PFAS in Villefranche-sur-Saône's tap water: under 4 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
None of the 4 most harmful PFAS detected
The lab sees nothing below 4 ng/L, 8 times our benchmark of 0.5 ng/L. Water above our benchmark would pass this check unnoticed.
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 Denicé, on the same distribution network as Villefranche-sur-Saône (COMMUNAUTE D'AGGLO VILLEFRANCHE). 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.
The lab detects each of the four substances from 1 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

In Villefranche-sur-Saône, none of the 4 most closely watched PFAS (PFAS-4) was detected at the latest PFAS check on 30 July 2026. The total is below 4 ng/L, the sum of the detection limits and 8 times our 0.5 ng/L benchmark. Sum of 20 PFAS: 1 ng/L (0.001 µg/L), below the EU legal limit (100 ng/L). Sampled in Denicé, on the same network. 5 checks since 1 December 2025: PFAS-4 up to 31 ng/L, sometimes below the detection limit, averaging at least 13.75 ng/L over 12 months (non-detects as 0). No clear trend. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions
Is tap water in Villefranche-sur-Saône safe to drink?
Yes. At the check on 30 July 2026, the tap water in Villefranche-sur-Saône 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 Villefranche-sur-Saône's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 1 ng/L. The EU limit is 100 ng/L, so this water is at 1 % of the limit. (below the EU limit)
Does the water in Villefranche-sur-Saône also meet the strictest limits in Europe?
As far as this check can tell, yes. None of the four compounds was quantified, so their total is below 4 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.
Are PFAS levels rising in Villefranche-sur-Saône's tap water?
No clear trend. Since 8 March 2023, 5 checks have been published; on the main network the PFAS-4 sum ranged between 9 ng/L and 31 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 Villefranche-sur-Saône?
The water hardness in Villefranche-sur-Saône is 30.6 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
