PFAS in Quincieux's tap water: 29 ng/L, 58x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
58× 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 Dommartin, on the same distribution network as Quincieux (ML VAL D'AZERGUES). 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.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).

In Quincieux, the 4 most closely watched PFAS (PFAS-4) add up to 29 ng/L (0.029 µg/L) at the latest PFAS check on 7 May 2026. That's 58 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 Dommartin, on the same network. 4 checks since 19 January 2026: PFAS-4 from 29 ng/L to 34 ng/L. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).
Details and sources
PFAS over time in Quincieux
11 PFAS checks since 25 April 2023, from the published measurements. Samples from 5 communes on the same network: it's the same water, so each one applies to Quincieux. Samples come from 2 distribution networks. The trend refers to the network “METROPOLE LYON VAL D'AZERGUES”.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Frequently asked questions
Is tap water in Quincieux safe to drink?
Yes. At the check on 5 June 2026, the tap water in Quincieux 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 Quincieux'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 Quincieux also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 29 ng/L. That is 7.3 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 Quincieux's tap water?
Too few quantified checks to say (0 since 25 April 2023). pfasnearme adds each new publication weekly; a trend needs at least three quantified values. These history statistics use laboratory-published sums only.
How hard is the water in Quincieux?
The water hardness in Quincieux is 25.5 °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 12 September 2026.
Same water network
Same distribution network as Quincieux, so in principle the same water.
