MADISON WATER DEPARTMENT is one of 558 community water systems in Ohio in the 501 to 3,300 people size category, formerly serving 2,500 people from surface water.

EPA's federal records list this system as inactive in 1991; the record below is historical.

As of August 1, 2026, its federal record holds 8 entries in 1988, all of which EPA lists as closed. Nothing has been added since 1988.

All 8 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 inorganic chemicals.
