PFAS in drinking water
<30 % of the EU legal limit for 20 PFAS
PFAS-4 not published here yet
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 18 February 2026.
Values from Päntäneen Vesihuolto Oy, one of 6 supply areas serving Kauhajoki; 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 Kauhajoki, the latest published PFAS-20 result is below the laboratory's reporting limit (<30 ng/L), sampled 18 February 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.

What the latest check found
The authorities have not published an overall verdict for this water.
Values to watch
These results are close to their legal limit, or over it.
One routine sample was outside a limit: Copper 6.5 mg/L on 19 February 2026 (limit ≤ 2 mg/L). This is a single result, not an official verdict on the supply.
| What was tested | Value | Limit | Status |
|---|---|---|---|
| Copper | 6.5 mg/L | ≤ 2 mg/L | over the limit |
| Nickel | 16 µg/L | ≤ 20 µg/L | within the limit |

Frequently asked questions
Is tap water in Kauhajoki safe to drink?
The authorities have not published an overall verdict for this water. One routine sample was outside a limit: Copper 6.5 mg/L on 19 February 2026 (limit ≤ 2 mg/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 Kauhajoki'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 Kauhajoki?
No hardness value is available for Kauhajoki in this source.

Sivun PFAS-luku on alueelta "Päntäneen Vesihuolto Oy" (uusin määritysrajan alle jäänyt PFAS-tulos kunnan 1 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.
