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.

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 Los Angeles. Nominate your area to be included, and follow this project for updates.

Boston: Older pipes, more leaks

Boston's aging infrastructure is prone to corrosion and leaks. Our readings indicate an average of about one leak for each mile we drove.

Indianapolis: Newer pipes, fewer leaks

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

Staten Island, New York

New York City also 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.

Google Street View car

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.

Help us expand! Your nomination helps us plan where to map next, and shows local utility companies and regulators support for reducing leaks.
