Drinking water quality in Plouhinec
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at 0.0054 µg/L. The EU limit is 0.1 µg/L, so this water is at 5 % of the limit. (4 May 2026)
The four most harmful PFAS add up to 0.0013 µg/L, below the health limit of 0.004 µg/L used in Sweden since 2026.
One of these four, PFOA, is classified as causing cancer in humans by the WHO's cancer research agency (IARC).
Substances too small to measure count as 0, so the real total may be higher.

Frequently asked questions
Is tap water in Plouhinec safe to drink?
Yes. The latest official test (4 June 2026) checked the tap water in Plouhinec and it passed every requirement.
How high are PFAS levels in Plouhinec's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.0054 µg/L. The EU limit is 0.1 µg/L, so this water is at 5 % of the limit. (below the EU limit)
Does the water in Plouhinec 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 0.0013 µg/L stays below.
How hard is the water in Plouhinec?
The water hardness in Plouhinec is 10.7 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
