PFAS in Tholen's tap water: none of the four main PFAS detected

PFAS in drinking water

not precise enough to compare

Amount found in the water PFAS-4 not detected the 4 most harmful PFAS (PFAS-4)
Our health benchmark 0.5 ng/L

Some of the four PFAS were too small for the lab to measure. The check cannot say whether this water is above or below our benchmark of 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 Halsteren".

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.

In Tholen, none of the 4 most closely watched PFAS (PFAS-4) was found in a measurable amount at the latest PFAS check on 31 May 2026. That's below the detection limit, so there's no verdict against our 0.5 ng/L benchmark. Sum of 20 PFAS: not detected, below the EU legal limit (100 ng/L). 3 checks since 30 November 2025, PFAS-4 always below the detection limit. 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 Tholen safe to drink?

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

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

At the latest check the total of 20 PFAS ("forever chemicals") was reported as not detected; the laboratory did not state its reporting limit. The EU limit is 100 ng/L. (below the EU limit)

Does the water in Tholen also meet the strictest limits in Europe?

The check cannot say. None of the four compounds was quantified, and the source does not publish detection limits fine enough to compare their total with Sweden's legal limit of 4 ng/L in force since 2026.

Are PFAS levels rising in Tholen's tap water?

No. Since 30 November 2025, 3 checks have been published and the PFAS-4 sum stayed below the laboratory's detection limit every time.

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 Tholen?

No hardness value is available for Tholen in this source.

Where does this data come from?

Evides Waterbedrijf: PFAS report per production location, monthly means of the EFSA-4 sum, the sum of 20 PFAS (EDR20 + NL2) and the PEQ sum (one PDF per location; Midden-Zeeland as delivered blended water) (monthly). Latest value dated 31 May 2026. Evides updates the reports monthly; the next monthly column appears within a few weeks of the end of the month.

Limits 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.
