Lead Service Lines in Montana

Montana serves approximately 1.1 million people through 2,386 public water systems. Currently, there are no confirmed lead service lines reported across the state's inventory.

This doesn't necessarily mean lead service lines don't exist in Montana—it means they either haven't been identified yet, or utilities have not reported them. Lead service line detection and replacement is an ongoing process, and many water systems are still in the early stages of surveying their infrastructure.

Why this matters

Lead service lines are underground pipes that connect your home to the public water main. When water sits in these pipes, especially if the water is acidic or soft, lead can leach into your drinking water. Even small amounts can be a concern for children and pregnant people.

If your home was built before the 1980s, there's a higher chance you have a lead service line—particularly if you live in an older neighborhood.

What Montana utilities are doing

Montana has not yet received federal Infrastructure Investment and Jobs Act (IIJA) funding to support lead service line replacement. This means replacement programs may be limited or unavailable in your area at the moment.

However, utilities are still required by federal law to:

  • Maintain an inventory of known and suspected lead service lines
  • Inform customers if lead has been detected in their water
  • Provide guidance on reducing lead exposure

How to find out about your home

Your water utility has records that may indicate whether your service line contains lead. Some utilities have already surveyed their pipes; others are still conducting inventories.

Contact your local water utility directly and ask:

  • Does your system have a lead service line inventory?
  • Do they know or suspect your home has a lead service line?
  • What testing options are available?

Many utilities can review old property records, pipe materials, and service line history to give you an answer.

If you're concerned about lead in your water

You can request a free or low-cost water test from your utility. If results show elevated lead levels, simple steps like flushing your lines or installing a point-of-use filter can help while replacement is arranged.

For health concerns, contact your doctor or the CDC's lead information line.

Next steps for residents

  • Call or visit your water utility's website and ask about their lead service line inventory status
  • Request a water test if you're concerned about lead
  • If your home was built before 1980, ask specifically whether they've identified your service line material
  • Check the utility contact information linked on this page for the systems serving your area

Frequently asked about lead pipes in Montana

Does Montana have lead service lines?

Montana's public water systems currently report zero confirmed lead service lines. However, inventories are ongoing, and some older homes may still have lead or galvanized pipes that haven't been surveyed yet.

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

Contact your local water utility and ask about their service line inventory. They can often look up your address in their records or describe what material your line is made of based on your home's age and location.

Is there funding for lead service line replacement in Montana?

Montana has not yet received federal Infrastructure Investment and Jobs Act funding for lead service line replacement. Check with your utility about any local or state programs that might help with costs.

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

Request a free or low-cost water test from your utility. If lead is detected, let your water run for 30 seconds before using it, and consider installing a certified point-of-use filter while you explore replacement options.
