Lead Service Lines in Missouri

What you need to know

Missouri serves about 6 million people through 3,013 water systems. Lead service lines—the pipes that connect your home to the public water main—are a concern in some communities, though the state hasn't yet reported the total number of known lead lines in its inventory.

Most water systems in Missouri have not yet completed their required lead service line inventories, which were mandated under the EPA's Lead and Copper Rule Revision. This means your utility may not yet know exactly what type of pipe delivers water to your home.

Why this matters

Lead can leach into drinking water, especially in homes with older plumbing or when water sits in pipes overnight. Even small amounts matter, particularly for children and pregnant women. If you live in an older home (built before the 1980s), your risk is higher.

What Missouri utilities are doing

The largest water systems in the state—including American Water (St. Louis and St. Charles counties), Kansas City PWS, St. Louis City, Springfield, Columbia, and Independence—are required to inventory their service lines and report findings to the EPA. However, most have not yet published their complete inventories publicly.

None of these utilities have reported known lead lines in the LeadPipeCheck database yet, but this reflects incomplete reporting rather than the absence of lead pipes.

Your next steps as a homeowner

1. Contact your water utility and ask: "Have you completed your lead service line inventory? What type of pipe delivers water to my home?" Utilities should provide this information.

2. Request a free water test from your utility—many offer this, especially if your system hasn't yet determined your line material.

3. Check your home's age and location. If you're in an older neighborhood (pre-1980s) near an older utility infrastructure, ask your utility specifically about lead risk in your area.

4. Consider a lead test if you're concerned, particularly if you have young children or a pregnant household member. Contact your local health department for guidance.

Next steps for residents

  • Call your local water utility and ask about their lead service line inventory status
  • Request information about what type of pipe serves your home
  • Ask whether your utility offers free water testing for lead
  • If you're concerned about health effects, contact your doctor or the CDC website for guidance

More on lead pipes in Missouri

Frequently asked about lead pipes in Missouri

Does Missouri have lead in the water?

Some Missouri homes may have lead service lines or galvanized pipes that can leach lead. Most utilities haven't completed their inventories yet, so the full extent is unknown. Contacting your water utility directly is the best way to learn about your specific area.

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

Contact your water utility and ask what type of pipe serves your home. You can also look where the water line enters your home—lead is soft, gray, and dents easily with a screwdriver. A utility inspection is the most reliable way to know.

Is Kansas City water safe to drink?

Kansas City PWS provides water to over 500,000 people and is required to test for lead. Contact the utility directly for their latest water quality report and lead service line inventory status.

What should I do if I'm worried about lead in my water?

Get a water test through your utility or a certified lab, use a pitcher filter for drinking and cooking water (if recommended), and let cold water run for 30 seconds before using it. For health concerns, especially with children, contact your pediatrician or local health department.
