PFAS in Doudeville's tap water: 7.4 ng/L, 14.8x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
14.8× 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 Berville-en-Caux, on the same distribution network as Doudeville (ST PIERRE DE BENOUVILLE). 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).

In Doudeville, the 4 most closely watched PFAS (PFAS-4) add up to 7.4 ng/L (0.0074 µg/L) at the latest PFAS check on 23 January 2026. That's 14.8 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 17.9 ng/L (0.0179 µg/L), below the EU legal limit (100 ng/L). Sampled in Berville-en-Caux, on the same network. 4 checks since 10 February 2025: sum of 20 PFAS up to 17.9 ng/L, sometimes below the detection limit.

Details and sources
PFAS over time in Doudeville
4 PFAS checks since 10 February 2025, from the published measurements. Samples from 3 communes on the same network: it's the same water, so each one applies to Doudeville. Samples come from 2 distribution networks. The trend refers to the network “ST PIERRE DE BENOUVILLE”.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Frequently asked questions
Is tap water in Doudeville safe to drink?
All the values shown here (23 June 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “Eau d'alimentation conforme, le jour du prélèvement, aux exigences de qualité pour l'ensemble des paramètres mesurés. Nota Bene : Les teneurs ne valent que pour le point d'utilisation où elles ont été mesurées. Compte tenu de l'influence du réseau de distribution d'eau (réseau intérieur et éventuellement branchement public) sur la dissolution des métaux, ces valeurs ne sont pas représentatives de la qualité de l'eau pour l'ensemble des consommateurs du réseau de distribution.”
How high are PFAS levels in Doudeville's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 17.9 ng/L. The EU limit is 100 ng/L, so this water is at 18 % of the limit. (below the EU limit)
Does the water in Doudeville also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 7.4 ng/L. That is 1.85 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).
Are PFAS levels rising in Doudeville's tap water?
Calculated PFAS-4 values are listed in the table. The chart uses laboratory-published sum-of-20 results; there are too few laboratory-published PFAS-4 sums for the existing trend calculation.
How hard is the water in Doudeville?
No hardness value is available for Doudeville in this source.
