Drinking water quality in Roura
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at <0,30 µg/L. The EU limit is 0.1 µg/L, so this water is at 0 % of the limit. (13 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 Roura safe to drink?
The latest official test failed at least one quality requirement.
How high are PFAS levels in Roura's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at <0,30 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 Roura 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 Roura?
The water hardness in Roura is 2.3 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
