Lynn L. Bergeson, “PFAS: making sound investment decisions,” Financier Worldwide, March 2022.

The ubiquity of per- and polyfluoroalkyl substances (PFAS) and the manufacturing sector’s decades-long reliance on them to impart functionalities in a dizzying array of products put the investor between the proverbial rock and a hard place. PFAS varied chemical properties make the broad categorisation of ‘PFAS’ into a monolithic category of ‘forever chemicals’ chemically and scientifically questionable.

For better or worse, however, that is exactly what is happening today, and distinguishing between commercially promising and commercially risky PFAS chemicals is challenging. Yet, the ability to make this distinction could be the difference between a great investment and a commercially disastrous one. This article explores this difficult assessment, provides essential information on PFAS, and offers some suggestions to avoid making bad investment decisions.
