New York has great tap water - no weird flavors or funny aftertaste. It's piped in from reservoirs more than 100 miles away upstate. I have a Brita pitcher in my fridge but the filter is truly unnecessary, which is good because I often forget to refill it so I drink straight tap water most of the time.
Virginia has horrendously chlorinated nastiness coming out of the tap. Not to mention traces of medicines, lead, and who knows what else. It tastes like a swimming pool. Carbon filters do help with this, but now (or in 4 weeks) may be a good time to look into that home water cooler I've always wanted.
