GEMSTONE ESTATES is one of 698 community water systems in Alaska in the 500 or fewer people size category, serving 75 people from groundwater.
As of August 1, 2026, its federal record holds 7 entries between 2010 and 2012, all of which EPA lists as closed. Nothing has been added since 2012.
All 7 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 and inorganic chemicals.
