Subject: Notice of Increased Monitoring for Swiss Alpine Water Co, UTAH26049

Kim Townsend:

According to the Division of Drinking Water’s (the Division) records, the Swiss Alpine Well
(listed as WS002 in the Divisions database) detected Gross Alpha Particle Activity at levels of 31
pCi/L on August 21, 2023. The Maximum Contaminant Level (MCL) for this contaminant is 15
pCi/L. As a result of this, this source is now subject to increased monitoring in accordance with
R309-205-7(b)(iv). Compliance with the Gross Alpha Particle Activity MCL will be determined
by the Running Annual Average (RAA) of the samples collected at the Swiss Alpine Well
(WS002). Currently, the RAA at the Swiss Alpine Well (WS002) is 14 pCi/L. If at any point the
RAA is greater than 15 pCi/L, a MCL violation will be issued, and public notice will be required.

Swiss Alpine Well (WS002) is now required to be sampled each calendar quarter that the facility
is running for Radium 226, Radium-228, Gross Alpha Particle Activity, and Combined Uranium.
Presented below are the complete monitoring requirements for this facility.
