PFAS in drinking water
3.2× 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.
The PFAS figures come from the sample of 17 December 2025 in distribution zone ZW1363 (SWDE), one of the 6 zones serving Binche.
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 Binche, the 4 most closely watched PFAS (PFAS-4) add up to 1.6 ng/L (0.0016 µg/L) at the latest PFAS check on 17 December 2025. That's 3.2 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 1.6 ng/L (0.0016 µg/L), below the EU legal limit (100 ng/L). 26 checks since 11 September 2023: PFAS-4 up to 1.6 ng/L, sometimes below the detection limit.

“<” means not detected, the figure being the detection limit. “–” means not published. Labs have only reported the PFAS-4 sum (SANDRE code 9268) since autumn 2025. How to read a PFAS result
What the latest check found
The authorities have not published an overall verdict for this water.
Frequently asked questions
Is tap water in Binche safe to drink?
All the values shown here (17 December 2025) are within the legal limits, but the authorities have not published an overall verdict for this water.
How high are PFAS levels in Binche's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 1.6 ng/L. The EU limit is 100 ng/L, so this water is at 2 % of the limit. (below the EU limit)
Does the water in Binche 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 1.6 ng/L stays below.
Are PFAS levels rising in Binche's tap water?
No. Since 11 September 2023, 26 checks have been published; on the main network the PFAS-4 sum stayed below the laboratory's detection limit (4 ng/L) every time.
Which PFAS limits apply in Belgium?
Belgium applies the EU limit of 100 ng/L for the sum of 20 PFAS as binding law (Flemish Drinkwaterbesluit of 2023, Walloon Code de l'eau since February 2025). For the four most harmful PFAS (PFAS-4) all three regions set a target of 4 ng/L that becomes binding in 2028. This site's 0.5 ng/L benchmark is stricter than both.
How hard is the water in Binche?
No hardness value is available for Binche in this source.
Where does this data come from?
All values come from official publications: SPW-ARNE / SWDE – Etat des lieux du monitoring PFAS dans les eaux distribuées (sept. 2023 – déc. 2025). Retrieved on 28 September 2026.
