WI0500181_Inspection Letter_2100 Dimmocks Mill Rd-FINAL

Subject: Geothermal Well Renewal
Permit # WI0500181
Summary of Inspection and Sampling on March 14, 2024

Mr. Dyson:

In support of your request for renewal of the above-referenced geothermal well permit, Tyler Clark from
the Division of Water Resources Performed an inspection and collected samples from the well influent
and effluent on March 14, 2024. The permittee, William Dyson, was present during the inspection, and
identified the location of the well. The well is used for geothermal heat exchange and water supply.
During the inspection, the geothermal system was in operation.

The well and exposed well piping was covered with a fiberglass rock and was in good condition, with no
leaks observed. The wellhead appeared to be secure. No well identification plate was observed. The
influent and effluent piping was not labeled, but the inspector labeled them in the field prior to taking
photographs (Attachment 1). Influent (W1-I) and effluent (W1-E) water samples were collected from the
sample ports at the well head. Both sample ports were disinfected with a 70% isopropyl solution prior to
sampling. Samples were collected directly from the sample ports following disinfection. Groundwater
quality (temperature, pH, dissolved oxygen, conductivity, and salinity) was measured in the field. The
measurements are relatively similar between the well effluent and the system discharge.

Samples were delivered to the Division of Water Resources Laboratory on March 14, 2024. Laboratory
analytical results were returned on February 13, 2024 (Attachment 3). Concentrations of the constituents
analyzed were below the North Carolina Groundwater Standards (NCAC 15A.02L). The concentration of
the constituents analyzed were relatively similar between the influent and effluent samples. The
concentration values for arsenic were slightly over half the North Carolina Groundwater Standards
(NCAC 15A.02L). The 2L limit is 10 mg/L and your well showed 5.6 and 6 mg/L for both the effluent
and influent samples. Arsenic is a naturally occurring element and is well-known to occur in elevated
levels in Orange County.

Neither the field measurements nor the laboratory results suggest a concern regarding groundwater
quality. Based on the inspection of the well head, and the laboratory analytical results for the samples
collected, the continued use of the well for geothermal heat exchange and consumption is appropriate.
