Dear Ms. Moutos:
Duke Energy
McGuire Nuclear Station
12700 Hagers Ferry Road
Huntersville, NC 28078
Duke Energy is providing the result of the first 2023 semi-annual groundwater monitoring for the Duke Energy Carolinas
McGuire Landfill No. 2 (Synthetically Lined), located near Huntersville, North Carolina.
On June 27-28, 2023, groundwater, surface water, and leachate samples were collected in accordance with the McGuire
Landfill No. 2 Sampling and Analysis Plan.
The groundwater sampling field and analytical results are summarized in Table 4. The analytical results for the constituents
are compared to the groundwater standards found in Title 15A NCAC 02L .0202 (2L Standards). Groundwater results with
values that attain or exceed the 2L Standards (or outside of 2L Standard range for pH) are indicated on Table 4 by yellow
highlighting. A summary of the groundwater analytical results that attain or exceed the 2L Standards (or outside of 2L
Standard range for pH) and a preliminary analysis of the cause and significance of such occurrences are presented in
Table 5. In one or more wells, pH measurements were reported outside of the 2L Standard pH range, but no other 2L
exceedances were reported for the June 2023 monitoring event.
The surface water field and analytical results are summarized in Table 6. The surface water analytical results for the
constituents are compared to the surface water standards found in Title 15A NCAC 02B .0211 (2B Standard) for Class C
WS IV waters. No 2B Standards were exceeded during the December 2022 monitoring event. Surface water results with
values that attain or exceed the 213 Standards are indicated on Table 6 by yellow highlighting. A summary of the surface
water analytical results that attain or exceed the 2B Standards and a preliminary analysis of the cause and significance of
such occurrences are presented in Table 7. Mercury was detected in both surface water samples at concentrations that
exceeded the 2B Standard; however, both concentrations were estimates as they fall between the laboratory Method
Detection Limit (MDL) and the laboratory Method Reporting Limit (MRL).
The leachate field and analytical results are summarized in Table 8. The leachate sample was collected from the in -flow
pipe which conveys leachate from the landfill into the leachate pond.
Duke Energy personnel sample designated locations for groundwater, surface water, and leachate at the McGuire Landfill
No. 2 (Synthetically Lined) semi-annually during June and December. The next water quality monitoring event for Landfill
No. 2 is planned for December 2023 with a report of monitoring results to follow.

S&ME Project No. 22350902, Ph. 04
1.0 Background
1.1 Site Description
The Duke Energy Carolinas, McGuire, Landfill #2 (Synthetically Lined)' (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 currently accepts waste.
The landfill was constructed with a high -density polyethylene (HDPE) synthetic liner and leachate collection and
removal system. Leachate and contact stormwater are collected in a synthetically lined leachate collection pond
and pumped to the McGuire Nuclear Station wastewater treatment system. The landfill and surrounding areas are
shown on Figure 1 in Appendix I.
1.2 Hydrologic Setting
The landfill is located south of North Carolina (NC) Highway 73, north of Cashion Road and west of Lindeman
Road as shown on Figures 1 and 2 in Appendix I. Cashion Road runs along a surface water divide, with surface
flow draining to the northwest and the southeast. A surface water drainage feature located northeast of the
landfill drains towards the northwest to an unnamed perennial stream, which discharges into the Catawba River.
The Catawba River is classified as a Class C Water Supply -IV water source, (WS-IV).
1.3 Monitoring Program
As described in the Sampling and Analysis Plan (SAP) dated May 19, 2022, the current monitoring system at the
landfill consists of the following:
Monitoring Wells:
Surface Water Sample Locations:
Leachate Sample Location:
MW-5R2
MW-8
MW-5A
MW-8A
MW-6
MW-9
MW-6A
MW-9A
MW-7R2
MW-10A
MW-7A
SW-1
SW-2
Leachate Pond (in -flow pipe)
' In response to the North Carolina Division of Public Health, Radiation Protection Section, November 17, 2006 letter to Duke
Energy, LLC, Duke Energy offered to indicate the landfill as synthetically lined in reports.
z Replacement monitoring wells MW-5R and MW-7R were installed on October 10th and 11th, 2076 (respectively). The original
MW-5 and MW-7 wells did not consistently produce enough water for groundwater sampling. Each of these replacement wells
were installed deeper than the original wells, with a 15-foot screened interval, per approval from NCDEQ (Approval Replacement
Monitoring Wells MW-5 and MW-7 signed by Elizabeth Werner, Permitting Hydrogeologist dated July 27, 2076).

Semi -Annual Water Quality Monitoring Report — June 2023 Sampling Event
Duke Energy Carolinas, McGuire, Landfill No. 2 .�
(Synthetically Lined) Permit No. 6004-INDUS
S&ME Project No. 22350902, Ph. 04
Monitoring wells were installed as well pairs consisting of one shallow well and one deep well (with the exception
of monitoring well MW-10A, which does not have an accompanying shallow well). Wells with "A" designations
represent the deeper well within each well pair. Wells with "R" designations represent replacement wells. As
designated in the SAP, monitoring well location MW-5R is upgradient and considered to represent background
conditions for the landfill. Well pair MW-9 and MW-9A were installed adjacent to and downgradient from the
leachate pond. The remaining wells were installed adjacent to the landfill review and compliance boundaries. Well
construction information is summarized in Table 1 in Appendix II.
Surface water samples are collected from two locations, SW-1 and SW-2, as shown on Figure 2 in Appendix I.
Surface water sample location SW-1 is collected from an unnamed perennial stream northeast of the landfill and
serves as the background surface water sample location for this monitoring program. Surface water sample
location SW-2 is also collected from an unnamed perennial steam, downstream from surface water sample
location SW-1 and west of the landfill.
The leachate sample is collected from the end of the in -flow pipe, which conveys leachate from the landfill to the
synthetically lined leachate collection pond. The leachate pond resumed permanent operational status in February
2021 after the synthetic liner system was replaced at the end of 2020. The locations of the monitoring wells,
surface water sample locations, and the leachate pond sample location are shown on Figure 2 in Appendix I.

• Duke Energy also provided S&ME (via e-mail correspondence) with the monthly rainfall data for McGuire
Nuclear Station and monthly leachate generation rates (for January 2023 through June 2023). This data
was received by S&ME on September 12, 2023.
2.3 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 June 2023 sampling event, groundwater flow is generally from
the southeast to the north and northwest toward the Catawba River.
2.4 Analytical Results
2.4.1 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 pH range. No other exceedances of 2L Standards were
reported for groundwater samples collected during the June 2023 sampling event.
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 June 2023 sampling event is presented in Table 4 in Appendix
II. A summary of the groundwater analytical results that equal or exceed the 2L Standards and a comparison to
historical concentration ranges are presented in Table 5 in Appendix II.
2.4.2 Surface Water
Laboratory results for the surface water samples (SW-1 and SW-2) 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. It should be noted that Mercury was detected in both surface water samples at
concentrations that exceeded the 2B Standard; however, both concentrations were noted with a 'J' flag by the
laboratory, indicating these concentrations are estimates as they fall between the laboratory Method Detection
Limit (MDL) and the laboratory Method Reporting Limit (MRL). No other constituents exceeded 2B Standards in
the surface water samples collected during the June 2023 sampling event.
A summary of field data parameters recorded prior to sample collection is presented in Table 3 in Appendix II. A
summary of surface water analytical results for the June 2023 sampling event is presented in Table 6 in Appendix
II. A summary of the surface water analytical results that equal or exceed the 2B Standards and a comparison to
historical concentration ranges are presented in Table 7 in Appendix II.

2.4.3 Leachate
The leachate sample was collected from the in -flow pipe which conveys leachate from the landfill into the leachate
pond. A summary of field data parameters recorded at the time of sample collection is presented in Table 3 in
Appendix II. A summary of analytical results for the June 2023 sampling event is presented in Table 8 in
Appendix II. Monthly rainfall data for McGuire Nuclear Station and leachate generation rates (for January 2023
through June 2023) were provided by Duke Energy and are located in Appendix V. S&ME did not evaluate the
leachate analytical results, nor the monthly rainfall and leachate generation data.
2.4.4 Radiological Samples
The results of the radiological analyses for the groundwater, surface water, and leachate samples are presented in
Table 9 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.
2.4.5 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. One field duplicate sample was also collected as a measure of
sampling and analytical precision. Samples for the monitoring wells, surface water locations, and leachate were
submitted to Duke Energy Analytical Laboratories on June 281", 2023.
Per the Pace Analytical Services Case Narrative (Lot Number YF30031) located in Appendix IV, the Laboratory
Control Sample (LCS) exceeded acceptance criteria for acetone and/or 2-butanone (MEK). Each of these analytes
were biased high, and were not detected in any of the groundwater, surface water, or leachate samples.
Mercury was detected in both field blank samples collected on June 2711 and 2811, 2023 at concentrations of 0.04 J
micrograms per liter (ug/L) and 0.05 ug/L, respectively.
Additional QA/QC data, laboratory analyses, and chain -of -custody forms are included in Appendix IV.

QC Note:
Page 1 of 140
Acetone and/or 2-butanone LCS recoveries exceeded the QC limits for the entire set of samples. All were non -detect for these
compounds.
The following samples were re -analyzed outside of the analytical holding time for trans-1,4 dichloro-2-butene due to the failure of
the continuing calibration verification (CCV) and laboratory control sample (LCS): MW-5R, MW-5A, MW-6, MW-6A, MW-10A,
Leachate Pond, and FD-20230627-1.
Reanalysis of the following samples was performed outside of the analytical holding time for acetone and trans-1,4-dichloro-2-
butene due to a LCS failure: FB-20230627-1450 and TB-20230627-0800.
Data Flags & Calculations:
Any analytical tests or individual analytes within a test flagged with a Qualifier indicate a deviation from the method quality
system or quality control requirement. The qualifier description is found at the end of the Certificate of Analysis (sample results)
under the qualifiers heading. All results are reported on a dry weight basis unless otherwise noted. Subcontracted data
included on the Duke Certificate of Analysis is to be used as information only. Certified vendor results can be found in the
subcontracted lab final report. Duke Energy Analytical Laboratory subcontracts analyses to other vendor laboratories that have
been qualified by Duke Energy to perform these analyses except where noted.
Data Package:
This data package includes analytical results that are applicable only to the samples described in this narrative. An estimation of
the uncertainty of measurement for the results in the report is available upon request. This report shall not be reproduced, except
in full, without the written consent of the Analytical Laboratory. Please contact the Analytical laboratory with any questions. The

Due to the large number of spiked analytes, there is a high probability that one or more analytes will recover
outside acceptance limits. The laboratory's SOP allows for 10% of analytes to recover marginally outside
criteria. The following analytes recovered marginally outside LCS/LCSD criteria: trans- 1,4-DichIoro-2-butene
(63%,61 %).
