is required to be analyzed by EPA Method 8260 (VOCs) or EPA Method 8270 (semi-
VOCs) utilizing the SIM procedure, in order to achieve applicable detection limits. In addition, the

memorandum indicated that the use of SWSLs will be discontinued by the NCSWS for all monitored analytical
constituents; and facilities should choose EPA approved analytical methods sufficiently sensitive to quantify the
presence of constituents at or below applicable standards. On May 30, 2018, Mr. Adam Ulishney with the
NCSWS was contacted to discuss the memorandum, and he is aware that there are some 2L NCGQSs that are
currently not reasonably ascertainable with current EPA analytical methods (i.e.: vinyl chloride and others). He
indicated that for the present time, only 1,4-dioxane will be required to be analyzed by the SIM method,
however, SIM analytical methods may be required in the future for other site -specific constituents. Mr.
Ulishney also indicated that the SWSLs had become obsolete, due to current laboratory capabilities to quantify
constituents at much lower concentrations utilizing approved EPA methods.
Former background monitor well MW-50R was requested to be abandoned in the June 3, 2018 First Semi -
Annual 2018, Groundwater, Surface Water and Leachate Monitoring report prepared by Buxton
Environmental, Inc., since this well had been replaced by new dual background well MW-BG; and MW-50R
had not indicated the presence of vinyl chloride above the NCGPS during the three (3) most recent sampling
events. Appendix I metals detected above NCGPSs at MW-50 / MW-50R since background sampling began in
March 2000 are consistent with naturally occurring background conditions (which can be exacerbated by
elevated turbidity conditions). In addition, monitor well MW-50R would require abandonment prior to
construction of the next planned Unit 3 lined MSW landfill lateral expansion. Buxton Environmental, Inc.
understands that the NCSWS authorized the abandonment of monitor well MW-50R along with an immediately
adjacent temporary groundwater monitor well installed during an associated assessment conducted in October
2018 by Municipal Engineering. These two monitor wells were subsequently abandoned.
On July 13, 2018, the NCSWS issued a memorandum based on North Carolina House Bill 573 (approved on
June 25, 2018) indicating that C&D landfills regulated under NCSWS 15A NCAC 13B Rule .0544 could alter
routine groundwater and surface water monitoring frequency from a semi-annual basis to an annual basis.
According to the NCSWS memorandum, annual monitoring is only allowed at stand-alone C&D facilities in
Detection Monitoring; and does not apply to facilities presently in Assessment Monitoring, corrective action or
have documented exceedances of NCGPSs, which will be required to continue semi-annual monitoring. On
July 17, 2018, Mr. Adam Ulishney with the NCSWS indicated that the new policy did not apply to old C&D
landfills permitted under pre-.0544 Rules, however, he indicated that the NCSWS would consider applying this
Rule to old closed C&D landfills on a case -by -case basis in the future.

Volatiles
The method blank associated with batch 39026 had trans- 1,3-dichloropropene detected at a
concentration that was below''/z the LOQ. All samples associated with this method blank that have
detections for trans- 1,3-dichloropropene have been flagged with a "B" qualifier.
The laboratory control sample (LCS) associated with batch 38925 had mutliple compounds recovered
above the acceptance limits. This could potentially result in a high bias on analytical results. There were
no detections for this compound in the samples associated with this batch; therefore, data quality is not
impacted.
The laboratory control sample (LCS) associated with batch 39026 had mutliple compounds recovered
marginally outside of the acceptance limits. Due to the large number of analytes in the LCS, there is a
high statistical probability of a few analytes outside of control limits. Per SW-846 Update V 8000D- 23
Revision 4 July 2014, a number of analytes should be allowed to marginally fail the limits without
requirement for corrective action. The laboratory's SOP allows for 10% of analytes to recover marginally
outside criteria.
The matrix spike/matrix spike duplicate (MS/MSD) associated with sample -017 had trans-1,4-dichloro-2-
butene recovered outside of the acceptance limits. The laboratory control sample (LCS) was recovered
within the required acceptance limits; therefore, this likely demonstrates a matrix effect.

The laboratory control sample (LCS) associated with batch 42623 had sulfate recovered above the
acceptance limits. This could potentially result in a high bias on analytical results. There were no
detections for this compound in the samples associated with this batch; therefore, data quality is not
impacted.
Orthophosphate associated with sample -017 was filtered after the method recommended 15-minute
holding time.
Sample -017 was analyzed outside of analytical holding time for sulfate due to laboratory error.
Sample -017 was received outside of holding time for orthophosphate.

This Report of Analysis contains the analytical result(s) for the sample(s) listed on the Sample Summary
following this Case Narrative. The sample receiving date is documented in the header information
associated with each sample.
All results listed in this report relate only to the samples that are contained within this report. Where
sampling is conducted by the client, results relate to the accuracy of the information provided, and as the
samples are received.
Sample receipt, sample analysis, and data review have been performed in accordance with the most
current approved The NELAC Institute (TNI) standards, the Pace Analytical Services, LLC ("Pace")
Laboratory Quality Manual, standard operating procedures (SOPS), and Pace policies. Any exceptions to
the TNI standards, the Laboratory Quality Manual, SOPS or policies are qualified on the results page or
discussed below.
Pace is a TNI accredited laboratory; however, the following analyses are currently not listed on our TNI
scope of accreditation: Drinking Water: VOC (excluding BTEX, MTBE, Naphthalene, & 1,2-
dichloroethane) EPA 524.2, E. coli and Total coliforms SM 9223 B-2004, Solid Chemical Material: TOC

Coliform Colilert-18.
If you have any questions regarding this report, please contact the Pace Project Manager listed on the
cover page.
Volatiles
The laboratory control sample (LCS) associated with batch 37989 had multiple compounds recovered
marginally outside of the acceptance limits. Due to the large number of analytes in the LCS, there is a
high statistical probability of a few analytes outside of control limits. Per SW-846 Update V 8000D- 23
Revision 4 July 2014, a number of analytes should be allowed to marginally fail the limits without
requirement for corrective action. The laboratory's SOP allows for 10% of analytes to recover marginally
outside criteria.
The laboratory control sample (LCS) associated with batch 37989 had multiple compounds recovered
above the acceptance limits. This could potentially result in a high bias on analytical results. There were
no detections for this compound in the samples associated with this batch; therefore, data quality is not
impacted.
Inorganic non-metals
Sample -002 had sulfate recovered above the instrument's calibration range in the initial analysis. The
sample was analyzed at a dilution outside of the holding time and the detections were confirmed. The
initial results have been reported.
The matrix spike/matrix spike duplicate (MS/MSD) associated with sample -002 had sulfate and chloride
recovered outside of the acceptance limits. The laboratory control sample (LCS) was recovered within the
required acceptance limits; therefore, this likely demonstrates a matrix effect.
