Our water source is some of the best in the country, Scituate reservoir. Problem is that providence is one of the oldest cities in the union so we also have alot of old pipes even though they still function. Now include all those deposits from old pipes with the added govt mandated chlorine you get nasty tap water.

Best bet is to get a filter. Either a jug or a filter directly on the faucet. You could also install a more permanent setup under the faucet.
