PFAS in the tap water of Dommartin (Nièvre): 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.
Sample taken in Montigny-en-Morvan, on the same distribution network as Dommartin (LAC). 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 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 Dommartin safe to drink?
Yes. At the check on 4 March 2026, the tap water in Dommartin was within every limit tested. Outside a reference value: Electrical conductivity 59 µS/cm on 4 March 2026 (reference 200–1,100 µS/cm), Turbidity 5.8 NFU on 4 March 2026 (reference ≤ 2 NFU). These are indicator parameters with reference values, not legal limits. “Les résultats ont mis en évidence la non conformité suivante : Eau non conforme à la référence de qualité définie pour la turbidité : 5,8 NFU pour une référence à 2 NFU. Teneur en chlore : Chlore libre < 0,03 mg/L. Les résultats bactériologiques sont conforme s. Il convient de maintenir une chloration suffisante afin de prévenir to ut problème bactériologique ; de suivre le paramètre turbidité et d'aj uster le traitement si nécessaire. Les autres paramètres mesurés répondent aux normes de potabilité, exce pté la conductivité.”
How high are PFAS levels in Dommartin'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 Dommartin 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 Dommartin?
The water hardness in Dommartin is 1.9 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
