I live in Davao City, in the Philippines. It is considered "third world". Yet, it has one of the best water supply systems in the world. I drink it daily with never an ill effect. I can not say that for everywhere I have been.
The Davao City Water District (DCWD), among the first water districts to be established in the country since the promulgation of PD 198, as amended also known as the Local Water Utilities Act of 1973, ranked number one in the listing of the top 50 water utilities in the Asia-Pacific region in the Asian Development Bank's Second Water Utilities Data Book published in 1997, It shared top ranking with the water utilities of Singapore and Johor Bahru of Malaysia.
