PFAS in Magnat-l'Étrange's tap water: under 13 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 13 ng/L, 26 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 Poussanges, on the same distribution network as Magnat-l'Étrange (POUSSANGES). 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 1.5 to 5 ng/L upward. None reached that limit, so their total is below 13 ng/L rather than zero.

In Magnat-l'Étrange, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 30 March 2026. The total is below 13 ng/L, the sum of the detection limits and 26 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <SEUIL µg/L, below the EU legal limit (100 ng/L). Sampled in Poussanges, on the same network. 3 checks since 3 September 2025, sum of 20 PFAS always below the detection limit.

PFAS over time in Magnat-l'Étrange
3 PFAS checks since 3 September 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Magnat-l'Étrange.
“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 |
|---|---|---|---|
| < 13 ng/L · calculated | < detection limit | Poussanges | |
| < 6 ng/L · calculated | < detection limit | Poussanges | |
| < 6 ng/L · calculated | < detection limit | Magnat-l'Étrange |
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 Magnat-l'Étrange safe to drink?
Yes. At the check on 30 March 2026, the tap water in Magnat-l'Étrange was within every limit tested. Outside a reference value: Electrical conductivity 140 µS/cm on 5 February 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Eau d'alimentation conforme aux exigences de qualité définies par le Code de la Santé Publique, pour les paramètres mesurés au moment du prélèvement, à l’exception du paramètre conductivité. Une optimisation du traitement de neutralisation est nécessaire.”
How high are PFAS levels in Magnat-l'Étrange's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at –. The EU limit is 100 ng/L, so this water is at – of the limit. (below the EU limit)
Does the water in Magnat-l'Étrange 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 13 ng/L, above Sweden's legal limit of 4 ng/L in force since 2026, so a value between the two would go unnoticed.
Are PFAS levels rising in Magnat-l'Étrange'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 Magnat-l'Étrange?
The water hardness in Magnat-l'Étrange is 5.5 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
