PFAS in Rocroi's tap water: 6 ng/L, 12x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
12× 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 Rocroi, the 4 most closely watched PFAS (PFAS-4) add up to 6 ng/L (0.006 µg/L) at the latest PFAS check on 7 August 2025. That's 12 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 10 ng/L (0.01 µg/L), below the EU legal limit (100 ng/L).

Frequently asked questions
Is tap water in Rocroi safe to drink?
Yes. At the check on 20 April 2026, the tap water in Rocroi was within every limit tested. “Eau d'alimentation conforme aux limites et aux références de qualité. La teneur en chlore est toutefois largement supérieure aux valeurs préconisées dans la réglementation (0,1 à 0,3 mg/L). Cette teneur devra par conséquent être ramenée à une valeur plus conforme à celles préconisées par la réglementation.”
How high are PFAS levels in Rocroi's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 10 ng/L. The EU limit is 100 ng/L, so this water is at 10 % of the limit. (below the EU limit)
Does the water in Rocroi also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 6 ng/L. That is 1.5 times Sweden's legal limit of 4 ng/L, in force since 2026. Germany will set a similar one in 2028. The water still passes the current EU legal limit (100 ng/L for the total of 20 PFAS).
How hard is the water in Rocroi?
The water hardness in Rocroi is 23.4 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
