Drinking water quality in Retiers
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at 0.0017 µg/L. The EU limit is 0.1 µg/L, so this water is at 2 % of the limit. (7 April 2026)
The four most harmful PFAS add up to 0 µg/L, below the health limit of 0.004 µg/L used in Sweden since 2026.
Substances too small to measure count as 0, so the real total may be higher.

Frequently asked questions
Is tap water in Retiers safe to drink?
All the values shown here (7 April 2026) are within the legal limits, but the authorities have not published an overall verdict for this water.
How high are PFAS levels in Retiers's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.0017 µg/L. The EU limit is 0.1 µg/L, so this water is at 2 % of the limit. (below the EU limit)
Does the water in Retiers also meet the strictest limits in Europe?
Yes. Even against Europe's strictest limit, the health limit of 0.004 µg/L used in Sweden since 2026, the measured value of 0 µg/L stays below.
How hard is the water in Retiers?
The water hardness in Retiers is 17 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
Where does this data come from?
