The important distinction
A city report is not the same thing as your faucet.
This page should help a visitor separate the quality of the protected municipal supply from what can happen inside an older building.
NYC DEP reports on the citywide supply, but individual building plumbing can still affect lead or taste at the tap.
What to check first
The practical water-quality read for New York
Annual water report

Where New York's drinking-water picture starts

For renters, travelers, and Airbnb guests
A fast checklist before you trust the tap
Read the latest DEP water report first, then ask the host or building manager about plumbing age and lead testing.
If the apartment is in an older building, flush cold water before drinking and consider certified filtration for lead-sensitive households.
Check whether building maintenance, tanks, or internal pipes could be causing taste, odor, or discoloration.
Report persistent discoloration, metallic taste, or sediment instead of relying on a citywide water reputation.
