City snapshots: Help us expand
The cities where we tested a new way to measure natural gas leaks are a cross-section of America’s urban geography. The maps underscore the persistent and widespread challenge of leaks. They also show the results when utilities and regulators dedicate resources to fix the problem. Beyond this pilot project, EDF hopes that utilities will publish their own maps to show where they have made repairs and where new leaks are found.
The project is still in demonstration mode, using a handful of specially-equipped Google Street View cars. In the coming months, look for maps from more cities. Nominate your area to be included, and follow this project for updates.
Boston’s aging infrastructure is prone to corrosion and leaks. Our readings indicate an average of about one leak for each mile we drove.

Burlington is a smaller system built more recently than others in New England. Our readings indicate an average of about one leak for every 10 miles we drove.

Chicago’s partially updated system is still among the oldest in the country. Our readings indicate an average of about one leak for every three miles we drove.

Of the cities we’ve mapped so far, Indianapolis has the lowest number of leaks. Our readings indicate an average of about one leak for every 200 miles we drove.

NewLos Angeles Area, CA
We mapped three cities in the Los Angeles Area: Chino, Inglewood and Pasadena. In the areas surveyed we found one leak for roughly every four to five miles we drove.

Staten Island, NY
New York City has an older infrastructure that includes corrosion-prone cast iron pipes. Our readings indicate an average of about one leak for each mile we drove.

More than half of Syracuse’s pipes are more than 50 years old. Our readings indicate an average of about one leak for every two miles we drove.

Google Street View mapping cars are a powerful tool to gather data and make it widely available. This pilot project showed for the first time that complex sensor data can be translated into insight about leaks.
