As of August 1, 2026, its federal record holds 4 entries between 1993 and 2021, all of which EPA lists as closed. Nothing has been added since 2021.
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 inorganic chemicals, the Consumer Confidence Rule, and the Total Coliform Rules.
