MULHALL is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, serving 225 people from groundwater.

As of August 1, 2026, its federal record holds 6 entries between 1997 and 2025, of which 1 remains open; none are health-based.

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.
