About Tap Water in Hawaii National Park, HI

Tap water in Hawaii National Park, HI ranks among the best in the state, maintaining a remarkable average water quality score of 86/100 across its 1 ZIP code. Based on recent EPA Safe Drinking Water Act compliance records, water provided by Hawaii Volcanoes Nat.park and other municipal suppliers has consistently met or exceeded federal safety standards. This top-tier "A" grade reflects strong infrastructure, diligent monitoring by Hawaii Department of Health, and low contaminant levels.

A major factor in Hawaii National Park's high rating is its flawless health-based violation record. Over the past 5 years of EPA tracking, local water systems have recorded zero health-based violations. This means that regulated contaminants—such as lead, arsenic, and harmful bacteria—have not exceeded the Maximum Contaminant Levels (MCLs) allowed by federal law. Drawing primarily from ground water, the city utilizes advanced filtration to maintain this standard.

Fortunately, the modeled risk for widespread lead exposure in Hawaii National Park's municipal water is relatively low compared to national averages. However, because lead typically enters drinking water through the corrosion of older, individual home plumbing rather than the main supply lines, residents in homes built before 1986 should still exercise caution by running the tap before use.
