Several beaches in southern California were closed to swimmers and surfers Wednesday after nearly 8 million gallons of sewage was discharged into the ocean.

FOX 11 in Los Angeles reported that beaches in Long Beach and Cabrillo Beach in San Pedro would remain closed because of the millions of gallons of contaminated material that entered the ocean.

On Monday afternoon, the Los Angeles County Department of Public Health announced that sewage was discharged from an unspecified location at about 6 a.m.

As a result, untreated sewage was sent into the Dominguez Channel, which leads to an area near Cabrillo Beach. Eventually, the sewage flow was halted, the station reported.

Residents were already warned to avoid ocean water because of bacterial runoff from recent torrential rains.
