According to a new study, a glass of drinking water contains around 10 million bacteria. That are not bad but they are good bacteria. The study claimed that so far knowledge about them has been practically non- existent.
A glass of clean drinking water contains ten million bacteria. According to researchers the tap water always contains less harmful bacteria.
They further added that good bacteria can keep the water clean and keep it safe. Similarly that happens in our body. Our intestines are full of bacteria that help us to digest food.
