Drinking water quality in Vernon

Q: Is tap water in Vernon safe to drink?

Yes. The latest official test (10 June 2026) checked the tap water in Vernon and it passed every requirement.

Q: How hard is the water in Vernon?

The water hardness in Vernon is 32.7 °f (hard). This mainly matters for household appliances and detergent dosing, not for health.

Q: Where does this data come from?

PFAS in drinking water

EU legal limit

0.0252 µg/L Limit: 0.1 µg/L within limit

The total of 20 PFAS ("forever chemicals") was last measured at 0.0252 µg/L. The EU limit is 0.1 µg/L, so this water is at 25 % of the limit. (12 March 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 (0.0252 µg/L) is already above 0.020 µg/L, the limit Germany will enforce from 2028.
