Over priced and 100% unnecessary, unless you live in Flint

That is 100% untrue, even the flint water could be treated to be potable.

In your home? If you knew the water was that contaminated would you trust your home water treatment equipment to remove everything? In that situation I think I'd buy bottled water until things are resolved.

Distilling water with an activated carbon filter does remove everything.

Sure, how much does that system cost and does it actually taste good to drink? I've heard distilled water tastes horrible.

if you remove everything from the water with this method, or any other method, there is systems to re-mineralize water... (Reverse osmosis would also remove most of the lead)

I'm sure even bottled water isn't prone to pollution, but more and more alarms are raised about medical pollution in tap water. So I'm still happier when I drink out of a bottle.

you might be happier, but that's just your emotions playing with you, no rationality. I see it all the times with colleagues - they have amazing tap water coming straight from Alps (it really tastes well) and 2 metres next to it vending machine with 2 euro per 0.5l plastic bottle. Well guess what they do every single effin' time...

most of bottled water is tap water in plastic bottles, potentially infused with mix of BPA and other if ever exposed to slight amount of sunlight. don't ever think they use some high quality inert plastics on that bottle, because they don't.

with true deep well/mountain spring you are getting potentially better quality prior to bottling, and no idea what in final bottle.

if you have really poor quality tap water where you live, that's your best choice. it still might not be a healthy choice though.

My city's water comes from deep aquifers. In theory it is high quality, but in practice it tastes horrible because it is so hard.

My city just kicked off a project to deepen the wells so they don't need as much anti-bacterial treatment and the savings will be used to soften it a bit.

I once went to the town of Evian and saw people ordering bottles of Volvic in the restaurants...

Plus there's nothing wrong with buying a washable travel mug and just filling it with tap water.
