LAKE TRIO HOMEOWNERS ASSOCIATION is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, formerly serving 57 people from groundwater.
EPA's federal records list this system as inactive in 2001; the record below is historical.
As of August 1, 2026, its federal record holds 2 entries in 1980, all of which EPA lists as closed. Nothing has been added since 1980.
All 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 Radionuclides and Revised Rad Rule.
