Drinking Water Rule Amendments

This process governs amendments to Hawaii's administrative rules for public drinking water systems, covering standards for contaminants, treatment, monitoring, and reporting. The Hawaii Department of Health oversees rulemaking to ensure drinking water meets federal Safe Drinking Water Act requirements and state standards. Public comment periods allow residents and utilities to weigh in before rules take effect.

The rules set here determine the safety standards for the water coming out of your tap across the state. Residents can participate by submitting written comments or testifying at public hearings during the rulemaking process.
