The San Diego County Board of Supervisors unanimously approved a proposal Tuesday to request $1.4 million in state funding for a comprehensive contamination study of the Tijuana River Valley. The move is part of a renewed effort to designate the area as a federal Superfund site, which could unlock billions in federal funding for cleanup efforts. …  If approved by the state, the funds would be allocated to the San Diego Regional Water Quality Control Board to conduct the study.
