More about this result
PFAS-4 is not published for this supply area
Sum of 20 PFAS: 1 ng/L (0.001 µg/L), 1 % of the 100 ng/L legal limit, sampled 12 August 2025.
Values from Poikkilinjan vesiosuuskunta, one of 8 supply areas serving Ilmajoki; 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.

In Ilmajoki, the latest published PFAS-20 result is 1 ng/L (0.001 µg/L), below the EU legal limit of 100 ng/L, sampled 12 August 2025. 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.

Values to watch
These results are close to their legal limit, or over it.
One routine sample was outside a limit: Lead 11 µg/L on 12 August 2025 (limit ≤ 10 µg/L), Coliform bacteria 1 n/(100mL) on 12 August 2025 (limit ≤ 0 n/(100mL)), pH 6.2 on 12 August 2025 (limit 6.5–9.5 pH), Iron 440 µg/L on 9 September 2025 (limit ≤ 200 µg/L), Manganese 440 µg/L on 12 August 2025 (limit ≤ 50 µg/L), Aluminium 460 µg/L on 9 September 2025 (limit ≤ 200 µg/L). This is a single result, not an official verdict on the supply.

Frequently asked questions
Is tap water in Ilmajoki safe to drink?
The authorities have not published an overall verdict for this water. One routine sample was outside a limit: Lead 11 µg/L on 12 August 2025 (limit ≤ 10 µg/L), Coliform bacteria 1 n/(100mL) on 12 August 2025 (limit ≤ 0 n/(100mL)), pH 6.2 on 12 August 2025 (limit 6.5–9.5 pH), Iron 440 µg/L on 9 September 2025 (limit ≤ 200 µg/L), Manganese 440 µg/L on 12 August 2025 (limit ≤ 50 µg/L), Aluminium 460 µg/L on 9 September 2025 (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 Ilmajoki's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 1 ng/L. The EU limit is 100 ng/L, so this water is at 1 % 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 Ilmajoki?
The water hardness in Ilmajoki is 0.6 mmol/L (soft). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?

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.
