PFAS in Tavant's tap water: under 3 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 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 Sazilly, on the same distribution network as Tavant (SAZILLY-TAVANT). 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.

Frequently asked questions
Is tap water in Tavant safe to drink?
All the values shown here (28 July 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité pour la température. Une température élevée de l’eau stimule la croissance des micro-organismes et peut accroître les problèmes liés au goût, à l’odeur, à la coloration et à la corrosion. Ce contrôle fait suite aux résultats d'analyses du prélèvement du 27/07/2026 qui présentaient une concentration en Ammonium non conforme, en application de l'article R.1321-17 du code de la santé publique.”
How high are PFAS levels in Tavant'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 Tavant 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.
How hard is the water in Tavant?
The water hardness in Tavant is 21.1 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
