PFAS in Baudoncourt's tap water: 4 ng/L, 8x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
8× 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.
Sample taken in Breuches, on the same distribution network as Baudoncourt (SIAEP DE BREUCHES). 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.
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 Baudoncourt, the 4 most closely watched PFAS (PFAS-4) add up to 4 ng/L (0.004 µg/L) at the latest PFAS check on 6 July 2026. That's 8 times our 0.5 ng/L health benchmark, exactly at Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 92 ng/L (0.092 µg/L), below the EU legal limit (100 ng/L). Sampled in Breuches, on the same network. 4 checks since 18 August 2025: PFAS-4 from 3 ng/L to 22 ng/L, averaging 11 ng/L over 12 months. Falling on the main network.

PFAS over time in Baudoncourt
5 PFAS checks since 17 March 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Baudoncourt.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Frequently asked questions
Is tap water in Baudoncourt safe to drink?
Yes. At the check on 6 July 2026, the tap water in Baudoncourt was within every limit tested. “La température de l'eau prélevée est supérieure à 25°C. Une surveillance anticipée de certains paramètres émergents, dont les per- et polyfluoroalkylées (PFAS), a été mise en place par l’ARS. Les résultats de ce suivi ont montré des valeurs supérieures à la limite d e qualité fixée à 0,1 µg/l pour la somme des PFAS. La collectivité a e ngagé, en lien avec l’ARS et la préfecture, un plan d’action pour réta blir la qualité de l’eau. Les modalités de gestion sont basées sur l’a pplication du principe de proportionnalité au regard des connaissances et expertises du moment et ne conduisent pas, à ce stade, à prononcer des restrictions d’usages de l’eau. Pour plus d’informations sur les PFAS, vous pouvez consulter le site internet de l’ARS : https://www.bo urgogne-franche-comte.ars.sante.fr/les-pfas-en-bourgogne-franche-comte”
How high are PFAS levels in Baudoncourt's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 92 ng/L. The EU limit is 100 ng/L, so this water is at 92 % of the limit. (below the EU limit)
Does the water in Baudoncourt 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 4 ng/L stays below.
Are PFAS levels rising in Baudoncourt's tap water?
No, they are falling. On the main network, the PFAS-4 sum went from 15 ng/L (18 August 2025) to 4 ng/L (6 July 2026) across 4 quantified checks. These history statistics use laboratory-published sums only.
How hard is the water in Baudoncourt?
The water hardness in Baudoncourt is 12.6 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
