This letter serves as notification that quarterly monitoring of Radionuclides at the Flat Canyon Well (identified as WS003) is no longer required. Based on results obtained through initial monitoring, the Flat Canyon Well (WS003) qualifies for reduced monitoring in which one radionuclide sample is due in every nine-year compliance cycle.
The next radionuclide sample from the Flat Canyon Well (WS003) is due sometime between January 1, 2029, and December 31, 2037.

Additionally, the Division has resources to assist water systems in completing the PFAS initial
monitoring requirements. For more information on the resources the division can provide related to PFAS initial monitoring please visit ddwpfas.utah.gov. For PFAS related questions, please contact John Steffan at [e-mail] or [phone].
