I was reading the NYTimes web newsletter, on pollution of the air and ocean fromm sewage flow from the Mexican Tijuana River into the CA Pacific ?

09 June 2025 1 1K Report

The article stated the sewage caused water and airborne bacteria to develop ; makking breathing difficult in the CA border beach town. Is such possible ?

Gerardo Ruiz

Hello Carmel Dylan:

Yes, airborne exposure to bacteria and pollution from sewage runoff is a real concern at the California-Mexico border. Ongoing binational infrastructure issues and climate change-driven extreme weather are worsening the problem. Agencies like the EPA and California health departments monitor the situation, but long-term solutions require major infrastructure investments.

Best regards.
