Drinking water quality in Chars
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at <0,0290 µg/L. The EU limit is 0.1 µg/L, so this water is at 0 % of the limit. (14 November 2025)
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 Chars safe to drink?
All the values shown here (29 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 Chars's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at <0,0290 µg/L. The EU limit is 0.1 µg/L, so this water is at 0 % of the limit. (below the EU limit)
Does the water in Chars 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 Chars?
The water hardness in Chars is 23.23 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
