LONE OAK ESTATES is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, serving 258 people from groundwater.

As of August 1, 2026, its federal record holds 23 entries between 2001 and 2025, all of which EPA lists as closed.

Of the 23, 19 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 synthetic organic chemicals, volatile organic chemicals, and the Consumer Confidence Rule.
