NAMPA CITY OF Lead Service Line Inventory
Nampa City of serves about 100,200 people in Idaho. Like many water systems across the US, it uses a mix of infrastructure to deliver water—in this case, primarily groundwater sources.
What we know about lead service lines in Nampa
A lead service line (LSL) is the pipe that connects your home to the main water line under the street. If your home was built before the 1980s, there's a chance your service line contains lead. Nampa City of has not yet completed a full inventory of lead service lines in its system, so we don't have current data on how many homes may be affected.
The EPA requires all water systems to develop and publish lead service line inventories by October 2024 (with a possible extension to October 2025 for some utilities). Nampa City of is working to meet this deadline.
Why this matters
Lead doesn't usually affect the taste, smell, or appearance of water. The only way to know if lead is present is through testing or knowing your home's pipe material and age. Exposure to lead in drinking water poses health risks, especially for young children and pregnant people.
What you can do now
Contact Nampa City of directly to ask about:
- Whether your address has been identified as having a lead service line
- When the full inventory will be available
- Free or reduced-cost water testing options
- Whether your home qualifies for assistance with pipe replacement
You can also request this information in writing—water utilities are required to respond to public records requests about lead inventories.
In the meantime, if your home was built before 1980, consider getting your water tested by a certified lab. A simple test costs $20–$50 and takes a few days for results.
Next steps for residents
