EPA's federal records list this system as inactive in 1997; the record below is historical.
As of August 1, 2026, its federal record holds 4 entries between 1992 and 1997, all of which EPA lists as closed. Nothing has been added since 1997.
Of the 4, 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.
