Subject: Quarterly Arsenic Monitoring for 2nd Quarter 2024

Dear David:

This report contains the results of our Arsenic Monitoring Program for the 2nd quarter of 2024.

Samples were collected from 3 sites in Blue Mountain South water system 11066. 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
