Drinking water quality in Plonévez-du-Faou
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at 0.1413 µg/L. The EU limit is 0.1 µg/L, so this water is at 141 % of the limit. (16 June 2026)
The four most harmful PFAS add up to 0.0033 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 latest official test failed at least one quality requirement.
„Eau d'alimentation non-conforme aux limites de qualité : la somme des 20 PFAS est mesurée à 0,1413 µg/L, pour une limite de qualité fixée à 0,10 µg/L. Ce dépassement est principalement lié à la présence de PFBA, mesuré à 0,138 µg/L. Ce résultat constitue un signal dont la représentativité et la persistance doivent être caractérisées. Des analyses de recontrôle et des investigations complémentaires sont engagées. Dans l’attente de leurs résultats, aucune restriction des usages de l’eau n’est préconisée.“
