LUTHER WATER SUPPLY is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, formerly serving 158 people from groundwater.

EPA's federal records list this system as inactive in 1991; the record below is historical.

As of August 1, 2026, its federal record holds 12 entries between 1979 and 1990, all of which EPA lists as closed. Nothing has been added since 1990.

Of the 12, 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 inorganic chemicals and the Lead and Copper Rule.
