PFAS in Autheuil-Authouillet's tap water: 18 ng/L, 36x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
36× above our health benchmark
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 Cailly-sur-Eure, on the same distribution network as Autheuil-Authouillet (CAILLY). 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.
Substances below the detection limit count as 0, so the real total may be higher.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

Frequently asked questions
Is tap water in Autheuil-Authouillet safe to drink?
Yes. At the check on 9 July 2026, the tap water in Autheuil-Authouillet was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés. Toutefois, la présence de bactéries aérobies revivifiables en quantité importante est observée.”
How high are PFAS levels in Autheuil-Authouillet's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 20 ng/L. The EU limit is 100 ng/L, so this water is at 20 % of the limit. (below the EU limit)
Does the water in Autheuil-Authouillet also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 18 ng/L. That is 4.5 times Sweden's legal limit of 4 ng/L, in force since 2026. Germany will set a similar one in 2028. The water still passes the current EU legal limit (100 ng/L for the total of 20 PFAS).
How hard is the water in Autheuil-Authouillet?
The water hardness in Autheuil-Authouillet is 27.9 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
