I have always used either filtered or bottled water for my baking.
All bakeries I have worked at use filtered water.
The chlorine and chloramine in tap water are not good for natural yeast and will kill it. Not that good for drinking either.
I used to keep fish some 20-30 years ago.
The process back then to top up your aquarium, was to fill a bucket with tap water, and leave it for 24 hour for the chlorine to evaporate.
This changed with the introduction of chloramine and you now need specialist chemicals to remove the chloramine.
The introduction of chloramine into our tap water here in the UK came about 30 years or so ago, when a London hospital was overwhelemed with its patients dying of water bourne diseases.
Initially they could not work out what was causing it. They eventually found that the culprit was the water storage tank on the roof of the Hospital that supplied its water. The stagnant water had developed all sorts of bacteria and viruses.
So they introduced chloramine.
Generally though, I do not trust any privatised water company here in the UK. They are more concerned with profits than providing clean water.
I personally have a black staining sludge forming in my toilet cistern and in the outlet of my taps. It is not clean water.
So I always only use filtered water for everything.
