Y/FLATS SD - CIRCLE SCHOOL is one of 698 community water systems in Alaska in the 500 or fewer people size category, formerly serving 27 people from groundwater.
EPA's federal records list this system as inactive in 1995; the record below is historical.
As of August 1, 2026, its federal record holds 24 entries between 1986 and 1993, all of which EPA lists as closed. Nothing has been added since 1993.
Of the 24, 19 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, inorganic chemicals, and the Total Coliform Rules.
