Drinking water quality in Jouy-sur-Morin
PFAS in drinking water
The total of 20 PFAS ("forever chemicals") was last measured at 0.033 µg/L. The EU limit is 0.1 µg/L, so this water is at 33 % of the limit. (5 November 2025)
This source does not list each PFAS substance separately, so we cannot compare this water with the health limit.
For context: the total of all 20 PFAS (0.033 µg/L) is already above 0.020 µg/L, the limit Germany will enforce from 2028.
