Subject: Notice of Increased Monitoring and Confirmation Sampling Requirements for
Jordanelle SSD; UTAH26086
Max Covey: According to the Division of Drinking Water’s (the Division) records, thallium was recently
detected in the water leaving the Keetley WTP (TP003) at 0.0036 mg/L. The maximum contaminant level for thallium is 0.002mg/L. Pursuant to R309-205-5, the Keetley WTP (TP003) is now subject to confirmation sampling and increased monitoring requirements. Please collect a thallium sample from the Keetley WTP (TP003) as soon as possible and submit
the results to the Division. Additionally, the Keetley WTP (TP003) is now required to be sampled each quarter for thallium. Compliance with the thallium standard will be based on the running annual average (RAA). If the RAA for thallium is greater than 0.002 mg/L after one year of quarterly sampling, the system will
be considered in violation of the thallium standard and public notice will be required.
The current monitoring requirements for the Keetley WTP (TP003) are given below. An updated monitoring schedule can be viewed anytime online at waterlink.utah.gov.
