Dear Mr. & Mrs. McWilliams:
On February 17, 2021 staff from the Division of Water Resources inspected your geothermal
underground injection well system. Samples were collected from the water supply well and the
water prior to entering the injection well. The samples were analyzed by the Division's laboratory
for total and fecal coliform bacteria, total dissolved solids, metals, nitrates and other inorganic
constituents. No exceedances of the State Groundwater Standards were observed except for total
coliform bacteria. The holding time was exceeded for the laboratory's quality control limits, so
there may be some uncertainty to the results. It is suggested to chlorinate both wells, attached is a
brochure that provides directions for the disinfection of wells. Copies of the laboratory results are
also enclosed for your review.
Should you have any questions concerning this letter, please feel free to contact me at (910) 796-
7215 or by email at [e-mail].
Sincerely,
