PFAS in Les Éparres's tap water: 52 ng/L, 104x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
104× 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.
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 Les Éparres, the 4 most closely watched PFAS (PFAS-4) add up to 52 ng/L (0.052 µg/L) at the latest PFAS check on 10 June 2026. That's 104 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 71 ng/L (0.071 µg/L), below the EU legal limit (100 ng/L). 7 checks since 13 August 2025: PFAS-4 from 25 ng/L to 53 ng/L, averaging 42.2 ng/L over 12 months.

Frequently asked questions
Is tap water in Les Éparres safe to drink?
All the values shown here (10 June 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”
How high are PFAS levels in Les Éparres's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 71 ng/L. The EU limit is 100 ng/L, so this water is at 71 % of the limit. (below the EU limit)
Does the water in Les Éparres also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 52 ng/L. That is 13 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 Les Éparres's tap water?
Yes. On the main network, the PFAS-4 sum rose from 30 ng/L (13 August 2025) to 53 ng/L (10 June 2026) across 5 quantified checks. pfasnearme's benchmark is 0.5 ng/L as an annual mean.
How hard is the water in Les Éparres?
The water hardness in Les Éparres is 29.1 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
