Subject: Notice of Decreased Monitoring for Ash Grove Cement Company, UTAH12039

Cody Watkins:

This letter serves as notification that the arsenic and TDS monitoring requirement for the
Secondary Well (WS002) has been reduced to one sample for each parameter every three years.
Additionally, the quarterly TDS monitoring requirement for the Primary Well (WS001) has also
been reduced to one sample every three years.

The updated source chemical monitoring requirements are below, enclosed and are available to
view anytime online at waterlink.utah.gov. Please contact David Kruse at [e-mail] or
385-566-7789 for questions regarding the source chemical monitoring requirements for this
system.

Decreased Arsenic Monitoring
On March 20, 2024, the Secondary Well (WS002) detected arsenic at levels of 0.0121mg/L. The
Maximum Contaminant Level (MCL) for arsenic is 0.010mg/L. This result triggered increased
monitoring. Since then, four arsenic samples have been collected, with each sample result being
below the MCL. Pursuant to R309-205-5(3)(h), the Secondary Well (WS002) now qualifies for
reduced monitoring. Arsenic monitoring will be completed through routine sampling for the
analytes included in the inorganics and metals group.

The updated source chemical monitoring requirements for the Secondary Well (WS002) are given
below and are available to view anytime on waterlink.utah.gov.

PFAS Information and Resources
The EPA rule for PFAS requires that either method 533 or 537.1 version 2 are used for testing.
Please ensure that the chosen laboratory processes PFAS samples using one of these methods.
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].
