In the United States, it is a little bit different.
There are “standards” that water quality has to live up to. Do these standards actually meet the criteria for safe drinkable tap water? Not always. This is evident in places like Flint, Michigan and other poorer urban areas.
Some of the tap water can be so bad that people wouldn’t dare to drink it even after boiling.
In some areas, the tap water quality is wonderful.
Here is a relatively decent source about the topic as it pertains to the USA. https://wisevoter.com/state-rankings/best-tap-water-in-the-us/#:~:text=The ten states with the,%2C South Dakota%2C and Nevada.
The long story short here, is certain places like Hawaii have extremely clean tap. Other places, like Texas, are notorious for having numerous water quality violations.
It falls down to each individual State and City for maintaining the standards that were set. In my opinion, it it just an easy way for them to waive liability at the end of the day.
