More about this result
No PFAS result is published for Siuntio in the data retrieved on 28 September 2026 (Ruokavirasto (VATI) / Suomen ympäristökeskus Syke, Juomavesidirektiivi-rajapinta). PFAS testing of drinking water has been mandatory across the EU since January 2026. The latest published check dates from 14 July 2026.
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.

Values to watch
These results are close to their legal limit, or over it.
One routine sample was outside a limit: Iron 220 µg/L on 14 July 2026 (limit ≤ 200 µg/L). This is a single result, not an official verdict on the supply.
| What was tested | Value | Limit | Status |

Frequently asked questions
Is tap water in Siuntio safe to drink?
The authorities have not published an overall verdict for this water. One routine sample was outside a limit: Iron 220 µg/L on 14 July 2026 (limit ≤ 200 µg/L). 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 Siuntio's drinking water?
No PFAS results have been published for Siuntio 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 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 Siuntio?
The water hardness in Siuntio is 0.5 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.

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.
