More about this result
PFAS-4 is not published for this supply area
Sum of 20 PFAS: 0.4 ng/L (0.0004 µg/L), 0.4 % of the 100 ng/L legal limit, sampled 11 May 2026.
Values from Talousveden jakelualue Heinolan vesihuoltolaitos, one of 2 supply areas serving Heinola; 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 Heinola safe to drink?
All the values shown here (15 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 Heinola's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.4 ng/L. The EU limit is 100 ng/L, so this water is at 0.4 % 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 Heinola?
The water hardness in Heinola is 0.9 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.

Sivun PFAS-luku on alueelta "Talousveden jakelualue Heinolan vesihuoltolaitos" (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.
