The population count was changed from 435 to 557 during the most recent sanitary survey. This results in the following changes to your system’s sampling requirements: Disinfection Byproducts (DBPs) Sampling The water system’s Disinfection Byproducts (DBP) sampling requirement has changed. Previously, the water system was required to collect one sample every three years. The system is now required to collect one (1) sample set of DBPs 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. For any questions regarding the DBP rule contact Luke Treutel at (385) 258-6084 or ltreutel@utah.gov. 195 North 1950 West • Salt Lake City, UT Mailing Address: P.O.

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. BASIC WATER SYSTEM INFO Water System Name: Water System #: Residual Disinfectant Type: ☐ Chlorine ☐ Chlorine Dioxide ☐ Ozone # of Service Connections: Population (# of customers): Sampling Schedule ( # of sampling locations): Per Quarter Per Year 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. Water system sampling schedules with sampling locations and details are available at any time at WaterLink.utah.gov SAMPLES Sample Code Specific sampling location ADDRESS Site Characteristics / Site Selection Justification (check those that apply) MR001 MR002 MR003 MR004 ☐Highest TTHM/HAA5 in prior data☐Endpoint of distribution system and/or maximum water age☐Other: MD001 MD002 MD003 MD004 ☐Highest TTHM/HAA5 in prior data☐Midpoint of a large distribution system☐Endpoint of distribution system and/or maximum water age☐Other: Annual samples must be collected within a specific time frame in accordance with State of Utah Rules R309-210-10(2)(a)(ii)(N): All systems must monitor during months of highest DBP concentrations.
