Since 2000, United Nations Committee on economic, social and cultural rights elaborated the necessity of drinking water and included this as a person’s right. Kofi Annan, former United Nations Secretary General, declared access to safe water as the fundamental human need and a basic human right. Different types of storage vessels are used for storing water, plastic bottles being one of them.
Is Water stored in plastic bottles, safe?
Michael Moore, Emeritus Professor of Toxicology at the University of Queensland says that water stored in plastic bottles is safe, but it depends on the kind of plastic the bottle is made of. Finding the best bottles for storing water is essential in keeping your water safe for future use. According to the National Resources Defense Council (NRCD), there is potential health dangers of the chemical bisphenol-A (BPA) used in certain types of polycarbonate plastic water bottles.
The ‘single use’ bottles are usually made from polyethylene terephthalate (PET), an inexpensive and lightweight plastic. Some plastics then have chemicals added to give them characteristics such as flexibility or colour. BPA hardens plastics and as the plastic breaks down over time, BPA is released into the water held in polycarbonate bottles, mainly when the bottle is heated or repeatedly washed. This has been linked to increased risks of diabetes, heart disease, early onset of puberty in children, erectile dysfunction and infertility.
The NRDC suggests avoiding plastic bottles with the number 3, 6, or 7 on the bottom; the best bottles to use and reuse are those with the recycling codes 2, 4 and 5.
The best bottles to store water:
-Copper Bottles: According to Ayurveda water stored in a copper vessel has many health benefits. The water in copper bottles can be stored for long periods of time.
-Lined Aluminum Bottles: Aluminum bottles are safer than plastics for storing water. If you choose an aluminum bottle, find one that is lined with a water-based, non-toxic lining.
-Stainless Steel Bottles: Using stainless steel bottles decreases the risk of ingesting potentially harmful chemicals which may leech from the walls of some plastic bottles over time. Also stainless steel bottles are very durable
-Glass Bottles: One of the best bottles for storing water is a glass bottle, according to U.S. News, World Report and the NRDC. Glass is a safe material for storing water because it is free of potentially harmful chemicals.
