Don't make fun of bottled water guys O_o
It's totally worth it, look at it this way, tap water is reliant upon current environment to not change and ruin the water quality. While bottled water, that quality is staying there somewhat and not vulnerable to environment changes unless you smash the bottle.
For example, you recieve water from that river, and there's a oil spill, all of suddenly your tap water is undrinkable but bottled water is safe still.
Okay, why would there ever be a random oil spill in a river?
Some of you people are a little skeptical of the filtration process of water plants. Like I said, if you're that paranoid get your cities water quality report, or sometimes simply referred to as CCR. It will show all the chemicals that are present in your water and the MCL (the maximum amount of contamination considered for safe drinking water.)
As a rule of thumb, you want to know what the level of Lead (ppb) of you water is, your Nitrate and Nitride levels, the level of E.Coli present (should be 0% or simply not listed), and know the level of Arsenic, Mercury and Cyanide in you water (preferably none, but minute amounts are still considered safe.)
People really only need to worry about personal filtration systems if their household pipes are in bad shape/contaminated or if you don't get your water from a municipal source.
