PFAS in Vincennes's tap water: 4 ng/L, 8x our 0.5 ng/L benchmark

PFAS in drinking water

8× above our health benchmark

Amount found in the water 4 ng/L 0.004 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.

How we chose 0.5 ng/L

Sample taken in Choisy-le-Roi, on the same distribution network as Vincennes (G.CHOISY MAJORITAIRE). The health authority samples one tap per network; a network carries the same treated water everywhere.

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 Vincennes, the 4 most closely watched PFAS (PFAS-4) add up to 4 ng/L (0.004 µg/L) at the latest PFAS check on 16 July 2026. That's 8 times our 0.5 ng/L health benchmark, exactly at Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 6 ng/L (0.006 µg/L), below the EU legal limit (100 ng/L). Sampled in Choisy-le-Roi, on the same network. 61 checks since 2 April 2025: sum of 20 PFAS up to 14 ng/L, sometimes below the detection limit.

PFAS over time in Vincennes

61 PFAS checks since 2 April 2025, from the published measurements. Samples from 4 communes on the same network: it's the same water, so each one applies to Vincennes. Samples come from 2 distribution networks. The trend refers to the network “G.CHOISY MAJORITAIRE”.

“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 Vincennes safe to drink?

Yes. At the check on 27 July 2026, the tap water in Vincennes was within every limit tested. “Eau d'alimentation conforme aux limites de qualité et non conforme aux références de qualité.”

How high are PFAS levels in Vincennes's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 6 ng/L. The EU limit is 100 ng/L, so this water is at 6 % of the limit. (below the EU limit)

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

Yes. Even against Europe's strictest legal limit, Sweden's 4 ng/L in force since 2026, the measured value of 4 ng/L stays below.

Are PFAS levels rising in Vincennes's tap water?

Calculated PFAS-4 values are listed in the table. The chart uses laboratory-published sum-of-20 results; there are too few laboratory-published PFAS-4 sums for the existing trend calculation.

How hard is the water in Vincennes?

The water hardness in Vincennes is 23 °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 21 September 2026.
