PFAS in Chauvigny'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.

In Chauvigny, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 24 July 2026. The total is below 4 ng/L, the sum of the detection limits and 8 times our 0.5 ng/L benchmark. Sum of 20 PFAS: <SEUIL µg/L, below the EU legal limit (100 ng/L). 6 checks since 22 April 2026, PFAS-4 always below the detection limit (4 ng/L).

Frequently asked questions
Is tap water in Chauvigny safe to drink?
Yes. At the check on 28 July 2026, the tap water in Chauvigny 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 Chauvigny's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at –. The EU limit is 100 ng/L, so this water is at – of the limit. (below the EU limit)
Does the water in Chauvigny 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 Chauvigny's tap water?
No. Since 4 April 2025, 6 checks have been published and the PFAS-4 sum stayed below the laboratory's detection limit (4 ng/L) every time. These history statistics use laboratory-published sums only.
How hard is the water in Chauvigny?
The water hardness in Chauvigny is 30 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
