SAN DIEGO—Select South Bay residents began receiving visits from the U.S. Centers for Disease Control Thursday as the federal agency is partnering with the county in a health assessment to determine the impact of the Tijuana River Valley sewage pollution crisis.
The county and CDC are working together on a Community Assessment for Public Health Emergency Response or CASPER. A total of 210 households were selected from a larger 30-block section of homes near the border to participate in the survey.
