PFAS in Vaugneray's tap water: 25 ng/L, 50x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
50× 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 Chevinay, on the same distribution network as Vaugneray (YZERON BOURG). 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).
More PFAS than in 99% of the cities we track

In Vaugneray, the 4 most closely watched PFAS (PFAS-4) add up to 25 ng/L (0.025 µg/L) at the latest PFAS check on 3 June 2026. That's 50 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 69 ng/L (0.069 µg/L), below the EU legal limit (100 ng/L). Sampled in Chevinay, on the same network. 6 checks since 14 October 2025: PFAS-4 from 21 ng/L to 32 ng/L, averaging 25.6 ng/L over 12 months. Falling on the main network.

Frequently asked questions
Is tap water in Vaugneray safe to drink?
Yes. At the check on 5 June 2026, the tap water in Vaugneray 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 Vaugneray's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 69 ng/L. The EU limit is 100 ng/L, so this water is at 69 % of the limit. (below the EU limit)
Does the water in Vaugneray also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 25 ng/L. That is 6.3 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 Vaugneray's tap water?
No, they are falling. On the main network, the PFAS-4 sum went from 32 ng/L (14 October 2025) to 21 ng/L (5 May 2026) across 5 quantified checks. These history statistics use laboratory-published sums only.
How hard is the water in Vaugneray?
The water hardness in Vaugneray is 30.9 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
