The County of San Diego Department of Environmental Health on Friday extended an existing closure at the Tijuana Slough north to include the Imperial Beach shoreline.

Sewage-contaminated runoff in the Tijuana River has been entering the Tijuana Estuary, officials said. Sample results indicate contamination of ocean water now extends north to IB.

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

For more information on the Tijuana River, call the U.S. International Boundary & Water Commission at 619-662-7600.
