CEDAR KNOLL CARE CENTER is one of 1,316 community water systems in Michigan in the 500 or fewer people size category, formerly serving 169 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 7 entries between 2003 and 2006, all of which EPA lists as closed. Nothing has been added since 2006.
Of the 7, 6 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, inorganic chemicals, and the Consumer Confidence Rule.
