As of August 1, 2026, its federal record holds 14 entries between 1979 and 2024, all of which EPA lists as closed.
Of the 14, 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 the Stage 2 Disinfectants and Disinfection Byproducts Rule, inorganic chemicals, and the Total Coliform Rules.
