MADRU SUBDIVISION is one of 1,399 community water systems in Ohio in the 500 or fewer people size category, formerly serving 66 people from groundwater.

EPA's federal records list this system as inactive in 1992; the record below is historical.

As of August 1, 2026, its federal record holds 12 entries between 1988 and 1991, all of which EPA lists as closed. Nothing has been added since 1991.

All 12 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 and synthetic organic chemicals.
