A survey addressing the impact of Tijuana River sewage pollution on San Diegans has reached a significant milestone, with over 1,000 responses collected. This marks the halfway point toward the target of 2,000 completed surveys. The achievement was reached earlier than expected, and residents who have not yet participated are encouraged to do so.

Dr. Seema Shah, County Interim Deputy Public Health Officer, expressed gratitude for the public's response: "We are really grateful to the public for this response." She emphasized the importance of continued participation: "There are still many voices to be heard so I ask anyone who is eligible to please take 20 minutes to share their experiences."

The Assessment of Chemical Exposures (ACE) survey targets individuals living or working in areas most affected by sewage pollution. It covers physical and mental health impacts, healthcare usage, medical history, and pet health.

Launched on October 21 in collaboration with the federal Agency for Toxic Substances and Disease Registry—a CDC branch—the ACE survey follows a similar initiative known as CASPER. Conducted during the weekend of October 17, CASPER focused on Imperial Beach and Nestor communities through household visits and interviews.

Both surveys aim to assess lifestyle and health effects related to sewage issues in southern San Diego County. The ACE survey is accessible online until November 22 for those residing or spending time around Tijuana River Valley, Nestor, up to Coronado.

Participation is confidential and voluntary, taking approximately 20 minutes to complete. Parents can also submit responses on behalf of their minor children.
