PFAS in Varennes-lès-Mâcon's tap water: 9 ng/L, 18x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
18× 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 Prissé, on the same distribution network as Varennes-lès-Mâcon (MBA LA BARGE). 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).

Frequently asked questions
Is tap water in Varennes-lès-Mâcon safe to drink?
At the latest check, the water was over at least one limit. “Eau d'alimentation conforme aux exigences de qualité en vigueur pour l'ensemble des paramètres mesurés.”
How high are PFAS levels in Varennes-lès-Mâcon's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 19 ng/L. The EU limit is 100 ng/L, so this water is at 19 % of the limit. (below the EU limit)
Does the water in Varennes-lès-Mâcon also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 9 ng/L. That is 2.3 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 Varennes-lès-Mâcon's tap water?
No clear trend. Since 6 November 2024, 3 checks have been published; on the main network the PFAS-4 sum ranged between 9 ng/L and 10 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.
