Lead Service Lines in Kalispell, MT

Kalispell's water systems serve about 54,000 people across the area. The good news: current data shows no confirmed lead service lines have been identified in the city's inventories so far.

That said, lead in drinking water remains a real concern in many older homes across the country. Lead service lines—the pipes connecting your home to the water main—can leach lead into your water, especially if water is corrosive or acidic. If your home was built before the 1980s, there's a chance it could have a lead service line, even if your utility hasn't formally documented it yet.

What we know about Kalispell's water systems

The largest water provider in the area is Kalispell Public Works, which serves roughly 25,000 people. Other significant systems include Flathead County Water and Sewer (about 7,775 people) and smaller systems serving businesses and institutions like Glacier Park International Airport.

None of these systems have reported known lead service lines in current inventories. However, "no known lead" doesn't always mean "no lead"—it may mean the utility hasn't completed a full inventory yet, or records from decades past are incomplete.

What you can do right now

If your home is in Kalispell and was built before 1990, consider having your water tested. A simple test costs $20–50 at most hardware stores or through your local health department. The EPA recommends testing if:

  • Your home was built before 1986
  • You have young children or pregnant household members
  • You notice blue or green stains around faucets (a sign of corrosive water)

Contact your water utility to ask whether your property's service line material has been documented. Kalispell Public Works can tell you what they know about your specific address.

Next steps for residents

  • Get your water tested if your home is older or you're concerned about lead exposure
  • Contact your water utility to ask about your service line type and whether lead service line replacement programs exist
  • Check with the EPA's "My Water's Test Results" tool for your utility's most recent water quality report
  • If you have young children, talk to your pediatrician about lead exposure risks and testing options

Common questions

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

Contact Kalispell Public Works or your specific water utility with your address—they may have records of your service line material. You can also have a licensed plumber inspect the pipe at your property line. Older homes (pre-1986) are more likely to have lead lines.

Is the water in Kalispell safe to drink?

Kalispell's water systems currently report no known lead service lines. However, if you're concerned about lead specifically, a simple water test ($20–50) can tell you whether lead is present in your tap water.

What should I do if my child was exposed to lead in water?

Contact your pediatrician or your state health department. The CDC offers guidance on lead exposure in children and steps to reduce risk. A blood lead test can determine if exposure occurred.

Does Kalispell offer help replacing lead service lines?

Contact Kalispell Public Works directly to ask whether the city or county has a lead service line replacement program or rebates available. Many utilities now offer financial assistance for replacements.
