PFAS in Palau-de-Cerdagne's tap water: under 24 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 24 ng/L, 48 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.
Sample taken in Osséja, on the same distribution network as Palau-de-Cerdagne (OSSEJA - PALAU DE CERDAGNE). The health authority samples one tap per network; a network carries the same treated water everywhere.
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 2 to 10 ng/L upward. None reached that limit, so their total is below 24 ng/L rather than zero.

Frequently asked questions
Is tap water in Palau-de-Cerdagne safe to drink?
At the latest check, the water was over at least one limit. “Eau d'alimentation non conforme aux exigences de qualité en vigueur. L a non-conformité concerne au moins un paramètre microbiologique et n'a pas nécessité de restriction de la consommation de l'eau. Il a été de mandé à l'exploitant de prendre les mesures correctives nécessaires po ur rétablir la qualité de l'eau. Un nouveau contrôle a été programmé a fin de suivre l'évolution du paramètre et de vérifier le retour à une situation normale.”
How high are PFAS levels in Palau-de-Cerdagne's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 2 ng/L. The EU limit is 100 ng/L, so this water is under 2 % of the limit. (below the EU limit)
Does the water in Palau-de-Cerdagne also meet the strictest limits in Europe?
The check cannot say. None of the four compounds was quantified, but the laboratory's detection limits add up to 24 ng/L, above Sweden's legal limit of 4 ng/L in force since 2026, so a value between the two would go unnoticed.
How hard is the water in Palau-de-Cerdagne?
The water hardness in Palau-de-Cerdagne is 4 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
