PFAS in Nevers's tap water: 3 ng/L, 6x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
6× 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 Challuy, on the same distribution network as Nevers (CHALLUY GIMOUILLE SERMOISE). 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 88% of the cities we track

In Nevers, the 4 most closely watched PFAS (PFAS-4) add up to 3 ng/L (0.003 µg/L) at the latest PFAS check on 19 June 2026. That's 6 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 7 ng/L (0.007 µg/L), below the EU legal limit (100 ng/L). Sampled in Challuy, on the same network. 5 checks since 4 November 2025: PFAS-4 from 1 ng/L to 3 ng/L, averaging 1 ng/L over 12 months. No clear trend.

Details and sources
PFAS over time in Nevers
7 PFAS checks since 31 October 2024, from the published measurements. Samples from 3 communes on the same network: it's the same water, so each one applies to Nevers. Samples come from 2 distribution networks. The trend refers to the network “NEVERS VARENNES VAUZELLES”.
“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 Nevers safe to drink?
Yes. At the check on 23 July 2026, the tap water in Nevers was within every limit tested. “La teneur en chlore est insuffisante pour garantir une désinfection ef ficace de l’eau distribuée sur l’ensemble du réseau comme le démontre la présence de bactéries revivifiables. Il est recommandé de mainteni r au moins 0,1 mg/L en tout point du réseau. Les autres paramètres me surés répondent aux normes de potabilité.”
How high are PFAS levels in Nevers's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 7 ng/L. The EU limit is 100 ng/L, so this water is at 7 % of the limit. (below the EU limit)
Does the water in Nevers 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 3 ng/L stays below.
Are PFAS levels rising in Nevers's tap water?
No clear trend. Since 31 October 2024, 5 checks have been published; on the main network the PFAS-4 sum ranged between 1 ng/L and 1 ng/L (4 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 Nevers?
The water hardness in Nevers is 11.6 °f (soft). 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.
