Dear Mr. Madsen,
Subject: RTCR Level 2 Assessment Spring City UTAH20008
I would like to thank you for taking the time to meet with me on November 29, 2024, for a Level
2 Assessment (L2) of your water system. Your willingness to accommodate this request is greatly
appreciated.
Observations:
The initiation of this Level 2 (L2) assessment is prompted by multiple positive Total Coliform
(TC+) results identified during routine sampling, as well as follow-up samples required under the
Revised Total Coliform Rule (RTCR) in June, July, and October 2024. In response, the Spring
City Water System is implementing significant infrastructure upgrades, including the installation
of a chlorine disinfection system (CL2 chlorinator) and the construction of a new storage facility,
the Canyon Tank, which is expected to be operational by October 2025. The chlorination system
will work in tandem with the new tank, and will be boosted, ensuring the distribution of
chlorinated water from the Canyon Tank to the upper two tanks within the system. This upgrade
will enable consistent chlorination throughout the entire water system.
Conclusions:
The TC+ samples have consistently come from the lower zone of the system. Mr. Madsen noted
that he is unable to spill the Yard Tank, preventing the removal of biofilm accumulating on the
water's surface, which may be harboring TC+ bacteria in the lower zone. This issue is one of the
primary reasons the Yard Tank will be decommissioned and replaced by the new Canyon Tank.
When the installation of the chlorinator is complete, the system will eliminate concerns regarding
bacterial presence.

Recommendations:
Once the new chlorinator is up and operating on your water system we recommend implementing
a comprehensive and effective flushing plan to help remove biofilm from your system. This
process will address issues such as discolored water and the chlorine odor, while you continue
fine-tuning your chlorinators to achieve optimal performance.
