On Sept. 7, 1993, the San Diego City Council declared a state of emergency regarding the discharge of raw sewage it said was coming from Tijuana, Mexico, and polluting the international border.
More than 30 years later, the San Diego City Council renewed the state of emergency on Feb. 27 over an ongoing issue that has been traced back to 1934.
In the past five years, the International Boundary and Water Commission stated that more than 100 billion gallons of untreated sewage, industrial waste and urban runoff have been discharged into the Pacific Ocean from the Tijuana River.
