PFAS in Port-de-Bouc's tap water: 1 ng/L, 2x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
2× 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 Port-de-Bouc, the 4 most closely watched PFAS (PFAS-4) add up to 1 ng/L (0.001 µg/L) at the latest PFAS check on 5 March 2026. That's 2 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 12 ng/L (0.012 µg/L), below the EU legal limit (100 ng/L). 11 checks since 11 February 2025: sum of 20 PFAS from 3 ng/L to 24 ng/L.

Frequently asked questions
Is tap water in Port-de-Bouc safe to drink?
Yes. At the check on 2 July 2026, the tap water in Port-de-Bouc was within every limit tested. “L’eau d’alimentation est conforme aux limites de qualité et non conforme aux références de qualité pour le paramètre température.”
How high are PFAS levels in Port-de-Bouc's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 12 ng/L. The EU limit is 100 ng/L, so this water is at 12 % of the limit. (below the EU limit)
Does the water in Port-de-Bouc 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 1 ng/L stays below.
Are PFAS levels rising in Port-de-Bouc'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 Port-de-Bouc?
The water hardness in Port-de-Bouc is 23.2 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
