PFAS - "Forever chemicals" in drinking water

It’s one of the biggest environmental scandals ever to hit Germany. In 2012, a routine inspection uncovers industrial chemicals, known as PFAS, in the drinking water of the southern German town of Rastatt. PFAS, perfluorinated and polyfluorinated alkyl compounds, are found in many everyday products such as Teflon pans and water-repellent clothing. They accumulate in the environment and in tissue and can cause considerable damage. PFAS pose risks to human health including an increased risk of certain cancers, fertility issues and a reduced response to vaccinations. PFAS are highly persistent in the environment and don’t readily break down, which is why they’re also known as "forever chemicals". The EU is currently considering a PFAS ban.
