LERNA is one of 1,572 community water systems in Illinois in the 500 or fewer people size category, formerly serving 350 people from groundwater.

EPA's federal records list this system as inactive in 2023; the record below is historical.

As of August 1, 2026, its federal record holds 10 entries between 1977 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.

Of the 10, 7 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 Consumer Confidence Rule, the Total Coliform Rules, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
