PALOS HILLS is one of 225 community water systems in Illinois in the 10,001 to 100,000 people size category, serving 18,530 people from surface water.
As of August 1, 2026, its federal record holds 3 entries between 1992 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.
Of the 3, 2 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 and the Lead and Copper Rule.
