As of August 1, 2026, its federal record holds 3 entries between 1997 and 2015, all of which EPA lists as closed. Nothing has been added since 2015.
Of the 3, 2 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 Groundwater Rule, inorganic chemicals, and the Total Coliform Rules.
