Thousands of gas meters leaking in California

"An investigation by KCRA in Sacramento revealed that Pacific Gas and Electric had surveyed homeowners’ gas meters over the last three years and marked thousands of leaks across Northern California." 

"However, a company whistleblower says PG&E never told homeowners and two years later many homes continue to leak. PG&E insists there is no danger because the leaks are small. In response, lawmakers and watchdog groups say the leaks should be fixed immediately."
