Environmental Restoration (ER) Program Area 

The objective of this Statement on Need (SON) was to develop an improved understanding of the ecological toxicity and risk associated with per- and polyfluoroalkyl substances (PFAS) in avian species at or near Aqueous Film-Forming Foam (AFFF)-impacted sites. Specifically, the goal was to address the following research needs:

  • Improve the understanding of the uptake and excretion rates of PFAS by avian species to include assessment of correlation between effects reported in the scientific literature in laboratory exposures and observed population effects in the field.
  • Develop and/or validate modeling tools that can define exposures in comparison to established avian toxicity reference values (TRVs).
  • Assess PFAS bioaccumulation and biomagnification throughout a food web with avian species as the receptor.
  • Determine whether observed PFAS mixtures in avian tissue, serum, or eggs are correlated with any adverse population level effects.

The projects listed below were selected to address the objectives of this SON. Additional information on individual projects can be found by clicking the project title.

Research should lead to a better understanding of the environmental impact of AFFF-impacted sites and direct impact on the DoD’s ability to manage these sites more cost effectively while being protective of human health and the environment.
