The Imperial Beach shoreline was closed Saturday to prevent exposure to sewage runoff from the Tijuana River, announced the Department of Environmental Health.
The area by the north shoreline at the Tijuana Slough National Wildlife Refuge was already closed due to this problem.
Now the closure has been extended because ocean currents moving north have raised concerns that sewage runoff will contaminate the ocean water at Imperial Beach, according to the department.
Signs that warn of sewage-contaminated water will remain in place. The department will remove the signs once field measurements show the ocean water is safe again for recreational use.
