EPA's federal records list this system as inactive in 2020; the record below is historical.
As of August 1, 2026, its federal record holds 5 entries between 1980 and 2015, all of which EPA lists as closed. Nothing has been added since 2015.
Of the 5, 3 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 Consumer Confidence Rule, the Total Coliform Rules, and synthetic organic chemicals.
