KAANAPALI Water System: Lead Service Line Information
About KAANAPALI
KAANAPALI serves approximately 8,000 people in Hawaii. The system draws from groundwater sources. Like all US water systems, KAANAPALI is required by federal law to identify and track lead service lines—the pipes that connect the water main to homes.
Lead service line inventory status
KAANAPALI has not yet completed a public inventory of lead service lines. This means the utility has not published a count of how many homes may have lead pipes, or what percentage of the system they represent.
This is not unusual. The federal Lead and Copper Rule requires all water systems to inventory their service lines by October 2024, with ongoing updates required. Many smaller systems are still compiling this data, especially in states like Hawaii where lead pipes are less common due to the age and construction patterns of the infrastructure.
What you can do right now
Until the inventory is complete and public, you have several options:
Ask your utility directly. Contact KAANAPALI and ask:
- Do you know if my address has a lead service line?
- What year was my property built?
- Do you have a map or list I can check?
Many utilities can answer these questions even before publishing a formal inventory.
Test your water. If you're concerned about lead exposure—especially if you have children under 6 or are pregnant—you can have your water tested. The EPA recommends testing the water that comes out of your tap. Your utility can often provide a free or low-cost test kit, or refer you to a certified lab.
Know the signs. Lead service lines pose the greatest risk if water sits unused for hours (like overnight), or if your water is naturally corrosive (soft or acidic). Running cold water for 30 seconds before drinking or cooking can reduce exposure. Boiling water does not remove lead.
Health questions
If you're worried about lead exposure, talk to your doctor or pediatrician. For general information about lead in drinking water and health effects, visit the CDC's lead in water page.

Frequently asked
Does KAANAPALI have lead pipes?
KAANAPALI has not yet published a complete public inventory of lead service lines. Groundwater systems in Hawaii tend to have fewer lead pipes than older surface-water systems on the mainland, but the only way to know about your home is to ask the utility directly or have your water tested.
How do I know if my house has a lead service line?
Contact KAANAPALI and ask. They can often check their records for your address or tell you when your home was built and what materials were used. You can also have your water tested, though that doesn't directly show the pipe material.
Is lead in drinking water dangerous?
Lead can be harmful, especially to children under 6 and pregnant people. For detailed health information and specific guidance for your situation, contact the CDC or speak to your doctor.
What should I do if I'm worried about lead in my tap water?
Ask your utility for a free water test, run cold water for 30 seconds before drinking or cooking, and talk to your pediatrician if you have health concerns. Boiling water does not remove lead.
