EPA's federal records list this system as inactive in 2022; the record below is historical.

As of August 1, 2026, its federal record holds 25 entries between 1987 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.

Of the 25, 24 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 volatile organic chemicals, inorganic chemicals, and the Total Coliform Rules.
