MCDOUGAL WATER SYSTEM is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, serving 60 people from groundwater.

As of August 1, 2026, its federal record holds 45 entries between 1996 and 2025, all of which EPA lists as closed.

Of the 45, 42 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 inorganic chemicals.
