Not true! NYC does not have "famously good water". I found that out when I had to change my counter-top water filter after about one year of use.
It was more than gross. Imagine having to drink that water without the benefit of a water filter. By the way, I don't think water people drink in many restaurants are filtered.

Anyway, all water filters get very funky after a year.
That's how you tell what you'd have been drinking without filtration.
Wait until you find out what's in your food!
We don't have to imagine it. Plenty of people do.
Concentrate a year's worth of tiny impurities and you'll wind up a bit of sludge, yes. You'd probably get it even with pure distilled water from dust and microbes in the air.
Chances are you're breathing a lot more nasty in from taxi exhaust and human feces from farts than you're getting from that water.
With their quaint barrel-like contours and weathered
cedar-plank sides, rooftop water towers are a constant on
the New York City skyline. And though they may look like
relics of a past age, millions of residents get their
drinking water from the tanks every day.
But inside these rustic-looking vessels, there are often
thick layers of muddy sediment. Many have not been
cleaned or inspected in years. And regulations governing
water tanks are rarely enforced, an examination by The
New York Times shows.
I'm talking about the water that reaches my faucet, not the one somewhere upstate NY.
