As of August 1, 2026, its federal record holds 2 entries between 1992 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
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 synthetic organic chemicals and the Total Coliform Rules.
