As of August 1, 2026, its federal record holds 5 entries between 1994 and 1998, all of which EPA lists as closed. Nothing has been added since 1998.
All 5 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 volatile organic chemicals.
