PFAS in drinking water

4× above our health benchmark

Amount found in the water 2 ng/L 0.002 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.

The PFAS figures come from "Productielocatie Berenplaat", the one with the highest latest published PFAS-4 value among the 2 production locations or delivery series serving Rotterdam. The others are in the table of all values; the tap often carries a blend of several locations.

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 Rotterdam, the 4 most closely watched PFAS (PFAS-4) add up to 2 ng/L (0.002 µg/L) at the latest PFAS check on 31 August 2026. That's 4 times our 0.5 ng/L health benchmark, but below Sweden's legal limit of 4 ng/L. Sum of 20 PFAS: 15.4 ng/L (0.0154 µg/L), below the EU legal limit (100 ng/L). 11 checks since 30 September 2025: PFAS-4 from 1.4 ng/L to 2.6 ng/L, averaging 1.93 ng/L over 12 months. No clear trend. Source: Evides Waterbedrijf, rapport PFAS per productielocatie.

For comparison, RIVM advises 4.4 ng/L PFOA equivalents. That's a weighted sum, a different measure from our sum of four PFAS (PFOA, PFOS, PFNA, PFHxS) with its 0.5 ng/L benchmark.

Frequently asked questions

Is tap water in Rotterdam safe to drink?

All the values shown here (31 August 2026) are within the legal limits, but the authorities have not published an overall verdict for this water.

How high are PFAS levels in Rotterdam's drinking water?

The total of 20 PFAS ("forever chemicals") was last measured at 15.4 ng/L. The EU limit is 100 ng/L, so this water is at 15 % of the limit. (below the EU limit)

Does the water in Rotterdam 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 2 ng/L stays below.

Are PFAS levels rising in Rotterdam's tap water?

No clear trend. Since 30 September 2025, 11 checks have been published; on the main network the PFAS-4 sum ranged between 1.4 ng/L and 2.6 ng/L (11 quantified values), at times below the detection limit. pfasnearme only reports a trend from a change of at least 25 % and 1 ng/L.

Which PFAS limits apply in the Netherlands?

The Netherlands applies the EU limit of 100 ng/L for the sum of 20 PFAS in the Drinkwaterbesluit. The RIVM advises a health-based value of 4.4 ng PEQ/L (PFOA equivalents) for all PFAS together; that is an advisory, not a limit. There is no national PFAS-4 limit; the health reference is EFSA's 4 ng/L. This site's 0.5 ng/L benchmark is stricter than all three.

How hard is the water in Rotterdam?

No hardness value is available for Rotterdam in this source.

Where does this data come from?

All values come from official publications: Evides Waterbedrijf, rapport PFAS per productielocatie. Retrieved on 28 September 2026.

Same water network

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

De PFAS-4-waarde is Evides' "Som EFSA-4" (PFOA, PFOS, PFNA, PFHxS) van de laatste maand, de som van 20 is "Som EDR20 + NL2" (de 20 stoffen van de Europese drinkwaterrichtlijn plus DONA en HFPO-DA). De afzonderlijke stoffen zijn gemiddelden over de rapportperiode; 0,0 betekent niet aangetoond. Voor Rotterdam zijn 2 locaties bekend (Productielocatie Berenplaat, Productielocatie Kralingen). De PFAS-waarde van de pagina komt van Productielocatie Berenplaat, de locatie met de hoogste PFAS-4-waarde; de overige locaties staan in de tabel. Overige parameters: RIVM, INSPIRE drinkwaterkwaliteit, jaargemiddelden 2025 per pompstation; een 0 betekent niet aangetoond boven de detectiegrens.
