PFAS in the tap water of Les Ormes (Vienne): 4 ng/L, 8x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
8× 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 Vaux-sur-Vienne, on the same distribution network as Les Ormes (VAUX SV VAUX). 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 Les Ormes, the 4 most closely watched PFAS (PFAS-4) add up to 4 ng/L (0.004 µg/L) at the latest PFAS check on 21 May 2026. That's 8 times our 0.5 ng/L health benchmark, exactly at Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 7.2 ng/L (0.0072 µg/L), below the EU legal limit (100 ng/L). Sampled in Vaux-sur-Vienne, on the same network. 4 checks since 22 May 2025: PFAS-4 from 1.8 ng/L to 5.6 ng/L, averaging 3.33 ng/L over 12 months. Rising on the main network.

Frequently asked questions
Is tap water in Les Ormes safe to drink?
Yes. At the check on 21 May 2026, the tap water in Les Ormes 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 Les Ormes's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 7.2 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 Les Ormes 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 4 ng/L stays below.
Are PFAS levels rising in Les Ormes's tap water?
Yes. On the main network, the PFAS-4 sum rose from 1.9 ng/L (22 May 2025) to 4 ng/L (21 May 2026) across 4 quantified checks. pfasnearme's benchmark is 0.5 ng/L as an annual mean.
How hard is the water in Les Ormes?
The water hardness in Les Ormes is 17 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
