PFAS in Joinville-le-Pont's tap water: 4 ng/L, 8x our 0.5 ng/L benchmark

Last PFAS check: · Source: Hub'eau

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.

Sample taken in Choisy-le-Roi, on the same distribution network as Joinville-le-Pont (G.CHOISY MAJORITAIRE). 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 Joinville-le-Pont, 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. 4 checks since 9 January 2026: PFAS-4 up to 2 ng/L, sometimes below the detection limit.

PFAS over time in Joinville-le-Pont

71 PFAS checks since 2 April 2025, from the published measurements. Samples from 5 communes on the same network: it's the same water, so each one applies to Joinville-le-Pont. Samples come from 3 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 Joinville-le-Pont safe to drink?

Yes. At the check on 16 July 2026, the tap water in Joinville-le-Pont 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 Joinville-le-Pont'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 Joinville-le-Pont 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 Joinville-le-Pont's tap water?

Too few quantified checks to say (0 since 2 April 2025). pfasnearme adds each new publication weekly; a trend needs at least three quantified values. These history statistics use laboratory-published sums only.

How hard is the water in Joinville-le-Pont?

The water hardness in Joinville-le-Pont is 36.5 °f (hard). 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.

Same water network

Same distribution network as Joinville-le-Pont, so in principle the same water.
