Lately, per- and polyfluoroalkyl substances (PFAS) have been on the minds of many water professionals and an active subject matter for legislators. The water industry’s heightened interest in PFAS was triggered by many factors, including sampling data from the third Unregulated Contaminant Monitoring Rule (UCMR 3). According to the US Environmental Protection Agency (USEPA), UCMR 3 showed substantial PFAS occurrence in US water supplies. To cover all the intricacies of PFAS, AWWA’s Organic Contaminant Controls and Organic Contaminants Research committees are planning to organize a PFAS symposium in the coming year, either in person or virtually. In the meantime, this column answers some common questions about PFAS in drinking water.
