The City water system’s Drinking Water Quality Report, also known as Consumer Confidence Report or CCR, for the year of 2025 has been mailed out to every water customer in the City’s service area.
Your tap water delivers more value than any other water available to consumers. Consider the many ways that we use water:
In The Dalles, you can drink and wash your hands in water from any home faucet and public tap with a high assurance of safety; as shown in this annual report.
Fire protection
The City water system provides water where firefighters need it – when they need it
Support for the economy
Local businesses and industries depend upon a safe, reliable water supply.
The overall quality of life we enjoy
From your morning shower and cup of coffee to washing your supper dishes, safe tap water that you can count on is more than a convenience; it is central to our everyday lives.
Additional Water Quality Testing
During 2025, additional water testing was required ahead of pumping excess surface water into the new Aquifer Storage and Recovery (ASR) system. Water was tested by state- and federal-certified laboratories for many possible contaminants, including bacteria, turbidity, inorganic, and organic chemicals, like the disinfection by-products. Chlorine dioxide and bromate were detected in excess of maximum contaminant level (MCL) in the first quarter of 2025. They were not detected in excess of the MCL in the
following three quarters of 2025. Detection of these materials in excess of the maximum contaminant level is not an emergency. If it had been an emergency, you would have been notified within 24 hours.
The City will continue to monitor
No root cause for the detection of these materials has been determined at this time. Therefore, the City will add these materials to the quarterly disinfection byproducts sample schedule in addition to ASR related sampling in 2026.
