PFAS in Varennes-sous-Dun's tap water: 14 ng/L, 28x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
28× 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 Amanzé, on the same distribution network as Varennes-sous-Dun (BRIONNAIS-VINDECY-BAUGY). 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 Varennes-sous-Dun, the 4 most closely watched PFAS (PFAS-4) add up to 14 ng/L (0.014 µg/L) at the latest PFAS check on 9 March 2026. That's 28 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 14 ng/L (0.014 µg/L), below the EU legal limit (100 ng/L). Sampled in Amanzé, on the same network. 3 checks since 19 January 2026: PFAS-4 from 2 ng/L to 14 ng/L, averaging 8 ng/L over 12 months. Rising on the main network.

Frequently asked questions
Is tap water in Varennes-sous-Dun safe to drink?
Yes. At the check on 9 March 2026, the tap water in Varennes-sous-Dun was within every limit tested. Outside a reference value: pH 6.19 unité pH on 2 February 2026 (reference 6.5–9 unité pH), Electrical conductivity 90 µS/cm on 2 February 2026 (reference 200–1,100 µS/cm). These are indicator parameters with reference values, not legal limits. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité. Le pH et/ou la conductivité sont inférieurs à la référence de qualité. L'eau ne doit pas être agressive pour les matériaux avec lesquels elle est en contact.”
How high are PFAS levels in Varennes-sous-Dun's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 14 ng/L. The EU limit is 100 ng/L, so this water is at 14 % of the limit. (below the EU limit)
Does the water in Varennes-sous-Dun also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 14 ng/L. That is 3.5 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 Varennes-sous-Dun's tap water?
Yes. On the main network, the PFAS-4 sum rose from 8 ng/L (19 January 2026) to 14 ng/L (9 March 2026) across 3 quantified checks. pfasnearme's benchmark is 0.5 ng/L as an annual mean.
How hard is the water in Varennes-sous-Dun?
The water hardness in Varennes-sous-Dun is 2 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
