City Maps of Gas Leaks

Every year, utilities in Massachusetts report information about the natural gas leaks in their territories to the Dept. of Public Utilities. HEET used two years of 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. Using these maps, you can zoom in on your home, school or business to find local gas leaks.

The data from the 2014 and 2015 reports is in different layers on these maps.  Google Maps aren’t exact.  If you’re worried about a leak, click on the map pin to double-check the address. 

“Missing”  leaks are leaks listed as unrepaired in the 2014 reports, which are not mentioned in the 2015 reports, either as repaired or unrepaired.  HEET is investigating these leaks further.

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