COIN WATER SUPPLY is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, serving 176 people from groundwater.
As of August 1, 2026, its federal record holds 4 entries between 2011 and 2017, all of which EPA lists as closed. Nothing has been added since 2017.
Of the 4, 2 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 Stage 1 Disinfectants and Disinfection Byproducts Rule, the Consumer Confidence Rule, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.
