PFAS in drinking water

70× above our health benchmark

Amount found in the water 35 ng/L 0.035 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 Bernis, the 4 most closely watched PFAS (PFAS-4) add up to 35 ng/L (0.035 µg/L) at the latest PFAS check on 23 June 2026. That's 70 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 65 ng/L (0.065 µg/L), below the EU legal limit (100 ng/L). 5 checks since 7 August 2025: sum of 20 PFAS up to 65 ng/L, sometimes below the detection limit.

PFAS over time in Bernis

5 PFAS checks since 7 August 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Bernis.

“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 Bernis safe to drink?

Yes. At the check on 30 July 2026, the tap water in Bernis was within every limit tested. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité.”

How high are PFAS levels in Bernis's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 65 ng/L. The EU limit is 100 ng/L, so this water is at 65 % of the limit. (below the EU limit)

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

No. The four most harmful PFAS add up to 35 ng/L. That is 8.8 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 Bernis'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 Bernis?

The water hardness in Bernis is 35.2 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?
