City Maps of Gas Leaks

Every year, utilities in Massachusetts report information about gas leaks in their territories to the Department of Public Utilities. HEET uses the reports to create the maps and information below.

The maps are snapshots in time as of the last day covered by the report.  Any one leak could have been repaired since or new ones developed. 

You can use these maps to zoom in on your home, school, or business to find local gas leaks.

Google Maps places map pins on buildings.  The leaks are on public streets, not inside buildings.

For information on how to reduce gas leaks in your town or across the state, read our action manual.

Always call if you smell gas. And. . .  there’s much more information out now about leaks and where those leaks are located. Gas companies are asking the public not to use a list or map to call in leaks. That information is known by the utilities and is part of a repair or replacement plan, often in coordination with cities and towns. Utilities can’t fix those right away without significant disruption and are required to follow a plan of prioritization.

Utilities are aware of high-emitter leaks but are not able to address all of them now. If you are concerned about a particular leak, please contact your town to find out when it’s scheduled for repair.

That said, if you smell gas, please call it in immediately.

Please also call if you notice a change in an existing leak—smells stronger or smell has moved.
