HARWOOD HEIGHTS is one of 248 community water systems in Illinois in the 3,301 to 10,000 people size category, serving 9,065 people from surface water.
As of August 1, 2026, its federal record holds 6 entries between 1992 and 1997, all of which EPA lists as closed. Nothing has been added since 1997.
Of the 6, 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 Lead and Copper Rule and the Total Coliform Rules.
