Is it ok to drink water in plastic bottles?

We do not recommend water that is packaged in plastic - even the hard polycarbonate plastic that is popular in 5-gallon jugs that can be taken home and used with a water stand. The reason for our recommendation is migration of plastic compounds, including BPA. Even at room temperature, a very small amount of the plastic in the water container will migrate into the water and increase certain health risks. In some cases, the degree of risk here is very, very small (although more and more concern has been given recently to the hormonal impact BPA may have, especially on children). Nevertheless, since we drink (or should be drinking) water every single day of every single year, any amount of risk here seems worth preventing. Even though glass containers are very inconvenient and more easily broken, we believe that the additional trouble here is worthwhile in terms of health.
