PFAS in Colombé-la-Fosse'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.
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.

Frequently asked questions
Is tap water in Colombé-la-Fosse safe to drink?
Yes. At the check on 10 July 2026, the tap water in Colombé-la-Fosse was within every limit tested. “Compte tenu des paramètres contrôlés, cette eau est conforme aux limites et références de qualité des eaux destinées à la consommation humaine, définies par l'arrêté du 11 janvier 2007, pour l'ensemble des paramètres mesurés. Il est à noter une teneur en chlore libre trop élevée. La teneur en chlore libre sur le réseau de distribution doit être de l'ordre de 0,1 mg/l.”
How high are PFAS levels in Colombé-la-Fosse'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 Colombé-la-Fosse 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 Colombé-la-Fosse?
The water hardness in Colombé-la-Fosse is 27.1 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
