Lead Service Lines in Idaho Falls
What you need to know
Idaho Falls City serves about 69,450 people. The water system uses groundwater as its primary source.
Current status: The system has not yet completed an inventory of lead service lines. This means the city does not yet have a public count of how many homes are connected to lead pipes.
Why this matters
Lead service lines are pipes made of lead that connect water mains in the street to homes. When lead pipes corrode, lead can enter drinking water. This is a real concern, but it's manageable with the right steps.
The EPA and CDC recommend that all water systems in the US identify where lead service lines exist so residents know their risk level. Idaho Falls is still in the early stages of this process.
What Idaho Falls should be doing
Water systems are required to complete lead service line inventories and share results publicly. If you haven't heard from Idaho Falls about this yet, it's likely they're still working through the initial assessment phase.
What you can do now
Contact your water utility directly to ask:
- Whether your home has a lead service line
- When the city plans to complete its inventory
- What interim steps they recommend (like flushing or testing)
The city's water department can often tell you based on your address and the age of your home, even if the full inventory isn't public yet.
Test your water if you're concerned. A simple lead test costs $20–40 and gives you a direct answer for your home.
Filter your water while you investigate. NSF-certified filters designed for lead removal work; pitcher filters (like Brita) do not.

Frequently asked
Does Idaho Falls have lead in the water?
Idaho Falls uses groundwater, which is less corrosive than surface water and less prone to lead problems. However, lead service line pipes can still corrode and release lead. The city hasn't completed an inventory yet, so specific data isn't public. Contact the water department for your address.
How do I know if my house has a lead service line?
Call Idaho Falls City water department with your address—they often know based on installation records and neighborhood age. Alternatively, hire a plumber to inspect the pipe where it enters your home. You can also test your water for lead directly.
Is it safe to drink tap water in Idaho Falls?
Idaho Falls water is treated and monitored. Lead risk depends on whether your specific home has a lead service line or plumbing. If you're concerned, test your water or use a lead-removal filter while you investigate.
When will Idaho Falls replace lead pipes?
The city hasn't yet published a timeline. Contact the water department to ask about their replacement plan and when they expect to begin work in your neighborhood.
