Subject: Surface Water Sampling and Analytical Report (2nd Quarter)
NCDEQ UST Section Incident No. 14908
Charlotte Douglas International Airport
Former U.S. Airways Maintenance Hangar
5020 Hangar Road
Charlotte, North Carolina
Dear Mr. Bell:
Charlotte Douglas International Airport (CDIA) 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 May 2021 Mr. Wes Bell of the North Carolina Department of Environmental Quality (NCDEQ),
Division of Water Resources (DWR) requested quarterly surface water sampling and analysis at
Coffey Creek to assess whether dissolved petroleum hydrocarbon constituents are present in
the stream.
Surface Water Sampling and Analysis
On June 5, 2023, CDIA personnel collected one surface water sample (SW002) 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 SWO02 was collected approximately 20 feet downstream of

(Lug .7ro,
CHARLOTTE DOUOLAS'
INTERNATIONAL AIRPORT
the fuel seepage location. The sample 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 Pace Analytical Services, LLC in
Huntersville, North Carolina for analysis. The sample was maintained under chain -of -custody
protocol. The laboratory analyzed the surface water sample for volatile organic compounds
(VC)Cs) 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
SW002. The laboratory report is attached. The next surface water sampling event is planned for
September 2023.
Closing
Should you have any questions concerning this submittal or require additional information,
please contact me at [phone] [e-mail].
Sincerely,

QUALIFIERS
Project: WATER SAMPLING
Pace Project No.: 92670516
DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
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.
TN -The NELAC Institute.
ANALYTE QUALIFIERS
IH This analyte exceeded secondary source verification criteria high for the initial calibration. The reported results should be
considered an estimated value.
L1 Analyte recovery in the laboratory control sample (LCS) was above QC limits. Results for this analyte in associated
samples may be biased high.
MO Matrix spike recovery and/or matrix spike duplicate recovery was outside laboratory control limits.
M1 Matrix spike recovery exceeded QC limits. Batch accepted based on laboratory control sample (LCS) recovery.
R1 RPD value was outside control limits.
SO Surrogate recovery outside laboratory control limits
