PFAS in Montigny-en-Morvan's tap water: under 4 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
None of the 4 most harmful 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 Montigny-en-Morvan safe to drink?
Yes. At the check on 24 November 2025, the tap water in Montigny-en-Morvan was within every limit tested. Outside a reference value: Electrical conductivity 89 µS/cm on 24 November 2025 (reference 200–1,100 µS/cm), Iron 362 µg/L on 24 November 2025 (reference ≤ 200 µg/L). These are indicator parameters with reference values, not legal limits. “Les résultats ont mis en évidence un dépassement de la référence de qu alité définie pour l'aluminium (2 593 microgrammes/L pour une référenc e de qualité fixée à 200 microgrammes/L) et pour le fer (362 microgrammes/L pour une référence de qualité fixée à 200 microgrammes/ L) . Il convient d’en rechercher l’origine et de mettre en oeuvre les mesures correctives, notamment en adaptant les paramètre s de la station de traitement. Un prélèvement de recontrôle est programmé pour ces paramètres. La teneur en chlore est insuffisante pour garantir une désinfection ef ficace de l’eau distribuée sur l’ensemble du réseau. Il est recommandé de maintenir au moins 0,1 mg/L en tout point du réseau. Les autres paramètres mesurés répondent aux normes de potabilité, excepté la cond uctivité”
How high are PFAS levels in Montigny-en-Morvan's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 3 ng/L. The EU limit is 100 ng/L, so this water is at 3 % of the limit. (below the EU limit)
Does the water in Montigny-en-Morvan 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 Montigny-en-Morvan?
The water hardness in Montigny-en-Morvan is 1.4 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
