Austria’s Groundwater PFAS Contamination Expands Amid New EU Limits

Per‑ and polyfluoroalkyl substances (PFAS) have been detected in groundwater near Mannswörth, Lower Austria, after decades of firefighting foam use at the OMV refinery site in Schwechat. Experts say the soil acts as a long‑term source, slowly leaching PFAS into wells, irrigation and potentially drinking water.

Helmut Burtscher‑Schaden of Global 2000 warned that “Bei AFFF‑Löschschäumen ist das Erdreich oft die eigentliche Langzeitquelle.” The contamination is likely more widespread than previously thought, with elevated levels already found in regions such as South Styria, the Mur River corridor and near Salzburg Airport.

The EU will enforce a strict drinking‑water limit of 0.1 µg/L for twenty PFAS compounds from 12 January 2026, and the European Chemicals Agency has recommended a broad ban on these “eternal chemicals.” Austrian fire services stopped using PFAS foams for training in October 2025, though portable extinguishers containing PFAS may remain on the market until 2030. Health agencies highlight the carcinogenic potential of substances like PFOA and PFOS, underscoring the urgency of remediation.
