EAST BAY MUD Lead Service Line Inventory
East Bay MUD serves approximately 1.4 million people across the East Bay region of California. Like all U.S. water systems, the utility is required to identify and inventory lead service lines—the pipes that connect homes to the public water main.
What is a lead service line?
A lead service line is a water pipe made of lead that runs underground from the public water main to your home. For decades, lead was a standard material for these connections because it was inexpensive and durable. We now know that lead can leach into drinking water, especially in homes with older plumbing or corrosive water conditions.
Where is EAST BAY MUD's inventory?
EAST BAY MUD has not yet published a searchable online inventory of lead service lines. This means you cannot currently look up your address on a public map or database to learn whether your home has a lead service line.
This is not unusual. Many water systems across the country are still compiling their inventories and deciding how to make that information public. The utility may have partial data or be in the process of gathering it from municipal records, field surveys, or both.
What should you do now?
Even without a public inventory, you have options:
Contact EAST BAY MUD directly. Call or email the utility and ask whether your address has a known lead service line. If records exist, they may share them with you. The utility can also tell you about any ongoing inventory or replacement projects in your area.
Get your water tested. If you're concerned about lead, a certified lab can test your drinking water for lead content. California has resources to help you find a lab. Results will tell you whether lead is actually present in your water right now.
Know your home's age. Homes built before 1978 are more likely to have lead service lines, though age alone doesn't guarantee it. Knowing when your house was built can help focus your concern.
Ask about replacement programs. Some water systems and local governments offer partial funding or low-cost replacement of lead service lines. EAST BAY MUD may have information about such programs.

Frequently asked
How do I know if my house has a lead service line?
Contact EAST BAY MUD and ask about your address—they may have records. You can also hire a plumber to inspect the line where it enters your home, though it's buried underground. The utility can tell you about any inventory data they've collected.
Is lead in my water dangerous?
Lead in drinking water can pose health risks, especially for children and pregnant people. For specific health concerns, talk to your doctor or contact the CDC. A water test will tell you whether lead is actually present in your home.
What should I do if I think I have a lead service line?
First, get your water tested. Second, contact EAST BAY MUD to ask about replacement programs or financial assistance. In the meantime, you can reduce risk by flushing cold water before drinking and using cold water for cooking.
When will EAST BAY MUD publish a lead service line map?
The utility has not yet published a searchable online inventory. Contact them directly to ask about their timeline for completing the inventory and making it public.
