County officials Wednesday extended the water contact closure at the Tijuana Slough shoreline to include the Imperial Beach 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 to 500 feet north of Carnation Avenue in Imperial Beach.
Signs warning of sewage-contaminated water will remain in place until sampling results indicate the ocean water is safe for recreational use, according to the County of San Diego Department of Environmental Health and Quality.
