In any case, do not worry; Vietnamese people too, get sick with unsanitary water!!! Water is thus automatically filtered and no need to worry if someone offers you a fresh glass of water with a few ice cubes floating! The ice cubes too are made with sanitary water! The only risk regarding water in Viet Nam involves the intake of fresh, washed and raw vegetables. However, this happens very rarely…
Are there any risks regarding water ?
It is still highly recommended not to drink tap water in Viet Nam, either in the city or the countryside. However, a lot of shops do sell bottles of water and refreshments at every street corner.
