The stench of sewage drifting across Southern California is now a full-scale public health crisis affecting tens of thousands of residents living near the Tijuana River, where toxic gases linked to raw sewage have been tied to nausea, respiratory illness, and even neurological symptoms.
A new Associated Press report details how communities along the U.S.-Mexico border are exposed to dangerous levels of pollution from decades of untreated wastewater flowing north from Tijuana on a daily basis. Since 2018 alone, more than 100 billion gallons of sewage mixed with industrial chemicals and trash have entered the river system.
