Regarding water, we have heard since childhood that water never spoils. But the question is whether closed bottled water expires? Because the expiry date is written on the water bottle. Today we will tell you when water gets spoiled and what experts say about it.
Expiry date of water?
Most of the people must have seen the expiry date of bottled water. According to a report, expiry date is written on bottled water. It is valid for 2 years beyond the packing date. However, scientists say that the plastic of the bottle slowly starts dissolving in water, hence after 2 years it becomes unfit for drinking. Actually, the expiry date on water bottles is not for the water but for the bottle. Because plastic bottles can break down over time and release chemicals into the water.
tap and river water
Water from taps and rivers never expires. Because it is a chemical compound. It consists of hydrogen and oxygen molecules, which do not change with time. Additionally, there are no living organisms in water, so it does not deteriorate over time. However, water may contain impurities, which can spoil over time. These impurities may include bacteria, viruses, and chemicals. But it is also true that water has antibacterial properties which prevent the growth of bacteria and viruses.
research report
According to the report of Word School of Public Research, tap water can be stored and used for 6 months. Because it never spoils. Only carbonated tap water is such that its taste gradually changes. Because the gas slowly comes out from it. Let us tell you that after the carbon dioxide present in the air mixes with water, it becomes slightly acidic. But if the containers are kept in a cool, dry and dark place for 6 months, the taste of water will never change.
How is water kept safe?
Let us tell you that one should avoid using pipes while filling water in containers. After filtering it should be filled directly from the tap. At the same time, it should be kept covered with a lid at all times to avoid contact with air. Another way to save water is to boil the water for about 15 minutes and then cool it.
