PFAS in Vaudherland's tap water: 4 ng/L, 8x our 0.5 ng/L benchmark

PFAS in drinking water

8× above our health benchmark

Amount found in the water 4 ng/L 0.004 µg/L · the 4 most harmful PFAS (PFAS-4)
Our health benchmark 0.5 ng/L

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 Le Thillay, on the same distribution network as Vaudherland (LE THILLAY - VAUDHERLAND). 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 Vaudherland, the 4 most closely watched PFAS (PFAS-4) add up to 4 ng/L (0.004 µg/L) at the latest PFAS check on 21 October 2025. 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: 14 ng/L (0.014 µg/L), below the EU legal limit (100 ng/L). Sampled in Le Thillay, on the same network. 3 checks since 20 March 2025: sum of 20 PFAS up to 21 ng/L, sometimes below the detection limit.

Frequently asked questions

Is tap water in Vaudherland safe to drink?

Yes. At the check on 21 October 2025, the tap water in Vaudherland 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 Vaudherland's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 14 ng/L. The EU limit is 100 ng/L, so this water is at 14 % of the limit. (below the EU limit)

Does the water in Vaudherland 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 4 ng/L stays below.

Are PFAS levels rising in Vaudherland'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 Vaudherland?

No hardness value is available for Vaudherland in this source.

Where does this data come from?
