The Imperial Beach shoreline was closed Sunday by San Diego County health officials, who said it was due to sewage flowing north from Mexico.
The decision was reached Sunday after observations indicated that sewage-contaminated runoff might be migrating north from Mexico as a result of the recent rainfall and associated ocean currents and wind, according to officials.
Contamination of ocean water at Imperial Beach was suspected. Signs warning of sewage-contaminated water will remain in place until field measurements indicate the ocean water is safe for recreational use.
