Source Water Assessment Summary

Help with this page
Please read: Information provided on this page is automatically generated from a database containing the results from the Source Water Assessment (SWA) report for public water system (PWS) sources (i.e., wells or intakes). If results are not displayed below, it's likely because a SWA report was not completed. Many PWS sources that became active after 2006 do not have a SWA report and the State of Alaska Drinking Water Program is no longer completing new reports or revising old reports. While SWA reports are no longer being completed, PWS owners, operators, and communities are encouraged to develop Drinking [Source] Water Protection Plans to help minimize the risk of potential contamination. See the Drinking Water Protection website for more information.
The UNALASKA WATER SYSTEM   (AK2260309) located in ALEUTIAN WEST is a Community public water system consisting of [4] active sources, intakes, or wells.
