WARSAW PWS is one of 489 community water systems in Missouri in the 501 to 3,300 people size category, serving 2,402 people from groundwater.

As of August 1, 2026, its federal record holds 6 entries between 1992 and 2010, all of which EPA lists as closed. Nothing has been added since 2010.

Of the 6, 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 Total Coliform Rules, the Consumer Confidence Rule, and the Lead and Copper 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.
