Best bottle water is Lauretana (from North Italy) and I've also heard of "Blackforest" bottle water should be also one of the safest one. Good luck finding the best solution. In the meanwhile you can boil tab water twice 10 minutes and pour away the water grounds. I don't recommend Evian... it's full of inorgnic minerals. If you buy water, I highly recommend buying water in glass bottles. As PET releases toxins such as pesticides, PFAS etc. into the water.✌🏻🍀
