Drinking water quality in Vailly-sur-Aisne
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at <0,029 µg/L. The EU limit is 0.1 µg/L, so this water is at 0 % of the limit. (5 June 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.
