PFAS in Thénorgues'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.
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 Thénorgues, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 21 July 2026. 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: <0,029 µg/L, below the EU legal limit (100 ng/L). 22 checks since 17 February 2025: sum of 20 PFAS up to 328 ng/L, sometimes below the detection limit.

Frequently asked questions
Is tap water in Thénorgues safe to drink?
The authorities have not published an overall verdict for this water. Outside a reference value: Coliform bacteria 1 n/(100mL) on 21 July 2026 (reference ≤ 0 mL)). These are indicator parameters with reference values, not legal limits. “Les trois paramètres analysés sont conformes aux exigences de qualité mais ne sont représentatifs que du point d'utilisation et du moment où ils ont été mesurés. Ce résultat ne prouve pas que le réseau de distribution (réseau intérieur et/ou branchement public) ne comporte pas d'éléments (canalisations, soudures…) contenant du plomb. Ces valeurs ne sont pas représentatives de la qualité de l'eau pour l'ensemble des consommateurs du réseau de distribution.”
How high are PFAS levels in Thénorgues'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 Thénorgues 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.
Are PFAS levels rising in Thénorgues'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 Thénorgues?
The water hardness in Thénorgues is 30.8 °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.
