ROYAL OAKS ESTATES is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, formerly serving 865 people from groundwater.
EPA's federal records list this system as inactive in 2022; the record below is historical.
As of August 1, 2026, its federal record holds 7 entries between 1999 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.
Of the 7, 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 Consumer Confidence Rule and the Total Coliform Rules.
