Sewage Spill in Southern California

Sewage spills, leaks and overflows continue to pollute our beach water and are the 2nd major culprit behind swimming advisories and beach closures issued in this country (stormwater runoff is the first). Another big sewage spill just occurred in Southern California on September 29, 2010.
 
Los Angeles County health officials closed a two-mile stretch of beach just south of Ballona Creek near Marina del Rey last week after raw sewage flowed into the ocean. The closures were ordered after a clog in a sewer main caused a manhole near Centinela Avenue and Sepulveda Boulevard to overflow Wednesday, discharging an estimated 500,000 gallons of raw sewage into a storm drain that leads to Ballona Creek and, eventually, the Pacific Ocean. The spill ranks among the worst in the last two years along the Los Angeles County coastline.

A major sewage spill that has closed a two-mile stretch of beach near Marina del Rey released about 500,000 gallons of raw sewage into a storm drain that runs to Ballona Creek and eventually spills into the ocean, authorities said.

The spill ranks among the worst in the last two years along the Los Angeles County coastline. The beach will probably remain closed for three days.

Residents reported a manhole overflowing with sewage near Centinela Avenue and Sepulveda Boulevard about 12:30 p.m. Wednesday, said Ron Charles, spokesman for the Los Angeles Public Works Department.

City crews dispatched to the scene determined the spill was caused by a blockage in a sewer main.

"The entire backup amount entered an adjacent storm drain, which discharges to the Sepulveda Channel, and ultimately, the Ballona Creek," Charles said in a statement.

Los Angeles and Culver City work crews diverted the flow of sewage, vacuumed up effluent streaming down a hillside and fixed the backup by about 5:30 p.m.

Dr. Jonathan Fielding, director of the Los Angeles County Department of Public Health, called it a "major spill," but did not know how much of the sewage had reached the ocean.

The two-mile stretch of beach south of Ballona Creek will remain closed to swimmers and surfers until at least 3 p.m. Saturday, he said.

In January 2006, 2 million gallons of raw sewage spilled from a Manhattan Beach pumping plant after an apparent power failure. Officials launched a massive cleanup after hundreds of thousands of gallons flowed onto the sand and into the ocean.

The last major spill happened in January in South Gate, when 210,000 gallons of sewage flowed through the L.A. River and emptied into Long Beach Harbor, county records show.

County health officials said they are closely monitoring and testing ocean water near the outlet of Ballona Creek. Beaches will reopen when they pass health tests for two consecutive days.
