NX Is I ) July 5, 2024 Mr. Jimmy D. Jordan, LG Environmental Manager Charlotte Douglas International Airport 5601 Wilkinson Boulevard Charlotte, North Carolina 28208 Subject: Surface Water Sampling and Analysis Report (Second Quarter) Former U.S. Airways Maintenance Hangar NCDEQ UST Section Incident No. 14908 5020 Hangar Road Charlotte, North Carolina WSP Project: 6228-24-0007 Dear Mr. Jordan: 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 June 3, 2024, WSP personnel collected one surface water sample (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. WSP USA Environment & Infrastructure Solutions Inc. 1001 Morehead Square Drive, Suite 610 Charlotte, North Carolina 28203 NC Geology License: C-247 T: 704-417-5152 Surface Water Sampling and Analysis Report Former U.S. Airways Maintenance Hangar WSP Project: 6228-24-0007 July 5, 2024 Sample 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 analysis of sample SW-1 identified no detectable concentrations of contaminants of concern. A table summarizing the current and historical results and the laboratory report are attached. The next surface water sampling event is planned for September 2024. 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.

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. TNI - The NELAC Institute. ANALYTE QUALIFIERS E Analyte concentration exceeded the calibration range. The reported result is estimated. M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
