AVION WC - CHAPARRAL is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, serving 470 people from groundwater.
As of August 1, 2026, its federal record holds 26 entries between 1976 and 2014, all of which EPA lists as closed. Nothing has been added since 2014.
All 26 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, the Total Coliform Rules, and volatile organic chemicals.
