Our readings indicated an average of about one leak for every 60 miles we drove within the study area.

Readings are from March through April 2016 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 authorities. For information about City of Mesa Municipal System, see their safety page.
