PFAS in Wolfersdorf's tap water: under 8 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
No PFAS detected
The lab sees nothing below 8 ng/L, 16 times our benchmark of 0.5 ng/L. Water above our benchmark would pass this check unnoticed.
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.
Sample taken in Traubach-le-Haut, on the same distribution network as Wolfersdorf (S.D.E. TRAUBACH LE HAUT ET ENV). The health authority samples one tap per network; a network carries the same treated water everywhere.
More about this result
The US also limits PFOA and PFOS to 4 ng/L each, per substance.
The lab detects each of the four substances from 2 ng/L upward. None reached that limit, so their total is below 8 ng/L rather than zero.

None found. The lab sees nothing below 8 ng/L, so our 0.5 ng/L benchmark cannot be checked.

Values to watch
These results are close to their legal limit, or over it.
One routine sample was outside a limit: Lead 45 µg/L on 24 April 2023 (limit ≤ 10 µg/L), Copper 2.37 mg(Cu)/L on 24 April 2023 (limit ≤ 2 mg(Cu)/L), Nickel 143 µg/L on 24 April 2023 (limit ≤ 20 µg/L). This is a single result, not an official verdict on the supply. Outside a reference value: Electrical conductivity 130 µS/cm on 16 March 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits.

Frequently asked questions
Is tap water in Wolfersdorf safe to drink?
Yes. At the check on 16 March 2026, the tap water in Wolfersdorf was within every limit tested. One routine sample was outside a limit: Lead 45 µg/L on 24 April 2023 (limit ≤ 10 µg/L), Copper 2.37 mg(Cu)/L on 24 April 2023 (limit ≤ 2 mg(Cu)/L), Nickel 143 µg/L on 24 April 2023 (limit ≤ 20 µg/L). This is a single result, not an official verdict on the supply. Outside a reference value: Electrical conductivity 130 µS/cm on 16 March 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité. Eau douce, agressive, très faiblement minéralisée susceptible, dans certaines conditions défavorables (notamment stagnation de l'eau), de dissoudre certains métaux des canalisations. Il est conseillé de ne consommer l'eau du robinet qu'après un écoulement de 15 à 30 secondes. L'absence de canalisation en plomb dans les parties privatives des réseaux doit être vérifiée.”
How high are PFAS levels in Wolfersdorf's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 5 ng/L. The EU limit is 100 ng/L, so this water is under 5 % of the limit. (below the EU limit)
Does the water in Wolfersdorf also meet the strictest limits in Europe?
The check cannot say. None of the four compounds was quantified, but the laboratory's detection limits add up to 8 ng/L, above Sweden's legal limit of 4 ng/L in force since 2026, so a value between the two would go unnoticed.
How hard is the water in Wolfersdorf?
The water hardness in Wolfersdorf is 4.3 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
