As of August 1, 2026, its federal record holds 8 entries in 1979, all of which EPA lists as closed. Nothing has been added since 1979.
All 8 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 inorganic chemicals.
