PFAS in drinking water
PFAS compounds at the reporting limit (1–100 ng/L), no sum of 20 published
PFAS-4 not published here yet
More about this result
PFAS-4 is not published for this supply area
PFAS compounds reported at the laboratory's reporting limit (1–100 ng/L), too coarse to check against the 4 ng/L health benchmark; no sum of 20 PFAS was published (sampled 27 October 2025).
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.
17 of 78 municipalities have itemised PFAS results, all at the laboratory's reporting limit.
9 PFAS (see each substance)

| Perfluorobutaanhape (PFBA) | <0.001 µg/L |
| Perfluorobutaansulfoonhape (PFBS) | <0.001 µg/L |
| Perfluoroheksaanhape (PFHxA) | <0.1 µg/L |
| Perfluoroheksaansulfoonhape (PFHxS) | <0.1 µg/L |

Frequently asked questions
Is tap water in Saaremaa vald safe to drink?
Yes. At the check on 25 August 2026, the tap water in Saaremaa vald was within every limit tested. “vastab nõuetele” 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 Saaremaa vald's drinking water?
No PFAS results have been published for Saaremaa vald 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 Estonia?
Estonia transposes the EU Drinking Water Directive in regulation no. 61 of the Minister of Social Affairs (sotsiaalministri määrus nr 61): "PFASide summa" (sum of 20 PFAS) at most 0.10 µg/l, that is 100 ng/L. There is no national PFAS-4 limit; the health reference is EFSA's 4 ng/L. This site's 0.5 ng/L benchmark is stricter than both.
How hard is the water in Saaremaa vald?
No hardness value is available for Saaremaa vald in this source.
Where does this data come from?
All values come from official publications: Terviseamet, veeterviseohutuse infosüsteem (VTI) avaandmed, veevargi_veeproovid_2026.xml. Retrieved on 19 September 2026.
