Subject:Plan Approval, Well Equipping & Arsenic Blending Plan, Kanosh Town Well #1 (WS005); Kanosh Town, System #14006, File #13315
Dear Lorin Dean Shumway:The Division of Drinking Water (the Division) received the plans and specifications for equipping the Kanosh Town Well #1 from your consultant, Benjamin Coray
with Sunrise Engineering, on May 16, 2025. Written review comments were sent to your consultant on June 3, 2025, and revised plans and specifications were received on July 2, 2025. The
Division issued Plan Approval for drilling Kanosh Town Well #1 on March 27, 2023.
Our understanding of the project is that Kanosh Town drilled a new well adjacent to the existing storage tanks, east of town and alongside the Kanosh Canyon Road. The well was drilled
to a depth of 670 feet and has a 12-inch diameter steel production casing. The well has two screened intervals, one from 420 ft. to 520 ft. and the second from 540 ft. to 658 ft. The
well also has a surface seal of cement/sand grout extending down to 106 ft. A 30 horsepower submersible pump capable of producing 300 gallons per minute (gpm) at 270 ft. of total dynamic
head will be installed in the well as the permanent production pump. The well was test pumped for over 24 hours at 970 gpm and had a drawdown of 15 feet. A new wellhouse will be constructed
as part of this project that will include the well discharge piping and appurtenances as well as the spring transmission pipeline. The new source chemistries for the Kanosh Town Well
#1 showed that the Arsenic concentration is 12.8 parts per billion, Total Dissolved Solids are 1,410 parts per million and Chloride is 608 parts per million. These values exceed the
allowable Maximum Contaminant Level (MCL) for each contaminant. The water from the well will be mixed with the combined flow from Springs #1 - #4.
Currently, the new Well #1 will only be needed during the summer months during peak demand times. Kanosh Town does not anticipate having to use the well during the winter months.
The blended water from the existing springs and new Well #1 will produce the following blended concentrations based on the proposed 1:1 mixing ratio and the contaminant concentrations
for each flow.

The current MCL for arsenic is .010 mg/L and the SMCL for TDS is 1,000 mg/L. The proposed blend for these contaminants are below the drinking water as shown in the table above.
We have received the following information for Kanosh Town Well #1:
Certification of well seal.
Well driller’s report (well log).
Aquifer drawdown test results (step drawdown test and constant-rate test).
New Source Chemical Analysis of the well water.
Plans and specifications for equipping the well.
30 HP Submersible Pump producing 300 gpm
Well head discharge piping.
Well house design
Equipment and controls to blend well water with the spring water
We have completed our review of the plans and specifications, stamped and signed by Benjamin Q. Coray, P. E., and dated July 2, 2025,and find they basically comply with the applicable
portions of Utah’s Administrative Rules for Public Drinking Water Systems in R309. On this basis, the plans for equipping Kanosh Town Well #1 are hereby approved and the Division concurs
with the proposed Arsenic Blending Plan.
This approval pertains to construction only. An Operating Permit must be obtained from the Director before the Kanosh Town Well #1 may be put into service. A checklist outlining the
well approval process, including the items required for issuing an operating permit for this well is enclosed for your information. Approvals or permits from the local authority or county

may be necessary before beginning construction of this project. As the project proceeds, notice of any changes in the approved design, as well as any change affecting the quantity or
quality of the delivered water, must be submitted to the Division. We may also conduct interim and final inspections of this project. Please notify us when actual construction begins
so that these inspections can be scheduled.
This approval must be renewed if construction has not begun or if substantial equipment has not been ordered within one year of the date of this letter.
Future Source Chemical Monitoring Requirements
Upon the issuance of an operating permit, compliance with all of the chemical MCLs including arsenic and TDS will be evaluated through sampling conducted at a new sampling point located
at or near the outflow of the 250 K Tank (ST002) and 200 K Tank (ST003). This new sampling point is identified as Arsenic Blending (TP002). This sampling location shall be located after
blending has occurred and be before or at the first service connection.
The specific monitoring requirements associated with the blending plan will be presented in the operating permit for Well #1 (WS005). Please contact David Kruse at [e-mail] or
385-566-7789 with any questions regarding this system's source chemical monitoring and reporting requirements.
If you have any questions regarding this approval, please contact John Chartier, P.E., DEQ Central District Engineer, at [phone], or me at [phone].
Sincerely,
Michael Newberry, P.E.
