KAUNAKAKAI serves 3,702 people from groundwater, placing it in the 3,301 to 10,000 people size category.

As of August 1, 2026, its federal record holds 10 entries between 1981 and 2008, all of which EPA lists as closed. Nothing has been added since 2008.

Of the 10, 7 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 synthetic organic chemicals, the Total Coliform Rules, and inorganic chemicals.

What is a Consumer Confidence Report?

A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
