OAK RIDGE ESTATES is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, formerly serving 270 people from surface water.
EPA's federal records list this system as inactive in 2019; the record below is historical.
As of August 1, 2026, its federal record holds 10 entries between 1998 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.
Of the 10, 5 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, the Total Coliform Rules, and the Lead and Copper Rule.
