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

Readings are from April through August 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 National Grid safety page.
