The Tijuana River flows through Mexico and empties off California, carrying pathogens and chemicals and threatening public health
Raw sewage and runoff in the Tijuana River is exposing communities at the US-Mexico border to an unusual and noxious brew of pathogens and toxic chemicals, according to a report released this week.
Billions of gallons of sewage flow through the river, which winds north from Mexico through California and empties into the Pacific Ocean, containing a mix of carcinogenic chemicals including arsenic, as well as viruses, bacteria and parasites, according to public health researchers at San Diego State University, who published the report.
