Drinking water quality in Paris

Q: Is tap water in Paris safe to drink?

Yes. The latest official test (30 April 2026) checked the tap water in Paris and it passed every requirement.

Q: How hard is the water in Paris?

The water hardness in Paris is 24.92 °f (medium). This mainly matters for household appliances and detergent dosing, not for health.

Q: Where does this data come from?

All values come from official publications: Hub'eau, Qualité de l'eau potable (Ministère de la Santé / OFB / BRGM). Retrieved on 28 August 2026.

PFAS in drinking water

EU legal limit

0.002 µg/L Limit: 0.1 µg/L within limit

The total of 20 PFAS ("forever chemicals") was last measured at 0.002 µg/L. The EU limit is 0.1 µg/L, so this water is at 2 % of the limit. (15 April 2026)

This source does not list each PFAS substance separately, so we cannot compare this water with the health limit.

Official assessment
