In 2012, a routine inspection in the southern German town of Rastatt turns up industrial PFAS compounds in the local drinking water, and this DW film follows how the discovery unravels into one of Germany's largest environmental scandals. Olaf Kaspryk, head of Rastatt's public works department, leads the search for the contamination's source, tracing it back to compost spread on farmland. Farmers destroy entire harvests, residents stop drinking tap water only to learn the chemicals are already in their blood, and mothers are warned against breastfeeding. Interviews with officials and affected residents lay out the human cost while the film explains what PFAS actually are: compounds used in Teflon pans and water-repellent clothing that barely break down once released, earning the nickname "forever chemicals." The remediation and investigation bill has reached 40 million euros, and the EU's push toward a PFAS ban runs through the film as a policy response still catching up to the damage already done in one town's water supply and soil.
