Drinking water quality in La Léchère
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. (11 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.

Frequently asked questions
Is tap water in La Léchère safe to drink?
Yes. The latest official test (30 June 2026) checked the tap water in La Léchère and it passed every requirement.
How high are PFAS levels in La Léchère's 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. (below the EU limit)
Does the water in La Léchère 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 La Léchère?
The water hardness in La Léchère is 10.3 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
