Dear Mr. Vinay:
Freese & Nichols, Inc. provided S&ME, Inc. (S&ME) with a copy of the letter dated February 27, 2017, from
North Carolina Department of Environmental Quality (NCDEQ) to the City of Morganton – Department of
Water Resources. Page 2 of this letter indicated that a site visit conducted by the NCDEQ revealed that
temporary well TW-1 was never abandoned, and required proper abandonment. With receipt of this
information S&ME’s certified well driller, Gary Simcox visited the subject site on March 30, 2017, to
observe the reported condition. Based on our site observations, the temporary well in question was soil
boring SB-1 (TW-1 original), completed on July 15, 2014, which was terminated upon encountering probe
refusal at 15 feet below the land surface. At that time, a 2-inch PVC standpipe was installed in the boring
to monitor for the potential presence of groundwater, which was never detected. Temporary wells TW-1,
TW-2, and TW-3 were installed during the July 2014 assessment activities and they were properly
abandoned following the collection of groundwater samples for the assessment. Although not a formal
temporary well, S&ME did not abandon this soil boring during 2014. On March 30, 2017, soil boring SB-1
(TW-1 original) was abandoned by removal of the upper section of PVC standpipe and filling the borehole
with bentonite. A copy of the boring log for SB-1 is attached for reference.
Please contact the undersigned if there are any additional questions regarding this matter.
Sincerely,
S&ME, Inc.
