As of August 1, 2026, its federal record holds 4 entries between 1977 and 2024, all of which EPA lists as closed.
Of the 4, 3 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 Public Notice Rule and Revised PN Rule, the Stage 2 Disinfectants and Disinfection Byproducts Rule, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
