Bottled Beverages and PFAS: An Understudied Exposure
While regulatory attention focuses on tap water PFAS, commercially produced beverages—sports drinks, juices, flavored waters, and soft drinks—are manufactured using water that may contain PFAS. These products represent a daily PFAS exposure pathway for consumers who believe they are avoiding tap water contamination by purchasing packaged beverages.
Manufacturing Water as a PFAS Source
Beverage manufacturers use local municipal or well water in product formulation. Facilities in PFAS-affected regions may produce beverages with PFAS from the manufacturing water source. Unlike bottled water, which FDA regulates with standards aligned to EPA tap water requirements, other beverages—sports drinks, juices, soft drinks—do not face specific PFAS content standards.
Consumer Testing Results
Independent testing of commercially available beverages has detected PFAS in some products, including sports drinks and flavored waters, at concentrations ranging from below detection to several ng/L. Brands manufactured at facilities using PFAS-contaminated source water or processing equipment with PFAS-containing components show the highest contamination levels in testing programs.
Regulatory Coverage Gaps
FDA regulates bottled water PFAS standards (as tap water standards apply to bottled water under SDWA) but lacks equivalent standards for non-water beverages containing PFAS. This regulatory gap means consumers seeking to minimize PFAS exposure through beverage choices lack the information needed to compare PFAS content across product categories. Advocacy for FDA beverage PFAS testing and disclosure requirements is advancing in response to these exposure data gaps
