CHENOWITH PUD - COLUMBIA CREST is one of 1,168 community water systems in Oregon in the 500 or fewer people size category, formerly serving 50 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 61 entries between 1976 and 2007, all of which EPA lists as closed. Nothing has been added since 2007.

Of the 61, 57 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, inorganic chemicals, and volatile organic chemicals.
