HONOKOHAU is one of 87 community water systems in Hawaii in the 500 or fewer people size category, serving 42 people from groundwater.

As of August 1, 2026, its federal record holds 12 entries between 1981 and 2011, all of which EPA lists as closed. Nothing has been added since 2011.

Of the 12, 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 Surface Water Treatment Rules and the Total Coliform Rules.

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.
