This depends on quality of water supply. Water is safe in many cities. Peole do not use tapped water for drinking at Agra. Most people have submersible pumps for drawing ground water for muptiple uses. They buy mineral water for drinking.
Yes, you are right and I have read some where that drinking water contains enough bacteria to infect us and therefore it is always advisable to use a filter or add some medicine to disinfect it. I have even heard doctors advising to boil the water before using it for drinking purpose!!!
tap water is safe for drinking only in clean areas as well as if the person who takes care of distribution process how he manages the cleanliness of water.
Drinking tap water will make a person go mad due to increase in salts in water which effects the nervous system.when we drink pure water, it cleanses our system
Tap water should not be use in daily use for drinking. You never know what that water contains. Such water will be full of bacteria and viruses. Before purifying we should not take such water for drinking purpose.
Now it is beyond any doubt that tap water contains harmful dissolved impurities and we should make sure to disinfect it properly before consuming them....
tap water is not 100% safe yet in my home all of use tap water directly even i know we should purify it . but there is no problem as the tap water here is too clear to use.
Unfortunate thing is that pipelines can get damaged if not maintained by Municpal authorites, Hence sometimes even drainage water is mixed, which happens often. It is better to drink purified water.
