PFAS in Le Fidelaire's tap water: under 4 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
No PFAS detected
The lab sees nothing below 4 ng/L, 8 times our benchmark of 0.5 ng/L. Water above our benchmark would pass this check unnoticed.
0.5 ng/L is our benchmark, not an official limit. Same EFSA method as Sweden, Denmark and the Netherlands, but stricter. It's a yearly average, compared here with the latest check.
More about this result
The US also limits PFOA and PFOS to 4 ng/L each, per substance.
The lab detects each of the four substances from 1 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

Frequently asked questions
Is tap water in Le Fidelaire safe to drink?
All the values shown here (23 June 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “Eau d'alimentation conforme à la limite de qualité fixée pour le chlorure de vinyle. La présence de cette substance dans l'eau s'explique par sa migration à partir de certaines canalisations d'eau potable en PVC antérieur à 1980 dans des conditions bien particulières. Une contamination a été identifiée sur le tronçon de canalisation desservant les habitations situées au hameau de Frémontel. Des actions destinées à assurer la conformité de l'eau distribuée sont en cours sur ce secteur.”
How high are PFAS levels in Le Fidelaire's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at –. The EU limit is 100 ng/L, so this water is at – of the limit. (below the EU limit)
Does the water in Le Fidelaire also meet the strictest limits in Europe?
As far as this check can tell, yes. None of the four compounds was quantified, so their total is below 4 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.
How hard is the water in Le Fidelaire?
The water hardness in Le Fidelaire is 29.3 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
