You have mentioned a lot of harmful effect re: use of plastic bottle for storing water, but NOT suggested what alternative pack one can use! So far my knowledge goes, one plastic, the plymer of ethylene (called polythelene), is an inert product, and does not react so quicklyhence, it says, water can be stored for a few days. Also, Drug Controller in our country, or say, FDA in USA, freely allow even aerated waters like Coca Cola etc to store and sell in plastic bottle world over. Can you pl clarify your recommendation in light of that?
