PFAS in drinking water

62× above our health benchmark

Amount found in the water 31 ng/L 0.031 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.

Sample taken in Aumur, on the same distribution network as Gevry (SIE RECEPAGE - SECTEUR TAVAUX). 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 Gevry, the 4 most closely watched PFAS (PFAS-4) add up to 31 ng/L (0.031 µg/L) at the latest PFAS check on 30 March 2026. That's 62 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 48 ng/L (0.048 µg/L), below the EU legal limit (100 ng/L). Sampled in Aumur, on the same network. 5 checks since 26 August 2025: PFAS-4 from 31 ng/L to 51 ng/L, averaging 43 ng/L over 12 months. Falling on the main network.

PFAS over time in Gevry

15 PFAS checks since 4 September 2024, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Gevry.

“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 Gevry safe to drink?

Yes. At the check on 6 May 2026, the tap water in Gevry 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 Gevry's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 48 ng/L. The EU limit is 100 ng/L, so this water is at 48 % of the limit. (below the EU limit)

Does the water in Gevry also meet the strictest limits in Europe?

No. The four most harmful PFAS add up to 31 ng/L. That is 7.8 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 Gevry's tap water?

No, they are falling. On the main network, the PFAS-4 sum went from 43 ng/L (26 August 2025) to 31 ng/L (30 March 2026) across 5 quantified checks. These history statistics use laboratory-published sums only.

How hard is the water in Gevry?

The water hardness in Gevry is 25.3 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?

All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 12 September 2026.

Same water network

Same distribution network as Gevry, so in principle the same water.
