"SAN DIEGO — The United States and Mexico have signed an agreement outlining specific steps and a new timetable to clean up the longstanding problem of the Tijuana River pouring sewage across the border and polluting California beaches, officials from both countries announced Thursday.

Billions of gallons of sewage and toxic chemicals from Tijuana have polluted the Pacific Ocean off neighboring Southern California, closing beaches and sickening Navy SEALs who train in the water. That’s despite multiple efforts and millions of dollars that have been poured into addressing the problem over decades, including under the first Trump administration.

“There is a great commitment by the two countries to strengthen cooperation,” Mexico’s Environmental Secretary Alicia Bárcena said Thursday after meeting with Environmental Protection Agency Administrator Lee Zeldin in Mexico City for the signing of the memorandum of understanding."
