Lead Service Lines in Lexington, KY

What you need to know

Lexington's water is delivered by six systems, with Kentucky-American Water Co. serving the vast majority of the 672,225 residents. The good news: no confirmed lead service lines have been identified in Lexington's public water systems so far.

But "not yet found" doesn't mean "not there." Lead service lines—pipes that carry water from the main water line to your home—are often hidden underground. Many utilities across the country are still in the early stages of mapping them. Lexington's utilities have not reported data on how many lines they've inspected or what percentage of their inventory remains unknown.

Why this matters

Lead in drinking water is a real health concern, especially for children and pregnant people. It leaches into water when it corrodes old pipes and solder. Even small amounts matter. If you live in a home built before 1980, there's a higher chance your service line contains lead—though homes built after that date aren't automatically safe.

What Lexington utilities are doing

Kentucky-American Water Co. serves about 669,000 Lexington residents. The utility is required by federal law to maintain an inventory of service line materials and report findings to regulators. You can request your home's service line information directly from the utility—that's often the fastest way to get answers specific to your address.

The smaller systems serving Lexington (Eastern Rockcastle, Millersburg, and three very small operations) follow the same federal requirements, though their inventories may be less complete.

What you can do right now

Even without a confirmed lead service line, simple steps reduce risk. Use cold water for drinking and cooking (hot water leaches lead faster). If your tap hasn't been used for several hours, run it for 30 seconds before filling a glass. If you're concerned about your water, an inexpensive test kit can check for lead; the EPA maintains a list of certified labs.

Next steps for residents

  • Contact your water utility directly and ask about your home's service line material. Have your address ready.
  • Request a free or low-cost lead test kit from your utility or local health department.
  • If you rent, ask your landlord for service line records.
  • Visit the EPA's lead in water page for testing and treatment options.

Common questions

Does Lexington Kentucky have lead in the water?

No confirmed lead service lines have been identified in Lexington's public water systems. However, utilities are still mapping their inventories, so unknown lines may exist. The best way to know your home's status is to contact your water utility and ask about your specific address.

How do I find out if my house has a lead service line?

Contact Kentucky-American Water Co. or your local water utility with your address—they're required to have service line records. You can also hire a plumber to inspect the line where it enters your home, or check your home's original construction documents if available.

Is it safe to drink tap water in Lexington?

Lexington's tap water meets federal safety standards. If you're concerned about lead specifically, you can request a test kit from your utility or have your water tested by a certified lab. Boiling does not remove lead, but filtration systems labeled NSF/ANSI 53 can reduce it.

What should I do if my home has a lead service line?

Contact your utility to learn about replacement programs—some offer cost-sharing or rebates. In the meantime, use cold water for drinking and cooking, flush the tap if it hasn't been used for hours, and consider a certified lead-reducing filter. Talk to your pediatrician or doctor if you have health concerns.
