MAUNALOA-KALUAKOI is one of 42 community water systems in Hawaii in the 501 to 3,300 people size category, serving 1,000 people from groundwater.

As of August 1, 2026, its federal record holds 23 entries between 1980 and 2022, of which 1 remains open; none are health-based.

Of the 23, 3 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, the Lead and Copper Rule, and the Stage 2 Disinfectants and Disinfection Byproducts Rule.

EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
