I know NYC doesn't treat their water at all…
EDIT: I'm a dork an grabbed the wrong URL. Changed URL to a PDF for lack of better.
A major metro doesn’t treat its tap water? Where on earth did you get that crazy idea?

I'll save some digging: "Even without filtration, the water is carefully treated to reduce the risk of harmful microorganisms."
You linked to wastewater treatment, not drinking water. Wastewater is definitely treated in NYC.
Tap water is treated (UV and chloride disinfecting), but is largely not filtered: https://en.wikipedia.org/wiki/New_York_City_water_supply_sys...
He was talking about the drinking water that comes from the faucet, not the sewage.
The untreated NYC water has tiny crustaceans in it, which make it not Kosher, which is why thee bagels from a Jewish deli in NYC are so good. Go figure.

Thanks for the correction, I should have looked harder at that page before posting. I've since corrected.
There's no way the water is untreated. Like just about everywhere else on earth, they will add chlorine when necessary.
