System type: Community Water System
Population served: 0

DUPLICATE OF 234352 DO NOT USE formerly served 0 people from groundwater.

EPA's federal records list this system as inactive in 2007; the record below is historical.

As of August 1, 2026, its federal record holds 52 entries between 1992 and 2007, all of which EPA lists as closed. Nothing has been added since 2007.

Of the 52, 51 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, volatile organic chemicals, and the Total Coliform Rules.
