Lead Service Lines in Maine

Maine's 1,733 water systems serve about 922,000 people. Right now, the state has not reported any confirmed lead service lines in its public inventories. However, this doesn't mean lead pipes don't exist in Maine—it often means utilities haven't finished surveying their systems yet.

Why the uncertainty?

Water utilities across the US are still mapping their underground pipes. Many systems, especially smaller ones, have incomplete records of what material their service lines (the pipes that connect the main water line to your home) are made from. A utility might know the main line is copper but have no documentation about what's buried under your property.

Lead service lines pose a real health risk, especially for young children and pregnant people. If you have a lead line, water can pick up lead as it travels to your tap—though the risk depends on the water's chemistry, age of the pipe, and other factors.

Maine's six largest water systems

The state's biggest utilities are:

  • Portland Water District (135,068 people)
  • Maine Water Company Biddeford Saco Division (42,508 people)
  • Kennebunk, Kennebunkport & Wells Water District (35,663 people)
  • Bangor Water District (27,298 people)
  • Lewiston Water & Sewer Division (23,720 people)
  • Kennebec Water District (22,060 people)

What you can do now

Contact your local water utility and ask:

  • Does your service line contain lead?
  • Do they have records of your line's material?
  • If they don't know, ask what's the timeline for completing a survey.

If your utility hasn't completed its inventory, ask for their current findings and expected completion date. You can also request a free or low-cost water test—many utilities offer them.

For health questions about lead exposure, consult the CDC website or your pediatrician.

Next steps for residents

  • Find your water utility by address on your water bill or contact your town's public works department
  • Ask about your service line — request written confirmation of the material
  • Get your water tested if your line is unknown or confirmed lead
  • Visit LeadPipeCheck to see if your utility's inventory data has been updated

More on lead pipes in Maine

Frequently asked about lead pipes in Maine

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

Contact your water utility with your address and ask for your service line material. You can also dig up the pipe near your home if you're doing yard work—lead is soft, gray, and dents easily with a coin. If you're unsure, a water test can detect lead in your tap water.

Is lead in Maine water a big problem?

Maine hasn't reported confirmed lead service lines yet, but that reflects incomplete surveys, not the absence of lead pipes. Older homes and systems are at higher risk. If you have a lead line, the risk depends on your water's acidity and how long water sits in the pipe.

What should I do if my service line is lead?

Have your water tested and consider flushing it before drinking or cooking. Long-term, replacement is the safest solution. Ask your utility about replacement programs or rebates—some offer help with costs.

Can I get a free water test in Maine?

Many Maine water utilities offer free or subsidized testing. Contact your local utility directly. The EPA also funds testing programs—ask your utility or town if one is available in your area.
