Lead Service Line Inventory for West Yellowstone
What you need to know
The Town of West Yellowstone serves about 9,900 people in Montana. Like many US water systems, the town is required by federal law to identify and report on lead service lines—the pipes that connect the water main in the street to homes and buildings.
Current status: West Yellowstone has not yet completed a full inventory of its lead service lines. This means the town is still in the process of identifying which properties have these pipes, or has not yet made that data public.
Why this matters
Lead service lines can pose a health risk, especially to young children and pregnant people, because lead can leach into drinking water—particularly from older pipes or when water is corrosive. Even low levels of lead exposure can affect child development.
The good news: lead service lines only become a problem when water reaches your home through them. Flushing pipes, using a certified water filter, or fully replacing the line can reduce your risk.
What West Yellowstone is required to do
Federal law requires all water utilities to:
- Inventory lead and galvanized service lines
- Publish findings and a replacement plan
- Offer corrosion control and treatment to reduce leaching
West Yellowstone draws its water from groundwater sources, which tend to be less corrosive than surface water—but your home's pipes and fixtures still matter.
How to find out about your home
Contact the Town of West Yellowstone water utility directly and ask:
- Does my property have a lead service line?
- What is the status of the town's inventory?
- Are there steps I can take now to reduce exposure?
They can tell you if your address has been assessed and what options are available.
Next steps for residents
- Call your water utility to ask about your specific property and the timeline for completing the inventory.
- Consider water testing if you're concerned; a certified lab can check for lead in your drinking water.
- Learn about filters — NSF/ANSI Standard 53 certified filters reduce lead if you have a lead service line.
- Check the CDC's guidance on lead and water safety for children and pregnancy.
