EPA's federal records list this system as inactive in 2006; the record below is historical.

As of August 1, 2026, its federal record holds 2 entries between 1981 and 1993, all of which EPA lists as closed. Nothing has been added since 1993.

Of the 2, 1 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 Total Coliform Rules and the Radionuclides and Revised Rad Rule.
