Subject: Public Drinking Water Monitoring Requirements for Bridgerland Water Co,
System #17001

Dear Jo Heniger:

According to the Division of Drinking Water’s records, Bridgerland Water Co will now be
receiving chlorinated water from Garden City through the consecutive connection between the
two water systems. As a result, Bridgerland Water Co is now required to monitor for
Disinfection Byproducts (DBPs) and chlorine residuals in the distribution system. The new
monitoring requirements are as follows:

DBP Monitoring & Reporting Requirements
The water system is now required to collect one (1) DBP sample every year. Each sample must
be a dual sample set of total trihalomethanes (TTHMs) and haloacetic acids (HAA5). The next
DBP samples must be collected during the July 1 – September 30, 2025, monitoring period.

DBP Sample Site Plan Submission
The system must submit a DBP sample site plan to the Division within 30 days of this letter. The
plan must include at least one (1) sample site. A sample site plan template with instructions has
been enclosed.

Chlorine Residual Monitoring & Reporting Requirements
The water system must take a minimum of three (3) chlorine residual samples per week at
varying locations throughout its distribution system (DS001). A chlorine residual must be taken
in conjunction with the monthly total coliform sample collected from the distribution system.
This means that eleven (11) additional chlorine residuals need to be taken from the distribution
system per month, given that the system will take one residual reading with the monthly total
coliform sample. Chlorine residuals must be measured in the field using a chlorine test kit.
Distribution system chlorine residual monitoring results are due quarterly and must be submitted
no later than 10 days after the end of the quarter. The residuals must be submitted via an online
form found at mrdl.utah.gov.

You will find a current copy of your complete monitoring schedule at waterlink.utah.gov by
selecting your system and then selecting Water Monitoring under Water System Reports. If you
have questions concerning these monitoring and reporting requirements, please contact Luke
Treutel at [phone] ([e-mail]).

Sincerely,
Mark Berger
Monitoring & 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.

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.
