PFAS in drinking water

More about this result

PFAS-4 is not published for this supply area

Sum of 20 PFAS below the laboratory's reporting limit (<30 ng/L), sampled 11 June 2026.

Values from HSY:n vesihuolto, one of 6 supply areas serving Vantaa; 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.

The four main PFAS are not published here. Sign up below and we will tell you when they are.

In Vantaa, the latest published PFAS-20 result is below the laboratory's reporting limit (<30 ng/L), sampled 11 June 2026, under the EU legal limit of 100 ng/L. 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.

Frequently asked questions

Is tap water in Vantaa safe to drink?

All the values shown here (18 September 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 Vantaa's drinking water?

At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 30 ng/L. The EU limit is 100 ng/L, so this water is under 30 % 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 Vantaa?

The water hardness in Vantaa is 0.6 mmol/L (soft). This mainly matters for household appliances and detergent dosing, not for health.

Where does this data come from?

All values come from official publications: Ruokavirasto (VATI) / Suomen ympäristökeskus Syke, Juomavesidirektiivi-rajapinta. Retrieved on 28 September 2026.

Lähde: Ruokavirasto (VATI) / Suomen ympäristökeskus Syke, Juomavesidirektiivi-rajapinta, CC BY 4.0, haettu 2026-09-28. Kunnassa on 6 vedenjakelualuetta VATI-rekisterissä; kaikki on lueteltu sivulla. Sivun PFAS-luku on alueelta "HSY:n vesihuolto" (uusin määritysrajan alle jäänyt PFAS-tulos 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.
