The Centers for Disease Control and Prevention has agreed to investigate the potential health risks associated with sewage flowing into the Tijuana River and across the border into southern San Diego County. In a letter dated last week, CDC Director Mandy Cohen said its Agency for Toxic Substances and Disease Registry would collect environmental sampling data from federal, state and local health agencies regarding health risks stemming from contaminants in the water, soil and air. Cohen wrote that the typical review process of gathering data, determining if the data is sufficient, then determining whether exposures to the contaminants may harm health can take six to 12 months. Cohen said the timeframe of the review process depends on "the format and complexity of the data received."
