Reference: Supplemental Surface Water PFAS Sampling (2"d Quarter 2023)
Charlotte Douglas International Airport
5501 Josh Birmingham Parkway,
Charlotte, North Carolina
S&ME Project No. 22350274
Dear Mr. Eller:
S&ME, Inc. (S&ME) submits this letter report summarizing supplemental Per- and Polyfluoroalkyl Substances
(PFAS) sampling activities conducted at the Charlotte Douglas International Airport (CLT) on June 12, 2023. This
letter documents the field activities performed and presents the laboratory analytical data of surface water quality
from selected outfalls sampled around the perimeter of the CLT property. The sampling services were performed
in general accordance with the Agreement for Professional Services with the City of Charlotte c/o Aviation
Department contract No. 2022000941 dated August 12, 2022 ("the Agreement").
Project Background
Based on information provided to S&ME on May 5, 2023, we understand that CLT is required to conduct quarterly
National Pollutant Discharge Elimination System (NPDES) monitoring. S&ME completed the second quarter 2023
NPDES discharge sampling on June 12, 2023, and issued the report to CLT on July 25, 2023. In addition to the
quarterly NPDES sampling, CLT requested the collection of additional samples to be submitted for laboratory
analysis for PFAS from select outfalls 001, 004, F, H, and K. A sample location map depicting the outfalls as
provided by CLT is included as Figure 2.
Summary of Sampling Activities
On June 12, 2023, S&ME personnel visited CLT and collected grab surface water samples from outfalls 001, 004, F,
H, and K for laboratory analysis for PFAS by Draft EPA Method 1633 via isotope dilution. The samples were
collected in general accordance with the sampling protocols established by the Michigan Department of
Environmental Quality (MDEQ). North Carolina regulatory authorities have not issued or promulgated standard
surface water sampling practices for PFAS.
Outfall surface water samples were collected in laboratory -provided sample containers, labeled with site
identification (location, sample time, requested analysis, etc.), recorded on a laboratory provided chain -of -custody,

and placed in a cooler with ice. The samples were shipped via Fed Ex under chain -of -custody protocols to Enthalpy
Analytical in Wilmington, North Carolina on June 12, 2023.
Analytical Results
The analytical results indicated the presence of PFAS in the samples collected from Outfall 4 and Outfall H, as
follows:
Outfall 4:
Perfluoro-n-hexanoic acid (PFHxA) — 10.9 nanograms per liter (ng/L) or parts per trillion (ppt)
Outfall H:
Perfluoropentanoic Acid (PFPeA) — 47.5 ng/L
PFHxA — 41 ng/L
Perfluorohexanesulfonic acid (PFHxS) — 44.9 ng/L
Perfluorooctanesulfonic acid (PFOS) — 84.5 ng/L
1 H, 1 H, 2H, 2H-perfluorooctane sulfonic acid (6:2 FTS) — 186 ng/L
It should be noted that the laboratory analyzed the samples using a lower sample volume due to matrix
interference from particulate matter present in the samples. Due to the lower sample volume, the laboratory
Limit of Quantifications (LOQs) were elevated for the five primary samples and duplicate sample.
The analytical results from the laboratory analysis are summarized in the attached Table 1. A radar plot showing
the relative distribution for PFAS compounds detected above the LOQs (PFPeA, PFHxA, PFHxS, PFOS and 6:2 FTS)
using the data from Outfall H is provided as Chart 1 for comparison purposes in subsequent sampling events. The
laboratory analytical reports are attached.
Quality Assurance
S&ME collected additional samples for quality assurance / quality control (QA/QC) purposes in support of the
PFAS data results. Additional sample volume was collected during the sampling of Outfall K, which was submitted
for laboratory analysis by Draft EPA Method 1633 via isotope dilution under the sample identification "DUP". The
analytical results reported by the laboratory for sample "DUP" were consistent with the analytical results for
sample "K" from the Outfall K location.
S&ME collected an equipment rinsate blank sample through the high -density polyethylene (HDPE) and silicone
tubing used in conjunction with the peristaltic pump used to collect the PFAS samples under the sample
identification "EB". PFAS were not detected above the LOQs in this QA/QC sample.

Samples were initially screened by direct inject analysis to determine extraction volume.
For aqueous samples with an observable amount of PM in the sample container a total
suspended solids (TSS) test is performed to determine PM content is >_ 50mg. After
homogenizing and allowing to settle, unless otherwise indicated by a screening analysis or
observed matrix, the sample is measured gravimetrically and spiked with extraction standards
(ES). Sample pH is verified to be 6.5 ± 0.5, adjusted with 5% formic acid or 3% NH4OH as
needed. Each sample is extracted via SPE, transferred to a clean collection tube, spiked with
internal standard (IS), and vortex prior to analysis.
Client approved subsampling due to sample turbidity where necessary to facilitate extraction.
4. Calibration
In the initial calibration, the reported analytes exhibited R12 of >_ 0.99. The reported analytes in
the calibration standards, continuing calibration (concal) and Initial Calibration Verification (ICV)
met the accuracy criterion for native analytes.
5. QC Notes
The QC sample analyses passed all method criteria.
MB2-15570-PFAS was prepped to accompany samples prepped with a lower sample volume
(subsampling) using a different manifold system than samples prepped with MB1 -1 5570-PFAS.
The ion ratios for all compounds were within tolerance.
The samples were extracted within the 28-day from collection holding time and analyzed within
the 28-day from extraction to analysis holding time required by the method.
6. Reporting Notes I
These analyses met the requirements of the DoD QSM 5.4. Any deviations from the
requirements of the reference method or the QSM have been stated above.

ENTHALPY
ANALYTICAL
The following are general reporting notes that are applicable to all Enthalpy Analytical, LLC -
Wilmington, NC data reports, unless specifically noted otherwise.
General Data Qualifiers
• B — The analyte was found in the method blank, at a concentration that was at least 10% of the
amount in the sample.
• Cxx — Two or more congeners co -elute. In EDDs, C denotes the lowest IUPAC congener in a co -
elution group and additional co-eluters for the group (`xx') are shown with the number of the
lowest IUPAC co-eluter.
• E — The reported concentration exceeds the calibration range (upper point of the calibration
curve). For HRMS data, this condition does not imply additional measurement uncertainty. For
LC-MS/MS data, these values should be considered as having measurement uncertainty higher
than values within the calibration range.
• EDL — Estimated Detection Level: The EDL is unique to isotope dilution methods and reflects
the conditions of analysis at the time of analysis, including the equipment used. Where the MDL
is a static value, the EDL is a dynamic value.
• EMPC — Estimated Maximum Possible Concentration: EMPC is specific to Dioxin/Furan tests to
indicate the determined ion -abundance ratio was outside the allowed theoretical range (usually
due to being near the detection limit, although it can very rarely be caused by a co -eluting
interference). The EMPC concentration is adjusted to reflect the value at the theoretical ion -
abundance ratio.
• IR — The ion ratio between the primary and secondary ions was observed to be outside the
method criteria. The analyte concentration may be inaccurate due to interference.
• J — The analyte has a concentration below the minimum calibration level (LOQ value) but greater
than the LOD. These values should be considered as having measurement uncertainty higher than
values within the calibration range
• L - Indicates that an analyte has a concentration below the Minimum Detection Limit (MDL).
The reported concentration is not recommended for regulatory use as the analyte signal may have
a signal-to-noise ratio less than the criteria deemed necessary to be considered a detected analyte.
• LOD — Limit of Detection: For reports conforming to the DOD ELAP QSM, this is the QSM-
defined LOD. For reports conforming to TNI requirements (but not DOD ELAP QSM
requirements), this value is the minimum detection limit (MDL). The LOD is adjusted for sample
weight or volume.
• LOQ — Limit of Quantitation: For reports conforming to the DOD ELAP QSM, this is the QSM-
defined LOQ. For reports conforming to TNI requirements (but not DOD ELAP QSM
requirements), this value is the reporting limit (RL). The LOQ is adjusted for sample weight or
volume.

• <LODQ — Analyte was not found at a concentration high enough to be reported as detected. It is
reported as less than the LOD, and the LOD is given in the parentheses.
• <LOQQ — Analyte was not found at a concentration high enough to be reported as above the
QSM-defined LOQ or TNI defined Reporting Limit. It is reported as less than the LOQ, and the
LOQ is given in the parentheses.
• ND — Indicates a non -detect.
• NR — Indicates a value that is not reportable due to issues observed in sample preparation or
analysis.
• PR — The associated congener(s) is(are) poorly resolved.
• QI — Indicates the presence of a quantitative interference.
• RL — Reporting Limit. Lowest reportable value. The level is higher than the MDL.
• SI — Denotes "Single Ion Mode" and is utilized for PCBs where the secondary ion trace has a
significantly elevated noise level due to background PFK. Responses for such peaks are
calculated using an EMPC approach based solely on the primary ion area(s) and may be
considered estimates.
• U — The analyte was not detected.
• V / Q — The labeled standard recovery is not within method control limits.
• X — Indicates the result is from re-injection/repeat/second-column analysis.
Lab Identifiers/ Data Attributes
• AR — Indicates use of the archived portion of the sample extract.
• CU — Indicates a sample that required additional clean-up prior to HRMS injection/processing.
• D — Dilution Data. Result was obtained from the analysis of a dilution. The number that follows
