HICKORY ESTATES is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, formerly serving 48 people from groundwater.

EPA's federal records list this system as inactive in 2010; the record below is historical.

As of August 1, 2026, its federal record holds 31 entries between 1980 and 2010, all of which EPA lists as closed. Nothing has been added since 2010.

Of the 31, 26 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 volatile organic chemicals, the Total Coliform Rules, and inorganic chemicals.
