Drinking water quality in Montauban
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at <0,044 µg/L. The EU limit is 0.1 µg/L, so this water is at 0 % of the limit. (14 January 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 Montauban safe to drink?
Yes. The latest official test (30 June 2026) checked the tap water in Montauban and it passed every requirement.
How high are PFAS levels in Montauban's drinking water?
The total of 20 PFAS ("forever chemicals") was last measured at <0,044 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 Montauban 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 Montauban?
The water hardness in Montauban is 19.7 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.
