CENTRAL IA WATER ASSN (NEWTON) is among the 20 largest community water systems in Iowa, formerly serving 28,250 people from surface water.
EPA's federal records list this system as inactive in 2009; the record below is historical.
As of August 1, 2026, its federal record holds 3 entries between 1991 and 2007, all of which EPA lists as closed. Nothing has been added since 2007.
Of the 3, 1 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 and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
