Ocean Advisory Issued at 28th Street in Manhattan BeachJul 30, 2021 10:26AM ● By Jeanne Fratello
An ocean "advisory" has been issued for the beach at 28th St. in Manhattan Beach near the storm drain. That advisory, however, is believed to be part of a normal fluctuation in bacteria levels, not necessarily connected to the recent Hyperion waste treatment plant spill.
An advisory is issued when bacterial levels exceed state standards and may cause illness. It is different from a beach closure, which is issued when the water has been directly contaminated by sewage or other health hazards. During an advisory, the beach remains open but beachgoers, especially those with health issues, are urged to use caution.
"[This advisory is] very likely due to day-to-day fluctuations in ocean water bacteria levels. At this time, there is no reason to suspect these increases in beach water bacteria are due to the recent sewage discharge at Hyperion," read a statement from the Los Angeles County Department of Public Health.
Bacteria levels can increase significantly during and after rainstorms, as contaminants within the runoff enters the ocean. Manhattan Beach experienced a small amount of rain on Tuesday, July 27.
Bacteria levels may remain elevated up to three days depending upon the intensity of the rain and the volume of runoff. LACDPH recommends that beach users avoid contact with ocean water for three days after significant rainfall, especially near flowing storm drains, creeks and rivers.
An earlier advisory was issued, and then rescinded, for 28th Street in Manhattan Beach on July 13 following the July 12 Hyperion spill. El Segundo and Dockweiler beaches were initially closed following that spill; they currently remain under advisory.
In general, beachgoers are urged to be careful of swimming, surfing, and playing in ocean waters around discharging storm drains, creeks, and rivers.
The Beach Cities of Redondo Beach, Manhattan Beach and Hermosa Beach, Palos Verdes Estates and Rancho Palos Verdes jointly collect water samples within their cities, once a week throughout the year.
