PFAS in Saue vald's tap water: under 4 ng/L, none of the four main PFAS detected
Last PFAS check: · Source: Terviseamet
PFAS in drinking water
No PFAS detected
The lab sees nothing below 4 ng/L, 8 times our benchmark of 0.5 ng/L. Water above our benchmark would pass this check unnoticed.
0.5 ng/L is our benchmark, not an official limit. Same EFSA method as Sweden, Denmark and the Netherlands, but stricter. It's a yearly average, compared here with the latest check.
More about this result
The US also limits PFOA and PFOS to 4 ng/L each, per substance.
The lab detects each of the four substances from 1 ng/L upward. None reached that limit, so their total is below 4 ng/L rather than zero.

Frequently asked questions
Is tap water in Saue vald safe to drink?
Yes. At the check on 4 August 2026, the tap water in Saue vald was within every limit tested. “vastab nõuetele”
How high are PFAS levels in Saue vald's drinking water?
At the latest check the total of 20 PFAS ("forever chemicals") was below the laboratory's reporting limit of 1 ng/L. The EU limit is 100 ng/L, so this water is under 1 % of the limit. (below the EU limit)
Does the water in Saue vald also meet the strictest limits in Europe?
As far as this check can tell, yes. None of the four compounds was quantified, so their total is below 4 ng/L, the sum of the laboratory's detection limits, and under Sweden's legal limit of 4 ng/L in force since 2026.
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 Saue vald?
No hardness value is available for Saue vald in this source.
