1.0 Background
1.1 Site Description
The Duke Energy Carolinas, McGuire, Landfill #1 (Unlined)' (hereafter, landfill) is located at the McGuire Nuclear
Station in Mecklenburg County, North Carolina. The landfill is permitted under North Carolina Department of
Environmental Quality (NCDEQ) Solid Waste Permit No. 6004-INDUS and is closed and no longer accepts waste.
The landfill and surrounding areas are shown on Figure 1 in Appendix I. The approximate limit of waste is shown
in Figures 2 and 3 in Appendix I.
1.2 Hydrologic Setting
The closed landfill is located south of North Carolina (NC) Highway 73, east of the Catawba River, and northwest
of Cashion Road as shown on Figures 1 and 2 in Appendix I. Cashion Road runs along a topographic divide with
topography sloping away from the road to the northwest and to the southeast. There is one surface water
drainage feature north of the landfill that drains northwest to the Catawba River as depicted on Figure 2 in
Appendix I. The Catawba River is classified as a Class C Water Supply -IV source (WS-IV).
1.3 Monitoring Program
As described in the Sampling and Analysis Plan (SAP) dated May 13, 2022, the current monitoring system at the
landfill consists of the following:

Semi -Annual Water Quality Monitoring Report — July 2023 Sampling Event
Duke Energy Carolinas, McGuire, Landfill No. 1 �r
(Unlined) Permit No. 6004
S&ME Project No. 22350902, Ph. 02
Monitoring wells were originally installed as well pairs, consisting of one shallow well and one deep well (with the
exception of monitoring well MW-13D, which is accompanied by a bedrock well rather than a shallow well).
Shallow wells were installed with screened intervals set to bracket the water table at the time of installation. Deep
wells were constructed so that the bottom of the screen is located within residual soils just above auger refusal
and are designated with "D" to represent the deeper well within each well pair. Wells designated with "BR"
represent wells constructed so that the bottom of the screen is located within fractured bedrock.
Monitoring wells MW-4R and MW-4DR ("R" designation indicates replacement wells) were installed in 2013 near
the landfill review boundary to replace wells MW-4 and MW-4D, which are approximately 15 feet outside of the
limits of waste for the landfill. At the request of NCDEQ Solid Waste Section (NCDEQ-SWS), monitoring wells MW-
4 and MW-41D continue to be sampled along with the replacement wells.
It should be noted that six deep and bedrock monitoring wells (MW-3BR, MW-4BR, MW-4BRR, MW-11 BR, MW-
13D, and MW-13BR) were installed in late 2020 as part of a site characterization study. This Semi -Annual Water
Quality Monitoring Report (WQMR) for the July 2023 Sampling Event at the landfill is the third WQMR to include
these six additional wells as part of the sampling regime. Monitoring well construction information is summarized
in Table 1 in Appendix II and monitoring well locations are shown on Figure 2 in Appendix I.
Surface water sample location SW-1 is collected from the unnamed stream (north of the landfill), upstream of the
confluence with the surface water drainage feature that ultimately discharges to the Catawba River as shown on
Figure 2 in Appendix I. SW-1 is the designated background sampling location for this monitoring program.
2.0 Methods
2.1 Sampling and Analysis Methods
Groundwater and surface water sampling activities were performed by Duke Energy Groundwater Science Group
(Duke Energy Carolinas Field Certification #99046001), in general accordance with the North Carolina Solid Waste
Management Guidelines. Copies of the July 2023 field sampling forms are included in Appendix III. The
parameters and constituents reported were selected in accordance with the SAP and the NCDEQ Division of Waste
Management, Solid Waste Section Guidelines. Groundwater and surface water samples were analyzed by the Duke
Energy Analytical Laboratory (North Carolina Laboratory Certification #248), Pace Analytical Services (North
Carolina Laboratory Certification #329), and EnRad Laboratories. The laboratory reports and chain -of -custody
forms are included in Appendix IV.
2.1.1 Groundwater and Surface Water

S&ME Project No. 22350902, Ph. 02
• Reviewed the laboratory analytical results and the Electronic Data Deliverables (EDDs) provided by Duke
Energy for the samples noted above.
• Developed a shallow groundwater contour map and calculated groundwater flow velocities using survey
data and groundwater levels measured by Duke Energy Groundwater Sciences Group.
3.0 Results
3.1 Site Groundwater Flow
Shallow groundwater surface contours and groundwater flow direction in the vicinity of the landfill are shown on
Figure 3 in Appendix I. These contours were developed using the depth to groundwater measurements in the
shallow wells on the date of sampling and top of well casing elevations. Calculated groundwater flow velocities
are presented on Table 2 in Appendix II.
Based on groundwater elevations calculated for the July 2023 sampling event, groundwater flow is generally from
the southeast to the northwest toward the Catawba River.
3.2 Analytical Results
3.2.1 Groundwater
Laboratory results for groundwater samples were compared to the Title 15A NCAC Subchapter 2L Standards (2L
Standards) to evaluate compliance with NCDEQ groundwater quality standards. In one or more wells, pH
measurements were reported outside of the 2L Standard range. Concentrations greater than their respective 2L
Standards were reported in one or more wells for the following constituents: methylene chloride, lead,
tetrachloroethylene (PCE), trichloroethylene, sulfate, and vinyl chloride.
The concentrations greater than the 2L Standard (with the exception of pH) were detected in MW-3, MW-313R,
MW-4, MW-4D, MW-4BR, MW-4R, and MW-4BRR. It should be noted that MW-4, MW-4D, and MW-4BR are
located adjacent to the landfill limits of waste boundary; while MW-3, MW-3BR, MW-4R, and MW-4BRR are
located adjacent to the landfill review boundary.
A summary of field data parameters recorded prior to sample collection is presented in Table 3 in Appendix II. A
summary of groundwater analytical results for the current sampling event is presented in Table 4 in Appendix II.
5 Please note that periodically, shallow monitoring well MW-72 is not used to produce groundwater contours. MW-72
was used to produce groundwater contours for the January 2023 and July 2023 Sampling Events. Historically, MW-72
has experienced water level elevation fluctuations not typical of normal seasonal variations. Duke Energy is currently
evaluating the water level data and the need for future abandonment and/or replacement.

3.2.2 Surface Water
Laboratory results for the surface water sample (SW-1) were compared to the Title 15A NCAC Subchapter 2B
Standards (213 Standards) for Class C WS-IV waters to evaluate compliance with NCDEQ surface water quality
standards. No constituents exceeded 2B Standards in the surface water sample SW-1 collected during the July
2023 sampling event. A summary of field data parameters recorded prior to surface water sample collection is
presented in Table 3 in Appendix II. A summary of surface water analytical results for the July 2023 sampling
event is presented in Table 6 in Appendix II.
3.2.3 Radiological Samples
The results of the radiological analyses for groundwater and surface water samples are presented in Table 7 in
Appendix II. A copy of the laboratory report has been submitted to the North Carolina Department of Health and
Human Services Radiation Protection Section for reference and is also included in this report in Appendix IV.
S&ME did not evaluate this data.
3.2.4 Quality Assurance / Quality Control
Field -performed quality assurance and quality control (QA/QC) consisted of the collection and analysis of two field
blanks (one on each day of sampling) to evaluate if contamination was imparted to the samples by the sample
container, preservative, or other exogenous sources. Two field duplicates were also collected (one on each day of
sampling) as a measure of sampling and analytical precision. Samples for the monitoring wells and surface water
location were submitted to the Duke Energy Analytical Laboratories on July 261", 2023.
One trip blank (collected on July 251"- 2023) was transported with the Volatile Organic Compound (VOC) samples
to evaluate the effects of shipping and laboratory sources of contamination. No constituents were detected at
concentrations above the laboratory Method Reporting Limit (MRL) in the trip blank sample.
Select samples were diluted, as is normal laboratory practice, to bring samples within the calibrated range of the
analysis. Specifics regarding the samples that were diluted, including the dilution amount, are reported in the lab
report. Additional QA/QC data, laboratory analyses, and chain -of -custody forms are included in Appendix IV.
