PFAS in drinking water
PFAS-4 is not published for this supply area
More about this result
No PFAS result is published for Senja 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.

Frequently asked questions
Is tap water in Senja safe to drink?
All the values shown here (31 December 2025) are within the legal limits, but the authorities have not published an overall verdict for this water. 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 Senja's drinking water?
No PFAS results have been published for Senja 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 Senja?
No hardness value is available for Senja 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 Finnsnes Vannverk (7 105 fastboende), det største av kommunens 33 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).
