PFAS in drinking water

86× above our health benchmark

Amount found in the water 43 ng/L 0.043 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.

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 Barbey, the 4 most closely watched PFAS (PFAS-4) add up to 43 ng/L (0.043 µg/L) at the latest PFAS check on 12 February 2026. That's 86 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 55 ng/L (0.055 µg/L), below the EU legal limit (100 ng/L). 2 checks since 20 August 2025: sum of 20 PFAS from 55 ng/L to 72 ng/L.

Frequently asked questions

Is tap water in Barbey safe to drink?

Yes. At the check on 9 July 2026, the tap water in Barbey 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 Barbey's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 55 ng/L. The EU limit is 100 ng/L, so this water is at 55 % of the limit. (below the EU limit)

Does the water in Barbey also meet the strictest limits in Europe?

No. The four most harmful PFAS add up to 43 ng/L. That is 10.7 times Sweden's legal limit of 4 ng/L, in force since 2026. Germany will set a similar one in 2028. The water still passes the current EU legal limit (100 ng/L for the total of 20 PFAS).

Are PFAS levels rising in Barbey'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 Barbey?

The water hardness in Barbey is 26 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?
