Subject: Letter Report of Groundwater Sampling of Geothermal Wells
Catawba College
2300 West Innes Street
Salisbury, Rowan County, North Carolina
Permit No. W10300045
Progress Project No. 1020105.001
Dear Mr. Watson:
On behalf of our client, Catawba College, Progress Environmental Group, Inc. (Progress) respectfully
submits this Letter Report of Groundwater Sampling of Geothermal Wells on the campus of Catawba
College located at 2300 West Innes Street in Salisbury, North Carolina.
On July 23, 2020, Mr. Bradley Snover of Stewarts Environmental Services was on -site to collect samples
from six of the geothermal wells for laboratory testing. Specifically, Wells 10, 13, 4, 9, 3, and 16 were
sampled. The purpose of the sample collection was the renewal of the permit to utilize the closed loop
system as part of the heating and cooling system at the college. A copy of the current permit is included in
the Appendix.
The groundwater samples were collected directly from spigots located at or the near the respective
wellheads. The spigots were opened and water was allowed to flow for more than 15 minutes prior to
sample collection. Field measurements were collected and recorded from each wellhead using a YSI 556
multi -meter. Field sampling sheets are included in the Appendix.
The groundwater samples were collected and decanted in laboratory supplied bottles. The bottles were
immediately placed in a cooler packed with ice to maintain sample integrity. The coolers were delivered
under chain -of -custody to Statesville Analytical in Statesville, North Carolina.
The groundwater samples were analyzed for aluminum, barium, cadmium, calcium, chromium, copper,
iron, magnesium, manganese, nickel, potassium, silver, and zinc using EPA Method 200.7, arsenic and
selenium using EPA Method 200.8, sodium using Standard Method 3111.8, chloride using Standard
Method 4500CIC-2011, fluoride using Standard Method 4500FC-2011, lead using Standard Method
3113B-2004, nitrate and nitrite using Method 353.2, sulfate using Standard Method 4500 SO4-E, hardness

by calculation, total coliforms using Standard Method 9222B, total dissolved solids using Standard Method
2540 C 18' edition, and fecal coliforms using Method IDEXX Colilert 18 MPN.
A copy of the laboratory test report and chain -of -custody is included in the Appendix. The results of the
laboratory testing were compared to the North Carolina 2L Groundwater Quality Standards, if applicable.
Total coliforms were detected in the groundwater samples collected from Well 13 (27 MPN), Well 4 (2.0
MPN), Well 9 (17 MPN), and Well 3 (6.3 MPN). Fecal coliforms were not detected in any of the
groundwater samples.
We appreciate your selection of Progress for this project. If you have any questions, please do not hesitate
to contact us.
Sincerely,

2. If a well will no longer be used for any purpose, then it should be permanently abandoned according to
rule 15A NCAC 02C .0113(b) in order to prevent the well from deteriorating and acting as a source or
conduit of contamination, which is prohibited by General Statute 87-88(c).

the Permittee shall permanently abandon that injection well in accordance with the procedures specified in
15A NCAC 02C .0113(b), which include, but are not limited to, the following:
(A) All casing and materials may be removed prior to initiation of abandonment procedures if
such removal will not be responsible for, or contribute to, the contamination of an
underground source of drinking water.
(B) The entire depth of each well shall be sounded before it is sealed to insure freedom from
obstructions that may interfere with sealing operations.
(C) Each well shall be thoroughly disinfected prior to sealing in accordance with rule 15A
NCAC 02C .0111(b)(1)(A),(B), and (C).
(D) Each well shall be completely filled with cement grout, which shall be introduced into the

required in Item #2 below.
2. Any injection well shall be constructed in accordance with the requirements of rule 15A
NCAC 02C .0107 except that the entire length of the casing shall be grouted in such a way
that there is no interconnection of aquifers or zones having differences in water quality that
