 The Additional Risk of Plastic Bottles

Even if the water you choose is genuinely pure and health-friendly, the plastic bottle it's been packaged in and the length of time it is stored before it is consumed can dramatically change its “purity.” Water languishes in a plastic bottle at the manufacturer, at the warehouse, at the distributor and at the retailer that leaves ample time to leech out components from the plastic containers. This is a real concern. 

Also, water bottles that are reused may become home to a wide range of bacteria that can cause symptoms including stomach aches, vomiting, and diarrhea.
