I hate the taste of the tap water in my apartment, what can I do?

I don't mind cooking it, and I've been told to drink more water, but I hate the taste of it. But I don't want to piss off the environmentalists by drinking bottled water. The only way I'll drink more water and less pop is by bottled water. Should I invest in a water cooler and those 3 gallon water jug thingys I see at the supermarket where you can buy bottled water in a refillable water jug thingy? Thanks!
