Lead Service Lines in Columbia Falls, MT

Columbia Falls serves about 14,000 residents through 43 water systems. Like many older communities, the area may have lead service lines—the pipes that connect homes to the public water main—but the extent is not yet fully documented.

What we know right now

The largest water system, Columbia Falls City of, serves about 4,450 people. Ridge Run serves roughly 3,500 residents. Together, these two systems cover the majority of the area's population. None of these utilities have yet reported confirmed lead service line inventories to state or federal regulators, which means the data is still being gathered or not yet public.

Lead service lines are a slow, preventable risk. Older homes (built before the 1980s) are more likely to have them, but age alone doesn't guarantee it. The only way to know for sure is to have your specific connection inspected or to ask your water utility directly.

What you can do now

Contact your water utility. If you live in Columbia Falls proper, reach out to the Columbia Falls City of water department and ask:

  • Does my property have a lead service line?
  • Do you have a map or inventory I can check?
  • What's your timeline for completing a full inventory?

If you're served by one of the smaller systems (Ridge Run, Meadow Lake, Big Sky, or Flathead County Water District No. 8), contact that system with the same questions.

Test your water. Even homes with lead lines often have low or undetectable levels if the water is treated properly. A simple lead test costs $20–30 at most hardware stores or through your county health department.

Know your home's age. Homes built before 1986 are at higher risk. If you know your house was built after 1990, lead service lines are unlikely—though not impossible.

Next steps for residents

  • Contact your water utility (listed below) and ask about lead service line status at your address
  • If you're unsure which system serves you, call the City of Columbia Falls public works department
  • Test your water if you're concerned; results take 1–2 weeks
  • Visit the EPA's lead service line page for additional resources and health information

Common questions

How do I know if I have a lead service line in Columbia Falls?

Contact your water utility (Columbia Falls City of, Ridge Run, or whichever system serves your address) and ask directly. You can also have a licensed plumber inspect the pipe where it enters your home, or request a water test to check for lead.

Is lead in Columbia Falls water dangerous?

Lead can be harmful, especially to children and pregnant people. However, the risk depends on whether you have a lead line and your water's treatment level. For health concerns, contact your pediatrician or the CDC's lead hotline at 1-800-CDC-INFO.

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

Use a water filter certified for lead (NSF/ANSI 53), test your water regularly, and flush your taps before drinking if water has sat overnight. Work with your utility on long-term replacement plans; many areas now offer rebates or low-interest loans.

When will Columbia Falls complete its lead service line inventory?

Utilities are required to complete inventories by 2027 under federal rule, though some may finish sooner. Call your local water system to ask about their timeline.
