Lead Service Lines in TREASURE ISLAND, California
What you need to know
TREASURE ISLAND serves about 3,864 people in California. Like many US water systems, it relies on a lead service line inventory—a record of pipes that may deliver water to your home.
The current situation: TREASURE ISLAND has not yet completed its lead service line inventory. This means the utility does not yet have a full count of how many homes may be served by lead pipes.
Why this matters
Lead service lines are one of the most common sources of lead in drinking water. When water sits in these pipes—especially if it's acidic or soft—lead can leach out. Even low levels of lead exposure over time can pose health risks, particularly for young children and pregnant people.
Not having a completed inventory doesn't mean there's no lead in the system. It means the utility is still in the process of identifying where lead pipes exist so they can plan replacements.
What happens next
Water systems across the country are required to complete lead service line inventories under federal rules. Once TREASURE ISLAND finishes its count, you'll be able to find out:
- Whether a lead service line connects your home to the street main
- The utility's timeline for replacing lead pipes
- Any interim steps to reduce lead exposure while pipes remain in place
The utility should have published its findings and replacement schedule by law. Check your water bill or the utility's website for updates, or contact them directly.
If you're concerned about lead in your water
Testing your water is straightforward. Many health departments offer free or low-cost lead tests. If you'd like to know your home's lead levels before the utility completes its inventory, this is a practical next step.
Next steps for residents
- Contact TREASURE ISLAND directly to ask about the status of their lead service line inventory and whether your address has been surveyed
- Request a free water test through your local health department if you want to check lead levels at your tap now
- Review your water bill for notices about lead and the utility's replacement plans
- Talk to your pediatrician or local health department if you have health concerns about lead exposure

Frequently asked
How do I know if I have a lead service line?
Your water utility's lead service line inventory will tell you. You can also contact your utility directly with your address. If the line connecting your home to the street main was installed before 1986, there's a higher chance it's lead, though many older pipes are other materials.
Is lead in drinking water dangerous?
Lead exposure, especially for children under 6 and pregnant people, can affect development and health even at low levels. For specific health concerns, talk to your doctor or call the CDC at 1-800-CDC-INFO. Testing your water is a good way to know your actual exposure risk.
What should I do if my water utility hasn't finished its inventory yet?
Contact your utility to ask for a timeline and whether your home has been surveyed. You can also get your water tested independently through your local health department. The utility is required by law to complete and publish its inventory.
Can I replace my lead service line myself?
You can replace the portion on your property, but the portion under the street is typically the utility's responsibility. Contact your water utility to ask about their replacement program and any financial assistance available.
