DAKOTA MHP is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, formerly serving 32 people from groundwater.

EPA's federal records list this system as inactive in 2006; the record below is historical.

As of August 1, 2026, its federal record holds 6 entries between 1994 and 2004, all of which EPA lists as closed. Nothing has been added since 2004.

Of the 6, 5 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 Total Coliform Rules, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and inorganic chemicals.
