Drinking water quality in Nassandres sur Risle
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. (14 May 2025)
The four most harmful PFAS add up to 0 µg/L, below the health limit of 0.004 µg/L used in Sweden since 2026.
Substances too small to measure count as 0, so the real total may be higher.

Official assessment
The latest official test failed at least one quality requirement.
„Eau d'alimentation non conforme aux exigences de qualité fixées pour p lusieurs sous-produits de dégradation de pesticides (chloridazone des phényl, chloridazone méthyl desphényl, chlorothalonil R417888, chlorot halonil R471811). Toutefois, les concentrations mesurées sont inférieu res aux seuils sanitaires. En raison de la présence régulière de perchlorates à des concentration s supérieures à 4 µg/L, il est recommandé de ne pas utiliser cette eau pour la préparation des biberons des nourrissons de moins de 6 mois.“
