System type: Community Water System
Population served: 239
Service connections: 2
Ownership: privately owned

ST MARYS ALZHEIMERS CENTER is one of 1,399 community water systems in Ohio in the 500 or fewer people size category, formerly serving 239 people from groundwater.

EPA's federal records list this system as inactive in 2025; the record below is historical.

As of August 1, 2026, its federal record holds 77 entries between 1998 and 2024, all of which EPA lists as closed.

Of the 77, 69 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 volatile organic chemicals, the Consumer Confidence Rule, and the Total Coliform Rules.
