The beach closure at the Coronado Shoreline due to water contamination has been expanded to include North Beach and the Coronado Lifeguard Tower. The Tijuana River is flowing and reaching recreational waters, causing the ocean water to contain sewage that may make people ill.

Why it matters

Ongoing sewage contamination in the San Diego region is a persistent public health issue, as it can lead to beach closures, restrict recreational activities, and pose risks of waterborne illnesses. This latest expansion of the Coronado Shoreline closure highlights the need for continued monitoring and infrastructure improvements to address the source of the pollution.

According to the San Diego County Department of Environmental Health and Quality, the water contact closure was in addition to closures already in place for the Tijuana Slough, Imperial Beach and Silver Strand Shorelines, and Avenida Lunar.
