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.
