Tijuana River Valley Sewage Community Survey Results Complete
The results are in from a second, larger community survey where 2,099 people in San Diego’s South Bay completed questionnaires about their experiences living, working or recreating near the Tijuana River Valley and polluted beaches from the border to Coronado.
Overall, the results show people in the area have concerns about air quality and drinking water and have made changes to their daily lives in response to the sewage crisis.
In November 2024, the Centers for Disease Control and Prevention’s (CDC) Agency for Toxic Substances and Disease Registry (ATSDR) asked San Diegans in the County’s south region about how the sewage flows had impacted their lives.
The survey is called the Assessment of Chemical Exposures (ACE). It is used by the ATSDR to quickly assess how many people were exposed to harmful agents and if they are experiencing symptoms or have any immediate needs.
The information collected in the South Region includes anecdotal stories about changes to everyday life along with physical and mental health impacts. The results are being used to determine what steps and support further efforts to address the sewage crisis with local, state and federal partners.

The results of ACE confirmed the results of the Community Assessment for Public Health Emergency Response (CASPER) completed last October while expanding participation to more impacted communities and to the individual level instead of households
Community members reporting physical symptoms and mental health issues they felt were caused by the sewage crisis were prevalent in both surveys. Concerns about the safety of the community and of the safety of tap water for drinking were also common to both surveys.
Ongoing collaboration
The County is leading an ongoing collaboration with multiple agencies, bringing them together for regular meetings to address air and water issues related to the Tijuana River Valley crisis.
Based on assessment results, the County has identified the following priority actions to address with collaborating partners.
- Communication: Share health and resource information in multiple formats including social media and via community outreach workers.
- Drinking Water: Educate the community about how household drinking water is tested and not sourced from the Tijuana River.
- Mental Health Concerns: Promote mental health services and resources.
- Healthcare Providers: Update providers on surveillance activities and ongoing projects.
- Pet Concerns: Engage with vets, hospitals and area animal organizations.
More actions around the sewage crisis
Expected to take about two years, another public health assessment from the Centers for Disease Control and Prevention (CDC)/Agency for Toxic Substances and Disease Registry (ATSDR) will evaluate the Tijuana River Valley for hazardous substances, health outcomes, and community concerns.
This new public health assessment will look at environmental data from government agencies and researchers, review air, surface water, sediment, soil, fish tissue, and odor complaint data, identify information gaps and uncertainties where there is not enough data to determine health risks and make recommendations to agencies, community members, and others to prevent and minimize harmful exposures.
