San Diego, CA–The County Department of Environmental Health and Quality has extended the existing water contact closure area at the Tijuana Slough shoreline north to include the Imperial Beach shoreline.

Water sample results indicate contamination of ocean water now extends from the International Border to 1000 feet north of Carnation Avenue in Imperial Beach.

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