PFAS in Tubize's tap water: 1 ng/L, 2x our 0.5 ng/L benchmark
Last PFAS check: · Source: VMM
PFAS in drinking water
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 ZW1478 (SWDE), one of the 8 zones serving Tubize. Part of Tubize is also served by Flemish supply area LG24_MW16; its 2024 annual PFAS-4 median (2 ng/L) is listed in the full results table.
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 Tubize, the 4 most closely watched PFAS (PFAS-4) add up to 1 ng/L (0.001 µg/L) at the latest PFAS check on 17 December 2025. That's 2 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 18.6 ng/L (0.0186 µg/L), below the EU legal limit (100 ng/L). 181 checks since 12 September 2023: PFAS-4 up to 35 ng/L, sometimes below the detection limit, averaging at least 4.81 ng/L over 12 months (non-detects as 0). Falling on the main network.

Frequently asked questions
Is tap water in Tubize 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 Tubize's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 18.6 ng/L. The EU limit is 100 ng/L, so this water is at 19 % of the limit. (below the EU limit)
Does the water in Tubize 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 ng/L stays below.
Are PFAS levels rising in Tubize's tap water?
No, they are falling. On the main network, the PFAS-4 sum went from 17 ng/L (21 September 2023) to 1.2 ng/L (12 September 2025) across 33 quantified checks.
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 Tubize?
The water hardness in Tubize is 44.7 Fr° (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: SPW-ARNE / SWDE – Etat des lieux du monitoring PFAS dans les eaux distribuées (sept. 2023 – déc. 2025); Vlaamse Milieumaatschappij (VMM) – Kwaliteit van het drinkwater 2024, bijlage 2. Retrieved on 28 September 2026.
Same water network
Same distribution network as Tubize, so in principle the same water.

Jaarcijfers 2024 van de metingen in het distributienet per leveringsgebied (VMM). De getoonde waarde is de mediaan van 2024; het maximum staat als aparte waarde "Maximale concentratie". 0 = niet gedetecteerd (onder de rapportagegrens). De gemeente valt in 2 leveringsgebieden (LG24_MW15, LG24_MW16); de PFAS-cijfers komen uit leveringsgebied LG24_MW16, het gebied met de hoogste mediane PFAS-4-waarde. Résultats du monitoring PFAS des eaux distribuées (SPW-ARNE, coordination SWDE), une ligne par prélèvement et zone de distribution (ZDE) ; la commune est desservie par 6 zones (ZW1105, ZW1106, ZW1107, ZW1147, ZW1167, ZW1478). Valeurs publiées en ng/L, converties en µg/L ; un « < » indique que tous les composés étaient sous la limite de quantification.
