PFAS in Chavanat's tap water: under 44 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 44 ng/L, 88 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 La Nouaille, on the same distribution network as Chavanat (ST SULPICE LES CHAMPS VALLIERE). 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 1 to 40 ng/L upward. None reached that limit, so their total is below 44 ng/L rather than zero.

None found. The lab sees nothing below 44 ng/L, so our 0.5 ng/L benchmark cannot be checked.

Frequently asked questions
Is tap water in Chavanat safe to drink?
Yes. At the check on 22 June 2026, the tap water in Chavanat was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité définies par le Code de la Santé Publique, pour les paramètres mesurés au moment du prélèvement.”
How high are PFAS levels in Chavanat'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 Chavanat 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 44 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 Chavanat?
The water hardness in Chavanat is 10.4 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
