Findings

Our readings indicated an average of about one leak for every 10 miles we drove.

Readings are from October 2014 and may not reflect current leaks, due to repairs or other changes.

If you ever smell gas, or have any reason to suspect a problem, experts say to immediately exit the building or area, then call the authorities. For more see the Vermont Gas Systems safety page.


About Burlington's natural gas infrastructure

  • Utility: We mapped in areas serviced by Vermont Gas Systems, which is a relatively small distribution system built more recently than others in New England. Most leaks don’t pose an immediate threat to safety or health, but some can. We have shared this data with Vermont Gas Systems.
  • Pipe materials: The vast majority (74%) of Vermont Gas Systems pipes are plastic. Vermont Gas Systems does not report any corrosive or leak-prone piping.
  • Age of pipes: Approximately 7% of the pipes are over 50 years old.

Live in Vermont? Ask state officials to update natural gas leak detection and repair

As the Vermont Gas Systems distribution system ages, more frequent inspections and timelines for repairing and replacing leaky pipes are necessary.
