LOWER CHENOWITH WD is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, formerly serving 450 people from groundwater.

EPA's federal records list this system as inactive in 2007; the record below is historical.

As of August 1, 2026, its federal record holds 19 entries between 1976 and 2002, all of which EPA lists as closed. Nothing has been added since 2002.

Of the 19, 12 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 Total Coliform Rules, inorganic chemicals, and the Radionuclides and Revised Rad Rule.
