PFAS in Biéville-Beuville's tap water: 3.2 ng/L, 6.4x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
6.4× 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 Blainville-sur-Orne, on the same distribution network as Biéville-Beuville (BLAINVILLE). 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 Biéville-Beuville, the 4 most closely watched PFAS (PFAS-4) add up to 3.2 ng/L (0.0032 µg/L) at the latest PFAS check on 20 July 2026. That's 6.4 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 5.9 ng/L (0.0059 µg/L), below the EU legal limit (100 ng/L). Sampled in Blainville-sur-Orne, on the same network. 13 checks since 21 January 2025: sum of 20 PFAS up to 16.6 ng/L, sometimes below the detection limit.

PFAS over time in Biéville-Beuville
13 PFAS checks since 21 January 2025, from the published measurements. Samples from 5 communes on the same network: it's the same water, so each one applies to Biéville-Beuville. Samples come from 4 distribution networks. The trend refers to the network “SAINT CONTEST”.
“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 Biéville-Beuville safe to drink?
Yes. At the check on 20 July 2026, the tap water in Biéville-Beuville 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 Biéville-Beuville's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 5.9 ng/L. The EU limit is 100 ng/L, so this water is at 6 % of the limit. (below the EU limit)
Does the water in Biéville-Beuville also meet the strictest limits in Europe?
Yes. Even against Europe's strictest legal limit, Sweden's 4 ng/L in force since 2026, the measured value of 3.2 ng/L stays below.
Are PFAS levels rising in Biéville-Beuville'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.
