Naperville Lead Service Line Inventory
Naperville serves roughly 156,000 residents. Like all US water utilities, Naperville is required by federal law to identify and report on lead service lines in its system—pipes that may expose your home's drinking water to lead.
What we know about Naperville's lead service lines
Naperville has not yet publicly reported on lead service line inventory data. This means the utility has either not completed its inventory, not submitted findings to regulators, or has not made the results publicly available online.
This is not unusual. The EPA's deadline for most utilities to complete lead service line inventories was October 2024, with additional flexibility for systems serving smaller populations or those with limited data access. Even after completion, utilities may take time to publish results publicly.
What you can do now
Contact Naperville directly to ask about:
- Whether a lead service line inventory has been completed
- Results specific to your address or neighborhood
- Any timeline for replacing lead service lines
- Water quality testing programs you can use
You can reach Naperville's water utility through the City of Naperville's official website or call their public works department.
Test your water if you're concerned. A simple lead test costs $20–50 and takes about a week. Contact your local health department for lab recommendations, or visit the EPA's testing guidance.
Reduce exposure at home while you wait:
- Run cold water for 30 seconds before drinking or cooking (especially first thing in the morning)
- Use cold water for cooking and baby formula
- Clean aerators on faucets regularly
If young children or pregnant people live in your home, talk to your pediatrician or OB-GYN about lead exposure risk. The CDC offers resources on health effects and prevention.
Next steps for residents

Frequently asked
Does Naperville have lead service lines?
Naperville has not yet publicly released lead service line inventory data. Contact the utility directly to ask about the status of their inventory and any results for your area.
How do I know if my house has a lead service line?
Your water utility can tell you based on their records and your address. You can also have a plumber inspect the pipe where it enters your home, or test your water for lead.
Is lead in water dangerous for kids?
Lead exposure can affect children's development and learning. Talk to your pediatrician about testing and prevention steps. The CDC website has detailed information on health effects and safe practices.
Can I remove lead from my tap water myself?
A certified water filter (NSF/ANSI Standard 53) can reduce lead, but replacing or sealing the service line is the only permanent fix. Boiling water does not remove lead.
