PFAS in the tap water of Chevannes (Côte-d'Or): under 2.5 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
None of the 4 most harmful PFAS detected
The lab sees nothing below 2.5 ng/L, 5 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 ng/L upward. None reached that limit, so their total is below 2.5 ng/L rather than zero.

In Chevannes, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 20 July 2026. The total is below 2.5 ng/L, the sum of the detection limits and 5 times our 0.5 ng/L benchmark. Sum of 20 PFAS: 26.11 ng/L (0.0261 µg/L), below the EU legal limit (100 ng/L). 2 checks since 8 April 2025: sum of 20 PFAS up to 26.11 ng/L, sometimes below the detection limit.

PFAS over time in Chevannes
2 PFAS checks since 8 April 2025, from the published measurements.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.
| Date | PFAS-4 | Sum of 20 PFAS |
|---|---|---|
| < detection limit | 26.11 ng/L | |
| < 2.5 ng/L · calculated | < detection limit |
Calculated values: “<” is an upper bound from published thresholds, “≥” a lower bound, “–” means no published sum or complete measurement. How to read a PFAS result
What the latest check found
At the latest check, the water was within every limit tested.
Values to watch
These results are close to their legal limit, or over it.
Outside a reference value: Coliform bacteria 2 n/(100mL) on 20 July 2026 (reference ≤ 0 mL)). These are indicator parameters with reference values, not legal limits.

Frequently asked questions
Is tap water in Chevannes safe to drink?
Yes. At the check on 20 July 2026, the tap water in Chevannes was within every limit tested. Outside a reference value: Coliform bacteria 2 n/(100mL) on 20 July 2026 (reference ≤ 0 mL)). These are indicator parameters with reference values, not legal limits. “Référence de qualité non satisfaite (indicateur de qualité) pour les paramètres : Bactéries coliformes et Spores de micro-organismes sulfitoréducteurs. Surveiller la désinfection.”
How high are PFAS levels in Chevannes's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 26.11 ng/L. The EU limit is 100 ng/L, so this water is at 26 % of the limit. (below the EU limit)
Does the water in Chevannes 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 2.5 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 Chevannes'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.
How hard is the water in Chevannes?
The water hardness in Chevannes is 34.6 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
