PFAS in drinking water

20× above our health benchmark

Amount found in the water 10 ng/L 0.01 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 Lyon, on the same distribution network as Charly (CENTRE (METROPOLE LYON)). 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).

More PFAS than in 96% of the cities we track

Frequently asked questions

Is tap water in Charly safe to drink?

Yes. At the check on 16 July 2026, the tap water in Charly 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 Charly's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 17 ng/L. The EU limit is 100 ng/L, so this water is at 17 % of the limit. (below the EU limit)

Does the water in Charly also meet the strictest limits in Europe?

No. The four most harmful PFAS add up to 10 ng/L. That is 2.5 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 Charly's tap water?

No clear trend. Since 28 February 2023, 20 checks have been published; on the main network the PFAS-4 sum ranged between 4 ng/L and 17 ng/L (16 quantified values), at times below the detection limit. pfasnearme only reports a trend from a change of at least 25 % and 1 ng/L. These history statistics use laboratory-published sums only.

How hard is the water in Charly?

The water hardness in Charly is 19.3 °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.

Same water network

Same distribution network as Charly, so in principle the same water.
