GREYHAWK is one of 969 community water systems in Idaho in the 500 or fewer people size category, formerly serving 60 people from groundwater.
EPA's federal records list this system as inactive in 1992; the record below is historical.
As of August 1, 2026, its federal record holds 4 entries between 1979 and 1992, all of which EPA lists as closed. Nothing has been added since 1992.
Of the 4, 1 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 inorganic chemicals and the Total Coliform Rules.
