NORTH FLORENCE IMPROVEMENT is one of 84 community water systems in Arizona in the 3,301 to 10,000 people size category, formerly serving 5,436 people from groundwater.

EPA's federal records list this system as inactive in 2010; the record below is historical.

As of August 1, 2026, its federal record holds 12 entries between 1986 and 2006, all of which EPA lists as closed. Nothing has been added since 2006.

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, the Total Coliform Rules, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
