PFAS in drinking water

PFAS-4 is not published for this supply area

More about this result

No PFAS result is published for Bergen in the data retrieved on 28 September 2026 (Mattilsynet, Vannverk (vannforsyningssystem_analyse)). PFAS testing of drinking water has been mandatory across the EU since January 2026. The latest published check dates from 31 December 2025.

The four EFSA compounds (PFOA, PFOS, PFNA, PFHxS) are not reported separately, so the 4 ng/L health benchmark and this site's 0.5 ng/L benchmark cannot be checked.

Sum-4 PFAS at 4 ng/L applies since 1 January 2026; analysis is mandatory only where the hazard assessment shows PFAS may occur; first annual figures are due 15 February 2027.

Values to watch

These results are close to their legal limit, or over it.

In 2025, at least one sample fell outside the limit for Enterococci 16 n/(100mL) (limit ≤ 0 n/(100mL)), Coliform bacteria 28 n/(100mL) (limit ≤ 0 n/(100mL)), Colony count at 22 °C 300 n/mL (limit ≤ 100 n/mL), Aluminium 0.3 mg/L (limit ≤ 0.2 mg/L). The annual medians were within every limit.

Frequently asked questions

Is tap water in Bergen safe to drink?

The authorities have not published an overall verdict for this water. In 2025, at least one sample fell outside the limit for Enterococci 16 n/(100mL) (limit ≤ 0 n/(100mL)), Coliform bacteria 28 n/(100mL) (limit ≤ 0 n/(100mL)), Colony count at 22 °C 300 n/mL (limit ≤ 100 n/mL), Aluminium 0.3 mg/L (limit ≤ 0.2 mg/L). The annual medians were within every limit. The four EFSA compounds (PFAS-4) are not itemised, so this water cannot be compared with the 0.5 ng/L health benchmark used by pfasnearme.

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

No PFAS results have been published for Bergen yet. Testing has been required across the EU since January 2026. We will show the values here as soon as they come out.

Which PFAS limits apply in Norway?

Norway's drikkevannsforskriften, vedlegg 1, sets "Sum 4 PFAS" (PFOA, PFOS, PFNA, PFHxS) at 0.004 µg/l, that is 4 ng/L, added by forskrift 2025-12-19-2728 and in force since 1 January 2026; waterworks report their annual figures by 15 February of the following year. The regulation contains no limit for the sum of 20 PFAS today. This site's 0.5 ng/L benchmark is stricter than the Norwegian limit.

How hard is the water in Bergen?

No hardness value is available for Bergen in this source.

Where does this data come from?

All values come from official publications: Mattilsynet, Vannverk (vannforsyningssystem_analyse). Retrieved on 28 September 2026.

Årstall fra Mattilsynets vannverksregister (data per 2026-09-27, uttrekk 28.09.2026 02:11). Verdiene er median og høyeste målte verdi for 2025 i drikkevannet fra Bergen Vannverk (264 000 fastboende), det største av kommunens 5 aktive vannforsyningssystemer med analyser for 2025 eller 2024; de øvrige er listet under vannforsyningssystemer. Antall prøver bak hvert tall varierer. Enheter er ikke oppgitt i uttrekket og følger Mattilsynets feltbeskrivelse og drikkevannsforskriften vedlegg 1; "overskridelse" betyr at minst én prøve i 2025 overskred grenseverdien (ant_avvik).
