Here is what to know about bottled water:
- Bottled water can have an expiration date, though it's legal in the US to sell expired water.
- Bottled water's expiration date warns when leached chemicals will begin to affect the water's taste mostly because they bottle itself starts to deteriorate, shedding microscopic chemicals into it.
- These compounds may make your water taste like medicine, chlorine, or ozone.
- Drinking expired water probably won't harm you, especially if the water was stored properly.
