PFAS in Bréville-les-Monts's tap water: 3.7 ng/L, 7.4x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
7.4× 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 Bavent, on the same distribution network as Bréville-les-Monts (RESEAU HAUT RDO). 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).
More PFAS than in 90% of the cities we track

In Bréville-les-Monts, the 4 most closely watched PFAS (PFAS-4) add up to 3.7 ng/L (0.0037 µg/L) at the latest PFAS check on 3 June 2026. That's 7.4 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 6.5 ng/L (0.0065 µg/L), below the EU legal limit (100 ng/L). Sampled in Bavent, on the same network. 6 checks since 4 March 2025: sum of 20 PFAS up to 6.8 ng/L, sometimes below the detection limit.

Details and sources
PFAS over time in Bréville-les-Monts
6 PFAS checks since 4 March 2025, from the published measurements. Samples from 3 communes on the same network: it's the same water, so each one applies to Bréville-les-Monts. Samples come from 2 distribution networks. The trend refers to the network “ZONE COTIERE”.
“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 Bréville-les-Monts safe to drink?
Yes. At the check on 3 June 2026, the tap water in Bréville-les-Monts 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 Bréville-les-Monts's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 6.5 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 Bréville-les-Monts 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 3.7 ng/L stays below.
Are PFAS levels rising in Bréville-les-Monts'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 Bréville-les-Monts?
The water hardness in Bréville-les-Monts is 43.1 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
