PFAS in the tap water of Santenay (Côte-d'Or): 2.31 ng/L, 4.6x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
4.6× above our health benchmark
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.
Substances below the detection limit count as 0, so the real total may be higher.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

In Santenay, the 4 most closely watched PFAS (PFAS-4) add up to 2.31 ng/L (0.0023 µg/L) at the latest PFAS check on 12 May 2026. That's 4.6 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 2.96 ng/L (0.003 µg/L), below the EU legal limit (100 ng/L). 2 checks since 2 December 2025: PFAS-4 from 0.74 ng/L to 2.31 ng/L.

Frequently asked questions
Is tap water in Santenay safe to drink?
At the latest check, the water was over at least one limit. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”
How high are PFAS levels in Santenay's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 2.96 ng/L. The EU limit is 100 ng/L, so this water is at 3 % of the limit. (below the EU limit)
Does the water in Santenay also meet the strictest limits in Europe?
Yes. Even against Europe's strictest legal limit, Sweden's 4 ng/L in force since 2026, the measured value of 2.31 ng/L stays below.
Are PFAS levels rising in Santenay's tap water?
Too few quantified checks to say (2 since 2 December 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values.
How hard is the water in Santenay?
The water hardness in Santenay is 41 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 21 September 2026.
