EPA's federal records list this system as inactive in 2017; the record below is historical.
As of August 1, 2026, its federal record holds 15 entries between 2003 and 2015, all of which EPA lists as closed. Nothing has been added since 2015.
Of the 15, 14 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 Total Coliform Rules, and the Lead and Copper Rule.
