More about this result
PFAS-4 is not published for this supply area
Sum of 20 PFAS: 0.8 ng/L (0.0008 µg/L), 0.8 % of the 100 ng/L legal limit, sampled 28 January 2025.
Values from Korsnäs kommuns vattentjänstverk, one of 2 supply areas serving Korsnäs; the others are in the table.
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.
PFAS-20 monitoring is mandatory since 12 January 2026; 158 of 287 municipalities have a published result so far.
Within the legal limit. This source does not report the four main PFAS separately.

Frequently asked questions
Is tap water in Korsnäs safe to drink?
All the values shown here (25 August 2026) 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 Korsnäs's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.8 ng/L. The EU limit is 100 ng/L, so this water is at 0.8 % of the limit. (below the EU limit)
Which PFAS limits apply in Finland?
Finland applies decree STM 1352/2015 of the Ministry of Social Affairs and Health as amended by 2/2023: "PFAS-aineiden summa" (sum of 20 PFAS) at most 0.10 µg/l, that is 100 ng/L, applied from 12 January 2026. There is no national PFAS-4 limit; Sweden applies 4 ng/L. This site's 0.5 ng/L benchmark is stricter than both.
How hard is the water in Korsnäs?
The water hardness in Korsnäs is 0.5 mmol/L (soft). This mainly matters for household appliances and detergent dosing, not for health.

Sivun PFAS-luku on alueelta "Korsnäs kommuns vattentjänstverk" (korkein mitattu PFAS-yhdisteiden summa kunnan 2 PFAS-tuloksesta); muut alueet ovat taulukossa. PFAS-yhdisteiden summan (20 yhdistettä) raja-arvo on 0,10 µg/l (STM 1352/2015, muutos 2/2023, sovellettu 12.1.2026 alkaen). Neljän EFSA-yhdisteen summaa (PFAS-4) ei julkaista. Rajapinta julkaisee kunkin muuttujan uusimman tuloksen; taulukon arvo on korkein kunnan alueilta viimeisten 24 kuukauden aikana julkaistu tulos (vanhempi tulos vain, jos uudempaa ei ole), alue on merkitty riville.
