PFAS in Mont-Cauvaire's tap water: under 5 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 5 ng/L, 10 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 to 2 ng/L upward. None reached that limit, so their total is below 5 ng/L rather than zero.

Frequently asked questions
Is tap water in Mont-Cauvaire safe to drink?
All the values shown here (2 July 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “Eau d'alimentation conforme, le jour du prélèvement, aux exigences de qualité pour l'ensemble des paramètres mesurés. Nota Bene : Les teneurs ne valent que pour le point d'utilisation où elles ont été mesurées. 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.”
How high are PFAS levels in Mont-Cauvaire'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 Mont-Cauvaire 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 5 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 Mont-Cauvaire?
The water hardness in Mont-Cauvaire is 14.2 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
