PFAS in Buxières-d'Aillac's tap water: under 3 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 3 ng/L, 6 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 Velles, on the same distribution network as Buxières-d'Aillac (VELLES ARTHON). 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 1.5 ng/L upward. None reached that limit, so their total is below 3 ng/L rather than zero.

In Buxières-d'Aillac, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 17 November 2025. The total is below 3 ng/L, the sum of the detection limits and 6 times our 0.5 ng/L benchmark. Sum of 20 PFAS: 5 ng/L (0.005 µg/L), below the EU legal limit (100 ng/L). Sampled in Velles, on the same network. 2 checks since 31 May 2024: sum of 20 PFAS up to 5 ng/L, sometimes below the detection limit.

Frequently asked questions
Is tap water in Buxières-d'Aillac safe to drink?
Yes. At the check on 17 November 2025, the tap water in Buxières-d'Aillac was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”
How high are PFAS levels in Buxières-d'Aillac's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 5 ng/L. The EU limit is 100 ng/L, so this water is at 5 % of the limit. (below the EU limit)
Does the water in Buxières-d'Aillac 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 3 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.
Are PFAS levels rising in Buxières-d'Aillac's tap water?
