Why Not Reuse Water Bottles

There are many types of water bottles and it pays to know which ones can be reused. A bottle labeled 1 is only safe for a single use. When exposed to oxygen or high temperatures, including sun heat, such a bottle will discharge toxic substances that get into the water. Also avoid bottles labeled 3, 6, or 7 as they exude toxic chemicals able to penetrate drinks, and lengthy exposure can result in severe health problems.

Bottles made of polyethylene (2 and 4) and polypropylene (5) are suitable for multiple uses. They are relatively safe if you only store cold water in them and regularly disinfect them.
