New standard aims to detect ultrashort PFAS

ASTM International is drafting a new standard (WK88987) to measure ultrashort per- and polyfluoroalkyl substances (PFAS) – a group of highly persistent chemicals not currently addressed by existing methods.

PFAS are synthetic compounds valued for their resistance to heat, water, and oil, but they pose environmental and health risks. While established methods can detect short- and long-chain PFAS, no reference approach exists for ultrashort compounds with fewer than four carbon atoms.

The proposed method is being developed by ASTM’s subcommittee on organic substances in water (D19.06), part of the water committee (D19). Kesavalu Bagawandoss, ASTM member and General Manager at SGS North America Inc, highlighted the urgency: “We need reference methods for ultrashort PFAS in all matrices. This method would find immediate use as a standard for the world community once approved.”

A dedicated standard will improve global testing capabilities, enabling regulators, laboratories, and industry to better monitor PFAS contamination. It will also support efforts aligned with the UN Sustainable Development Goals for clean water and good health.

ASTM encourages experts and stakeholders to contribute to the development of this standard.
