Drinking water quality in La Wantzenau
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at 0.014 µg/L. The EU limit is 0.1 µg/L, so this water is at 14 % of the limit. (16 September 2025)
The four most harmful PFAS add up to 0.014 µg/L. That is 3.5 times the health limit of 0.004 µg/L that Sweden made law in 2026. Germany will set a similar limit in 2028.
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 La Wantzenau safe to drink?
Yes. The latest official test (29 June 2026) checked the tap water in La Wantzenau and it passed every requirement.
How high are PFAS levels in La Wantzenau's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.014 µg/L. The EU limit is 0.1 µg/L, so this water is at 14 % of the limit. (below the EU limit)
Does the water in La Wantzenau also meet the strictest limits in Europe?
No. The four most harmful PFAS add up to 0.014 µg/L. That is 3.5 times the health limit of 0.004 µg/L that Sweden made law in 2026. The water still passes the current EU limit (0.1 µg/L for the total of 20 PFAS).
How hard is the water in La Wantzenau?
The water hardness in La Wantzenau is 20 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
