PFAS in drinking water

6× above our health benchmark

Amount found in the water 3 ng/L 0.003 µg/L · the 4 most harmful PFAS (PFAS-4)
Our health benchmark 0.5 ng/L

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 Brassac-les-Mines, on the same distribution network as Jumeaux (PONT DE JUMEAUX (RIVE GAUCHE)). 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 Jumeaux, the 4 most closely watched PFAS (PFAS-4) add up to 3 ng/L (0.003 µg/L) at the latest PFAS check on 9 July 2026. That's 6 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 3 ng/L (0.003 µg/L), below the EU legal limit (100 ng/L). Sampled in Brassac-les-Mines, on the same network. 4 checks since 30 September 2025: PFAS-4 up to 3 ng/L, sometimes below the detection limit.

PFAS over time in Jumeaux

4 PFAS checks since 30 September 2025, values as published. Samples from 3 communes on the same network: it's the same water, so each one applies to Jumeaux. Samples come from 2 distribution networks. The trend refers to the network “JUMEAUX BOURG (RIVE DROITE)”.

Frequently asked questions

Is tap water in Jumeaux safe to drink?

Yes. At the check on 9 July 2026, the tap water in Jumeaux was within every limit tested. Outside a reference value: Electrical conductivity 98 µS/cm on 9 July 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité.”

How high are PFAS levels in Jumeaux's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 3 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 Jumeaux 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 3 ng/L stays below.

Are PFAS levels rising in Jumeaux's tap water?

No. Since 30 September 2025, 4 checks have been published; on the main network the PFAS-4 sum stayed below the laboratory's detection limit (4 ng/L) every time.

How hard is the water in Jumeaux?

The water hardness in Jumeaux is 2 °f (soft). 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.
