PFAS in the tap water of Sancourt (Nord): 5 ng/L, 10x our 0.5 ng/L benchmark
Last PFAS check: · Source: Hub'eau
PFAS in drinking water
10× 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.
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 Sancourt, the 4 most closely watched PFAS (PFAS-4) add up to 5 ng/L (0.005 µg/L) at the latest PFAS check on 30 April 2026. That's 10 times our 0.5 ng/L health benchmark, and above Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 40 ng/L (0.04 µg/L), below the EU legal limit (100 ng/L). 3 checks since 7 August 2025: PFAS-4 from 2 ng/L to 5 ng/L, averaging 3.67 ng/L over 12 months. Rising on the main network.

Frequently asked questions
Is tap water in Sancourt safe to drink?
All the values shown here (11 May 2026) are within the legal limits, but the authorities have not published an overall verdict for this water. “Cette eau d'alimentation respecte les exigences de qualité réglementaires pour les paramètres mesurés mais ne respecte pas les recommandations en vigueur concernant la teneur en ions perchlorates. Sa consommation est donc déconseillée pour les nourrissons de moins de 6 mois, les femmes enceintes et les femmes qui allaitent.”
How high are PFAS levels in Sancourt's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 40 ng/L. The EU limit is 100 ng/L, so this water is at 40 % of the limit. (below the EU limit)
Does the water in Sancourt also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 5 ng/L. That is 1.25 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 Sancourt's tap water?
Yes. On the main network, the PFAS-4 sum rose from 2 ng/L (7 August 2025) to 5 ng/L (30 April 2026) across 3 quantified checks. pfasnearme's benchmark is 0.5 ng/L as an annual mean. These history statistics use laboratory-published sums only.
How hard is the water in Sancourt?
The water hardness in Sancourt is 35 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.
