    The release of 2 million to 4 million gallons of untreated sewage into the Dominguez Channel in Carson has forced the closures of some beaches. For most of the shoreline in Long Beach no signs were visible today before 1 p.m. and beachgoers were enjoying the first day of sunshine in a while.

LONG BEACH, Calif. >> Beaches along the south Los Angeles County and Orange County coast were closed today due to a spill of untreated sewage, authorities said.

A sewer main line failed Thursday afternoon in the city of Carson and 6 million to 7 million gallons (22.7—26.5 million liters) of sewage was discharged into the Dominguez Channel, a waterway that empties into Los Angeles Harbor, LA County authorities said.

The Long Beach city health officer, Dr. Anissa Davis, ordered a temporary closure of all swimming areas of the city’s approximately 7 miles (11.3 kilometers) of beaches.

The Los Angeles County Department of Public Health closed Cabrillo, Point Fermin, White Point Park, Royal Palm and Rancho Palos Verdes beaches. Seal Beach was among areas closed in neighboring Orange County.

The 70th annual Polar Bear Swim that usually draws hundreds of people to Cabrillo Beach in San Pedro for a New Year’s Day plunge was canceled.

Authorities said the beaches would remain closed until testing of water samples shows bacteria levels are within state standards.

LA County Supervisor Janice Hahn called for an investigation by the county Sanitation District to determine whether the spill was caused by “aging or faulty infrastructure.”

“A sewage spill of this magnitude is dangerous and unacceptable, and we need to understand what happened,” she said in a statement.
