RE: Well Seal Certification for Hole in the Rock Backup Well (WS008)
Oquirrh Mountain Water Company
Public Water System No. UTAH23076, File No. 12942
Tooele County, Utah

Dear Mr. Fryer,
On March 26, 2022, I witnessed the sealing procedure for the well referenced above as
authorized by R309-515-6(5)(b). This letter is to certify that the well sealing procedure
met the requirements of Utah Administrative Code (UAC), Rule R309-515-6(6)(i), Well
Sealing Techniques and Requirements, and Rule R655-4-11.4, Surface Seals and
Interval Seals.
The following tables and figures summarize information about the well, the Public Water
System (PWS), the well driller and the well sealing process.

This well seal certification is not a Plan Approval to construct a public drinking
water well or an Operating Permit to use the well as a public drinking water source.
Such approval may only be granted by the Director of the Division of Drinking Water. A
copy of this letter has been sent to the Director of the Division of Drinking Water.

WELL CONSTRUCTION INFORMATION
Hole in the Rock Backup Well - Grout Seal Certification
Description of
Well Sealing
Process:
On March 26 and 27, 2022, Lang Equipment (Lang) sealed the 16-inch diameter
production casing for the Hole in the Rock Backup Well from a depth of 143 feet up to
ground surface with neat cement grout. Each neat cement grout batch was prepared in
a 500-gallon mixer and grout pump and installed in the borehole through a 2.3-inch
diameter (BQ) tremie pipe. Each neat cement grout batch was prepared by mixing a
supersack (approx. 2200 pounds) of Quikrete Type I/II Portland cement with
approximately 130 gallons (gals) of water. A total of 9 batches (264 cubic feet) were
mixed and installed in the borehole and each batch was installed immediately after
mixing and measuring the grout density.
Grout Material:Neat cement grout
Grout Volume:The theoretical volume of the annular space between the 16-inch diameter production
casing and the borehole wall from ground surface to a depth of 143 feet is 190 cubic
feet. Lang installed approximately 264 cubic feet of neat cement grout around the
production casing. The discrepancy between the theoretical volume and the installed
volume is due to washouts in the borehole and grout flowing out into the formation.
Grout Density:The grout density was measured to be between 15.0 and 15.6 pounds per gallon
(lbs/gal) prior to installation in the borehole. The average density was 15.2 lbs/gal.
Method of
Placement:
Tremie pipe and grout pump.
Depth from
Surface:
The certified cement grout well seal extends from ground surface to a depth of 143 feet.
Did Grout Come
to the Surface?
Yes grout came to the surface.
Length of
Tremie Pipe:
The bottom of the tremie pipe was set to a depth of approximately 140 feet. The tremie
pipe was removed in stages after mixing and installing 2 batches of neat cement grout.
Issues Observed
During Well
Sealing:
No issues were observed during well sealing
