PFAS in the tap water of Saint-Médard (Moselle): under 8 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 8 ng/L, 16 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 2 ng/L upward. None reached that limit, so their total is below 8 ng/L rather than zero.

At the latest check, the water was over at least one limit.
Values to watch
These results are close to their legal limit, or over it.
Outside a reference value: Electrical conductivity 1,300 µS/cm on 25 February 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits.

Frequently asked questions
Is tap water in Saint-Médard safe to drink?
At the latest check, the water was over at least one limit. “Eau d'alimentation non conforme à la limite de qualité réglementaire pour le paramètre nitrates. La consommation de l'eau est déconseillée aux femmes enceintes et aux nourrissons de moins de 6 mois. Les mesures correctives nécessaires doivent être prises afin de rétablir la qualité de l'eau. Un suivi analytique renforcé est réalisé pour vérifier l'évolution de ce paramètre.”
How high are PFAS levels in Saint-Médard's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 5 ng/L. The EU limit is 100 ng/L, so this water is under 5 % of the limit. (below the EU limit)
Does the water in Saint-Médard 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 8 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 Saint-Médard?
The water hardness in Saint-Médard is 81 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
