PFAS in La Croix-aux-Bois's tap water: under 4 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 4 ng/L, 8 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.
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 1 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

Frequently asked questions
Is tap water in La Croix-aux-Bois safe to drink?
Yes. At the check on 17 April 2026, the tap water in La Croix-aux-Bois was within every limit tested. Outside a reference value: Electrical conductivity 150 µS/cm on 17 April 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “La teneur en chlore est largement supérieure aux valeurs préconisées d ans 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.Le s résultats sont conformes aux limites de qualité (norme impérative) pour l'ensemble des paramètres analysés. Cependant les références de qualité (norme non impérative) relatives à la présence d e bactéries anaérobies sulfito-réductrices y compris les spores et de ge rmes ne sont pas satisfaites. Une vérification des installations peut s'avérer nécessaire. Sur le plan chimique, l'eau est agressive. L'efficacité du traitement devra être vérifiée ou un traitement de neutralisation devra être installé. La teneur en aluminium est supérieure à la référence de qualité.”
How high are PFAS levels in La Croix-aux-Bois's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 28 ng/L. The EU limit is 100 ng/L, so this water is under 28 % of the limit. (below the EU limit)
Does the water in La Croix-aux-Bois also meet the strictest limits in Europe?
As far as this check can tell, yes. None of the four compounds was quantified, so their total is below 4 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.
How hard is the water in La Croix-aux-Bois?
The water hardness in La Croix-aux-Bois is 5.2 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
