PFAS in the tap water of Pierrefiche (Aveyron): under 6 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 6 ng/L, 12 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 La Capelle-Bonance, on the same distribution network as Pierrefiche (VALLEES DE LA SERRE ET D'OLT). 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 1.5 ng/L upward. None reached that limit, so their total is below 6 ng/L rather than zero.

Frequently asked questions
Is tap water in Pierrefiche safe to drink?
Yes. At the check on 20 July 2026, the tap water in Pierrefiche was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”
How high are PFAS levels in Pierrefiche'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 Pierrefiche 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 6 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 Pierrefiche?
No hardness value is available for Pierrefiche in this source.
Where does this data come from?
