Dear Ms. Samaha-Smith:
ECS Southeast, LLP (ECS) is pleased to present the results of water sampling conducted in support of
ongoing Brownfield redevelopment activity at the above -referenced site (Figures 1 and 2). ECS's water
sampling services were provided in accordance with the North Carolina Department of Environmental
Quality (NCDEQ) Division of Waste Management (DWM) Brownfields Program (the Program) April 19,
2021 approved Environmental Management Plan (EMP). Included in this report is a description of the field
activities, and the results obtained.
On March 25, 2022, ECS mobilized to the subject site to collect one (1) water sample, identified as WS-1.
On July 20, 2022, ECS remobilized to the subject site to collect one (1) water sample, identified as WT-2.
The water samples were collected from an onsite 8,400-gallon FRAC tank utilizing new powder free
nitrile gloves and a new dedicated disposable polyethylene bailer. The location of the FRAC tank is
illustrated on Figure 3. Water in the FRAC tank was circulated with pumps and hosing just prior to and
during both sampling events in order to provide for a representative water quality sample from the
FRAC tank. The FRAC tank, was observed to be near 75% capacity at the time of sampling on March 25,
2022 and near 100% capacity at the time of sampling on July 20, 2022. The water contained in the FRAC
tank was generated from precipitation which had accumulated in various open excavations on the
Brownfields site and was not reinfiltrating at a rate which supported ongoing redevelopment activities in
those areas.
Following collection, the water sample, identified as WS-1, was submitted to Pace Analytical Services,
LLC (Pace), a North Carolina certified laboratory, located in Huntersville, North Carolina (NC Certification
No. 12), and the water sample, identified as WT-2, was submitted to Eurofins, a North Carolina certified
laboratory located in Savannah, Georgia (NC Certification No. 269) for analysis for volatile organic
compounds (VOCs) using EPA Method 8260 and semi -volatile organic compounds (SVOCs) using EPA
Method 8270. ECS maintained chain of custody (COC) procedures throughout the sample collection and
transportation process.

Water Sampling Letter Report
Wrights Executive Sales 11
Brownfield Project No. 24007-20-032
ECS Project No. 49-10039-B
Laboratory analysis of WS-1 and WT-2 did not report targeted VOCs or SVOCs at concentrations above
their respective laboratory method detection limits (MDLs). The laboratory analytical reports and a copy
of the COC documentation are included as attachments.
Based on this summary report's findings, ECS concluded that the laboratory analytical results of the
water sample collected on March 25, 2022 and identified as WS-1, and the water sample, identified as
WT-2 and collected July 20, 2022, did not report targeted compounds above their respective North
Carolina Administrative Code (NCAC) 2B Surface Water Standards. Therefore, based upon these results
and in accordance with the Brownfields approved EMP, ECS recommended this water be managed on
the site or discharged to the storm sewer in accordance with municipal, state, and federal requirements.
ECS appreciates the opportunity to work with the Brownfields Program. If you have any questions
concerning this report or this project, please contact us.
Sincerely,
ECS SOUTHEAST, LLP

QUALIFIERS
Project: Foster Street + Greer Street
Pace Project No.: 92595586
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.
IK The recalculated concentration of the calibration standard(s) did not meet method acceptance criteria; this result should
be considered an estimated value.
IL This analyte exceeded secondary source verification criteria low 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.
v1 The continuing calibration verification was above the method acceptance limit. Any detection for the analyte in the
associated samples may have a high bias.
v3 The continuing calibration verification was below the method acceptance limit. Any detection for the analyte in the
associated samples may have low bias.
