PFAS in Varennes-lès-Narcy's tap water: 7 ng/L, 14x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
14× 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 La Charité-sur-Loire, on the same distribution network as Varennes-lès-Narcy (LA CHARITE SUR LOIRE). 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 Varennes-lès-Narcy, the 4 most closely watched PFAS (PFAS-4) add up to 7 ng/L (0.007 µg/L) at the latest PFAS check on 5 June 2026. That's 14 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 18 ng/L (0.018 µg/L), below the EU legal limit (100 ng/L). Sampled in La Charité-sur-Loire, on the same network. 2 checks since 17 October 2025: PFAS-4 from 1 ng/L to 7 ng/L. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).
Details and sources
PFAS over time in Varennes-lès-Narcy
4 PFAS checks since 4 February 2025, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Varennes-lès-Narcy. Samples come from 2 distribution networks. The trend refers to the network “MAZOU”.
“Calculated”: PFAS-4 worked out from the four substances in the same sample. The chart, averages and trends use lab-published sums only.

Is tap water in Varennes-lès-Narcy safe to drink?
Yes. At the check on 5 June 2026, the tap water in Varennes-lès-Narcy 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 Varennes-lès-Narcy's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 18 ng/L. The EU limit is 100 ng/L, so this water is at 18 % of the limit. (below the EU limit)
Does the water in Varennes-lès-Narcy also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 7 ng/L. That is 1.75 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-Narcy's tap water?
Too few quantified checks to say (0 since 4 February 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values. These history statistics use laboratory-published sums only.
