MACON PWS is one of 140 community water systems in Missouri in the 3,301 to 10,000 people size category, serving 5,489 people from surface water.

As of August 1, 2026, its federal record holds 26 entries between 1983 and 2025, of which 1 remains open; none are health-based.

Of the 26, 25 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 volatile organic chemicals, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and synthetic organic chemicals.

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.
