MAUNAOLU is one of 87 community water systems in Hawaii in the 500 or fewer people size category, formerly serving 65 people from surface water.

EPA's federal records list this system as inactive in 2006; the record below is historical.

As of August 1, 2026, its federal record holds 2 entries between 1980 and 1985, all of which EPA lists as closed. Nothing has been added since 1985.

None of the 2 are monitoring or reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset; these involve water-quality, treatment, or public-notice findings instead. The record involves the Miscellaneous Other Rules.
