EPA's federal records list this system as inactive in 2021; the record below is historical.

As of August 1, 2026, its federal record holds 23 entries between 1996 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.

Of the 23, 19 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 synthetic organic chemicals, the Lead and Copper Rule, and the Total Coliform Rules.
