Toxic Sewage Crisis: A Border Disaster

Millions of gallons of sewage flow from the U.S.-Mexican border into the Pacific Ocean, creating an environmental and public health crisis. Decades of neglected infrastructure have led to severe contamination of waters in San Diego and Tijuana, severely impacting local communities and tourism. Ongoing repairs promise hope for resolution.

Each day, millions of gallons of sewage cascade through a canyon and into the Pacific Ocean just south of the U.S.-Mexican border. Summer swells push this toxic brew north, affecting San Diego waters.

Meanwhile, treated and untreated sewage from the Tijuana River flows into the sea north of the border. City officials describe this situation as the nation's biggest unnoticed environmental and public health disaster, marked by a severe impact on Imperial Beach.

The International Wastewater Treatment Plant, overworked and underfunded, has buckled under increased volumes. Crucial repairs and significant investments are ongoing, with Baja California promising to rectify the infrastructure by 2027. Across the border, sanitation efforts and massive federal funding are set to expand capacity but need further investment to cope with the crisis.
