ETHAN ALLEN SCHOOL is one of 1,289 community water systems in Wisconsin in the 500 or fewer people size category, formerly serving 15 people from groundwater.
EPA's federal records list this system as inactive in 2011; the record below is historical.
As of August 1, 2026, its federal record holds 8 entries between 1988 and 2010, all of which EPA lists as closed. Nothing has been added since 2010.
Of the 8, 6 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, volatile organic chemicals, and the Total Coliform Rules.
