5,681 Texas water systems have inventoried 9,403,091 service lines for EPA. 4,470 (<0.1%) are confirmed lead and 2,179,373 (23%) are still of unknown material. Below: every large or city-linked Texas utility ranked by lead lines.
Texas water systems reported 4,470 lead service lines and 112,525 galvanized lines requiring replacement as of Q2 2026 — <0.1% of the 9,403,091 lines inventoried and 0.2% of the national lead total, ranking #29 of 51. CITY OF TYLER reports the most in the state (142).
CITY OF TYLER (142), MCALLEN PUBLIC UTILITY (121), CITY OF SAN ANGELO (70) lead the list; 145 Texas 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 Texas city water reports.
