Mexico’s Sewage Pollution Crisis Sparks Trump’s Concerns

In a recent post on Truth Social, President Donald Trump called out Mexico for creating what he described as a serious sewage pollution issue affecting the United States. He labeled this situation a “real threat” to residents in Texas and California, attributing it to Mexico’s ongoing challenges with water and wastewater management.

Mexico has been struggling to meet its obligations under the 1944 Water Treaty, which has only worsened due to a prolonged drought that has critically depleted water in its northern reservoirs. The country currently owes over 800,000 acre-feet of water from the Rio Grande to the U.S.

Back in April, in response to pressure from U.S. officials, Mexico made a deal to guarantee Texas farmers access to clean water from the Rio Grande. As stipulated in the treaty, Mexico is also required to supply 1.75 million acre-feet of water over a five-year period.

At the same time, inadequate wastewater systems in cities like Tijuana, Nogales, and Nuevo Laredo are discharging between 30 million to 150 million gallons of either raw or poorly treated sewage into the U.S. daily. This contamination is significantly affecting California’s coastline and the Rio Grande in Texas, posing a long-term public health crisis in border areas. Millions in Mexico are facing unreliable access to water and sewage services, while major cities deal with rationing and leaks, highlighting a dire need for massive infrastructure investments that the country cannot currently afford.

“Mexico must address its water and wastewater problems immediately. This is a real threat to the people of Texas, California, and the United States of America!” Trump asserted on Wednesday.

Accompanying Trump’s post was a video stating that “Mexico is sending millions of gallons of untreated sewage into the Tijuana River.” It went on to mention that major discharges are often due to operational issues at Tijuana’s main sewage treatment plant, creating health risks for communities like Imperial Beach and Coronado.

This tweet echoed a July meeting where both nations signed a memorandum aimed at tackling the sewage flow from the Tijuana River Basin. The agreement is aimed at encouraging cooperation through organizations like the U.S. Environmental Protection Agency (EPA) and Mexico’s Secretariat of Environment and Natural Resources (SEMARNAT).

“Both countries have great determination to strengthen cooperation,” said Mexican Environment Secretary Alicia Bárcena following a meeting with EPA Secretary Lee Zeldin.

Zeldin added, “The Trump Administration is proud to have delivered this major environmental and national security victory to Americans in the San Diego area.”

Under this agreement, Mexico committed an additional $93 million towards wastewater infrastructure improvements, promising to focus on completing these projects by 2027. With tens of millions of gallons of contaminated water flowing from the Tijuana River basin into the Pacific Ocean each day, the situation varies greatly, particularly after storms, overwhelming existing systems and treatment facilities.

The U.S. EPA has noted that these cross-border flows are negatively impacting both water and air quality in San Diego County communities. This pollution isn’t the result of intentional dumping but stems from a long-standing infrastructure crisis, characterized by malfunctioning and inadequate sewage systems, rapid urbanization, frequent breakdowns, and limited treatment capacity. Heavy rains exacerbate this issue, as rainwater mixes with sewage and waste, forcing more water into a system that can’t manage it.

Consequently, South County beaches often face closures, with public health warnings becoming increasingly routine. Prolonged infrastructure improvements on either side of the border have resulted in escalating frustration among various officials.

As a response to persistent odors and air quality issues, the San Diego County Air Pollution Control District recently distributed 200 air purifiers to affected communities in South Bay.

In another Truth Social post, Trump reiterated demands regarding this matter, stating, “Mexico continues to violate our comprehensive water treaty, and this violation is severely harming our beautiful Texas crops and livestock. Mexico still owes more than 800,000 acre-feet of water to the United States.”

This has hit Texas farmers hard, with many reporting dreadful outcomes for crops like citrus and sugar due to sewage contamination. The Rio Grande Valley, in particular, is facing extreme water shortages, which is affecting agriculture and local economies.
