Subject: Monitoring Requirement Changes – Disinfection Byproducts and Lead & Copper,
Winchester Hills Water Co (UTAH27049)

Dal Liston:

Due to recent updates to your system’s population count, your water monitoring requirements for
Disinfection Byproducts (DBPs) and Lead and Copper have changed as described below:

Disinfection Byproducts Monitoring
Winchester Hills Water Co has been moved to annual monitoring for DBPs based on updates to the
population count served by the water system. This means the system must collect one (1) DBP sample
every year. Each DBP sample must be a paired sample analyzed for both haloacetic acids and
trihalomethanes. The next samples must be collected during the July 1 - September 30, 2024, monitoring
period. The system should use the DBP sample sites listed in the attached monitoring schedule. If the
system would like to use different sample sites it needs to submit an updated DBP sample site plan using
the attached sample site plan template. Please contact Luke Treutel at [e-mail] or at (385) 258-
6084 if you have any questions regarding DBP monitoring and reporting.

Lead & Copper Monitoring
The lead and copper monitoring requirements for Winchester Hills Water Co have changed based on an
updated population of 950. This means the system must collect 10 first-draw lead and copper samples
every 3 years. The next round of samples must be collected during the June 1, 2026 - September 30, 2026

monitoring period. Please contact Dylan Martinez at [e-mail] or at [phone] if you
have questions about lead and copper monitoring and reporting requirements.

Your monitoring requirements, including these updated requirements, are available to you online at
waterlink.utah.gov. Additionally, a copy of your system’s monitoring schedule has been enclosed.

Thank you for your efforts to maintain safe drinking water.

Sincerely,
Mark Berger
Monitoring and Standards Section Manager

Stage 2 Disinfectant Byproduct (DBP) Sampling Plan
In accordance with State of Utah Rule R309-210-10(3): Any Community (COM) or Non-Transient Non-Community
(NTNC) drinking water system that regularly applies a chemical disinfectant must develop and implement a DBP
monitoring plan. The system must maintain current version of the plan on file and submit a copy of 1) the monitoring
plan, 2) a schematic of the distribution system, and 3) the justification for site selection (IDSE water, modeling analysis,
etc.) to the Division of Drinking Water.

SITE SELECTION INFO
Associated Rules:
R309-210-9(2)(b)(i)(Q): A dual sample set (i.e., a TTHM and an HAA5 sample) must be
taken at each monitoring location during each monitoring period.
Associated Info:
Disinfection By Product Sampling
schedules are based on
population and source water
type. DBPs may be required
quarterly, annually, or every
three years. For a complete list of
possible schedules please see
associated DBP handout.
•One dual sample set must be taken at the
highest TTHM (trihalomethanes) sampling
site, at a location that represents
maximum residence time; typically in the
furthest reaches of your distribution
system, or where water is oldest.
This location is denoted as MR001.
•One dual sample set must be taken
at the highest HAA5 (haloacetic
acids) sampling site, at a location
that represents the average
residence time; typically located mid
distribution system
This location is denoted as MD001.
R309-210-10(3)(ii):
•Water system must identify which locations will be used for compliance monitoring
by alternating selection of locations representing high TTHM and high HAA5 levels
until the required number of compliance monitoring locations have been identified.
