December 2019 Resample Results for Groundwater Well M W-7A4
Dear Mr. Laverty
Groundwater results were received by Duke Energy in December 2019 from the November 2019 required
semi-annual groundwater well sampling event at the Asheville Airport. These results showed anomalous
levels for conductivity, TDS, arsenic, sulfate, cadmium, manganese, nickel & selenium for well MW-7A4.
Duke Energy immediately moved to collect a confirmatory sample from this well for analysis with Pace
Analytical Laboratory with a split sent to the Duke Energy Laboratory. The confirmatory sample was
collected on December 12, 2019. Both labs confirm the elevated conductivity, TDS, arsenic, sulfate,
cadmium, manganese, nickel & selenium while turbidity remains under 10 NTUs. Due to sample dilution
Issues, the resample result for boron from Pace Labs Is less than 2500 ppb while the Duke Lab result for
boron is less than 50 ppb.
As discussed in the field with you at the Asheville Airport on January 13, 2020, well MW-7A4 is located
along Femcliff Park Drive and it is our understanding that underground utility work was performed in the
vicinity of this well since the April 2019 sampling event. Duke Energy will continue semi-annual sampling,
per above -referenced permit, and follow any trends at well MW-7A4. As the above -referenced permit
requires the results on the GW59CCR, both resample results are included but the form Is not signed since
It is not an NPDES permit. Also per the permit, these results are submitted in duplicate to the Central
Processing Unit.
If you have any questions or need any clarification regarding the information provided, feel free to contact
meat iohn.toeoferPduke-eneray.com or at 919-546-7863 at your convenience.
Res p tfully sub'mi/ttt'

Program Comments:
Please review all vendor data for case narratives with explanations of quality control failures and data qualifiers.
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. Certified vendor results and QC qualifiers can be found in the vendor lab final report.
This report shall not be reproduced, except in full, without the written consent of the Analytical Laboratory.
Vendor Data Review Criteria:
This vendor data package has been reviewed at the Duke Analytical Laboratory for the following applicable criteria:
• Required QC samples collected and analyzed
• Required tests performed for all samples
• Vendor Laboratory utilized required test methods for all analyses
• Vendor Laboratory met all requested Reporting Limits (RQ
• QC Results reviewed for outlying recovery values
Case Narrative:
The parent sample and associated field blank collected 12-12-19 were analyzed by PACE Analytical. The duplicate sample
collected the same day was analyzed by the Duke Central Lab tjob order J19120287) at John Toepfer's request.
QC Nate: The ICP sample had tabs diluted due to high internal standard % recoveries due to yttrium (internal standard)
interferences biasing the results low.

Program Comments:
This is a revised report that supersedes the original dated 12-20-19. When reviewing the parent sample date analyzed by PACE
(J19120328), the lab re -ran the duplicate metals sample to double check the results. All results reported initially were consistent
with the reanalysis except for selenium. It was detemlined the initial result was an outlier.
The parent sample of the duplicate sample and the field blank associated with the sampling event were sent to PACE for
analysis. The data will report underjob order J19120328.
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 date 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
