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.

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 Saint-Georges-d'Espéranche, the 4 most closely watched PFAS (PFAS-4) add up to 1 ng/L (0.001 µg/L) at the latest PFAS check on 28 May 2026. That's 2 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 1 ng/L (0.001 µg/L), below the EU legal limit (100 ng/L). 6 checks since 25 September 2025: PFAS-4 from 1 ng/L to 47 ng/L, averaging 17.75 ng/L over 12 months. Falling on the main network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Is tap water in Saint-Georges-d'Espéranche safe to drink?

Yes. At the check on 8 June 2026, the tap water in Saint-Georges-d'Espéranche was within every limit tested. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”

How high are PFAS levels in Saint-Georges-d'Espéranche's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 1 ng/L. The EU limit is 100 ng/L, so this water is at 1 % of the limit. (below the EU limit)

Does the water in Saint-Georges-d'Espéranche 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 1 ng/L stays below.

Are PFAS levels rising in Saint-Georges-d'Espéranche's tap water?

No, they are falling. On the main network, the PFAS-4 sum went from 47 ng/L (25 September 2025) to 13 ng/L (29 January 2026) across 4 quantified checks.

How hard is the water in Saint-Georges-d'Espéranche?
