Lead Service Lines in Arizona

Arizona serves about 7.3 million people through 1,676 water systems. Lead service lines—the pipes that connect the water main to individual homes—are a potential source of lead contamination if present and corrosion control isn't managed properly.

What we know about lead lines in Arizona

Arizona water utilities have not reported any confirmed lead service lines in their current inventories. This is good news, but it's important to understand what it means and doesn't mean.

Water systems are required by federal law to identify and track lead service lines. However, many systems—especially smaller utilities—are still in the process of completing their inventories. Some may not have received funding to conduct the surveys needed to find lead lines, or their records may be incomplete. A zero count doesn't necessarily mean lead lines don't exist; it may mean they haven't been found or reported yet.

Why this matters for your home

Lead enters drinking water primarily through old lead service lines or lead-containing plumbing fixtures. Even small amounts can pose health risks, especially for young children and pregnant people.

If your home was built before 1986 (when lead solder was banned in most new plumbing), your service line could be lead or galvanized steel, which can also leach lead. The only way to know is to have your utility check their records or have a plumber inspect the line at your property.

Your water utility can help

Contact your local water system directly. Ask:

  • Does your home have a lead service line or lead-containing plumbing?
  • What is your system's corrosion control strategy?
  • Can you test your tap water for lead?

Most utilities offer free or low-cost water testing. Results typically come back within a few weeks.

Next steps for residents

  • Contact your water utility to ask if your service line has been inventoried and what material it is made from.
  • Request a free water test if your home was built before 1986 or if you're concerned about lead.
  • Speak with a pediatrician if you have questions about health impacts; visit the CDC's lead and health information for guidance.
  • Run your tap water for 30 seconds before drinking or cooking if you haven't used it in several hours—this flushes water sitting in pipes overnight.

Frequently asked about lead pipes in Arizona

Does Arizona have lead in the water?

Arizona water systems have not reported confirmed lead service lines in their inventories. However, lead can still enter water through older plumbing in individual homes. Contact your utility to learn about your specific service line and get a free water test.

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

Contact your water utility and ask if your address has been inventoried. They may have records on file. You can also hire a plumber to inspect the pipe at your property. Homes built before 1986 are more likely to have lead or galvanized pipes.

Is it safe to drink tap water in Arizona?

Arizona's water systems are regulated and must meet federal safety standards. Most tap water is safe. However, if you're concerned about lead in your home's plumbing, request a free test from your utility or have water tested independently.

What should I do if I find out I have a lead service line?

Talk to your water utility about replacement options and any available assistance programs. In the meantime, run water for 30 seconds before drinking, use cold water for cooking and baby formula, and ask your doctor about testing if young children live in the home.
