MADISON EST. WATER ASSOC is one of 1,399 community water systems in Ohio in the 500 or fewer people size category, formerly serving 60 people from groundwater.

EPA's federal records list this system as inactive in 1998; the record below is historical.

As of August 1, 2026, its federal record holds 60 entries between 1986 and 1998, all of which EPA lists as closed. Nothing has been added since 1998.

Of the 60, 48 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, synthetic organic chemicals, and inorganic chemicals.
