As of August 1, 2026, its federal record holds 14 entries between 1991 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
Of the 14, 13 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, the Total Coliform Rules, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
