PFAS in Saulieu's tap water: under 2.5 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 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.
Sample taken in Saint-Martin-de-la-Mer, on the same distribution network as Saulieu (SESAM, R. SAULIEU). 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 ng/L upward. None reached that limit, so their total is below 2.5 ng/L rather than zero.

In Saulieu, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 20 April 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: <SEUIL µg/L, below the EU legal limit (100 ng/L). Sampled in Saint-Martin-de-la-Mer, on the same network. 2 checks since 1 September 2025, PFAS-4 always below the detection limit.

PFAS over time in Saulieu
5 PFAS checks since 24 March 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Saulieu.
“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 | Sampled at |
|---|---|---|---|
| < detection limit | < detection limit | Saint-Martin-de-la-Mer | |
| < detection limit | < detection limit | Saint-Martin-de-la-Mer | |
| < 2.5 ng/L · calculated | < detection limit | Champeau-en-Morvan | |
| < 2.5 ng/L · calculated | < detection limit | Saint-Martin-de-la-Mer | |
| < 2.5 ng/L · calculated | 0.55 ng/L | Saint-Martin-de-la-Mer |
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

Frequently asked questions
Is tap water in Saulieu safe to drink?
Yes. At the check on 28 July 2026, the tap water in Saulieu was within every limit tested. Outside a reference value: Electrical conductivity 196 µS/cm on 28 July 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “La conductivité n'est pas conforme à la référence de qualité nécessitant une optimisation du traitement et une adaptation à la qualité de l'eau brute. À noter que la teneur en COT a atteint la valeur de la référence de qualité pour ce paramètre.”
How high are PFAS levels in Saulieu'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 Saulieu 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 Saulieu's tap water?
Too few quantified checks to say (0 since 24 March 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values. These history statistics use laboratory-published sums only.
How hard is the water in Saulieu?
The water hardness in Saulieu is 6.6 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
