ADA is one of 56 community water systems in Oklahoma in the 10,001 to 100,000 people size category, serving 22,600 people from groundwater.
As of August 1, 2026, its federal record holds 7 entries between 2002 and 2025, all of which EPA lists as closed.
Of the 7, 4 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves the Lead and Copper Rule, the Total Coliform Rules, and the Consumer Confidence Rule.

What is a Consumer Confidence Report?
- A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
