Lead service lines in Vancouver, WA

What we know about lead service lines in Vancouver

Public data on lead service line inventories in Vancouver is currently limited. The water systems serving the area have not yet reported confirmed counts of lead service lines to state or federal authorities, or those counts are not yet publicly available. This does not mean lead service lines are absent—it means the inventory work is still underway or data hasn't been published.

Lead service lines are pipes that connect your home's water meter to the main water line buried under the street. If your home was built before 1986, there's a higher chance your service line contains lead. Lead is also sometimes found in older fixtures, solder, and brass components inside homes.

Why this matters

Lead in drinking water is a real health concern, especially for young children and pregnant people. Even small amounts of lead exposure can affect development and learning. The EPA and CDC recommend that anyone with a lead service line take steps to reduce exposure while replacement is being planned.

What you can do now

Find out what your water system knows. Contact your utility directly and ask:

  • Does our system have a lead service line inventory?
  • If yes, is my address on it?
  • If no, when will the inventory be complete?

Learn your home's service line material. Look at your water meter pit (usually in your basement, crawl space, or outside near the street). A magnet will not stick to copper or plastic; it will stick to steel. Lead is soft and silvery-gray. If you're unsure, a plumber can help identify it.

If you have a lead service line, the EPA recommends using a water filter certified to remove lead (look for NSF/ANSI 53 certification) while you plan for replacement. Flushing taps before use and using cold water for drinking and cooking are also protective steps.

Next steps for residents

  • Contact Vancouver City of (373,047 customers) or Clark Public Utilities (153,526 customers) to ask about lead service line inventory status
  • Request a water quality report if you haven't received one
  • If you suspect a lead service line, consult a licensed plumber
  • For health concerns, speak with your pediatrician or contact the CDC

Common questions

Does Vancouver have lead in the water?

Lead is not added to water by treatment plants. It enters water through pipes and fixtures, especially older service lines made of lead. Current data on lead service lines in Vancouver is limited, so contact your water utility to learn about your specific address.

How do I know if my house has a lead service line?

Homes built before 1986 are more likely to have lead service lines. You can inspect the pipe at your water meter (usually soft, silvery-gray) or ask your utility if your address is on a lead service line inventory. A plumber can also identify it.

Is a lead service line dangerous?

Lead in drinking water poses real health risks, especially for children and pregnant people. If you have a lead service line, using a certified water filter and taking other protective steps can reduce exposure while you plan for replacement.

Who do I call to replace a lead service line in Vancouver?

Contact your water utility (Vancouver City of or Clark Public Utilities) to ask about replacement programs, cost-sharing, or grants. Some utilities offer assistance to customers replacing lead service lines.
