Raleigh water seems fine, its generally clear, tasteless, and comes out most of the time I turn a facet on, so I'm hooked on it!
But in all seriousness, one just has to visit Falls Lake to see the basis for the Raleigh water. Hop on up to the boat ramp on Six Forks road on a weekend and watch the countless boats, jet skis, etc being launched and look at the water quality around the boat launch then you can decide how good the water is. I always have to wipe my boat down after coming out of Falls Lake due to the film of oil and whatever on top of the lake.
I have a well and a whole house filter and it does turn brown rather quickly due to the sediment in the well so no water is perfect!
But water taste and quality is relative and my relatives say its A-OK!
