As of August 1, 2026, its federal record holds 7 entries between 1996 and 2024, of which 1 remains open; none are health-based.
Of the 7, 6 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.
