FLINT RIDGE RURAL WATER DISTRICT is one of 511 community water systems in Oklahoma in the 501 to 3,300 people size category, formerly serving 1,500 people from surface water.

EPA's federal records list this system as inactive in 2021; the record below is historical.

As of August 1, 2026, its federal record holds 15 entries between 1993 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.

Of the 15, 10 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 Surface Water Treatment Rules, the Total Coliform Rules, and the Consumer Confidence Rule.
