Dear Mr. and Mrs. Clark:

Subject: UIC Sampling Results
Permit No.: WI0300380
8426 Catawba Cove Dr., Belmont
Gaston County
On October 4, 2023, staff from the Mooresville Regional Office (MRO), Water Quality Regional
Operations Section, sampled the influent and effluent lines of your geothermal underground injection well
heat pump system at the subject address. The samples were analyzed by the Division of Water Resources
(DWR) laboratory for metals, nitrates and other organic and inorganic constituents. A complete copy of
the lab results and instructions on how to interpret the lab results are enclosed.
Due to an internal issue, the Coliform Bacteria and Total Coliform bacteria samples were received out -of -
hold time at our laboratory. Therefore, bacteria sample results are not included in this results letter. The
permittee was requested to contact the Gaston County Health Department to have Toal and Fecal
Coliform samples collected for the UIC system. It is the understanding of the MRO that bacteria samples
collected by Gaston County indicated no elevated Coliform bacteria was present in the well.
The remaining constituents were all below the 2L standards and are therefore in compliance with limits
for water quality standards.
Should you have any question regarding the laboratory analysis results, I may be reached by phone at
(704) 663-1699 or email edward.watson@deq.nc.gov.
Sincerely,
