Subject: Reduced Disinfection Byproduct Monitoring for Boyer Hill Military Housing, UTAH06048

This letter is to inform you that the Utah Division of Drinking Water has changed the disinfection
byproduct (DBP) sampling schedule for Boyer Hill Military Housing because the water system now
qualifies for reduced DBP monitoring based on sample results from the previous year.

DBP Monitoring Requirements
The water system is now required to collect one (1) DBP sample per 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. The specific sites that need to be
monitored can be found on the system’s WaterLink page under the water monitoring section.

If you have any questions, please contact Luke Treutel at [phone] or [e-mail].

Sincerely,
Mark Berger
Monitoring & Standards Section Manager
