In 2015, the Air Force began sampling private wells in the Moose Creek community immediately downgradient of Eielson AFB. Sampling showed the presence of two PFAS chemicals — perfuorooctanoic acid (PFOA) and perfuorooctanesulfonic acid (PFOS)—at levels exceeding the Environmental Protection Agency’s Lifetime Health Advisory. The contamination likely originates from past aqueous flm forming foam (AFFF) use at Eielson AFB.

After discovering the PFAS contamination in Moose Creek residents’ private wells, the Air Force immediately began providing bottled water to affected well owners, and then implemented other mitigation efforts. This includes installing granular activated carbon (GAC) fltration on many homes in the Moose Creek community who consented to have them installed. Some homes have water delivered. In 2019 the Air Force released a plan for providing a piped water system from the City of North Pole to the Moose Creek community.

Sampling Area 

CDC/ATSDR identifed Moose Creek as an area with private wells that had PFAS levels above the EPA health advisory. All households served by private wells in this area will be invited to participate, even if their previous well testing results were below the health advisory and even if they have never tested their private wells. The exposure assessment will only consider households served by private wells.

Individuals in selected households will be eligible to participate if they:

  • Are 3 years of age or older (Children will be included in the exposure assessment only if we have consent from a parent or legal guardian.)
  • Do not have a bleeding disorder and are not anemic
  • Have lived in the sampling area for at least one year before December 28, 2017

CDC and ATSDR will begin an exposure assessment in Moose Creek in mid-July 2020. Recruitment will continue for four weeks, then we will be in Moose Creek for sampling in late August. Individual results will be mailed to participants. This could take several months. We will also write a final report summarizing the findings and recommendations for your community and present the results at an information session.
