PFAS in Sainte-Anne-sur-Gervonde's tap water: 42 ng/L, 84x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
84× 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 Tramolé, on the same distribution network as Sainte-Anne-sur-Gervonde (PONT ECLOSE CCBI). 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).

PFAS over time in Sainte-Anne-sur-Gervonde
6 PFAS checks since 16 July 2025, from the published measurements. Samples from 4 communes on the same network: it's the same water, so each one applies to Sainte-Anne-sur-Gervonde. Samples come from 2 distribution networks. The trend refers to the network “CARLOZ”.
“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 Sainte-Anne-sur-Gervonde safe to drink?
Yes. At the check on 2 June 2026, the tap water in Sainte-Anne-sur-Gervonde 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 Sainte-Anne-sur-Gervonde's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 60 ng/L. The EU limit is 100 ng/L, so this water is at 60 % of the limit. (below the EU limit)
Does the water in Sainte-Anne-sur-Gervonde also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 42 ng/L. That is 10.5 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 Sainte-Anne-sur-Gervonde's tap water?
No clear trend. Since 16 July 2025, 5 checks have been published; on the main network the PFAS-4 sum ranged between 2 ng/L and 2 ng/L (3 quantified values), at times below the detection limit. pfasnearme only reports a trend from a change of at least 25 % and 1 ng/L. These history statistics use laboratory-published sums only.
How hard is the water in Sainte-Anne-sur-Gervonde?
The water hardness in Sainte-Anne-sur-Gervonde is 30.4 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
