Dear Maria, Subject: RTCR Level 2 Assessment Woods Ranch UTAH11069
I would like to thank you for taking the time to meet with me on August 29th, 2024 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 TC+ EC+ Escherichia coli (E. coli) positive routine & repeat
samples in the distribution system. The spring source sample was TC-EC-. These samples were collected from the sample site plan yard hydrants.
Woods Ranch is a Transient Non-community seasonal water system consisting of a spring source,
2–1700-gallon storage tanks and 4 frost free hydrants for a picnic site.
Conclusions: 1. EC+ samples were likely caused by a contaminate entering the tank, either from the spring
source after rain fall (source sample TC-EC-) or from an unknown other pathway.
2. The spring area received a heavy rain event prior to these samples. The spring collection area showed evidence of run off.
3. Large tree stumps in spring collection area, although they appear to be dead, have root
systems which could impacted the spring collection area and potentially provide a pathway for contamination.
Recommendations:

1. Inspect and clean storage tank WS001 on a routine basis, disinfect tank per AWWA C651 Standards.
2. Consider changing source to permanent water hauling. This will require Division of Drinking Water (DDW) approval. Your current spring source is nearing a point to need a substantial redevelopment.
3. Follow DDW seasonal start up procedures for disinfection and flushing of system, ( Including line from spring to Tank ) it is recommended disinfecting your system at shutdown to help with biofilm issues. 4. Follow sanitary sampling protocol for sufficient flushing and disinfection. Use a strong
chlorine-based solution allowing sufficient contact time, flushing, sample collection.
5. Collect investigative samples periodically, specifically after rain events from the spring source when the spring source is brought online.
Deficiencies identified during the L2 Assessment: No New Deficiencies
