Problem Of Boiled Water
- Boiling cannot remove harmful heavy metals and pesticides in drinking water. Water supplied in Dhaka is taken from Buriganga or groundwater for treatment and the water of these sources have high level of harmful contents because of disposal of factory wastes in river and heavy use of chemical pesticides. Government treatment facilities do not remove these harmful contents.
- Boiling of water for long can destroy bacteria & viruses but it fails to remove dissolved impurities like rust, arsenic, and harmful salts. The logic is simple! Even if you mix sugar or salt in water and boil it, the water will remain sweet or salty. Dissolved impurities in boiled water can affect your health.
- Certain elements (eg nitrate, lead etc) usually found in the tap water increases their concentration during the time of boiling and make the boiled water even more unsafe to drink. In certain temperature germs might die but the residues remain in the water.
