The PFAS conundrum: Mass spectrometry solutions for addressing it.

The increasing interest regarding the occurrence of Per-and Polyfluoroalkyl Substances(PFAS) in the environment since the general public become aware of the results from the Unregulated Contaminant Monitoring Rule3 and the quantitation of GenX in drinking water has resulted in an acceleration of activities by stakeholders in volved in addressing this issue. Multiple Federal and State Agencies (e.g.EPA,DOD,DEQsandDEPs) in the United States as well as international organizations(e.g.ASTM) are quickly publishing new analytical methodologies for PFAS monitoring and establishing more stringent limits. However, these rapid changes in monitoring requirements pose a challenge for environmental laboratories.
