Last month, a trash boom strung across the Tijuana River channel just inside U.S. territory stopped 40 tons of materials during a one-hour rain event – as the trash gets removed and sent to area landfills, another environmental issue has surfaced. Dumps north of the border are having to take in the additional trash coming in from Mexico compounding a critical shortage of landfill space, according to Oscar Romo, director of Alter Terra, a binational environmental group. All of it has to go into a landfill in San Diego.
