SAN DIEGO–The County of San Diego Department of Environmental Health has extended the existing water contact closure area at the Tijuana Slough National Wildlife Refuge and Border Field State Park shoreline to include Imperial Beach, Silver Strand and Coronado shorelines.

Sewage-contaminated runoff in the Tijuana River has been entering the Tijuana Estuary as a result of recent rainfall. Observations indicate contamination of ocean water now extends from the U.S. – Mexico border to Coronado.

Signs warning of sewage contaminated water will remain in place until field measurements indicate the ocean water is safe for recreational use.
