Officials: California Gas Leak Permanently Capped

Officials said Thursday that a ruptured natural-gas well in Porter Ranch, California, has been permanently sealed, four months after what has been called the worst leak of its kind in U.S. history. Thousands of nearby residents who forced to evacuate will now be able to return home, as crews successfully injected the well with heavy fluids and cement. Some have assured residents that the methane fumes pose no permanent health risks, but other state and local officials have expressed concerns that contiminants may linger in the area.
