ADAM'S MHP #1 is one of 1,399 community water systems in Ohio in the 500 or fewer people size category, formerly serving 100 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 17 entries between 1984 and 1986, all of which EPA lists as closed. Nothing has been added since 1986.
All 17 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 the Radionuclides and Revised Rad Rule.
