Drinking water quality in Foucherans
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at 0.082 µg/L. The EU limit is 0.1 µg/L, so this water is at 82 % of the limit. (31 March 2026)
The four most harmful PFAS add up to 0.045 µg/L. That is 11.3 times the health limit of 0.004 µg/L that Sweden made law in 2026. Germany will set a similar limit in 2028.
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 latest official test passed all quality requirements.
„Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés. Une surveillance anticipée de certains paramètres émergents, dont les per- et polyfluoroalkylées (PFAS), a été mise en place par l’ARS. Les résultats de ce suivi ont montré des valeurs supérieures à la limite d e qualité fixée à 0,1 µg/l pour la somme des PFAS. Les collectivités o nt engagé, en lien avec l’ARS et la préfecture, un plan d’action pour rétablir la qualité de l’eau. Les modalités de gestion sont basées sur l’application du principe de proportionnalité au regard des connaissa nces et expertises du moment et ne conduisent pas, à ce stade, à prono ncer des restrictions d’usages de l’eau. Pour plus d’informations sur les PFAS, vous pouvez consulter le site internet de l’ARS :https://www .bourgogne-franche-comte.ars.sante.fr/les-pfas-en-bourgogne-franche-co mte“

Frequently asked questions
Is tap water in Foucherans safe to drink?
Yes. The latest official test (13 April 2026) checked the tap water in Foucherans and it passed every requirement.
How high are PFAS levels in Foucherans's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.082 µg/L. The EU limit is 0.1 µg/L, so this water is at 82 % of the limit. (below the EU limit)
Does the water in Foucherans also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 0.045 µg/L. That is 11.3 times the health limit of 0.004 µg/L that Sweden made law in 2026. The water still passes the current EU limit (0.1 µg/L for the total of 20 PFAS).
How hard is the water in Foucherans?
The water hardness in Foucherans is 32.1 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
