Drank tap water in Slovakia, Hungary, Romania, Bulgaria, Croatia, Turkey, China, Egypt, Sri Lanka even the US and I am still here. I think it's more that you can't automatically assume if it comes out of tap it's safe. I was in Bulgaria this year and looked into it: there were like three villages with not safe water in the whole country. A lot better than the lead problem in the US. Ask people around, google and smell the water. It's probably fine.
