Lead Service Lines in GSWC - FLORENCE/GRAHAM
GSWC - FLORENCE/GRAHAM serves about 63,500 people in California. Like all US water systems, it is required to maintain an inventory of lead service lines—the pipes that connect homes to the public water main—and share that information with customers.
What we know about this system
This water utility has not yet completed or published a lead service line inventory. This does not mean there are no lead service lines; it means the work of identifying and cataloging them is still underway or the results have not been made publicly available.
The Safe Drinking Water Act requires water systems to:
- Locate and count lead service lines in their network
- Tell customers which homes may have them
- Develop and fund a plan to replace them over time
Why this matters
Lead service lines pose a real health risk, especially to young children and pregnant people. Lead can leach into drinking water, particularly from older pipes or when water is corrosive. However, risk varies widely based on your home's age, your water's chemistry, and whether you're using a filter.
If your home was built before 1986, it is more likely (but not certain) to have a lead service line.
What you can do now
Contact your water utility directly. GSWC - FLORENCE/GRAHAM can tell you whether your specific address has a known or suspected lead service line. They may have partial data even if a full inventory isn't public yet.
If you're concerned about lead in your tap water:
- Get your water tested (your utility or county health department can advise on low-cost options)
- Use a water filter certified to remove lead (NSF/ANSI Standard 53)
- Flush your tap for 30 seconds before drinking if water has sat unused overnight
For health questions, contact your pediatrician or the CDC. Lead exposure is preventable, and there are clear steps you can take to protect your family.

Frequently asked
How do I know if my home has a lead service line?
Contact your water utility—GSWC - FLORENCE/GRAHAM—and ask if your address is documented in their inventory. If the utility doesn't have records, you can also check your home's age (built before 1986 is a risk factor) and ask a licensed plumber to inspect the line where it enters your house.
Is lead service line water safe to drink?
Risk depends on your water's chemistry and how long water sits in the pipe. Some homes with lead lines have low lead levels; others don't. The safest approach is to get your water tested and use a certified lead-removing filter while longer-term replacement is planned.
Can I replace my lead service line myself?
Most utilities require licensed professionals to replace service lines because improper work can contaminate the water supply. Contact GSWC - FLORENCE/GRAHAM about their replacement program and any cost-sharing or rebate options.
What should I do if I have young children and think I have a lead service line?
Get your water tested immediately, use a certified lead filter on your drinking water, and contact your pediatrician. Lead exposure is preventable; your doctor can also discuss screening if you're concerned.
