Lead Service Lines in Stockton, California

California Water Service serves about 176,000 people in Stockton. Lead service lines—the pipes that connect the water main to individual homes—are a significant concern in older water systems, and knowing your home's situation is an important first step toward protecting your family's health.

What we know about Stockton's lead pipes

California Water Service - Stockton draws water from surface sources. The utility has not yet completed a full inventory of lead service lines in its service area. This means the exact number of homes with lead pipes is currently unknown.

The federal Lead and Copper Rule requires all water systems to identify and track lead service lines. Stockton's utility is working toward this requirement, but the inventory data is not yet publicly available or has not been reported to state regulators.

Why this matters

Lead can leach from service lines into drinking water, especially in homes with older plumbing or where water is acidic or soft. Children under 6 are at highest risk for developmental effects from lead exposure. Even low levels matter over time.

Not having a completed inventory doesn't mean there are no lead pipes—it means the exact picture is still being developed. Many systems across the country, especially those built before 1980, have significant numbers of lead service lines.

What you can do now

Find out if your home has a lead service line. Contact California Water Service - Stockton directly and ask:

• Does your system have records showing what material your service line is made of?
• Can they perform a free or low-cost inspection?
• Are they offering replacement assistance programs?

Test your water. Even if you don't know your service line material, you can have your drinking water tested for lead. Your local health department can point you to certified labs, and testing typically costs $20–50.

Use filters if needed. If your water tests high for lead, a certified pitcher filter or faucet filter can reduce it while you pursue longer-term solutions like line replacement.

Check with your city. Stockton's municipal government may have additional lead remediation programs or grants available to residents.

Next steps for residents

• Contact your water utility directly: ask them what they know about your property's service line material.
• Request a water test through a certified lab or your county health department.
• Ask about replacement programs: some utilities offer partial funding or contractor lists for lead line removal.
• Review CDC guidance on lead in drinking water at cdc.gov if you have health concerns.
