Re: Ground Water Monitoring Report
Han-Dee Hugo 61
11924 US 70 Business Highway West
Clayton, Johnston County
Incident # 48152
Site Ranking: Pending
GRI # 5812

Dear Ms. Brown:

Geological Resources, Inc. (GRI) presents the results of the ground water sampling event at the Han-Dee
Hugo 61 site in Clayton, North Carolina. The activities were conducted in response to correspondence
from the NCDEQ dated October 20, 2022.

On December 5, 2022, monitoring well MW-1 was gauged, purged, and sampled per NCDEQ guidelines.
Depth to ground water from the top of well casing was 13.66 feet below ground surface. Ground water
samples were submitted for analyses of VOCs by EPA Method 602. A Site Location Map and Site Map
have been included as Figures 1 and 2, respectively.

Please see the attached laboratory report for the results of the December 2022 ground water sampling.
Concentrations of benzene, toluene, ethylbenzene, total xylenes, and naphthalene that exceeded the
Maximum Allowable Concentrations (MACs) as specified in T15A NCAC 2L.0202 were reported in the
ground water samples collected from MW-1. No contaminant concentrations exceeded the Gross
Contaminant Levels (GCLs).

Temporary monitoring well TMW-4 was installed as part of a site assessment for property refinancing;
TMW-4 was abandoned at the conclusion of the site assessment activities. Monitoring well MW-1 was
installed in the same location during the Limited Site Assessment. To date, three ground water samples
(September 16, 2021, April 19, 2022, and December 5, 2022) have been collected from this location and
no GCL violations have been reported.

According to the receptor survey that was conducted in April 2022, no active water supply wells are
located within 1,000 feet of the site. Public water is available to the subject site and to all surrounding
properties. No surface water bodies were identified within 500 feet of the site.

Based on the lack of receptors and ground water quality, the site risk should be classified as low and
subsequent to filing a Notice of Residual Petroleum for ground water and completing public notification,
the incident should be closed with no further action.

Please contact me at 704-698-1254 or [e-mail] with any questions or comments.

Sincerely,
Rae Troiano Brown, P.G.
Project Manager

Dear Rae Brown:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 12/6/2022 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.
