KALAUPAPA NHP is one of 87 community water systems in Hawaii in the 500 or fewer people size category, serving 110 people from groundwater.

As of August 1, 2026, its federal record holds 9 entries between 2005 and 2022, of which 1 remains open; none are health-based.

All 9 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 Lead and Copper Rule, 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.
