The Tijuana River sewage crisis has been raging for decades. It’s one of the most pressing environmental emergencies in the region. Southern California beaches are forced to close regularly due to pollution from the river, and Tijuana residents suffer the consequences of poor sewage and water infrastructure that puts their health at risk.
