David Kruse Division of Drinking Water P.O. Box 144830 Salt Lake City Utah

Subject: Quarterly Arsenic Monitoring for 4th Quarter 2024 Dear David:
This report contains the results of our Arsenic Monitoring Program for the 4th quarter of 2024.
Samples were collected from 3 sites in Blue Mountain South water system 11066, 1 site in Skyline water system 01033. The analytical laboratory results and a summary of the arsenic field-testing data should have been sent to you from Chem-Tech Ford Laboratories.

All bacteriological sample results were absent from bacteria during this sampling period. The sampling results indicate that the point-of-use devices (RO units) are performing as designed and keeping the arsenic levels in compliance. It may be of interest to DDW these RO units are on a routine
maintenance schedule with our vendor and as needed throughout the year.
If you have any questions, please feel free to contact me at [phone]. Sincerely,

Clayton Terry LNM Sampling Technician
