A jurisdiction adopts a hard PFAS limit in drinking water (typically aligned with the EU Drinking Water Directive 0.1 µg/L sum-of-20 ceiling), and regional water utilities face a dated cliff: install GAC / ion-exchange / RO polishing on every contaminated wellhead, or take wells off-line and buy more expensive bulk replacement water. The pattern shows up in different jurisdictions with country-specific deadlines, fines and vendor ecosystems — but operators face the same underlying squeeze. Filter by country or industry above.
