Lead Service Lines in Bellingham, WA

What we know about lead in Bellingham

Right now, no lead service lines have been reported in Bellingham's public inventory data. This is good news—but it comes with an important caveat: utilities are still in the early stages of mapping their systems. Some water systems may not have completed their lead line surveys yet, which means the absence of reported lead doesn't guarantee none exist.

Lead service lines are pipes that connect your home to the water main under the street. They were commonly installed before 1986, when federal regulations began phasing them out. If your home was built before the 1990s, there's a possibility—however small—that your connection could include lead.

How to find out about your home

Your water utility has the most direct answer. Contact the Bellingham Water Division or your local system (see the list above) and ask:

  • Does a lead service line connect my home to the water main?
  • When was my home's connection last inspected or tested?
  • Do you have a map or inventory I can check?

Most utilities are creating these inventories now under EPA and state requirements, so they may be able to tell you whether your address is flagged for further investigation.

If you're concerned about lead in your tap water

The only way to know if lead is actually in your drinking water is to test it. This is different from knowing whether you have a lead line—a lead line doesn't always mean contaminated water, but it's a risk factor. You can buy an affordable lead test kit or contact your utility for guidance on testing.

If you have young children in your home, talk to your pediatrician about testing recommendations. The CDC has detailed guidance on lead exposure and steps to reduce risk.

Next steps for residents

  • Contact your water utility (Bellingham Water Division for most city residents) and ask about lead service line status for your address
  • Request a water test if you want to check for lead in your tap water
  • Ask about their timeline for completing lead line inventories—most utilities have specific deadlines under state law
  • Review the utility's lead service line inventory once it's published; utilities are required to make this information public

Common questions

Does Bellingham have lead in the water?

No lead service lines have been reported in current inventory data, but utilities are still mapping their systems. The only way to know if lead is in your tap water is to test it. Contact your water utility to ask about your home's connection and request a test if you're concerned.

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

Call the Bellingham Water Division (or your local water provider) and ask about your address specifically. They may have records of your connection or can tell you whether your home is in an area flagged for lead line surveys.

Is lead service line water safe to drink?

A lead line doesn't always mean contaminated water—it depends on water chemistry, pipe condition, and other factors. Testing is the only reliable way to know. If you have young children, talk to your pediatrician about lead exposure risks and testing.

When will Bellingham water utilities finish their lead inventory?

Washington state law requires utilities to complete lead service line inventories by specific deadlines. Contact your water provider directly to ask about their timeline and when results will be public.
