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.

ESSEX PWS is one of 1,412 community water systems in Missouri in the 500 or fewer people size category, serving 399 people from groundwater.

As of August 1, 2026, its federal record holds 11 entries between 2011 and 2025, all of which EPA lists as closed.

Of the 11, 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 Groundwater Rule, the Total Coliform Rules, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
