Drinking water quality in Luneray
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at 0.0026 µg/L. The EU limit is 0.1 µg/L, so this water is at 3 % of the limit. (3 February 2026)
The four most harmful PFAS add up to 0.0013 µg/L, below the health limit of 0.004 µg/L used in Sweden since 2026.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).
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 plusieurs sous-produits de dégradation de pesticides. Les concentrations mesurées dans le cadre du contrôle renforcé sont inférieures aux valeurs sanitaires 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 Luneray safe to drink?
All the values shown here (3 February 2026) are within the legal limits, but the authorities have not published an overall verdict for this water.
How high are PFAS levels in Luneray's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.0026 µg/L. The EU limit is 0.1 µg/L, so this water is at 3 % of the limit. (below the EU limit)
Does the water in Luneray 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 0.0013 µg/L stays below.
How hard is the water in Luneray?
The water hardness in Luneray is 26.1 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
