PFAS in Soissons's tap water: 8 ng/L, 16x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
16× 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 Villeneuve-Saint-Germain, on the same distribution network as Soissons (UDI DE SOISSONS - VILLENEUVE). 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).
More PFAS than in 95% of the cities we track

In Soissons, the 4 most closely watched PFAS (PFAS-4) add up to 8 ng/L (0.008 µg/L) at the latest PFAS check on 10 February 2026. That's 16 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 14 ng/L (0.014 µg/L), below the EU legal limit (100 ng/L). Sampled in Villeneuve-Saint-Germain, on the same network. 3 checks since 18 September 2025: PFAS-4 from 8 ng/L to 32 ng/L, averaging 22.33 ng/L over 12 months. Falling on the main network.

PFAS over time in Soissons
8 PFAS checks since 13 February 2024, from the published measurements. Samples from 2 communes on the same network: it's the same water, so each one applies to Soissons.
“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 Soissons safe to drink?
Yes. At the check on 19 June 2026, the tap water in Soissons 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 Soissons's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 14 ng/L. The EU limit is 100 ng/L, so this water is at 14 % of the limit. (below the EU limit)
Does the water in Soissons also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 8 ng/L. That is 2 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 Soissons's tap water?
No, they are falling. On the main network, the PFAS-4 sum went from 27 ng/L (18 September 2025) to 8 ng/L (10 February 2026) across 3 quantified checks. These history statistics use laboratory-published sums only.
How hard is the water in Soissons?
The water hardness in Soissons is 42.4 °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 12 September 2026.
