PFAS in Saint-Épain's tap water: under 10 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 10 ng/L, 20 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 to 4 ng/L upward. None reached that limit, so their total is below 10 ng/L rather than zero.

Frequently asked questions
Is tap water in Saint-Épain safe to drink?
Yes. At the check on 16 July 2026, the tap water in Saint-Épain was within every limit tested. Outside a reference value: Electrical conductivity 1,405 µS/cm on 16 July 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité pour le paramètre conductivité (mesure la quantité de minéraux dissous de l'eau). Cette situation a pour origine la nature de la ressource exploitée (nappe du cénomanien) et ne présente pas un danger pour la santé des consommateurs.”
How high are PFAS levels in Saint-Épain'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 Saint-Épain 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 10 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-Épain?
The water hardness in Saint-Épain is 27.9 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
