Drinking water quality in Lillebonne
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 February 2026)
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 authorities have not published an overall verdict for this water.
„Eau d'alimentation non conforme aux exigences de qualité fixées pour la chloridazone desphényl et la chloridazone méthyl desphényl. Les concentrations mesurées dans le cadre du contrôle renforcé sont inférieures aux valeurs sanitaires maximales respectives de 11 µg/l et de 110 µg/l définies par les autorités, y compris en cas de présence simultanée. La collectivité bénéficie d'une dérogation préfectorale pendant la réalisation des études et travaux nécessaires au retour à la conformité. L'eau peut être consommée sans risque pour la santé.“

Frequently asked questions
Is tap water in Lillebonne safe to drink?
All the values shown here (2 June 2026) are within the legal limits, but the authorities have not published an overall verdict for this water.
How high are PFAS levels in Lillebonne's 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. (below the EU limit)
Does the water in Lillebonne also meet the strictest limits in Europe?
Yes. Even against Europe's strictest limit, the health limit of 0.004 µg/L used in Sweden since 2026, the measured value of 0 µg/L stays below.
How hard is the water in Lillebonne?
The water hardness in Lillebonne is 24.7 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
