PFAS in Nilvange's tap water: under 8 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 8 ng/L, 16 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 Hayange, on the same distribution network as Nilvange (FONTOY 1). 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 2 ng/L upward. None reached that limit, so their total is below 8 ng/L rather than zero.

None found. The lab sees nothing below 8 ng/L, so our 0.5 ng/L benchmark cannot be checked.

In Nilvange, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 30 May 2025. The total is below 8 ng/L, the sum of the detection limits and 16 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <0,005 µg/L, below the EU legal limit (100 ng/L). Sampled in Hayange, on the same network. 2 checks since 1 April 2025: sum of 20 PFAS up to 13 ng/L, sometimes below the detection limit.

PFAS over time in Nilvange
2 PFAS checks since 1 April 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 |
|---|---|---|---|
| < 8 ng/L · calculated | < 5 ng/L | Hayange | |
| < 8 ng/L · calculated | 13 ng/L | Hayange |
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 Nilvange safe to drink?
Yes. At the check on 24 July 2026, the tap water in Nilvange was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”
How high are PFAS levels in Nilvange's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 5 ng/L. The EU limit is 100 ng/L, so this water is under 5 % of the limit. (below the EU limit)
Does the water in Nilvange 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 8 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 Nilvange'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 Nilvange?
No hardness value is available for Nilvange in this source.
Where does this data come from?
