CRESTBROOK S/D is one of 698 community water systems in Alaska in the 500 or fewer people size category, formerly serving 146 people from groundwater.

EPA's federal records list this system as inactive in 1997; the record below is historical.

As of August 1, 2026, its federal record holds 15 entries between 1985 and 1992, all of which EPA lists as closed. Nothing has been added since 1992.

All 15 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 volatile organic chemicals, inorganic chemicals, and the Radionuclides and Revised Rad Rule.
