A recent BBC study on tap water found that the levels of PFAS, or “forever chemicals,” exceeded European safety levels in over half of the samples taken. PFAS are man-made chemicals that are designed to never break down in the environment. They’re commonly used in non-stick cookware, clothing, furniture, carpets, and many other products.

Currently, UK guidelines allow up to 100 nanograms per liter (ng/l) of PFAS in tap water. However, the European Union allows only 2.2 ng/l. Out of the 45 samples taken by the BBC, 25 had PFAS. None exceeded the UK guidelines, but almost half exceeded the EU guidelines. Professor Roger Klein, a British expert on PFAS, said that the UK guidelines were ridiculous.

PFAS have been linked to a number of illnesses such as cancer and even high cholesterol, and some experts say that there’s actually no safe level for PFAS in drinking water. Many scientists believe that everyone in the world now has PFAS in their blood. “This stuff is everywhere,” Professor Klein explained.
