PFAS in La Ferrière-Airoux's tap water: 1.5 ng/L, 3x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
3× 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 Magné, on the same distribution network as La Ferrière-Airoux (GENCAY LA PRELE-PUY RABIER). 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 La Ferrière-Airoux, the 4 most closely watched PFAS (PFAS-4) add up to 1.5 ng/L (0.0015 µg/L) at the latest PFAS check on 20 May 2025. That's 3 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 3 ng/L (0.003 µg/L), below the EU legal limit (100 ng/L). Sampled in Magné, on the same network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).
