SAN DIEGO–The County of San Diego Department of Environmental Health has extended the existing water contact closure area at the Tijuana Slough and Imperial Beach shorelines north to include the Silver Strand Shoreline.  

Sewage-contaminated runoff in the Tijuana River has been entering the Tijuana Estuary and observations indicate contamination of ocean water now extends from the International Border north to the Silver Strand shoreline.  

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