PFAS in Le Thoronet's tap water: under 4 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
None of the 4 most harmful 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.

In Le Thoronet, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 7 May 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: 2 ng/L (0.002 µg/L), below the EU legal limit (100 ng/L). 3 checks since 3 February 2025: sum of 20 PFAS from 2 ng/L to 4 ng/L.

PFAS over time in Le Thoronet
3 PFAS checks since 3 February 2025, from the published measurements. Samples come from 3 distribution networks. The trend refers to the network “ADDUC. LE THORONET VIDAL”.
“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 Le Thoronet safe to drink?
Yes. At the check on 10 July 2026, the tap water in Le Thoronet was within every limit tested. Outside a reference value: Electrical conductivity 1,262 µS/cm on 10 July 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Eau conforme aux limites de qualité fixées par le Code de la Santé Publique concernant les eaux destinées à la consommation humaine pour les paramètres recherchés. A noter le dépassement de la référence de qualité pour le paramètre conductivité. Une vigilance particulière doit être accordée à la surveillance de la corrosion du réseau.”
How high are PFAS levels in Le Thoronet's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 2 ng/L. The EU limit is 100 ng/L, so this water is at 2 % of the limit. (below the EU limit)
Does the water in Le Thoronet 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 Le Thoronet'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 Le Thoronet?
The water hardness in Le Thoronet is 38.5 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
