The South Bay in San Diego County is the site of one of the nation’s worst environmental disasters. Fifty million gallons of untreated sewage and industrial chemicals flow daily into the Tijuana River and out of Imperial Beach. New research connects the waste to worsening air quality, which has been linked with headaches, skin infections and gastrointestinal problems in the local population. We’ll talk about why solutions could be years away.
