PFAS in the tap water of Chevrières (Loire): 21 ng/L, 42x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
42× 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 Panissières, on the same distribution network as Chevrières (SI MONTS DU LYONNAIS GRIGNY). 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 Chevrières, the 4 most closely watched PFAS (PFAS-4) add up to 21 ng/L (0.021 µg/L) at the latest PFAS check on 6 January 2026. That's 42 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 57 ng/L (0.057 µg/L), below the EU legal limit (100 ng/L). Sampled in Panissières, on the same network. 5 checks since 11 September 2025: PFAS-4 from 15 ng/L to 26 ng/L, averaging 21.4 ng/L over 12 months. Rising on the main network.

Is tap water in Chevrières safe to drink?
Yes. At the check on 6 January 2026, the tap water in Chevrières 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 Chevrières's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 57 ng/L. The EU limit is 100 ng/L, so this water is at 57 % of the limit. (below the EU limit)
Does the water in Chevrières also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 21 ng/L. That is 5.3 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 Chevrières's tap water?
Yes. On the main network, the PFAS-4 sum rose from 15 ng/L (11 September 2025) to 21 ng/L (6 January 2026) across 5 quantified checks. pfasnearme's benchmark is 0.5 ng/L as an annual mean. These history statistics use laboratory-published sums only.
