Lead Service Lines at NAS NORTH ISLAND & NAB CORONADO
NAS NORTH ISLAND & NAB CORONADO serves approximately 36,990 people in California. Like all water systems in the United States, it is required by federal law to identify and inventory lead service lines—the pipes that connect homes to the public water main.
What we know right now
This water system has not yet completed or made public a lead service line inventory. That means the utility has not published a count of how many lead pipes serve its customers, or a map showing which neighborhoods are affected.
This is not uncommon. Many water systems across the country are still in the early stages of inventory work. Federal law requires all systems to complete their inventories by October 2024, with updated lists due periodically afterward.
Why this matters
Lead service lines are a real health concern, especially for young children and pregnant people. If your home was built before the 1950s, or if your neighborhood has older infrastructure, there's a higher chance your connection includes lead pipes. Lead can leach into drinking water, particularly if water is stagnant or acidic.
The good news: lead in water is preventable and treatable through flushing, filtration, and—most permanently—pipe replacement.
What you can do now
Contact your water utility directly. Call NAS NORTH ISLAND & NAB CORONADO and ask:
- Does my address have a lead service line?
- Do you have a partial inventory or map available?
- What is your timeline for completing the full inventory?
- Are there any replacement programs or financial assistance available?
Get your water tested. If you're concerned about lead, a simple water test can tell you whether lead is present in your home's water. Many health departments offer low-cost or free testing. Contact your local San Diego County health department.
Consider a water filter. NSF-certified filters rated for lead reduction (such as reverse osmosis or specific activated carbon filters) can reduce lead in drinking and cooking water while you wait for testing or replacement.
For health questions—especially if you have a young child—talk to your pediatrician or contact the CDC's lead information line.

Frequently asked
How do I know if my house has a lead service line?
Your water utility's lead service line inventory should show this. If the inventory isn't complete yet, you can ask your utility directly about your address, or hire a plumber to inspect your pipes. Homes built before the 1950s are at higher risk.
Is lead in water dangerous?
Yes, lead can cause serious health problems, especially in children and pregnant people. The best approach is testing your water, using a certified filter, and asking your utility about pipe replacement programs. For health concerns, contact your pediatrician or the CDC.
What should I do if my water has lead?
Use boiling, filters certified for lead (NSF-certified reverse osmosis or activated carbon), or bottled water for drinking and cooking. Contact your utility about long-term solutions like lead service line replacement, which is often the only permanent fix.
Does my water utility have to replace lead pipes?
Federal law now requires water systems to replace lead service lines over time, though timelines vary. Ask your utility about their replacement program and whether you qualify for financial assistance or cost-sharing.
