Clean Border Water Now

Join Us to Heal Our Coast and Communities

The Pacific coastline along the U.S./Mexico border is steeped in rich multicultural identities, contains immense biodiversity, and contributes high economic value to both countries. Yet, this region is plagued by severe pollution that threatens public health, limits coastal access, hurts ecosystems and wildlife, and jeopardizes local economies and national security. 

Every day, millions of gallons of untreated sewage, industrial waste, and trash flow across the U.S./Mexico border, impacting 20 miles of international coastline and hundreds of thousands of people who live in, work in, and visit this region. The toxic flows cause beach closures in South San Diego County and widespread illnesses on both sides of the border.

This is a grave public health crisis and one of the most significant environmental justice issues in the United States.  

It will take all of us standing up, adding our voices, and demanding action to create the social movement necessary to end this crisis.


About The Program

CBWN aims to address the sewage, trash, and industrial waste that plagues our ocean, waves, and beaches in the U.S./Mexico border region. We do this by working alongside impacted community members, partners, and coalitions to raise awareness through outreach and education, while impacting policy at all levels of government through our advocacy work.

CBWN is a volunteer-led, staff-supported program. The CBWN Committee meets every second Monday of the month at 6:00 pm.

This is a public health and environmental justice emergency
