We have well water at home, and I have no problem drinking that. We do have a filter on the fridge water dispenser, simply because it came on the fridge and we have one of those water filters attached to the faucet, but I don't actually flip it to filter when getting the water out of the tap. I LIKE our water.
School is a different story. The town my college is in has HORRIBLE water. You can smell the chlorine in it. It tastes disgusting (not to mention destroys my hair...). So I buy cases of Poland Springs water for here
