PFAS in Lisbourg's tap water: 4 ng/L, 8x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
8× 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 Lisbourg, the 4 most closely watched PFAS (PFAS-4) add up to 4 ng/L (0.004 µg/L) at the latest PFAS check on 13 March 2026. That's 8 times our 0.5 ng/L health benchmark, exactly at Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 14 ng/L (0.014 µg/L), below the EU legal limit (100 ng/L).

Frequently asked questions
Is tap water in Lisbourg safe to drink?
Yes. At the check on 17 July 2026, the tap water in Lisbourg 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 Lisbourg's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 14 ng/L. The EU limit is 100 ng/L, so this water is at 14 % of the limit. (below the EU limit)
Does the water in Lisbourg 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 4 ng/L stays below.
