The Aliso Canyon gas leak broke out near Porter Ranch nearly four years ago. On Tuesday a City Councilman called for an investigation of a different underground gas field after troubling images surfaced on video.
The video uses a special infrared camera to show a duck swimming in the Ballona Wetlands amid bubbles of gas. An environmental advocacy group, Food and Water Watch, says the gas is methane. They released the video this week to push for the city to investigate the underground gas storage field in nearby Playa del Rey.
Southern California Gas Co. says the gas surfacing in the wetlands is naturally occurring and unrelated to its underground natural gas storage field in Playa del Rey.
