PFAS in Ville-le-Marclet'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 Ville-le-Marclet, the 4 most closely watched PFAS (PFAS-4) add up to 4 ng/L (0.004 µg/L) at the latest PFAS check on 14 January 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: 28 ng/L (0.028 µg/L), below the EU legal limit (100 ng/L). 2 checks since 28 February 2025: sum of 20 PFAS from 26 ng/L to 28 ng/L.

Frequently asked questions
Is tap water in Ville-le-Marclet safe to drink?
Yes. At the check on 20 July 2026, the tap water in Ville-le-Marclet 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 Ville-le-Marclet's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 28 ng/L. The EU limit is 100 ng/L, so this water is at 28 % of the limit. (below the EU limit)
Does the water in Ville-le-Marclet 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.
Are PFAS levels rising in Ville-le-Marclet'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 Ville-le-Marclet?
The water hardness in Ville-le-Marclet is 20.6 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
