PFAS in Lumes's tap water: 3 ng/L, 6x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
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 Lumes, the 4 most closely watched PFAS (PFAS-4) add up to 3 ng/L (0.003 µg/L) at the latest PFAS check on 21 July 2026. That's 6 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 4 ng/L (0.004 µg/L), below the EU legal limit (100 ng/L). 4 checks since 14 March 2025: sum of 20 PFAS up to 4 ng/L, sometimes below the detection limit.

Details and sources
PFAS over time in Lumes
4 PFAS checks since 14 March 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Lumes. Samples come from 2 distribution networks. The trend refers to the network “LUMES”.
“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 | Network |
|---|---|---|---|---|
| 3 ng/L – < 5 ng/L · calculated | 4 ng/L | Lumes | LUMES | |
| 2 ng/L – < 5 ng/L · calculated | 4 ng/L | Nouvion-sur-Meuse | NOUVION SUR MEUSE ET COMMUNES RACCORDÉES | |
| < 4 ng/L · calculated | < 100 ng/L | Lumes | LUMES | |
| < 4 ng/L · calculated | < 100 ng/L | Nouvion-sur-Meuse | NOUVION SUR MEUSE ET COMMUNES RACCORDÉES |
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 Lumes safe to drink?
All the values shown here (21 July 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “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 Lumes's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 4 ng/L. The EU limit is 100 ng/L, so this water is at 4 % of the limit. (below the EU limit)
Does the water in Lumes 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 3 ng/L stays below.
Are PFAS levels rising in Lumes'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 Lumes?
The water hardness in Lumes is 29.1 °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.
Same water network
Same distribution network as Lumes, so in principle the same water.
