PFAS in Samerey's tap water: 9.4 ng/L, 18.8x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
18.8× 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 Échenon, on the same distribution network as Samerey (SIAEPA DU PAYS LOSNAIS). 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 Samerey, the 4 most closely watched PFAS (PFAS-4) add up to 9.4 ng/L (0.0094 µg/L) at the latest PFAS check on 22 June 2026. That's 18.8 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 13.5 ng/L (0.0135 µg/L), below the EU legal limit (100 ng/L). Sampled in Échenon, on the same network. 2 checks since 4 November 2025: PFAS-4 from 7 ng/L to 9.4 ng/L. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

PFAS over time in Samerey
5 PFAS checks since 4 June 2024, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Samerey.
“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 |
|---|---|---|---|
| 9.4 ng/L | 13.5 ng/L | Échenon | |
| 7 ng/L | 10.29 ng/L | Saint-Jean-de-Losne | |
| 6.4 ng/L – < 7.9 ng/L · calculated | 15.85 ng/L | Saint-Jean-de-Losne | |
| 8.5 ng/L – < 10 ng/L · calculated | 18.27 ng/L | Saint-Jean-de-Losne | |
| 6.1 ng/L – < 7.6 ng/L · calculated | 18.95 ng/L | Saint-Jean-de-Losne |
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 Samerey safe to drink?
Yes. At the check on 22 June 2026, the tap water in Samerey was within every limit tested. Outside a reference value: Coliform bacteria 4 n/(100mL) on 15 January 2025 (reference ≤ 0 mL)). These are indicator parameters with reference values, not legal limits. “Référence de qualité non satisfaite (indicateur de qualité) sur le par amètre suivant : Bactéries coliformes. Absence de chlore libre : des mesures correctives doivent être prises immédiatement pour ajuster la désinfection.”
How high are PFAS levels in Samerey's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 13.5 ng/L. The EU limit is 100 ng/L, so this water is at 13 % of the limit. (below the EU limit)
Does the water in Samerey also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 9.4 ng/L. That is 2.4 times Sweden's legal limit of 4 ng/L, in force since 2026. Germany will set a similar one in 2028. The water still passes the current EU legal limit (100 ng/L for the total of 20 PFAS).
Are PFAS levels rising in Samerey's tap water?
Too few quantified checks to say (2 since 4 June 2024). 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 Samerey?
No hardness value is available for Samerey in this source.
Where does this data come from?
