Health officials have begun conducting a second round of community health assessments in South Bay neighborhoods bordering the Tijuana River Valley, according to local authorities.
The County of San Diego is partnering with the Centers for Disease Control and Prevention to carry out the Community Assessment for Public Health Emergency Response survey. The effort represents a follow-up to an initial assessment completed in October of last year.
Officials say the current survey is designed to evaluate how residents have been affected by persistent sewage contamination flowing from the Tijuana River Valley. The pollution crisis in the cross-border waterway has been an ongoing concern for communities in the region.
The assessment tool is typically deployed by the CDC to gather public health data in the aftermath of emergencies and disasters affecting local populations.
