EPA's federal records list this system as inactive in 2025; the record below is historical.
As of August 1, 2026, its federal record holds 2 entries between 1986 and 2006, all of which EPA lists as closed. Nothing has been added since 2006.
All 2 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 and inorganic chemicals.
