Good for you, but this is what the International Association for Medical Assistance to Travellers has to say about Italy:<p>&gt; <i>Drinking water is chlorinated and has no ill effect on the local population. However, some strains of e. coli (naturally occurring bacteria found in your gastro-intestinal system) may be present in very small concentrations in the local water supply. Some local strains are different than those that you may be used to, and may cause diarrhea in travellers since immunity is not developed as a result of short-term exposure. Using bottled water for the first few weeks will help you adjust and decrease the chance of traveller&#x27;s diarrhea.</i><p><a href="https:&#x2F;&#x2F;www.iamat.org&#x2F;country&#x2F;italy&#x2F;risk&#x2F;food-water-safety-overview" rel="nofollow">https:&#x2F;&#x2F;www.iamat.org&#x2F;country&#x2F;italy&#x2F;risk&#x2F;food-water-safety-o...</a><p>Poking around, the same warning is in place for Spain and Portugal.<p>I always get bottled water when travelling, although I tend to get the cheap local or store brand water. A few euros is really cheap anti-diarrhea insurance, and it tastes a lot better than chlorinated water, too.
