BEACON WATER SUPPLY is one of 403 community water systems in Iowa in the 501 to 3,300 people size category, formerly serving 504 people from surface water.
EPA's federal records list this system as inactive in 2020; the record below is historical.
As of August 1, 2026, its federal record holds 3 entries between 1991 and 2006, all of which EPA lists as closed. Nothing has been added since 2006.
All 3 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.
