I grew up in New York City, and my rule has always been...let it run cold out of the tap, then drink away. It's great water. The only concern can be your pipes. So if it tastes good, use it. If not, slap a water filter on your faucet and try that. I'm in DC now, and I brew with water from a filter on my faucet with great results.
Some recipes, and some all-grain brewing situations, call for specific water conditions. If that is a concern for you, then get a water composition report from the city. But again, pipes in NY are in some cases 100 years old. So I'd settle on, if it tastes, good, use it.
