Are you sticking with drinking Bottled Water? Assessment of PFAS content in commercial samples

The presence of Per- and Polyfluorinated Alkyl Substances (PFAS) in drinking water is being thoroughly studied due to the persistence of these compounds in the environment and their potential health effects. However, there is limited knowledge about the occurrence of these chemicals in bottled water, despite the increasing concerns about PFAS in the food supply. This poster shows results from a fast and simple direct injection method similar to EPA method 8237, using the Shimadzu LCMS-8050 to analyze seven commercially available samples of bottled water for 24 PFAS. The results demonstrate that the instrument’s performance exceeds the requirements in FDA draft method C-010.01 for other matrices, including milk (which is the most similar to water), as well as the limits established by the EPA for drinking water. While the origin of the water itself maybe the source of PFAS in bottled water, we also wanted to investigate the importance of the type of materials. Migration of PFAS from Food Contact Materials (FCM) is known to occur in all kinds of food containers. In this study, we procured bottled water in several different bottle materials, as well as two types of water source. These included spring and purified water, and bottles made from 5 different kinds of container materials: plastic (virgin and recycled), glass, metal, and cardboard. Preliminary results indicate that observed PFAS levels seem to depend on both the bottle material and the water source.
