New York water systems reported 251,269 lead service lines and 37,819 galvanized lines requiring replacement as of Q2 2026 — 6.6% of the 3,811,676 lines inventoried and 11% of the national lead total, ranking #3 of 51. NEW YORK CITY SYSTEM reports the most in the state (120,931).
NEW YORK CITY SYSTEM (120,931), BUFFALO WATER AUTHORITY (34,208), SYRACUSE CITY (17,239) lead the list; 229 New York systems report at least one lead line in total.
Find your utility in the table below, then check its published service line inventory (most utilities post an address-lookup map) or call the number on your water bill. Utilities must notify customers whose line is lead, galvanized-requiring-replacement or unknown. You can also test the pipe entering your home: lead is soft, dull gray, non-magnetic and turns shiny when scratched.
Under EPA's Lead and Copper Rule Improvements, systems must replace lead and galvanized-requiring-replacement lines within 10 years starting in 2027; systems with very high counts can receive longer deadlines. Ask your utility for its replacement plan and whether it covers the homeowner-owned portion.
Use a filter certified to NSF/ANSI 53 for lead for drinking and cooking, flush the tap after water has sat for hours, never use hot tap water for drinking or infant formula, and confirm your actual level with a certified lab test.

A certified mail-in lab test shows exactly what's in your water — lead plus dozens of other contaminants — with EPA-grade accuracy. Know your real levels before spending on a filter.

A lead or unknown service line means lead can enter water after it leaves the treatment plant, so city-level test results understate what reaches your tap. Filter drinking and cooking water with an NSF/ANSI 53 lead-certified system, and see the lead in drinking water guide or New York city water reports.
