PFAS in Soindres'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.

Sample taken in Buchelay, on the same distribution network as Soindres (BUCHELAY MAGNANVILLE SOINDRES ROSNY). 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 Soindres, the 4 most closely watched PFAS (PFAS-4) add up to 4 ng/L (0.004 µg/L) at the latest PFAS check on 19 March 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: 11 ng/L (0.011 µg/L), below the EU legal limit (100 ng/L). Sampled in Buchelay, on the same network. 5 checks since 10 April 2025: sum of 20 PFAS from 10 ng/L to 18 ng/L. Source: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM).

Frequently asked questions

Is tap water in Soindres safe to drink?

Yes. At the check on 16 June 2026, the tap water in Soindres 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 Soindres's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 11 ng/L. The EU limit is 100 ng/L, so this water is at 11 % of the limit. (below the EU limit)

Does the water in Soindres 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 Soindres'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 Soindres?

The water hardness in Soindres is 23.9 °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 12 September 2026.

Same water network

Same distribution network as Soindres, so in principle the same water.
