PFAS in Cravant-les-Côteaux'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.
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 Cravant-les-Côteaux safe to drink?
All the values shown here (8 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 et l'ammonium. 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 01/07/2026 qui présentaient une concentration en Ammonium non conforme, en application de l'article R.1321-17 du code de la santé publique et confirme la situation. Il est nécessaire de surveiller cet état de fait, afin d’y remédier dans les plus brefs délais.”
How high are PFAS levels in Cravant-les-Côteaux'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 Cravant-les-Côteaux 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 Cravant-les-Côteaux's tap water?
Calculated PFAS-4 values are listed in the table. The chart uses laboratory-published sum-of-20 results; there are too few laboratory-published PFAS-4 sums for the existing trend calculation.
