What we know about lead service lines here

The inventories available so far don't show any confirmed lead service lines in Portland. That's good news—but it comes with an important caveat: most utilities are still completing their lead service line surveys. "Unknown" doesn't mean "safe." It means the work is ongoing.

Portland Water District-Greater, which serves the vast majority of the city, has not yet reported specific lead service line counts. The smaller utilities serving areas like Chebeague Island, Camp Sebago, and Steep Falls are also in the data-collection phase.

Why this matters for your home

A lead service line is the pipe connecting your water meter to the main water line under the street. If your home was built before the 1980s—especially before 1950—there's a higher chance your service line contains lead or lead-bearing materials.

Lead can leach into drinking water, particularly if your water is acidic or sits in pipes for hours (like overnight). Even trace amounts matter for young children and pregnant people. The CDC recommends testing if you're concerned.

Your next steps

Start by contacting your local water utility. Ask directly:

  • Does my address have a known lead service line?
  • If unknown, when will my area's survey be complete?
  • Can you provide guidance on water testing or flushing?

If you want to know your service line status right now, the utility may have maps or records—many don't publish them online yet, but staff can often tell you over the phone if you have an address.

For drinking water, consider a simple test (labs cost $15–50) or a point-of-use filter certified for lead if you want extra peace of mind while surveys continue.

Common questions

Does Portland Maine have lead in the water?

Lead service lines—the pipes connecting homes to the main water line—haven't been confirmed in Portland's inventory data so far, but most utilities are still surveying. Contact Portland Water District-Greater directly to learn if your address has been checked yet.

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

Call your water utility with your address; they may have records or be able to check your area's survey status. Homes built before the 1980s are at higher risk. You can also hire a plumber to inspect the pipe where it enters your house.

Is it safe to drink Portland Maine tap water?

Portland's water systems test for lead regularly and report results to the state. If you're concerned about your specific service line, ask your utility for their latest water quality report or contact the Maine Department of Environmental Protection.

What should I do if I think I have a lead service line?

Contact Portland Water District-Greater (the main utility) to confirm your service line status. If it's lead, you can reduce exposure by flushing lines before drinking, using cold water for cooking, and considering a certified lead-removing filter.
