Bottled water, often perceived as purer than tap water, hides a disturbing secret. After the massive detection of microplastics, a study published in the scientific journal ACS ES&T Water reveals massive contamination with “PFAS”, also called “eternal pollutants” in bottled waters around the world.
PFAS, these substances that never disappear
PFAS represent a family of synthetic chemical compounds widely used in industry. Their popularity is explained by their remarkable properties: they repel water and stains. But this efficiency hides a worrying flip side. These molecules practically do not degrade in the environment, hence their nickname “eternal pollutants”.
Alarming results on a global scale
Researchers analyzed samples from 87 bottled water brands in 15 different countries. To establish a basis for comparison, they also studied 55 samples of tap water in the United Kingdom and China. The verdict is final: Almost all bottled water contains PFAS, including those labeled as “natural.”
Long-term health risks
Prolonged exposure to PFAS raises serious health concerns. These substances accumulate in the body over time. Scientists have established links between these pollutants and various pathologies, prompting health authorities to increase their vigilance.
This study confronts the bottled water industry with its responsibilities. Several technical solutions are emerging to remove PFAS from water, but they only address symptoms of a deeper problem. Widespread contamination calls for a global and coordinated response.
Towards stricter regulation
Discovery of PFAS in bottled water strengthens calls for stricter regulations. Scientists are calling for better control of these substances, from their production to their final use.
The massive presence of eternal pollutants in bottled water upsets our certainties about the safety of our daily consumption. It’s hard to say which water is better for health and for our environment from now on…
- Study finds 99% of bottled water contains perennial pollutants (PFAS)
- These chemical substances, used for their waterproofing properties, hardly degrade in the environment2
- The discovery calls for stricter regulation and increased monitoring of these chemical compounds
