Description:
The presence of per- and polyfluoroalkyl substances (PFAS) in the environment represents an
emerging issue due to their stability, bioaccumulation potential, and risks to human and ecological
well-being. There is a critical need to develop sampling methods for PFAS to assess risks and inform
remedial investigations and feasibility studies (RI/FS) at locations where historical releases have
elevated concentrations in soils and sediments. Passive sampling methods provide an indirect
approach for assessing risks associated with bioaccumulative compounds such as PFAS. There is a
need to develop standardized approaches for PFAS analysis in soils and sediments using passive
samplers. The technology could be used in the RI/FS process to evaluate various remedial
alternatives. Military bases are a major potential customer for the technology, as the Department of
Defense has estimated that legacy releases of PFAS represent a $2 billion liability. Landfills where
PFAS have been disposed of in the past are another potential customer. The market is estimated in
excess of $1 billion. Passive samplers provide a direct measure of potential bioaccumulation risks
unlike methods such as solvent extraction that are needed to minimize the costs associated with
environmental remediation because they measure the freely dissolved concentration that is available
for bioaccumulation.
