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 Imperial Beach shorelines north to include the Silver Strand shoreline.

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 international border through Silver Strand.

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