PFAS testing is entering a new phase. With seven ultrashort-chain organofluorine compounds included in EPA Method 563, drinking water laboratories face a new set of analytical challenges, from poor chromatographic retention and background contamination to limited fragmentation.

New EPA Method 563: Taking on the challenge of ultrashort-chain PFAS
PFAS testing is entering a new phase. With seven ultrashort-chain organofluorine compounds included in EPA Method 563, drinking water laboratories face a new set of analytical challenges, from poor chromatographic retention and background contamination to limited fragmentation.
Understanding PFAS and its impact on U.S. drinking water
In recent years, per- and polyfluoroalkyl substances (PFAS), often referred to as “forever chemicals,” have become a growing topic of interest due to their persistence in the environment and potential health risks. These synthetic compounds have been widely used in various industrial applications and consumer products since the 1940s. PFAS can be found in the air, soil, and water, and studies have shown that most people have detectable levels of PFAS in their bloodstream. One of the main exposure pathways for humans is through drinking water, particularly in communities located near industrial sites, military bases, or areas where firefighting foam has been used.
