PFAS in Sélestat's tap water: 7 ng/L, 14x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
14× 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).

Frequently asked questions
Is tap water in Sélestat safe to drink?
Yes. At the check on 31 July 2026, the tap water in Sélestat was within every limit tested. “Eau destinée à la consommation humaine conforme aux limites et aux références de qualité réglementaires pour les paramètres analysés.”
How high are PFAS levels in Sélestat's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 9 ng/L. The EU limit is 100 ng/L, so this water is at 9 % of the limit. (below the EU limit)
Does the water in Sélestat also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 7 ng/L. That is 1.75 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 Sélestat?
The water hardness in Sélestat is 26.7 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
