Dear Dawna, Subject: RTCR Level 2 Assessment South Robinson Springs Water Users UTAH15018
I would like to thank John Pincock, Jason Taylor and yourself for taking the time to meet with me
on January 15th, 2025, for a Level 2 Assessment (L2) of your water system. Your willingness to accommodate this request is greatly appreciated. Observations:

This site visit was triggered by multiple Routine and Repeat TC+EC- samples February, March April 2024 and Routine TC+EC- August 2024 with Repeats taken in September 2024. Spring Source samples during these events have been TC-EC-.
South Robinson Springs Water Users is a community water system with 10 connections and a
population of 17 people. The system consists of a spring source flowing into a 20,000-gallon tank gravity supplying the 10 service connections. Mainline is small 11/2” galvanized pipe which system has had to replace parts of this line as it has failed. A portion of main line ends at a service connection not being used. (connected to Morgan City
system)
System Indicated samples were taken from premise plumbing in old houses with galvanized pipes. Conclusions:

1. TC+ samples were likely due to stagnant water /Old Water age, system indicated very little water is used during this time of year and only 5 or 6 homes are even occupied during the last few years.

2. 20 K storage tank is very old and at the time of the assessment had an extensive inspection and repair process performed by Potable Divers. It is highly likely based on what the divers found and repaired; this tank could have contributed to the positive samples. This
tank is in the spring area and could also be considered a spring collection box as well.
Recommendations:

1. Conduct a distribution system O & M disinfection and flushing of system, following AWWA C-651 standards. 2. Collect Investigative Bacteriological samples from storage tank to determine if the tank is
having problems.
3. Follow sanitary sampling protocol of sufficient flushing and disinfection, using a strong chlorine-based solution (applying, allowing contact time, flushing, sample collection).
4. Avoid taking samples from taps which are supplied by water treatment devices. (Water
softeners, Filters, etc.) 5. Complete a revised RTCR sample site plan, assigning sites that are not at the end of the system and are not vacant homes.

6. Inspect and Clean Storage tank on a regular basis, Disinfect as per AWWA C651 standards as an O& M procedure.
