NORTH CORVALLIS MHP-WELL #1 is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, serving 100 people from groundwater.

As of August 1, 2026, its federal record holds 59 entries between 1992 and 2025, of which 1 health-based item remains open, alongside 1 other open entry.

Of the 59, 55 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 Total Coliform Rules.
