1.0 Introduction
Groundwater and surface water compliance monitoring was completed between June 22 and
July 6, 2023, at the C&D Landfill, Inc. Construction and Demolition Debris Landfill (C&D Landfill)
near Greenville, North Carolina. The monitoring event satisfies requirements of the compliance
monitoring program under Solid Waste Permit No. 74-07 and Solid Waste Regulations 15A
NCAC 13B .0544, with the current monitoring network configuration meeting requirements of
15A NCAC 13B .0546. The following report summarizes sampling procedures, field and
laboratory results, and groundwater characterization as required by North Carolina Department
of Environmental Quality (NCDEQ), Division of Waste Management (DWM), Solid Waste
Section (SWS) Regulations. The monitoring conducted for this report included the wells and
parameters listed under the semi-annual frequency column in the table on page 5 of the SWS
approved Water Quality Monitoring Plan, Phases 1, 2 and 3, C&D Landfill, Inc., Greenville,
North Carolina (Smith Gardner, March 2022). The NCDEQ Environmental Monitoring Reporting
Form is included with this report.
Since the December 2022 monitoring event, piezometers PZ-10, PZ-11, and PZ-11 D
(downgradient of future Phase 3) were converted to groundwater monitoring wells MW-18, MW-
19, and MW-19D, respectively. Well MW-19D is used for water level data only at this time.
In addition to groundwater and surface water sampling, landfill gas monitoring was conducted in
March and June 2023 by C&D Landfill personnel in accordance with the approved Landfill Gas
Monitoring Plan, Phases 1, 2 and 3, C&D Landfill, Inc., Greenville, North Carolina (Smith
Gardner, March 2022) to satisfy requirements provided in the facility's Solid Waste Permit.
Landfill gas monitoring results are also summarized herein.
The facility contains two unlined C&D landfill units. Phase 1 has ceased accepting waste and
entered final closure in late 2022, and Phase 2 is currently accepting waste. The Facility was
developed in two non-contiguous footprints, Phases 1 and 2 approximately midway between US
264, a localized topographic divide, and Grindle Creek. The phases became operational in May
2001 and August 2009, respectively. Phase 1 was the regional repository for flood -damage
debris after Hurricane Floyd in 1999. Phase 2 was a staging area, where flood -debris was
C&D Landfill, Inc. 4 Semi -Annual Compliance Monitoring Report
Greenville, North Carolina October 2023

stored temporarily. Both areas were previously used for agricultural purposes. A former
railroad corridor traverses the site, including beneath a portion of the Phase 2 footprint.
2.0 Geology and Hydrogeology
Historical literature and available geologic maps indicate that the C&D Landfill is located within
the North Carolina Coastal Plain Physiographic Province. The Coastal Plain is characterized as
an eastward thickening wedge of sedimentary units that alternate between sandy aquifers and
clayey aquitards. Information taken from The Geologic Map of North Carolina, 1985, shows that
the C&D landfill is underlain by the Yorktown Formation, which is described as "fossiliferous clay
with varying amounts of fine-grained sand, silty sand, sandy silt, silty clay, and blueish gray shell
material".
Local groundwater in the uppermost aquifer flows through unconsolidated sediments. Recharge
occurs generally in the northern portion of the site. Groundwater flows generally south and
southwest where it discharges into tributaries of Grindle Creek. The groundwater potentiometric
surface generally reflects surface topography, with mounding beneath the Phase 1 and 2 landfill
footprints. Local conditions are considered typical for the Coastal Plain region. Groundwater
depths generally range from three feet to 13 feet below ground surface (bgs) across the facility.
There are minor seasonal variations in the flow pattern, but overall, the flow direction is
consistent.
3.0 Field Methods
3.1 Groundwater and Surface Water Monitoring
Groundwater and surface water samples were collected for the June 2023 sampling event in
accordance with the approved site water quality monitoring plan, as noted above. The following
compliance monitoring points (wells) were sampled for this event as outlined in the semi-annual
monitoring network schedule included in the plan: MW-1 S (upgradient of Phase 1); MW-2S; MW-
3A; MW-4; MW-5; MW-6; MW-7; MW-8; MW-9A and MW-17 (upgradient of Phase 2); MW-10;
MW-11; MW-12S; MW-13; MW-14S; MW-15; MW-18; and MW-19. It should be noted that the
deep wells were not scheduled for sampling during this monitoring event. Well Inspections
C&D Landfill, Inc. 5 Semi -Annual Compliance Monitoring Report
Greenville, North Carolina October 2023

Checklists are provided as Appendix A. The monitoring network also includes four surface
water locations (SW-1 through SW-4). Surface water locations SW-1 and SW-2 were unable to
be sampled during this monitoring event due to the locations being dry. Sampling locations are
shown on Figure 1.
Sampling methods followed the protocol outlined in the North Carolina Water Quality Monitoring
Guidance Document for Solid Waste Facilities (NCDEQ, DWM, SWS) and the aforementioned
approved site water quality monitoring plan. Prior to well purging for sample collection,
monitoring wells were gauged to determine the depth to groundwater. Groundwater depths and
elevations from this monitoring event, as well as well construction details, are presented in
Table 1.
Prior to sample collection, each well was purged and field water quality parameters were
measured during the process using a calibrated YSI meter that including temperature, pH,
specific conductivity, dissolved oxygen (DO), and oxidation-reduction potential (ORP) until the
parameters stabilized. Turbidity was measured using a separate turbidity meter. Stabilized field
parameter measurements are provided in Table 2.
Groundwater samples were collected following low -flow methods with a peristaltic pump and
new polyethylene tubing. The samples were collected in laboratory prepared containers for the
specified analytical parameters discussed below. Groundwater samples and quality control
samples were properly preserved, placed on ice and transported to a North Carolina certified
laboratory within the specified hold times for each analysis.
Surface water samples were collected from locations SW-3 and SW-4 using a peristaltic pump
and new polyethylene tubing. The water samples were transferred directly into laboratory
prepared sample containers.
Groundwater samples were collected in laboratory containers provided by Waypoint Analytical.
Groundwater samples were analyzed for the following in accordance with the aforementioned
semi-annual sampling frequency listed in the site's groundwater monitoring plan:

Groundwater sample MW-8 was also analyzed for pesticides and PCBs by EPA Method 8081 B
due to the presence of Delta-BHC at a concentration above the laboratory Method Reporting
Limit (MRL) in December 2022. Groundwater samples MW-3A, MW-8, MW-10, MW-12S, MW-
14S, MW-18, and MW-19 were also sampled for sulfide and cyanide, and groundwater samples
MW-5, MW-7, MW-11, and MW-17 included sampling for sulfide.
Surface water samples SW-3 and SW-4 were analyzed for the following:
• Appendix I VOCs, plus tetrahydrofuran and 1,4-dioxane, by EPA Method 8260D;
Appendix I metals by EPA Method 200.8; and
• TDS.
Groundwater samples were transported to the laboratory on ice under chain -of -custody
protocols. Analytical results were compared to the 15A NCAC 02L .0202 Groundwater Quality
Standards or Interim Maximum Allowable Concentrations (hereinafter referred to as the `21-
Standards'). Surface water analytical results were compared to the 15A NCAC 02B Surface
Water Quality Standards (hereinafter referred to as the `21B Standards'). Groundwater Sample
Collection Records are provided in Appendix B.
3.2 Landfill Gas Monitoring
Nineteen landfill gas monitoring points (GP-1 through GP-5, GP-10, GP-11, SG-6, SG-7, SG-8,
SG-12 through SG-20) were monitored by C&D Landfill personnel in March 2023. Six landfill
gas points (GP-1 through GP-4, GP-10, and GP-11) were monitored by C&D Landfill personnel
in June 2023. The aforementioned current approved landfill gas monitoring plan (March 2022)
has reduced the number of monitoring locations to the six identified above for the June event.

VOCs were detected above the laboratory Method Detection Limit (MDL) in either sample.
4.2 Surface Water Results
Surface water organic analytical results indicated the presence of acetone, tetra hydrofuran,
toluene, and 1,4-dioxane in sample SW-3, and toluene and 1,4-dioxane in sample SW-4. The
concentrations of these compounds are well below their respective 2B Standards. As noted
above, SW-1 and SW-2 were unable to be sampled during this sampling event due to the
locations being dry.
C&D Landfill, Inc. 9 Semi -Annual Compliance Monitoring Report
Greenville, North Carolina October 2023

Inorganics detected above the 2B Standard only included lead for chronic toxicity detected in
sample SW-3. This detection was "J" qualified (i.e., an estimated value that is less than the MRL
and greater than or equal to the MDL)
No other analytes were detected in surface water samples that exceeded their respective 2B
Standard. Surface water analytical results are summarized in Table 4 and the laboratory
analytical report is provided in Appendix D.
4.3 Landfill Gas Results
As noted in Section 3.2, quarterly landfill gas monitoring events were conducted by C&D Landfill
personnel on March 23, 2023 and June 30, 2023. Landfill gas was measured at 19 landfill gas
monitoring locations in March and six locations in June (reduction based on the current
approved Landfill Gas Monitoring Plan (March 2022)).
All monitoring locations exhibited 0% LEL during the reporting period. Hydrogen sulfide gas
was also not detected at any location. DWM Landfill Gas Monitoring Data Forms for the
reporting period are provided in Appendix C.
5.0 Groundwater Characterization
A water table contour map was prepared from the well gauging measurements collected on
June 22, 2023 as shown on Figure 1. According to the figure, shallow groundwater flows
generally south and southwest toward tributaries of Grindle Creek as historically observed.
Horizontal groundwater flow velocities were calculated using the equation V = KI/ne where:
V = estimated horizontal velocity,
K = hydraulic conductivity (from historical monitoring reports),
I = estimated shallow hydraulic gradient,
ne = estimated effective porosity (from historical monitoring reports).
Calculated estimated shallow groundwater velocities ranged from 0.0016 ft/day at MW-11 to
0.043 ft/day at MW-3A, averaging 0.019 feet/day, as shown on Table 5.

additional source contribution during the reporting period. A review of historical data shows the
presence of organochlorides, and in addition to continued detection of vinyl chloride, indicates
that reductive dichlorination via natural attenuation may be occurring at the Site. As directed by
the SWS (July 6, 2023 letter), a monitored natural attenuation (MNA) evaluation for site
groundwater is being conducted and will be submitted to the department in December 2023.
Six metals, sulfate, and TDS were detected in monitoring wells above their 2L Standards during
this monitoring event. As directed by the SWS (July 6, 2023 letter), an alternate source
demonstration (ASD) for site groundwater is being conducted and will be submitted to the
department in December 2023
No organic compounds were detected in surface water samples above 2B Standards. The only
inorganic compound detected above its 2B Standard was lead in SW-3, which was "J" qualified
(i.e., an estimated value that is less than the MRL and greater than or equal to the MDL).
Surface water sample locations SW-1 and SW-2 could not be sampled due to dry conditions.
Semi-annual groundwater and surface water monitoring will continue at the site with the next
event scheduled for December 2023. The monitoring will include the wells and parameters
listed under Semi -Annual Frequency in the approved water quality monitoring plan, with the
addition of polyfluoroalkyl substances (PFAS) analysis as part of the groundwater sampling as
required by the SWS.
All landfill gas monitoring locations exhibited 0% LEL during the reporting period. Hydrogen
sulfide gas was also not detected at any location.
C&D Landfill personnel will continue with quarterly landfill gas monitoring at the site with the
next two events scheduled for September and December 2023. The six monitoring points
specified in the approved landfill gas monitoring plan will continue to be evaluated in addition to
the two additional monitoring points located northeast and northwest of the Phase 3 currently
under construction. Monitoring at these two additional locations (LFG-3-1 and LFG-3-2) will be
initiated when Phase 3 begins to accept waste debris.
