PFAS in Besse-et-Saint-Anastaise'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 Besse-et-Saint-Anastaise safe to drink?
At the latest check, the water was over at least one limit. “Eau d'alimentation non-conforme aux exigences de qualité.”
How high are PFAS levels in Besse-et-Saint-Anastaise's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 29 ng/L. The EU limit is 100 ng/L, so this water is under 29 % of the limit. (below the EU limit)
Does the water in Besse-et-Saint-Anastaise 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.
Are PFAS levels rising in Besse-et-Saint-Anastaise's tap water?
No. Since 23 May 2025, 9 checks have been published and the PFAS-4 sum stayed below the laboratory's detection limit (4 ng/L) every time.
How hard is the water in Besse-et-Saint-Anastaise?
The water hardness in Besse-et-Saint-Anastaise is 15.8 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
