On Earth Day 2025, Environmental Protection Agency (EPA) Administrator Lee Zeldin visited San Diego to address the escalating environmental and public health crisis caused by untreated sewage flowing from Tijuana, Mexico, into Southern California waters. This issue has garnered increasing concern due to its impact on local communities and military training areas.
A Persistent Environmental Challenge
For decades, the Tijuana River has been a conduit for millions of gallons of untreated sewage entering the United States. Recent reports indicate that Mexico is discharging approximately 5 million gallons of sewage daily into the river, leading to contamination of U.S. coastal waters. This pollution has resulted in frequent beach closures and health issues among residents and military personnel, including Navy SEALs who train in affected areas.
Zeldin’s Earth Day Mission
Administrator Zeldin’s visit included a tour of the South Bay International Wastewater Treatment Plant and a helicopter survey of the U.S.-Mexico border to assess the extent of the sewage contamination. He also met with Navy SEALs and local leaders to discuss the crisis and explore potential solutions.
“This is not just an environmental issue; it’s a national security concern,” Zeldin stated. “We must ensure the safety of our communities and the health of our service members.”
Calls for Action and Accountability
Local officials and environmental advocates have long urged the federal government to designate the Tijuana River Valley as a Superfund site, which would facilitate cleanup efforts and provide necessary funding. While previous administrations have invested in treatment infrastructure, challenges persist due to aging facilities and insufficient cross-border cooperation.
Zeldin emphasized the need for a collaborative approach, stating, “We are committed to working with our Mexican counterparts to address this issue effectively and protect our shared environment.”
Pros and Cons of EPA Chief Lee Zeldin’s Earth Day Visit to Address the Cross-Border Sewage Crisis
✅ Pros
-
National Spotlight on a Long-Ignored Crisis
Zeldin’s visit brings overdue federal attention to the ongoing sewage contamination from Mexico into Southern California, raising awareness and urgency. -
Advocacy for Military Readiness and Public Health
The contamination affects areas where Navy SEALs train and where civilians live and recreate. By involving military sites in the discussion, the visit frames the issue as both environmental and national security-related. -
Opportunity for Cross-Border Cooperation
The visit could pressure both U.S. and Mexican officials to take stronger bilateral actions, potentially unlocking new funding or infrastructure commitments. -
Political Leverage for Action
With Zeldin tied to the Trump administration, the move appeals to conservative voters demanding border security and environmental accountability—two typically opposing priorities now seen as intersecting. -
Superfund Designation Momentum
It adds momentum to calls for declaring the Tijuana River Valley a Superfund site, which could accelerate clean-up efforts and bring long-term environmental protections.
❌ Cons
-
Limited Immediate Solutions
A symbolic visit may not translate into rapid results. Without binding agreements or allocated funding, it risks being perceived as political theater. -
Strained Diplomatic Relations
Pressuring Mexico too forcefully could worsen bilateral relations or delay cooperative efforts if seen as finger-pointing rather than partnership. -
Military Use as Political Leverage
Critics may view the emphasis on Navy SEAL training grounds as an attempt to militarize the narrative for political gain rather than focus solely on environmental protection. -
Insufficient Addressing of Root Causes
The visit doesn’t directly solve systemic infrastructure failures on the Mexican side or the long-term U.S. failure to manage pollution at the border effectively. -
Partisan Optics
Environmentalists may see the visit as performative, especially coming from a Trump-aligned EPA chief, amid historical skepticism over the administration’s environmental track record.
Conclusion
EPA Administrator Lee Zeldin’s Earth Day visit to San Diego served as both a symbolic and strategic move to highlight the urgent sewage crisis flowing from Mexico into U.S. waters. By framing the issue as not only environmental but also a matter of national security and military readiness, Zeldin amplified the stakes and pushed for stronger federal and cross-border action.
While the visit reenergizes local and national attention to a decades-old problem, the path forward will depend on whether it results in tangible policy commitments—like Superfund designation, infrastructure investment, and deeper U.S.-Mexico cooperation. The crisis underscores a critical truth: environmental neglect knows no borders, and neither should the responsibility to fix it.
