PFAS in Visoncourt's tap water: 4 ng/L, 8x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
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 Breuches, on the same distribution network as Visoncourt (SIAEP DE BREUCHES). 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 Visoncourt, the 4 most closely watched PFAS (PFAS-4) add up to 4 ng/L (0.004 µg/L) at the latest PFAS check on 6 July 2026. That's 8 times our 0.5 ng/L health benchmark, exactly at Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 92 ng/L (0.092 µg/L), below the EU legal limit (100 ng/L). Sampled in Breuches, on the same network. 4 checks since 18 August 2025: PFAS-4 from 3 ng/L to 22 ng/L, averaging 11 ng/L over 12 months. Falling on the main network.

PFAS over time in Visoncourt
5 PFAS checks since 17 March 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Visoncourt.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.
