The German Federation for the Environment and Nature Conservation (BUND) has detected problematic PFAS chemicals in Berlin’s ground- and drinking water. According to BUND, four out of five samples exceeded current limit values.
Per- and polyfluorinated alkyl substances (PFAS) are a group of substances, known as ‘forever chemicals’. PFAS comprise more than 10,000 artificially produced compounds that are virtually impossible to break down in nature due to their stable carbon-fluorine bonds.
PFAS are widespread globally. Scientists at Stockholm University have demonstrated that rainwater worldwide, including in Antarctica and the Tibetan Highlands, is contaminated with PFAS. PFAS are also detectable in the blood of nearly all people worldwide.
According to numerous studies, the chemicals reduce the activity of immune cells, leading to higher susceptibility to infection. The substances are also said to cause cancer, infertility and contribute to obesity. The chemicals find widespread use in everyday life due to their fat and water-repellent properties. They are found in outdoor clothing, waterproofing sprays, coated pans and food packaging, particularly for fatty foods like burgers, chips, pizza and sandwiches.
From 12 January 2026, a new limit for drinking water will apply in Germany: the sum of 20 selected PFAS compounds may not exceed 100 nanograms per litre. At EU level, a comprehensive ban has been under discussion since February 2023. A decision is expected at the end of 2026.
BUND is calling for restrictions on PFAS distribution to stop the “increasing pollution of our environment.” The organisation also argues that those responsible should bear the costs of consequences, such as treating drinking water.
