System facts

System ID (PWSID): AK2222830
System type: Community Water System
Population served: 35
Service connections: 14
Ownership: privately owned
Water source: groundwater (wells)

KOHRING S/D is one of 698 community water systems in Alaska in the 500 or fewer people size category, formerly serving 35 people from groundwater.

EPA's federal records list this system as inactive in 2007; the record below is historical.

As of August 1, 2026, its federal record holds 64 entries between 1988 and 2006, all of which EPA lists as closed. Nothing has been added since 2006.

All 64 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 Total Coliform Rules.
