This semiannual report pertains to the Duke Energy Carolinas, LLC (Duke Energy) Marshall
Steam Station (Marshall, Site) Dry Ash Landfill and documents the results of the August 2022
Industrial Landfill (Landfill; Permit No. 1804-INDUS) groundwater monitoring event.
1.1 Site and Landfill Information
Duke Energy owns and operates Marshall Steam Station, located at 8320 INC Highway 150E in
Terrell, Catawba County, North Carolina (Figure 1).
The North Carolina Department of Environmental Quality (NCDEQ) Division of Waste
Management (Division) issued a permit to operate the Dry Ash Landfill in December 1983. The
Landfill consists of the following disposal areas:
• Fly ash disposal (two Phases): Phase I —14.5 acres (approximate) and Phase II — 46.2
acres (approximate).
o Excavation of Phase I was completed in August 2022.
• Asbestos disposal: 6.9 acres (approximate); permitted December 1987
• Construction and demolition (C&D) debris disposal: 2.75 acres (approximate); permitted
October 17, 1989.
These landfills were constructed as unlined landfills and are closed with soil covers and
groundwater monitoring.
1.2 Hydrogeologic Setting
The Landfill site is located within the Piedmont physiographic province (Piedmont). Piedmont
bedrock primarily consists of igneous and metamorphic bedrock. The fractured bedrock is
overlain by a mantle of unconsolidated material known as regolith. The regolith includes, where
present, the soil zone, a zone of weathered, decomposed bedrock known as saprolite, and
alluvium. Saprolite, the product of chemical and mechanical weathering of the underlying
bedrock, is typically composed of clay and coarser granular material up to boulder size and may
reflect the texture of the rock from which it was formed. The weathering product of granitic
rocks may be quartz -rich and sandy -textured, whereas rocks poor in quartz and rich in feldspar
and other soluble minerals form a more clayey saprolite (S&ME, 2020).
Groundwater at the Site typically occurs in three interconnected flow zones. The shallowest
groundwater flow zone — the surficial flow zone — occurs in the residual soil and/or the upper
section of saprolite. Beneath the surficial flow zone, the transition zone flow zone occurs in the
lower portions of the saprolite and partially weathered bedrock and is the most permeable part
of the Site hydrogeologic system. Bedrock underlies the transition zone and comprises the least
permeable flow zone of the Site hydrogeologic system, where groundwater flow occurs

predominantly along fractures, joints, and faults. Groundwater is usually first encountered in
the surficial flow zone.
1.3 Landfill Semi -Annual Monitoring Program
The initial Sample and Analysis Groundwater Plan (SAP) (Altamont Environmental, 2012) has
been revised over time to incorporate changes. The August 2022 sampling event and this
Semiannual Water Quality Monitoring Report comply with SAP, Revision 1 (S&ME, 2020)
submitted to the Division on August 24, 2020. The Landfill semi-annual monitoring program,
described in detail in the SAP, consists of eight groundwater monitoring locations. Monitoring
well MW-4 is designated as a background well for the Landfill. Monitoring wells OB-2 (MW-6)
and OB-3 (MW-7) are designated as water level measurement only wells and are not sampled.
A summary of monitoring well construction information is presented in Table 1 and analytical
parameter coverage for the Landfill semi-annual groundwater monitoring program is
summarized in Table 2. Two groundwater monitoring locations have since been abandoned.
Monitoring well MW-5 was abandoned in December 2020 due to construction for the Site's
water redirect project, and observation well OB-1 was abandoned in April 2021 due to
excavation of Phase I. The existing groundwater monitoring locations are summarized in
Table 3 and shown on Figure 2.

2.0 METHODS
2.1 Sampling and Analysis Methods
Groundwater sampling was performed by Pace Analytical Services personnel (Pace Analytical
North Carolina Field Certification #5342) on August 10, 2022, in accordance with the North
Carolina Solid Waste Management Guidelines. Copies of the field sampling forms are included
in Appendix A. Duke Energy Analytical Laboratory (North Carolina Laboratory Certification
#248) analyzed the reported parameters and constituents. The laboratory report and chain -of -
custody forms are included in Appendix B.
The samples were analyzed for the list of parameters and constituents outlined in the SAP and
guidance from the NCDEQ Division of Waste Management, Solid Waste Section (SWS). The
monitoring parameters, along with the U.S. Environmental Protection Agency (USEPA) Solid
Waste (SW)-846 analytical methods, 15A NCAC 02L .0202(g) Groundwater Quality Standards
(02L)) are present in Table 2.
2.2 Regulatory Criteria
Evaluation of the semiannual monitoring analytical results are compared to the following
regulatory criteria:
Groundwater
• 02L
2.3 Statement of Work
The following tasks were completed for semiannual water quality monitoring:
• Groundwater levels and samples were collected on August 10, 2022.
• Reviewed the laboratory analytical results pertaining to the parameters listed in Table 2.
• Compared groundwater analytical results to 02L standards and historical concentration
ranges.
• Developed generalized groundwater surface contour maps using groundwater elevation
data.
• Calculated groundwater flow velocity based on groundwater elevations at wells
perpendicular to groundwater flow.
• Converted the laboratory provided electronic data deliverable (EDD) to the format
requirements of the NCDEQ DWM EDD template and submitted copies of the EDDs to
the NCDEQ DWM with this report.
• Prepared and submitted this Semiannual Water Quality Monitoring Report

Terrell, North Carolina
3.1 Site Groundwater Flow
Generalized groundwater elevation contours and groundwater flow direction arrows in the
vicinity of the Dry Ash Landfill are shown on Figure 3 for the surficial flow zone. These contours
were developed by calculating groundwater elevations in each monitoring well using the depth -
to -water -level measurements taken during the August 2022 monitoring event. The water level
in MW-6(OB-2) has significantly decreased since the previous report resulting from
groundwater corrective action related to the Ash Basin; the water level was below the pump
and was not measurable. Similarly, the water level in MW-1 remains below the pump as well. In
addition, water -level measurements from nearby groundwater monitoring wells included in
other Site groundwater monitoring programs were used. Depth -to -water measurements and
calculated groundwater elevations are presented in Table 1. The calculated groundwater flow
velocity for the Phase II area is presented in Table 4; groundwater flow velocity was not
calculated for the Phase I area because the water level in MW-1 was below the pump.
Calculated groundwater elevations based on depth -to -water measurements gauged during the
August 2022 monitoring event indicate groundwater at the Landfill generally flows to the south
and southeast towards Lake Norman, consistent with historical Site observations.
3.2 Analytical Results
Analytical results, field data and reference comparisons discussed below are summarized in
Table 5 and Table 6. Sample locations are depicted on Figure 2.
Groundwater Results
Field and analytical results for the collected downgradient and background groundwater
samples are presented in Table 5. MW-1 ) was not able to be sampled because the water level
was below the pump. Groundwater analytical results are compared with 02L. Constituent
concentrations equal to or greater than their 02L include pH, boron, cobalt and selenium in one
or more wells and are noted in Table 5 by bold font. The laboratory analytical reports are
included as Appendix B. A summary of the four groundwater field and analytical results that are
equal to or greater than 02L (pH, boron, cobalt, and selenium) with a comparison to historical
data are presented in Table 6.
Time versus concentration plots of the locations where concentrations are greater than 02L are
presented in Appendix C. These demonstrate the historical concentrations at these locations
and their behavior over time. The following observations were made:
• pH at MW-2, MW-3, and MW-4 are generally stable.
• Boron concentration trend at MW-2 is stable or slightly decreasing.
• Cobalt concentrations at MW-3 are relatively stable.
• Selenium concentrations at MW-2 are increasing.

3.3 Quality Assurance/Quality Control
Field -performed quality assurance and quality control (QA/QC) consisted of the collection and
analysis of a field blank to evaluate if contamination was imparted to the samples by the
sample container, preservative, or other exogenous sources. A field duplicate sample was also
collected to estimate sampling and laboratory precision.
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 B.

The questions on this checklist refer to basic review of laboratory analytical reports for completeness and accuracy of data. Any responses requiring follow up action with the analytical lab or field personnel must
be noted in the summary section at the end of this form before the data can be approved for use by technical leads.
Lab Qualifiers:
J (Duke) -Analyte detected above the MDL, but below the RL; analyte concentration should be considered an estimate.
U (Duke) -Analyte was analyzed for, but not detected above the MDL.
Validation Qualifiers:
R- Result is unusable. The sample result is rejected due to serious deficiencies in meeting quality control criteria; the analyte may or may not be present in the sample.
J - Value is estimated. The result is below the reporting limit or potentially biased based on data validation.
U-Analyte was analyzed form but not detected above the minimum detectable concentration (MDC) or method detection limit (MDL).
B -Target analyte detected in the method blank an in the sample at a concentration less than 10x the blank concentration.
• MW-1 not collected due to dry well.
• Calcium (0.014 mg/L) was detected in the Equipment Blank; Calcium was not detected in the samples at concentrations less than lox the blank concentration.
• Nitrate (0.03 mg/L) and Nitrate as N (0.01 mg-N/L) were detected in the Field Blank; Nitrate and Nitrate as N were not detected in the samples at concentrations less than 10x the blank
concentrations.

QUALIFIERS
Project: J22070248 MSS LF
Pace Project No.: 92620222
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL -Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.
RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis of Acrolein and Acrylonitrile by EPA
Method 8260.
N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method 8270. The result reported for
each analyte is a combined concentration.
Reported results are not rounded until the final step prior to reporting. Therefore, calculated parameters that are typically reported as
"Total" may vary slightly from the sum of the reported component parameters.
Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes.
TN -The NELAC Institute.
