This question is obviously intended for those that live in places where tap water is “safe to drink.”
I live in Southern California, where I’m at the end of a long chain of cities. Occasionally, the tap smells of sulfur, hardness changes, or it tastes… odd. I’m curious about the perspective of people that are directly involved and their reasoning.
Scotland and North-West England have excellent tap water. The water in the Midlands and London is perfectly safe to drink, but it certainly has a taste to it.
If you wish to taste some Finnish ones, I’m sure I can bottle and ship some of our tapwater for you guys to taste.

Severn Trent (the midlands) is often voted the best tap water in the UK.
