PFAS in Saint-Michel-sur-Rhône's tap water: 8 ng/L, 16x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
16× 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.
More about this result
The US also limits PFOA and PFOS to 4 ng/L each, per substance.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

In Saint-Michel-sur-Rhône, the 4 most closely watched PFAS (PFAS-4) add up to 8 ng/L (0.008 µg/L) at the latest PFAS check on 21 May 2026. That's 16 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 18 ng/L (0.018 µg/L), below the EU legal limit (100 ng/L). 7 checks since 18 September 2025: PFAS-4 from 7 ng/L to 12 ng/L, averaging 8.57 ng/L over 12 months. Falling on the main network. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions
Is tap water in Saint-Michel-sur-Rhône safe to drink?
Yes. At the check on 23 July 2026, the tap water in Saint-Michel-sur-Rhône was within every limit tested. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité.”
How high are PFAS levels in Saint-Michel-sur-Rhône's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 18 ng/L. The EU limit is 100 ng/L, so this water is at 18 % of the limit. (below the EU limit)
Does the water in Saint-Michel-sur-Rhône also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 8 ng/L. That is 2 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 Saint-Michel-sur-Rhône's tap water?
No, they are falling. On the main network, the PFAS-4 sum went from 12 ng/L (18 September 2025) to 8 ng/L (21 May 2026) across 7 quantified checks. These history statistics use laboratory-published sums only.
How hard is the water in Saint-Michel-sur-Rhône?
The water hardness in Saint-Michel-sur-Rhône is 18.4 °f (medium). 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.
