Lead Service Line Compliance in Massachusetts
Massachusetts water utilities serve about 10.3 million people across 1,651 public water systems. Under the federal Lead and Copper Rule Revision (LCRR), all of these systems are required to create and submit inventories of their lead service lines—the pipes that connect the main water line to individual homes—by October 2024.
What Massachusetts utilities reported
As of October 2024, Massachusetts utilities submitted their lead service line inventories to the state primacy agency (the Massachusetts Department of Environmental Protection). The data shows that across the state's water systems, the number of lead service lines identified as "known" is currently recorded as 0, with 0 lines classified as "unknown." This suggests either that utilities have completed their surveys with high confidence, or that reporting and data consolidation is still underway at the state level.
It's important to note that final compliance determinations and enforcement actions—if any—typically take several months after the October deadline. The state primacy agency is responsible for reviewing each utility's inventory for completeness and accuracy.
Why this matters for your home
If you live in Massachusetts, your water utility should be able to tell you whether your home has a lead service line. Even if utilities report low or zero lead service lines statewide, individual systems may have found lines during their surveys. The only way to know for certain is to contact your local water provider.
Lead service lines are a significant health concern because lead can leach into drinking water, especially if water is corrosive or if pipes are old. The EPA and CDC recommend that homes with lead service lines use filters certified for lead reduction or consider replacing the line.
Finding your utility's inventory
Massachusetts utilities are required to make their inventories available to the public. You can contact your local water system directly to ask about your property's service line status, or check your utility's website for published inventory data. The state may also have posted aggregate compliance information on its website.
Next steps for residents
- Contact your water utility and ask whether your address is served by a lead service line.
- Request a water test if you're concerned about lead levels; your utility can provide guidance or may offer free testing.
- Check your utility's website for the published lead service line inventory.
- Talk to your pediatrician or call the CDC hotline (1-800-CDC-INFO) if you have health concerns, especially if you have young children.
