Drinking water quality in Château-Renault
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at <SEUIL µg/L. The EU limit is 0.1 µg/L, so this water is at 0 % of the limit. (10 June 2025)
This source does not list each PFAS substance separately, so we cannot compare this water with the health limit.

Official assessment
The latest official test passed all quality requirements.
„Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité pour la température. Une température élevée de l’eau stimule la croissance des micro-organismes et peut accroître les problèmes liés au goût, à l’odeur, à la coloration et à la corrosion.“
