1.2 Background Information
WCU operated the MSWLF from approximately the 1960s until 1993. Jackson County also disposed of
municipal solid waste at the landfill from approximately the early 1970s through the early 1980s. The
landfill property is approximately 31.5 acres, approximately four acres of which contain the former landfill.
The landfill was closed in accordance with the then applicable North Carolina Department of Environmental
Quality (NCDEQ) closure standards (15A NCAC 13B 0.0510), and a closure letter was issued to WCU by
NCDEQ on September 5, 1995. NCDEQ personnel conducted a facility audit on March 16, 2011 and
determined that semi-annual water quality and landfill gas monitoring at the landfill must be performed in
order for the landfill to be in compliance with the post -closure conditions identified in the 1995 closure
letter.
In response to the audit, a Landfill Gas Investigation Work Plan, which described the preliminary landfill gas
investigation, as well as the 'full' landfill gas investigation, was submitted to NCDEQ on October 19, 2011,
and approved by NCDEQ in a letter dated November 29, 2011. WSP USA Environment & Infrastructure Inc.
(WSP) conducted the preliminary landfill gas investigation in January 2012 using the existing groundwater
monitoring wells. NCDEQ indicated that when funding became available to WCU from the State of North
Carolina, the 'full' landfill gas investigation was to be implemented. WSP has conducted semi-annual water

WCU Closed MSWLF
WSP Project 6252-15-0221
quality monitoring since August 2011 and conducted semi-annual landfill gas monitoring utilizing the
existing groundwater monitoring wells from August 2012 to November 2015 to comply with the post -
closure conditions. The 'full' landfill gas investigation, including the installation of eight permanent landfill
gas monitoring wells, was performed in February 2016. Quarterly landfill gas monitoring is now conducted.
2 FIELD ACTIVITIES
WSP personnel visited the Site on February 6, 2023, to conduct water quality monitoring and on February 7,
2023 to conduct landfill gas monitoring.
2.1 Landfill Gas Monitoring
WSP personnel measured landfill gas at the eight landfill gas monitoring wells (LG-1, LG-2, LG-3S, LG-3D, LG-
4, LG-5, LG-6 and LG-7) at the Site (Figure 2). The landfill gas monitoring wells are screened in the
unsaturated zone and located between the landfill and the Site's property boundary (Table 1). The landfill
gas monitoring wells are fitted with a slip cap and ball valve to allow for measurement of potential landfill
gas. A calibrated gas monitoring instrument, a Landtec GEM 5000, was used to measure atmospheric
barometric pressure, as well as the following landfill gas parameters:
Methane (percent by volume)
Oxygen (percent by volume)
Carbon dioxide (percent by volume)
The initial and stabilized readings for the above parameters were measured and recorded. The Solid Waste
Section's Landfill Gas Monitoring Data Form was used to record measurements and other relevant
information and is provided in Appendix A.
2.2 Water Quality Monitoring
WSP personnel gauged static groundwater levels in the four Site monitoring wells (MW-1, MW-2, MW-3
and MW-4). Water levels were referenced to the top -of -casing at the wells. Depth to water measurements
and water table elevations for the monitoring wells are presented in Table 2.
The monitoring wells were purged and sampled using low -flow purging techniques with a variable -speed
submersible or a peristaltic pump with new polyethylene tubing. The tubing intake was lowered to within
five feet of the bottom of the monitoring wells. The pumping rate was minimized to prevent excessive
drawdown in the well and simulate the groundwater recharge rate, which was monitored using an
electronic water level indicator. Water quality parameters (temperature, pH, specific conductance,
dissolved oxygen, oxidation-reduction potential, and turbidity) were measured using a water quality meter
equipped with a flow -through cell (Table 3). Groundwater samples were collected from the monitoring
wells after the water quality parameters stabilized.
The purge water was discharged to the ground surface in proximity to each well in a manner that precluded
erosion or surface runoff. Copies of the groundwater quality field data records are provided in Appendix B.
The submersible pump was decontaminated by washing the pump and electrical cable in an industrial
detergent and distilled water solution. The pump was then rinsed with distilled water. An equipment blank
sample, EB-1, was collected from the pump discharge by operating the pump in deionized water and
pumping the water into sample containers.

Surface water samples (SW-1 and SW-2) were collected at the approximate location depicted in Figure 2. A
copy of surface water sampling field data records for SW-1 and SW-2 are provided in Appendix B
The water samples were placed in laboratory -supplied containers, labeled with sampling information,
packed in an ice -chilled cooler, and shipped with appropriate chain -of -custody records via overnight
delivery to Waypoint Analytical (a North Carolina -accredited analytical laboratory). The samples were
submitted for analysis of Appendix I volatile organic compounds (VOCs) according to Environmental
Protection Agency (EPA) Method 8260, 1,4-dioxane via EPA Method 8260 SIM (selective ion monitoring),
and Appendix I metals according to EPA Method 6020 (3030C preparation method).
3 RESULTS AND DISCUSSION
The results of the water quality and landfill gas monitoring event are reported in the NCDEQ Environmental
Monitoring Report Form that is provided in Appendix C and summarized in the following sections.
3.1 Landfill Gas
The Site landfill gas monitoring wells were tested for methane, carbon dioxide and oxygen. Refer to the
attached Landfill Gas Monitoring Data Form for the testing results.
Concentrations of methane were not detected in the landfill gas monitoring wells. The regulatory limit for
methane at a MSWLF property boundary is equal to the lower explosive limit of methane (15A NCAC
13B.1627 (d)). The recorded results from the eight landfill gas wells (non -detect) do not exceed this limit
indicating that regulatory limits are not being exceeded at the Site's property boundary.
3.2 Groundwater and Surface Water
The groundwater elevations obtained from the monitoring wells on February 6, 2023, indicate that surficial
groundwater flow is in a northwesterly direction towards the Tuckasegee River, which is consistent with the
flow direction observed during previous monitoring events. A potentiometric surface map (Figure 3) was
prepared using the February 6, 2023, site -wide groundwater elevation data.
Monitoring well MW-1 is the upgradient/background monitoring well. The groundwater analytical results
were compared to the North Carolina Groundwater Classification and Standards (15A NCAC 2L .0202,
amended effective April 1, 2022), which includes applicable interim standards updated April 6, 2018, herein
referred to as the "2L Groundwater Standards", and the EPA Maximum Contaminant Levels (MCLs)
established in the National Primary Drinking Water Regulations, dated May 2009. The surface water
analytical results were compared to the North Carolina Surface Water Quality Standards, Criteria and In -
Stream Target Values (15A NCAC 213, summary tables, dated July 26, 2021), which include EPA's Nationally
Recognized Water Quality Criteria for Aquatic Life and Human Health, herein referred to collectively as the
"Surface Water Standards."
Analytical results from the February 2023 water quality monitoring event are presented in Tables 4 and 5,
and historical analytical results are presented in Tables 6 and 7. The laboratory analytical report is included
in Appendix D.
3.2.1 Appendix I VOCs
Seven Appendix I VOCs were detected or estimated at concentrations above the MDLs in the groundwater
samples. Six Appendix I VOCs were detected or estimated at concentrations above the MDLs in the

WCU Closed MSWLF
WSP Project 6252-15-0221
groundwater sample collected from monitoring well MW-3, as well as the field duplicate groundwater
sample, FD-1, which was collected from monitoring well MW-3. An estimated concentration of toluene was
detected in the groundwater sample collected from monitoring well MW-4. The detected or estimated VOC
concentrations were below their respective 2L Groundwater Standards and EPA MCLs (if established).
Appendix 1 VOCs were not detected or estimated at concentrations above the MDLs in the groundwater
samples collected from monitoring wells MW-1 and MW-2.
Two Appendix I VOCs were detected or estimated at concentrations above the MDLs in the surface water
sample collected from SW-2. The VOC concentrations were below their respective Surface Water Standards,
if established. Appendix I VOCs were not detected above the MDLs in the surface water sample collected
from SW-1.
3.2.2 1,4-Dioxane
An estimated concentration of 1,4-Dioxane was detected above the MDL in the groundwater sample
collected from monitoring well MW-3. The estimated concentration was below its respective 2L
Groundwater Standard and an EPA MCL for 1,4-dioxane has not been established. An estimated
concentration of 1,4-Dioxane was detected above the MDL in the surface water sample collected from SW-
2. The estimated concentration of 1,4-Dioxane was below its respective Surface Water Standard.
3.2.3 Appendix I Metals
Six Appendix I metals were detected and/or estimated above the MDLs in the groundwater samples. One of
the six Appendix I metals (cobalt) was detected at concentrations from samples collected from MW-3 and
the associated field duplicate (FD-1) above the 2L Groundwater Standard. The remaining five Appendix I
metals were detected at concentrations and/or estimated concentrations below their respective EPA MCLs,
if established. Information on each of the metals is presented below.
Barium was detected at concentrations above the MDL, but below the 2L Groundwater Standard and EPA
MCL in the groundwater samples collected from each monitoring well and the field duplicate sample. An
estimated concentration of barium was detected above the MDL in the equipment blank.
Chromium was detected at concentrations above the MDL, but below the 2L Groundwater Standard and
EPA MCL in groundwater samples collected from MW-1 and MW-3 (including duplicate FD-1). Chromium
was not detected above the MDL in the remaining groundwater samples or the equipment blank.
Cobalt was detected or estimated at concentrations above the MDL in the groundwater samples collected
from MW-1, MW-3 (including duplicate FD-1), and MW-4. The concentrations of cobalt detected from MW-
3 and FD-1 exceeded the 2L Groundwater Standard of 1.0 µg/L. An EPA MCL is not currently established for
cobalt. Cobalt was not detected above the MDL in the groundwater sample from MW-2 or the equipment
blank.
Copper was estimated at a concentration above the MDL, but below its 2L Groundwater Standard and EPA
MCL in the groundwater sample collected from the site's background/upgradient monitoring well MW-1.
Copper was not detected above the MDL in the other groundwater samples or the equipment blank.
Nickel was detected or estimated at concentrations above the MDL, but below its respective 2L
Groundwater Standard, in the groundwater samples collected from MW-1, MW-2, and MW-3 (including
duplicate FD-1). An EPA MCL is not currently established for nickel. Nickel was not detected above the MDL
in MW-4 or the equipment blank.

March 29, 2023
Zinc was detected at estimated concentrations above the MDL, but below the 2L Groundwater Standard in
the groundwater sample collected from MW-3 (including duplicate FD-1). Zinc was detected at an
estimated concentration above the MDL in the equipment blank and laboratory blank.
Concentrations of five Appendix I metals were detected or estimated above the MDL in the groundwater
sample collected from the Site's background/upgradient monitoring well MW-1.
Concentrations of Appendix I metals in groundwater samples have generally been lower than historical
concentrations with less exceedances above applicable Standards since low -flow purging/sampling has
been implemented. Low -flow purging/sampling techniques will continue to be used for the next semi-
annual water quality monitoring event.
Six Appendix I metals were detected or estimated at concentrations above the MDLs in the surface water
samples collected from SW-1 and SW-2. The metal concentrations were below their respective Surface
Water Standards, if established. Zinc was also detected above the MDL in the laboratory blank.
