PROSPECT HEIGHTS is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, serving 2,280 people from surface water.
As of August 1, 2026, its federal record holds 9 entries between 1987 and 2025, all of which EPA lists as closed.
Of the 9, 1 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 2 Disinfectants and Disinfection Byproducts Rule, and the Total Coliform Rules.
