WR Project Number: 23-0307-EU Ms. Ghiold:
WithersRavenel, Inc. (WR) has prepared this Letter Report documenting the completion of an
Aggressive Fluid Vapor Recovery (AFVR) event at the US 221 Construction site in Marion, McDowell County, North Carolina. Activities outlined herein were completed under NCDEQ Contract # N70522-C, Task Authorization (TA) 01 for the site, issued by NCDEQ on June 21, 2023. Aggressive Fluid Vapor Recovery Event – MW-1
On July 19, 2023, WR personnel, along with Evo Corporation (EVO) mobilized to the site and conducted an eight-hour AFVR event. This event focused on total fluid recovery from Type II monitoring well MW-1. Prior to performing the AFVR event, WR personnel gauged the depth-to-
water within MW-1. Light, non-aqueous phase liquid (LNAPL) was not measured within MW-1.
Depth to water and depth to bottom of the well are included in the table below.
Well ID DTP DTW PT DTB
MW-1 --- 28.30 --- 35
All Measurements shown in feet
DTP = Depth to Product/LNAPL DTW = Depth to Water
PT = Product/LNAPL Thickness DTB = Depth to Well Bottom
The AFVR event included application of vacuum for 8-hours on monitoring well MW-1. Vacuum on the well remained at 24-inches (in) of mercury throughout the event. Air stream concentrations from the discharge of the blower were measured using a field calibrated RAE Systems MiniRAE

3000 Photo Ionization Detector (PID). Measured concentrations ranged from 95 parts per million (ppm) to 1,119 ppm. Stack temperature, velocity and relative humidity values were measured with a TSI, Inc. straight probe Model 964 thermoanemometer. At the conclusion of the AFVR, a total of 195 gallons (gal) of liquids were recovered.

Emissions through volatilization of organic compounds (based on mass flow calculations) were calculated to be approximately 2.21 pounds, equating to 0.35-gal of petroleum removed as vapor. The disposal manifest and AFVR calculations are included in Appendix A while field notes and site photographs are provided in Appendix B.

Groundwater Sampling WR personnel mobilized to the site on August 24, 2023, for the purposes of collecting groundwater samples from monitoring wells MW-1 and MW-7R as well as water supply wells
WSW-C, WSW-F, WSW-I, and WSW-U.
Prior to purging and sampling, the wells were gauged with an electronic water level indicator. Groundwater was measured within the well at a depth of 28.60 ft beneath the well’s top of casing (ft btoc) in MW-1 to 27.10 ft btoc in MW-7R. After gauging, MW-1 and MW-7R were purged
using a dedicated polyethylene bailer. The samples from MW-1 and MW-7R were submitted to
Waypoint Analytical, Inc. (Waypoint) for analysis for VOCs by SM6200B. WR also obtained verbal permission from the property owners associated with water supply wells WSW-C, WSW-F, WSW-I, and WSW-U. Each water supply well was allowed to purge for
approximately 10 minutes and the sample was collected from an exterior spigot. WR also collected
a field blank using laboratory supplied deionized water. The collected samples were submitted to Waypoint for analysis for VOCs by SM6200B. Laboratory Results
Monitoring Wells No Light Non-Aqueous Phase Liquid (LNAPL) was measured in MW-1 or MW-7R during the August 2023 sampling event. No petroleum related compounds were detected above the Gross Contaminant Levels (GCLs) in monitoring wells MW-1 or MW-7R. Several petroleum related
compounds were reported in MW-1 and MW-7R at concentrations that exceed the 15A NCAC
2L Groundwater Quality Standards (2L Standards). The following change in Total VOCs concentrations was observed between August 2022 and August 2023.
Well ID Sample Date Total VOCs Sample Date Total VOCs Percent Change
MW-1 8/4/2022 26,739 8/24/2023 26,099 -2.4%
MW-7R 8/4/2022 2,683 8/24/2023 1,366 -49.1 %

The following change in Total VOCs concentrations was observed between the listed historical groundwater event and the August 2023 event.
Well ID Sample Date Total VOCs Sample Date Total VOCs Percent Change
MW-1 5/14/10 30,830 8/4/2022 26,099 -15.3%
MW-7R 4/19/18 1,904 8/4/2022 1,366 -28.3 %
Water Supply Wells No petroleum related compounds were reported above the method detection limits (MDLs) in the laboratory results for the groundwater samples collected from water supply well WSW-C, WSW-
F, WSW-I, and WSW-U. Toluene was reported above the MDL in the field blank but was identified
by the laboratory as a probable laboratory contaminant. Analytical results are provided Table B-4. The laboratory report, a photographic record, and field notes associated with this event are included as attachments.

LABORATORY ANALYTICAL REPORT

Laboratory's liability in any claim relating to analyses performed shall be limited to, at laboratory's option, repeating the
analysis in question at laboratory's expense, or the refund of the charges paid for performance of said analysis.

Dear Matt James:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 8/25/2023 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,
Angela D Overcash Senior Project Manager
