PFAS in Germondans's tap water: under 4 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
No PFAS detected
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.
Sample taken in Blarians, on the same distribution network as Germondans (SIE DE LA FONTAINE). 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.
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.

Frequently asked questions
Is tap water in Germondans safe to drink?
Yes. At the check on 13 April 2026, the tap water in Germondans was within every limit tested. Outside a reference value: Electrical conductivity 168 µS/cm on 15 December 2025 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “EAU CONFORME (code de la santé publique) L'eau prélevée respecte les limites de qualité réglementaires des eaux destinées à l'alimentation humaine pour les paramètres analysés. A noter cependant la faible conductivité de l'eau.”
How high are PFAS levels in Germondans's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 29 ng/L. The EU limit is 100 ng/L, so this water is under 29 % of the limit. (below the EU limit)
Does the water in Germondans 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 Germondans?
No hardness value is available for Germondans in this source.
Where does this data come from?
