Hi again, Kathleen!
I believe there's a thread on this topic here on the message board so try a SEARCH.
But in short, you'll find that water in the cities on the Iberian Peninsula is quite safe for "American" stomachs. I've never had problems. In fact, water treatment plant standards in the cities are typically higher than those in the USA. Places in the countryside, however, may be a different case although it's rather hit-and-miss. I've never had any "stomach issues" after visiting any of Spain's smallest villages but different stomachs can handle different microbes, of course.
Anyone else have feedback on this topic? Saludos, MadridMan
