Dear Chad McPherson:The Division of Drinking Water (the Division) received the plans and specifications for equipping Leamington’s Town Well REPL-1 (WS005) from your consultant, James
Saunders with Jones & DeMille Engineering on February 24, 2025. Review comments were sent to your consultant on March 6, 2025, and revised plans and specifications were received on
March 20, 2025. The Division issued Plan Approval for drilling Town Well REPL-1 on August 23, 2022.
Our understanding of the project is that the replacement well will have a new well building to house the well discharge piping and appurtenances and the existing well building will not
be used. The replacement well was drilled to a depth of 890 feet and was test pumped at 630 gallons per minute (gpm) for 24 hours. The wellhead was finished with a pitless adapter unit
and will be located adjacent to, and on the south side of the new well building. The well will be equipped with a 40 horsepower submersible pump and motor. The well pump discharge rate
will be 240 gpm at the calculated total dynamic head of 450 feet. This well is identified as WS005 in the Division’s database.
The Town Well REPL-1 is being reviewed according to the Division’s rules for a replacement well. This replacement well is required to be in full compliance with the replacement well
approval issued by the Utah Division of Water Rights, dated August 1, 2022. This includes abandonment of the old well that this well is replacing.
The new source chemistry submitted for the Town Well REPL-1 shows elevated concentrations of chloride, sulfate, and total dissolved solids (TDS). The TDS level in the replacement well
is 1,240 mg/L and the secondary maximum contaminant level for TDS is 1,000 mg/L. A blending plan was submitted with the plans and specifications for the replacement well. The blending
plan included calculations showing that when the replacement well water is mixed with the spring water in the storage tanks, the blended TDS concentration will be 954 mg/L. The blending
plan calculations were done considering the worst-case scenario of the spring flow at its lowest rate.
We have received the following information for the Town Well REPL-1 (WS005):
Certification of well seal.
Well driller’s report (well log).
Aquifer drawdown test results (constant-rate test).
New Source Chemical Analyses of the well water, only Inorganics and Metals for a replacement well.
Plans and specifications for equipping the well.
Pump motor horsepower and calculated discharge rate
Well head discharge piping.
Well house design
We have completed our review of the plans and specifications, stamped and signed by James Saunders, P. E., and dated March 19, 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 Town Well REPL-1 are hereby approved.
This approval pertains to construction only. An Operating Permit must be obtained from the Director before Town Well REPL-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.
Drinking Water Source Protection Requirements
The Drinking Water Source Protection (DWSP) plan was due August 22, 2023. If you have any questions about Source Protection requirements contact Melissa Noble at [phone] or via
email at [e-mail].
Source Monitoring Requirements
Upon the issuance of an operating permit, pursuant to R309-215-6(2)(a), the efficacy of blending will be evaluated through quarterly TDS sampling. Samples shall be collected at the sampling
location located on the east shoulder of Highway 125 at the Central Utah Canal Crossing. This location is understood to represent the combined source water downstream of the storage
tanks used for blending (identified as ST001 ST002 ST003 and ST004) while being located upstream of all service connections.
A new facility has been created to represent this location. It is identified as “TDS Blending 02 03 05” in the Divisions database and has been assigned the facility ID of TP003. Please
label all samples collected from this location as “TP003” on the laboratory chain of custody to ensure sample results are reported.
Since this location is upstream of any service connections, all chemical samples required under R309-205 can be collected from this location. Upon the issuance of an operating permit
the monitoring requirements previously assigned to the springs (SS026) and the Town Well (WS001) will be moved to the TDS Blending 02 03 05 (TP003) location. Please ensure that when
chemical sampling is conducted that springs and Town Well REPL-1 are supplying water to this location. Please contact David Kruse at [e-mail] or 385-566-7789 with any questions
related to the source chemical monitoring requirements for this system.
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.
