EXETER-MERRITT WATER COOP is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, serving 820 people from groundwater.

As of August 1, 2026, its federal record holds 15 entries between 1994 and 2024, all of which EPA lists as closed.

Of the 15, 10 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 Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.

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.
