I'm amazed we don't hear about bottled water causing more problems. Oh we do, for example one of the international Coke companies managed to make Belgium bottled water with a bit of bleach a few years back.

Not sure manure is the concern about fruit, probably more the pesticide, herbicides and hormones (mainly a US problem)that you get on them.

I generally trust well run tap water, but if I get a gypy tummy then its bottled water wherever I am

Still in Spain you don't want to drink water, that is what the wine is for

Oh I wouldn't go near tap water in Barcelona...in fact anywhere in Spain...in fact anywhere in Europe. Cholera is still rife and bubonic plague can't be ruled out
