South San Diego is facing a crisis that’s been overlooked for far too long. This video uncovers the ongoing environmental disaster caused by the Tijuana River, which has carried billions of gallons of toxic sewage from Mexico into the U.S., impacting communities like Imperial Beach and South San Diego. We explore how this pollution has led to chronic beach closures, health issues, and ecosystem damage, and why decades of political gridlock and cross-border complexity have made fixing it so difficult. With new federal attention, international collaboration, and a startling 2025 study revealing that the pollution is now airborne, there may finally be hope for change. This is a story about more than just water—it’s about justice, public health, and whether San Diego’s most vulnerable communities will finally get the protection they deserve.
