CONWAY WS is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, formerly serving 63 people from groundwater.

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 9 entries between 1986 and 1989, all of which EPA lists as closed. Nothing has been added since 1989.

All 9 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, the Lead and Copper Rule, and the Radionuclides and Revised Rad Rule.
