PFAS in Tox's tap water: under 8 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 8 ng/L, 16 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 2 ng/L upward. None reached that limit, so their total is below 8 ng/L rather than zero.

In Tox, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 21 January 2026. The total is below 8 ng/L, the sum of the detection limits and 16 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,005 µg/L, below the EU legal limit (100 ng/L).

Frequently asked questions
Is tap water in Tox safe to drink?
At the latest check, the water was over at least one limit. “Eau d'alimentation non-conforme aux exigences de qualité. Présence de germes témoins de contamination fécale. La teneur en chlore libre est insuffisante. Turbidité hors norme.”
How high are PFAS levels in Tox's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 5 ng/L. The EU limit is 100 ng/L, so this water is under 5 % of the limit. (below the EU limit)
Does the water in Tox also meet the strictest limits in Europe?
The check cannot say. None of the four compounds was quantified, but the laboratory's detection limits add up to 8 ng/L, above Sweden's legal limit of 4 ng/L in force since 2026, so a value between the two would go unnoticed.
How hard is the water in Tox?
The water hardness in Tox is 10.7 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
