Lead Service Lines in Chelsea, MA
What you need to know
Chelsea Water Department, which serves about 38,300 residents through the Massachusetts Water Resources Authority (MWRA), has not yet completed a public inventory of lead service lines in the system.
Lead service lines are pipes that connect the water main in the street to homes and buildings. They were commonly installed before the 1980s. If your home was built or had plumbing work done during that era, there's a reasonable chance your service line contains lead.
Current inventory status
As of now, Chelsea Water Department has not published a detailed breakdown showing how many lead, galvanized, or unknown service lines exist in the system. This doesn't mean the utility is ignoring the issue—it means the inventory work is still underway or results haven't been made public yet.
What Massachusetts requires
Massachusetts law requires all water utilities to develop and implement a plan to replace lead service lines. The state also requires utilities to provide information to customers about lead risk and testing. Even without a complete inventory, your utility is required by federal and state law to have a replacement strategy in place.
Steps you can take now
Test your water. If you're concerned about lead, request a free or low-cost water test from your local board of health or contact Chelsea Water Department directly. Testing is the most direct way to know if lead is present in your home's water.
Find out your service line material. Call Chelsea Water Department and ask what material connects your home to the main. Some utilities have partial records based on construction permits, even if a full inventory isn't public.
Reduce exposure while you wait. If testing shows lead, run water for 30 seconds before drinking it, use cold water for cooking and drinking, and consider a certified lead filter. The CDC has detailed guidance on reducing lead exposure at home.
