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

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, south of Avenida Lunar. 

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