Your Favorite Sparkling Water May Contain ‘Forever Chemicals'
You might think of sparkling water as a healthy choice, but a 2020 Consumer Reports study revealed alarming levels of PFAS (Per- and Polyfluoroalkyl Substances) in popular brands.
PFAS are also known as “forever chemicals” because they don’t degrade in the environment — or in the human body. These compounds have been linked to a range of health issues.
The PFAS levels in a bottle of water are thought to be determined by its source and its exposure to PFAS-containing substances, rather than the carbonation process itself.
According to the report, Topo Chico, owned by Coca-Cola, contained the highest levels of PFAS at 9.76 ppt (parts per trillion), followed by Polar (6.41 ppt) and Bubly (2.24 ppt).
In contrast, Sparkling Ice is PFAS-free. Schweppes, Dasani, San Pellegrino, and Spindrift contain less than 1 ppt, while Poland Spring, Canada Dry, and Perrier place in the middle.
Despite the dangers posed by PFAS, there are grounds for optimism as efforts in research and legislation aim to help consumers once again enjoy safe, clean sparkling water.
