PFAS in Sorigny's tap water: 0.8 ng/L, 1.6x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
1.6× above our health benchmark
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.
Substances below the detection limit count as 0, so the real total may be higher.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

In Sorigny, the 4 most closely watched PFAS (PFAS-4) add up to 0.8 ng/L (0.0008 µg/L) at the latest PFAS check on 5 May 2026. That's 1.6 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 1.4 ng/L (0.0014 µg/L), below the EU legal limit (100 ng/L). 4 checks since 15 May 2025: sum of 20 PFAS up to 1.4 ng/L, sometimes below the detection limit.

Details and sources
PFAS over time in Sorigny
4 PFAS checks since 15 May 2025, from the published measurements. Samples come from 2 distribution networks. The trend refers to the network “SORIGNY”.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.
| Date | PFAS-4 | Sum of 20 PFAS | Network |
|---|---|---|---|
| 0.8 ng/L – < 3.3 ng/L · calculated | 1.4 ng/L | SORIGNY | |
| < 3 ng/L · calculated | 1.2 ng/L | ISOPARC | |
| < 3 ng/L · calculated | 1.2 ng/L | ISOPARC | |
| < 10 ng/L · calculated | < detection limit | SORIGNY |
Calculated values: “<” is an upper bound from published thresholds, “≥” a lower bound, “–” means no published sum or complete measurement. How to read a PFAS result

Frequently asked questions
Is tap water in Sorigny safe to drink?
Yes. At the check on 7 July 2026, the tap water in Sorigny was within every limit tested. Outside a reference value: Electrical conductivity 1,224 µS/cm on 7 July 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité pour la température et la conductivité (nappe du cénomanien). Une température élevée de l’eau stimule la croissance des micro-organismes et peut accroître les problèmes liés au goût, à l’odeur, à la coloration et à la corrosion. Ce contrôle fait suite aux résultats d'analyses du prélèvement du 01/07/2026 qui présentaient une valeur des micro-rganismes revivifiables à 22 et 36°C anormalement élevée, en application del'article R.1321-17 du code de la santé publique.”
How high are PFAS levels in Sorigny's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 1.4 ng/L. The EU limit is 100 ng/L, so this water is at 1 % of the limit. (below the EU limit)
Does the water in Sorigny also meet the strictest limits in Europe?
Yes. Even against Europe's strictest legal limit, Sweden's 4 ng/L in force since 2026, the measured value of 0.8 ng/L stays below.
Are PFAS levels rising in Sorigny'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 Sorigny?
The water hardness in Sorigny is 28.2 °f (medium). 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.
