OXFORD WATER SUPPLY is one of 403 community water systems in Iowa in the 501 to 3,300 people size category, serving 722 people from groundwater.
As of August 1, 2026, its federal record holds 11 entries between 1985 and 2024, all of which EPA lists as closed.
Of the 11, 7 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 Consumer Confidence Rule, inorganic chemicals, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
