FOUR LAKES SUBDIVISION is one of 1,572 community water systems in Illinois in the 500 or fewer people size category, formerly serving 12 people from groundwater.

EPA's federal records list this system as inactive in 2006; the record below is historical.

As of August 1, 2026, its federal record holds 18 entries between 1977 and 2006, all of which EPA lists as closed. Nothing has been added since 2006.

Of the 18, 3 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 Radionuclides and Revised Rad Rule, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Total Coliform Rules.
