Tap Water Or Bottled Water?

[a e l i]

Since my grandma was a microbiologist that worked for Moscow's aqueduct back in the Soviet Union days, my family has always thought tap water was the best. While it certainly is more eco-friendly than bottled water because of the lack of plastic, I'm starting to doubt the health benefits of tap water. After all, my grandma's knowledge may be outdated. Also, I'm always told about how dangerous chlorine and other chemicals are and I'm not sure if chemicals in tap water are unhealthy or not, since that may just be some kind of advertising/propaganda (here in Italy the vast majority drink bottled water).

Honestly, I wish tap water was healthier because of the environment, but wishful thinking won't lead me anywhere good. Anyway, I really have no idea what to believe!

So, where do you guys get your water? Why? If you drink tap water what do you have to say about the chemicals added to disinfect it?
