ABSTRACT

There is increasing concern of Per- and Polyfluoroalkyl Substances (PFAS) in our soil, and environment as a whole, due to their persistent nature. More and more regulation regarding PFAS is being implemented. Having a harmonized method to accurately determine the PFAS content in soil as well as other matrices is important to this industry. The extraction of PFAS can be challenging given the susceptibly to contamination and the low levels in which these compounds are present. Existing techniques do not offer a method that is rapid, simple, and efficient. In this study, a new extraction system, the EDGE, combines the processes of pressurized fluid extraction and dispersive solid phase extraction is explored. This new method offers efficient extraction of PFAS from soil in less than 10 minutes in one simple process. The EDGE method offers a rapid, simple, and efficient solution for PFAS testing.
