What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. Alaska has 406 active community water systems, 31% of the state's 1,322 active systems. Groundwater under the influence of surface water is well or spring water that the regulator has found to be affected by nearby surface water, so it is regulated under the surface-water treatment rules. 28 Alaska systems (2.1%) list groundwater under influence of surface water as their primary source.
Who owns and regulates Nikolski Village?
EPA lists Nikolski Village as Native American-owned. The AK state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 4 of the 6 active systems in Aleutians West Census Area County (67%) are also Native American-owned.
