PFAS in the tap water of Buxerolles (Côte-d'Or): under 2.5 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 2.5 ng/L, 5 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 Chambain, on the same distribution network as Buxerolles (SIAEP DE CHAMBAIN BUXEROLLES). 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 0.5 to 1 ng/L upward. None reached that limit, so their total is below 2.5 ng/L rather than zero.

Frequently asked questions
Is tap water in Buxerolles safe to drink?
Yes. At the check on 20 July 2026, the tap water in Buxerolles was within every limit tested. “Eau d'alimentation conforme aux normes en vigueur pour l'ensemble des paramètres mesurés.”
How high are PFAS levels in Buxerolles's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 6.25 ng/L. The EU limit is 100 ng/L, so this water is at 6 % of the limit. (below the EU limit)
Does the water in Buxerolles 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 2.5 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 Buxerolles?
The water hardness in Buxerolles is 23.9 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
