5020 Hangar Road

WSP Project: 6228-21-0061
Dear Mr. McDorman:
WSP USA Environment & Infrastructure Inc. (WSP) is pleased to submit this Surface Water Sampling and Analysis Report
for the above -referenced property in Charlotte, North Carolina. Included in this report is an outline of our
understanding of the project background, description of the sampling activities and results.
Project Background
U.S. Airways, Inc. (U.S. Airways) previously operated an aircraft jet fuel defueling/refueling system at the former
U.S. Airways Maintenance Hangar located at 5020 Hangar Road in Charlotte, North Carolina. The site is located in
the southwest portion of the Charlotte/Douglas International Airport property (Tax Parcel ID 115-211-05).
American Airlines (formerly U.S. Airways) currently leases the maintenance hangar facility from the City of
Charlotte and performs aircraft maintenance at the property. A 1995 release of petroleum occurred at the hangar
location. In December 2018, CLT personnel observed evidence of petroleum seepage from the bank of Coffey
Creek approximately 800 feet north of contaminant source area (Figure 1).
In email correspondence, dated May 13, 2021, Mr. James McDorman informed WSP personnel that Mr. Wes Bell
of the North Carolina Department of Environmental Quality (NCDEQ), Division of Water Resources (DWR)
requested performance of quarterly surface water sampling and analysis of Coffey Creek to assess whether
dissolved petroleum hydrocarbons are present in the stream.
Surface Water Sampling and Analysis
On September 27, 2023, WSP personnel collected one surface water sample (SW-01) from Coffey Creek. The
sample was collected using a stainless -steel cup attached to a stainless -steel rod. This device allows for the water

sample to be dipped from near the center of the stream by the sampler. The sampling cup was decontaminated
prior to use by rinsing with isopropyl alcohol, followed by distilled water.
Sample SW-01 was collected approximately 20 feet downstream of the last petroleum absorbent boom. The
location is shown on Figure 1. The collected sample was poured into laboratory -provided containers with
appropriate preservatives. The sample containers were placed in an ice -filled sample cooler and delivered to
Waypoint Analytical, LLC (Waypoint) in Charlotte, North Carolina for analysis. The sample was maintained under
chain -of -custody protocol. The laboratory analyzed the surface water sample for volatile organic compounds
(VOCs) by EPA Method 6200B including MTBE and semi -volatile organic compounds (SVOCs) by EPA Method
625.1.
Results
The results of the analyses of sample SW-01 identified detectable concentrations of chrysene,
dibenz(a,h)anthracene, and indeno(1,2,3-cd)pyrene. Chrysene is not typically associated with jet fuel, but is
produced as a byproduct of incomplete combustion of coal and gasoline, and was identified in the surface water
sample at a concentration of 2.07 µg/L. This concentration of chrysene exceeded the NCAC 2B Standard for Total
Polynuclear Aromatic Hydrocarbons (PAHs) of 0.0311 µg/L (Class C: Fish Consumption). Indeno(1,2,3-cd)pyrene
and dibenz(a,h)anthracene are not typically found in jet fuel but are common oxygenated compounds in gasoline
and diesel exhaust. Indeno(1,2,3-cd)pyrene was identified in the surface water sample at concentration of 2.12
µg/L, which exceeded the NCAC 2B Standard for Total PAHs of 0.0311 µg/L (Class C: Fish Consumption).
Dibenz(a,h)anthracene was identified in the surface water sample at concentration of 2.28 µg/L, and did not
exceed the NCAC 2B Standard for In Stream Target Values related to Aquatic Life and Secondary Recreation of 5
µg/L (Class C). It is WSP's opinion that the presence of chrysene, dibenz(a,h)anthracene, and indeno(1,2,3-
cd)pyrene is likely not related to the contaminants (i.e. jet fuel) known to be present upgradient of Coffey Creek.
Certain constituents were identified at concentrations that are considered "estimated" (noted with a "J" on Table
1) because they were identified at a level above the Method Detection Limit (MDL), but below the Reporting Limit
(RL). These included benzo(a)anthracene, benzo(a)pyrene, benzo(g,h,i)perylene, and benzo(k)fluoranthene, which
are also not typically found in jet fuel. The laboratory report is attached. The next surface water sampling event is
planned for December 2023.
