PFAS in drinking water

EU legal limit
<SEUIL µg/L Limit: 0.1 µg/L within limit

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. (19 February 2025)

Health limit (used in Sweden)
0 µg/L the 4 most harmful PFAS (PFAS-4) · Limit: 0.004 µg/L below health limit

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.

14 PFAS (see each substance)
Acide perfluoroheptane sulfonique (PFHpS) <0,004 µg/L
Acide perfluorododécanoique (PFDoDA) <0,002 µg/L
Acide perfluoro tridecane sulfonique (PFTrDS) <0,004 µg/L
Acide perfluorononane sulfonique (PFNS) <0,002 µg/L
Acide perfluoro-nonanoïque (PFNA) <0,002 µg/L
Acide perfluoropentanoïque (PFPEA) <0,010 µg/L
Acide perfluorobutanoïque (PFBA) <0,020 µg/L
Acide perfluoroheptanoïque (PFHPA) <0,002 µg/L
Acide sulfonique de perfluorobutane (PFBS) <0,010 µg/L
Acide perfluoro undecanoïque (PFUnA) <0,002 µg/L
Acide perfluorodecane sulfonique (PFDS) <0,002 µg/L

Water report for Mont-près-Chambord

Official assessment

The latest official test passed all quality requirements.

„En ce point de prélèvement, l'eau présente une teneur en plomb non conforme à la limite de qualité fixée à 10 µg/l. La teneur en plomb ne vaut que pour le point d'utilisation où elle a été mesurée. Compte tenu de l'influence du réseau de distribution d'eau (réseau intérieur et éventuellement branchement public) sur la dissolution des métaux, ces valeurs ne sont pas représentatives de la qualité de l'eau pour l'ensemble des consommateurs du réseau de distribution . Une restriction d'usage pour les femmes enceintes et les enfants de moins de 7 ans , dans le secteur concerné, a été demandée par la communauté de Grand Chambord, en charge de la producti on de l'eau potable. Des investigations sont en cours ainsi que des travaux de renouvelleme nt de matériel (robinet, clapet anti-retou,etc.).“
