Overview

• Générations Futures and Data For Good unveiled the monthly updated 'Dans Mon Eau' map showing pesticides, PFAS, nitrates, CVM and perchlorates at commune and address level using official ARS data.
• The report finds about 87% of distribution units compliant, yet 709 UDI networks (roughly 3%) could merit recommendations to limit consumption, with non‑conformities concentrated in the north and the Paris Basin.
• PFAS surveillance remains incomplete, with analyses missing in 52.4% of distribution units and some substances such as TFA not covered, prompting a petition for stronger monitoring and source protection.
• In the Vosges, Arrentès‑de‑Corcieux recorded PFAS far above recommended limits, with residents notified on October 14 following pressure from a local association, highlighting communication gaps.
• Local crises persist in the Ardennes where 13 communes covering roughly 3,000 people cannot drink tap water after extreme PFAS readings in July; authorities suspended sludge spreading on catchments, and utilities are testing filtration or network interconnections that could take months or longer to restore safe supply.
