Is bottled water better than tap?

There are two types of bottled water, spring water and mineral water. Spring water is collected directly from the spring and mineral water emerges from under the ground where it has flowed over rocks and is therefore high in mineral content. Spring water must be treated to meet limits set by pollution and mineral water can only be treated to remove grit and dirt.

So is it actually necessary to buy bottled water? In the end it comes down to personal taste, cost and convenience. There are no proven health benefits of bottled water and some may argue that the environmental damage the plastic bottle cause are reason to switch back to tap.
