As a massive natural gas leak just north of Los Angeles continues to surge, plaintiffs attorneys across the country are filing suit over medical problems and lost property values.

The Oct. 23 discovery of a leaking well at an Aliso Canyon natural gas storage facility north of downtown Los Angeles has forced about 2,500 households in a residential area called Porter Ranch to temporarily relocate to area hotels. Two schools have closed, residents have complained of nosebleeds and nausea and, on Jan. 6, California Governor Jerry Brown proclaimed a state of emergency for Los Angeles County. Well owner Southern California Gas Co., a subsidiary of San Diego’s Sempra Energy, has so far been unable to stop the leak.
