The San Diego Regional Chamber of Commerce has released a comprehensive binational report outlining a five-pillar strategy to address the Tijuana River contamination crisis. The report, commissioned by the Prebys Foundation, was authored by Doug Liden, a former U.S. Environmental Protection Agency official, and Maria Elena Giner, former commissioner of the US International Boundary and Water Commission (IBWC). The report found that a federally owned wastewater treatment plant at the heart of the crisis received only $4 million in maintenance funding over an 11-year span, while dry-weather sewage flows across the U.-Mexico border surged to record levels. It also revealed that Mexico has delivered approximately $51 million of a $144 million infrastructure commitment under a 2022 binational agreement called Minute 328, while the United States has committed $650 million toward rehabilitation and expansion of the same treatment facility. The study suggests five mutually reinforcing pillars: reliable infrastructure funding, modernized operations and maintenance, enhanced governance, and long-term water management and reuse planning.
