As of August 1, 2026, its federal record holds 3 entries between 2017 and 2025, all of which EPA lists as closed.
Of the 3, 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.
