More about this result
PFAS-4 is not published for this supply area
Sum of 20 PFAS: 0.34 ng/L (0.0003 µg/L), 0.3 % of the 100 ng/L legal limit, sampled 17 February 2026.
Values from Keihärinkoski-Valkeisjärvi vesiosuuskunta, one of 11 supply areas serving Viitasaari; 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.

Values to watch
These results are close to their legal limit, or over it.
One routine sample was outside a limit: Coliform bacteria 1 n/(100mL) on 28 July 2026 (limit ≤ 0 n/(100mL)). This is a single result, not an official verdict on the supply.

Frequently asked questions
Is tap water in Viitasaari safe to drink?
The authorities have not published an overall verdict for this water. One routine sample was outside a limit: Coliform bacteria 1 n/(100mL) on 28 July 2026 (limit ≤ 0 n/(100mL)). This is a single result, not an official verdict on the supply. 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 Viitasaari's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.34 ng/L. The EU limit is 100 ng/L, so this water is at 0.3 % 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 Viitasaari?
The water hardness in Viitasaari is 0.1 mmol/L (soft). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?

Sivun PFAS-luku on alueelta "Keihärinkoski-Valkeisjärvi vesiosuuskunta" (korkein mitattu PFAS-yhdisteiden summa kunnan 8 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.
