Drinking water quality in Baie-Mahault
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at 0.001 µg/L. The EU limit is 0.1 µg/L, so this water is at 1 % of the limit. (8 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 Baie-Mahault safe to drink?
Yes. The latest official test (30 June 2026) checked the tap water in Baie-Mahault and it passed every requirement.
How high are PFAS levels in Baie-Mahault's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at 0.001 µg/L. The EU limit is 0.1 µg/L, so this water is at 1 % of the limit. (below the EU limit)
Does the water in Baie-Mahault 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 Baie-Mahault?
The water hardness in Baie-Mahault is 1.64 °f (soft). This mainly matters for household appliances and detergent dosing, not for health.
