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.
