PFAS in drinking water

No PFAS detected

Amount found in the water < 4 ng/L the 4 most harmful PFAS (PFAS-4) · the lab's detection limit 20 PFAS looked for, none found
Our health benchmark 0.5 ng/L

The lab sees nothing below 4 ng/L, 8 times our benchmark of 0.5 ng/L. Water above our benchmark would pass this check unnoticed.

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.

The lab detects each of the four substances from 1 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

None found. The lab sees nothing below 4 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Brusson, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 2 April 2025. The total is below 4 ng/L, the sum of the detection limits and 8 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,100 µg/L, below the EU legal limit (100 ng/L).

Frequently asked questions

Is tap water in Brusson safe to drink?

All the values shown here (10 July 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”

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

At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 100 ng/L. The EU limit is 100 ng/L, so this water is under 100 % of the limit. (below the EU limit)

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

As far as this check can tell, yes. None of the four compounds was quantified, so their total is below 4 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.

How hard is the water in Brusson?

The water hardness in Brusson is 32.2 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?

All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 21 September 2026.
