Dear Mr. McDorman: 
WSP USA Environment & Infrastructure Inc. (WSP) formerly known as Wood Environment & Infrastructure Solutions, Inc. 
(Wood) 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 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 December 14, 2022, WSP personnel collected one surface water sample (4Q‐SW‐1) 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 4Q‐SW‐1 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 did not identify any detectable constituents in surface water sample 4Q‐SW‐1. The 
laboratory report is attached. The next surface water sampling event is planned for March 2023.  
Closing 
We appreciate your selection of WSP for this project and look forward to assisting you further on this project. If 
you have questions, please contact us. 
Sincerely, 
WSP USA Environment & Infrastructure Inc.

Dear Rob Foster:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 12/14/2022 for the analyses presented in the following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in
accordance with the applicable analytical method.
The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all
parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of
sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as-
received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to the samples included in this report. Please do not hesitate to contact me or client services if you have any questions or need additional information.
Sincerely,
Danyale Love Project Manager
