Drinking water quality in Lussac-les-Châteaux
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at 0.0136 µg/L. The EU limit is 0.1 µg/L, so this water is at 14 % of the limit. (26 May 2026)
The four most harmful PFAS add up to 0.0024 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.
