US and Mexico sign accord to combat Tijuana River sewage flowing across the border
July 24, 2025
The United States and Mexico have signed an agreement outlining specific steps, funds and a timetable to clean up the longstanding problem of the Tijuana River pouring sewage across the border and polluting California beaches. Environmental Protection Agency Administrator Lee Zeldin and his Mexican counterpart Alicia Bárcena signed a memorandum of understanding on Thursday. Under the agreement, Zeldin said Mexico will complete its allocation of $93 million toward completing infrastructure projects. Mexico also will adhere to a specific schedule. Billions of gallons of sewage and toxic chemicals from Tijuana have polluted the Pacific Ocean off neighboring Southern California over the years, closing beaches and sickening people.
