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) June
7, 2022, approved Environmental Management Plan (EMP). Included in this report is a description of the
field activities, and the results obtained.
On November 28, 2022, ECS mobilized to the subject site to collect one (1) water sample, identified as
WS-4. The water sample was 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 the
sampling event in order to provide for a representative water quality sample from the FRAC tank. The
FRAC tank, was observed to be near 100% capacity at the time of sampling on November 28, 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-4, was submitted to Eurofins, a North Carolina
certified laboratory located in Savannah, Georgia (NC Certification No. 269) for analysis of 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.
Laboratory analysis of WS-4 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.

Water Sampling Letter Report
Wrights Executive Sales 11
Brownfield Project No. 24007-20-032
ECS Project No. 49-10039-B
Based on this summary report's findings, ECS concluded that the laboratory analytical results of the
water sample collected on November 28, 2022, and identified as WS-4, 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

Receipt
The sample was received on 11/29/2022 7:00 AM. Unless otherwise noted below, the sample arrived in good condition, and, where
required, properly preserved and on ice. The temperature of the cooler at receipt time was 1.4°C
GC/MS VOA
Method 8260D: The laboratory control sample (LCS) for analytical batch 680-753755 recovered outside control limits for the following
analytes: 1,2,3-Trichlorobenzene, 1,2,4-Trichlorobenzene, 1,2-Dibromo-3-Chloropropane, Naphthalene and Vinyl chloride. These analytes
were biased high in the LCS and were not detected in the associated samples; therefore, the data have been reported.
Method 8260D: The laboratory control sample duplicate (LCSD) for analytical batch 680-753755 recovered outside control limits for the
following analytes: 1,2,3-Trichlorobenzene, 1,2,4-Trichlorobenzene, 1,2-Dibromo-3-Chloropropane, Dichlorodifluoromethane,
Naphthalene and Vinyl chloride. These analytes were biased high in the LCSD and were not detected in the associated samples;
therefore, the data have been reported.
Method 8260D: The method blank for analytical batch 680-753755 contained 1,2,3-Trichlorobenzene and 1,2,4-Trichlorobenzene above
the method detection limit (MDL). None of the samples associated with this method blank contained these target compounds; therefore,
re -extraction and/or re -analysis of samples were not performed.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
GC/MS Semi VOA
Method 8270E: The following samples listed formed emulsions during the extraction procedure: WS-4 (680-226360-1). The emulsions
were broken up using Sodium Sulfate.
Method 8270E: The laboratory control sample (LCS) and / or laboratory control sample duplicate (LCSD) for preparation batch
680-753436 and analytical batch 680-753876 recovered outside control limits for the following analytes: 3,3'-Dichlorobenzidine. These
analytes were biased high in the LCS and were not detected in the associated samples; therefore, the data have been reported.
No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.
