Kauai County releases 2026 water quality report for 2025 results

Kauai County released its 2026 Water Quality Report on July 1, giving residents the annual public checkup on drinking water served across the island. The report covers Jan. 1 through Dec. 31, 2025 and is available in print and online.

The Līhue-Kapaa Water System report was produced under the federal Safe Drinking Water Act and covers where the water comes from, what it contains and how it compared with U.S. Environmental Protection Agency and state standards. Kauai’s potable water supply meets or exceeds state and federal standards for clean, safe drinking water.

For households in Līhue, Kapaa, Kōloa, Hanapēpē, Kekaha and Hāena, the report is the county’s main annual public record for tracking how the island’s drinking water performed over the prior year. It also gives customers a way to compare this year’s findings with the previous report, which covered Jan. 1 through Dec. 31, 2024 and was published on June 26, 2025. No water-quality violation or emergency was announced with this year’s release.

Source water assessments are completed each year by the State of Hawaii Department of Health and the University of Hawaii. The Department of Water is a semi-autonomous agency governed by the Kauai Board of Water Supply, a seven-member board that meets on the third Thursday of each month. The department is responsible for nine independent water systems from Kekaha to Hāena.
