In India many people do not have the access to safe drinking water, what appears safe is just clear water. So what is safe drinking water according to you?
Water which looks clear may not always be clean and fit for drinking as it may have dissolved impurities, micro organisms and may even have odour. Water can be made fit for drinking by boiling it or by the chemical process of chlorination. If the water is not safe for drinking, it may lead to various water born diseases.
