Drinking Water Sample Results

DEC has received multiple public records act requests for PFAS analytical results from drinking water wells that have been sampled throughout the state. In order to provide transparency and share information, DEC is making these PFAS drinking water sample results available. The files below include drinking water sample results that have been collected and analyzed for PFAS in each of these Alaska communities. For all drinking water wells where PFAS were found above the EPA Lifetime Health Advisory, alternative drinking water or treated water is being provided.

Please be aware of the file size when downloading and opening the documents. Some information contained in these files has been redacted for privacy reasons. Please note this data may not represent all areas potentially affected by PFAS or all drinking water wells located within known PFAS-affected areas.

Some of the selected drinking water wells in the following locations that have been sampled for PFAS have contained concentrations ABOVE the EPA Lifetime Health Advisory level for PFOA + PFOS of 70 parts per trillion:

Selected drinking water wells in the following locations have been sampled and all results to date have been BELOW the EPA Lifetime Health Advisory level for PFOA + PFOS of 70 parts per trillion:

An inventory of all sites where PFAS contamination has been identified in soil and water can be found here: PFAS Sites in Alaska (XLS). This list is updated monthly, or as new sites are added. Information about these sites, including environmental documents and project-specific results that are available, may be accessed through the Contaminated Sites Database by entering the site's Hazard ID, shown on the MS Excel spreadsheet. Other drinking water data may be available on the Drinking Water database.

For questions on these data or the associated sites please contact John Halverson at 907-269-7545. Please continue to check back as we update this information.

*Utilizes a surface water source with concentrations above the LHA, however the treated drinking water samples have consistently been below the LHA.
