Dear Mr. Goodman,
Subject: RTCR Level 2 Assessment Mt Tabby Springs Subdivision UTAH070009
On May 21, 2024, I met with Jack Distefano to conduct the Level 2 Assessment (L2) of your
water system. Your cooperation in facilitating this assessment is greatly appreciated.
Observations:
This Level 2 Assessment was triggered by multiple TC+/EC- samples since June of 2023. During
the past year, the routine bacteriological sample has been total coliform positive during every
month of operation.

Mt. Tabby Springs Subdivision is a Transient Non-Community water system located in Duchesne
County which provides water to approximately 219 recreational properties. This system operates
seasonally between May and September. The system consists of a spring source and a 103,000-
gallon storage tank.

An MPA test performed in May of 2024 showed the spring be at low risk for surface water
influence, although there was water flowing across the surface of the collection area . This
condition was also observed in the fall of 2023. It is likely that the increased runoff flow in 2023
has opened new pathways for the water to exit the toe of the bluff at the surface.

The population of crickets which were observed in 2023 are also still present. The presence of
these crickets is a likely contributor to the TC+ samples, either from the crickets themselves, or
that pathway they are using to enter the spring box is also allowing other contamination to
enter.

During the site visit, it was expressed that there was a plan in place to drain off the surface water
from the collection area and under the road.

Conclusions:
1. The most likely cause of the unsatisfactory samples seems to be a change in water flow
caused by increased snowpack and runoff during the winter of 2022/2023.

2. The next most likely cause would be a colony of crickets living inside the spring collection
box. This could be the most likely cause and these crickets should be eliminated as soon as
possible.

Deficiencies:

No new deficiencies were assigned during this assessment.

Recommendations:
1. Regular inspections of the spring collection box to ensure all openings have been sealed and the
crickets have been removed.
2. Monthly source assessment samples to determine source water quality.
4. Draining of the surface water away from the spring collection area.
Please contact me at 801-419-6785 or [e-mail], with any questions or if we can be of
further assistance.

Sincerely,

Ryan Dearing
