As of August 1, 2026, its federal record holds 1 entry in 2005, all of which EPA lists as closed. Nothing has been added since 2005.

All 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.

It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits.
