PFAS in Feins-en-Gâtinais's tap water: under 4 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 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 Escrignelles, on the same distribution network as Feins-en-Gâtinais (ESCRIGNELLES-FEINS). 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 Feins-en-Gâtinais safe to drink?
At the latest check, the water was over at least one limit. “Ce prélèvement a mis en évidence une concentration en OXA Alachlore non conforme à la limites de qualité réglementaires de 0,1µg/l ainsi que des dépassements de la valeur indicative de 0,9 µg/L sur des métabolites de pesticides non pertinent, ce qui nécessitent que vous preniez des mesures correctives afin de rétablir la qualité de l'eau et m'en informiez ainsi que les consommateurs (art. R.1321-27 à 30 du code de la santé publique). Ces non- conformité ne nécessite cependant pas de restriction de consommation de l’eau. Un suivi renforcé est mis en place sur ces paramètres. Les autres paramètres mesurés sont conformes aux exigences de qualité.”
How high are PFAS levels in Feins-en-Gâtinais's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 1 ng/L. The EU limit is 100 ng/L, so this water is under 1 % of the limit. (below the EU limit)
Does the water in Feins-en-Gâtinais 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.
