PFAS in Amathay-Vésigneux'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.
Sample taken in Lods, on the same distribution network as Amathay-Vésigneux (SIEPA AMATHAY-VESIGNEUX). 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.

In Amathay-Vésigneux, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 27 October 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: 1 ng/L (0.001 µg/L), below the EU legal limit (100 ng/L). Sampled in Lods, on the same network. 2 checks since 25 June 2025, PFAS-4 always below the detection limit (4 ng/L). Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

PFAS over time in Amathay-Vésigneux
3 PFAS checks since 18 February 2025, from the published measurements.
“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 | Sampled at |
|---|---|---|---|
| < 4 ng/L | 1 ng/L | Lods | |
| < 20 ng/L | < 28 ng/L | Lods | |
| < 4 ng/L · calculated | < 100 ng/L | Lods |
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
What the latest check found
At the latest check, the water was within every limit tested.
Values to watch
These results are close to their legal limit, or over it.
Outside a reference value: Coliform bacteria 1 n/(100mL) on 21 July 2026 (reference ≤ 0 mL)), Turbidity 13 NFU on 21 July 2026 (reference ≤ 2 NFU). These are indicator parameters with reference values, not legal limits.
| What was tested | Value | Limit | Status |
|---|---|---|---|
| Lead | 52 µg/L | ≤ 10 µg/L | over the limit |
| Coliform bacteria | 1 n/(100mL) | ≤ 0 mL) | above the reference value |

Frequently asked questions
Is tap water in Amathay-Vésigneux safe to drink?
At the latest check, the water was over at least one limit. “EAU CONFORME MAIS NON SATISFAISANTE (code de la santé publique). L'eau prélevée contient des coliformes totaux indicateurs d'une conta mination microbiologique. Cette présence peut indiquer un dysfonctionn ement du dispositif de traitement ou peut être liée au point de prélèv ement. De plus l'eau prélevée ne respecte pas les exigences de qualité physico-chimique en raison de la turbidité, ce qui entraîne des désag réments pour les usagers et renforce le risque de contamination microb iologique. L’eau reste consommable.”
How high are PFAS levels in Amathay-Vésigneux's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 1 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 Amathay-Vésigneux 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 Amathay-Vésigneux's tap water?
Too few quantified checks to say (0 since 18 February 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values. These history statistics use laboratory-published sums only.
How hard is the water in Amathay-Vésigneux?
The water hardness in Amathay-Vésigneux is 27.1 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
