Additional influxes of storm-driven sewage out of Baja California prompted authorities Monday to expand an earlier border-area pollution warning to include the entire ocean shoreline of Imperial Beach.
Contamination carried into the Pacific via the Tijuana River has drifted to the north past Border Field State Park and Tijuana Slough National Wildlife Refuge, according to the San Diego County Department of Environmental Health.
Signs warning of contamination hazards will stand along the affected beaches until follow-up testing deems them safe again for recreational uses, the DEH advised.
