US-Mexico border: 100 billion gallons of toxic sewage creating a 'public health crisis'

The U.S.-Mexico border region faces a public health crisis as billions of gallons of contaminated sewage flow from Mexico into San Diego, California, according to a newly released report.

“South San Diego County is in a total state of emergency related to transboundary pollution, and this is a public health ticking time bomb,” Imperial Beach Mayor Paloma Aguirre told ABC News. “We are living in conditions that nobody in this great nation should be living in.”

The Tijuana River – which has been classified as an impaired water body, according to the U.S. Clean Water Act – flows north for 120 miles from Mexico to California before reaching the Pacific Ocean on the U.S. side of the border in the Imperial Beach, San Ysidro and Coronado coastal areas.

Over the last five years, 100 billion gallons of untreated sewage, industrial waste and urban runoff have been dumped into the Tijuana River, according to the International Boundary and Water Commission.
