YNP-OLD FAITHFUL Water System: Lead Service Line Inventory
About this water system
YNP-OLD FAITHFUL serves approximately 7,675 people in Wyoming. The system draws from surface water sources.
Lead service line inventory status
This water system has not yet inventoried its lead service lines. As of now, there is no public count of how many lead, galvanized, or non-lead pipes connect homes to the main water supply.
Federal rules require all water systems to complete a lead service line inventory by October 2024. That deadline has passed for most utilities. If YNP-OLD FAITHFUL has completed its inventory since this page was last updated, contact the utility directly to ask for the results.
What you should do now
Even without a public inventory, you can take steps to protect your household:
Contact your water utility. Ask them directly:
- Does my address have a lead service line?
- What is the status of their lead inventory?
- Do they have a replacement program or timeline?
Test your water. A simple lead test costs $20–50 and takes a few days. Contact your local health department for a list of certified labs, or ask your utility for a free or discounted test kit.
Use filters if needed. If your water tests positive for lead, NSF-certified filters marked for lead removal can reduce it while you arrange replacement. The CDC recommends flushing your tap for 30 seconds before drinking or cooking if your home has lead pipes.
Know your risk factors. Homes built before 1986 are more likely to have lead service lines. If your house was built around that time or earlier, ask your utility about your line material even if the inventory isn't complete yet.
Funding for replacement
Information about replacement funding for this system is not currently available. When utilities receive federal funding (like grants under the Bipartisan Infrastructure Law), they often announce replacement programs. Check your utility's website or call their customer service line.
Next steps for residents
- Contact YNP-OLD FAITHFUL directly to ask about your service line and the inventory status
- Get your water tested through a certified lab (ask your utility or health department)
- Check your home's age — built before 1986? Lead pipes are more common
- Review CDC guidance on lead and drinking water if you have young children or pregnant household members

Frequently asked
How do I know if I have a lead service line?
Contact your water utility and ask directly about your address. You can also look at where your water meter enters your home — if it's soft, shiny, and leaves a gray mark when scratched, it's likely lead. A water test will show if lead is actually in your water.
Is the water in Old Faithful safe to drink?
This inventory page covers service lines only, not overall water safety. For current water quality results, visit your utility's annual water quality report (required by federal law) or call them directly.
What should I do if my water tests positive for lead?
Use an NSF-certified filter rated for lead, flush your tap for 30 seconds before drinking or cooking, and contact your utility about replacement options. If you have young children or are pregnant, talk to your pediatrician or doctor — the CDC has specific guidance for those groups.
Will my water utility replace my lead service line for free?
Some utilities offer free or subsidized replacement programs, especially with recent federal funding. Contact YNP-OLD FAITHFUL to ask about their program, timeline, and eligibility.
