SIDNEY CIRCLE HOMEOWNERS ASSN formerly served 0 people from groundwater.

EPA's federal records list this system as inactive in 2018; the record below is historical.

As of August 1, 2026, its federal record holds 50 entries between 1992 and 2018, all of which EPA lists as closed. Nothing has been added since 2018.

Of the 50, 40 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, volatile organic chemicals, and the Consumer Confidence Rule.
