PARNELL WATER SUPPLY is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, formerly serving 194 people from groundwater.

EPA's federal records list this system as inactive in 2022; the record below is historical.

As of August 1, 2026, its federal record holds 18 entries between 1988 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.

Of the 18, 15 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, the Lead and Copper Rule, and the Total Coliform Rules.
