PFAS in Somme-Tourbe's tap water: under 4 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
None of the 4 most harmful 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 Somme-Tourbe safe to drink?
At the latest check, the water was over at least one limit. “L'eau distribuée présente des concentrations en pesticides supérieures aux exigences réglementaires fixées à 0,1 µg/l, mais inférieures aux valeurs définies pour en limiter les usages sanitaires. Un contrôle renforcé est en place et des actions sont engagées par l’exploitant pour restaurer la qualité de l’eau. Cette eau est de bonne qualité pour les autres paramètres. Elle peut être consommée par tous.”
How high are PFAS levels in Somme-Tourbe'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 Somme-Tourbe 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 Somme-Tourbe?
The water hardness in Somme-Tourbe is 21.1 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
