Forever Chemicals found in bottled and tap water from around the world

A recent study conducted by researchers from the University of Birmingham and other institutions has revealed the presence of per- and polyfluoroalkyl substances (PFAS), commonly known as "Forever Chemicals," in drinking water worldwide. The study found these toxic chemicals in both bottled and tap water from major cities in the UK and China, with over 99% of bottled water samples from 15 countries containing PFAS, particularly perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). Notably, tap water in Shenzhen, China, exhibited higher PFAS concentrations compared to Birmingham, UK. While the levels of PFAS in most samples were below health advisory limits, average PFOS concentrations in Shenzhen exceeded the newly established maximum contaminant level by the US Environmental Protection Agency. The researchers emphasized the effectiveness of simple treatment methods, such as boiling water or using filtration jugs, which can reduce PFAS levels by 50% to 90%. They also highlighted the need for ongoing monitoring and regulation to safeguard public health, as PFAS are linked to various adverse health effects. The study underscores the importance of consumer awareness regarding PFAS in drinking water and suggests that socio-economic factors may influence exposure levels.

- PFAS, or "Forever Chemicals," were found in drinking water globally, including bottled and tap water.

- Over 99% of bottled water samples contained PFAS, with higher concentrations in Shenzhen, China, compared to Birmingham, UK.

- Simple treatment methods can significantly reduce PFAS levels in drinking water.

- Most PFAS levels were below health advisory limits, but some samples exceeded new contaminant levels set by the EPA.

- Ongoing monitoring and regulation are essential to protect public health from PFAS exposure.
