PFAS in drinking water

12× above our health benchmark

Amount found in the water 6 ng/L 0.006 µg/L · the 4 most harmful PFAS (PFAS-4)
Our health benchmark 0.5 ng/L

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.

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 Ayvelles, the 4 most closely watched PFAS (PFAS-4) add up to 6 ng/L (0.006 µg/L) at the latest PFAS check on 24 July 2026. That's 12 times our 0.5 ng/L health benchmark, and above 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). 3 checks since 1 April 2025: sum of 20 PFAS up to 10 ng/L, sometimes below the detection limit.

PFAS over time in Les Ayvelles

3 PFAS checks since 1 April 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Les Ayvelles.

“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 Les Ayvelles safe to drink?

All the values shown here (24 July 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “Eau d’alimentation non conforme à la limite de qualité réglementaire pour les paramètres chloridazone desphenyl mais sans dépasser la valeur dérogatoire. L’eau peut être consommée par tous. Un contrôle renforcé est en place et des actions sont à engager par l’exp loitant pour restaurer la qualité de l’eau.”

How high are PFAS levels in Les Ayvelles'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 Les Ayvelles also meet the strictest limits in Europe?

No. The four most harmful PFAS add up to 6 ng/L. That is 1.5 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 Les Ayvelles's tap water?

Calculated PFAS-4 values are listed in the table. The chart uses laboratory-published sum-of-20 results; there are too few laboratory-published PFAS-4 sums for the existing trend calculation.

How hard is the water in Les Ayvelles?

The water hardness in Les Ayvelles is 21.9 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?
