CARSON (CBSLA) – More beaches in Southland were added to a “prohibited” list due to a sewage spill in Carson last week.
The spill resulted in seven beaches now being closed. The two most recent additions include Surfside Beach and Sunset Beach. Previous closings include Cabrillo, Point Fermin, White Point, Royal Palms, and Rancho Palos Verdes Beaches.

More than 8 million gallons of untreated wastewater spilled into the Dominguez Canal last Thursday. Cloudy, brown water also poured into several quarters.
“I couldn’t sleep in my bedroom. I had to go to another room at the back to sleep. It was all in my house, ”said Najah Najiy, a neighbor. “Headache, nausea, it comes unexpectedly.”
Los Angeles County Sanitation officials say they are still trying to figure out what caused the sewage pollution. The crews managed to stop the leak late on Friday evening. A department spokesman said they were aware that the 1.2 meter diameter was old and that a replacement sewer was under construction at the time of the leak.

“We really have to research further. This is an older sewer. This will be installed in the 1960s. We have a program to monitor the condition of the sewers in our system. This was something we knew was nearing the end of its life, ”said Bryan Langpap of the LA County Sanitation District.
The LACSD posted an updated statement on the incident on its website on Sunday evening, which can be viewed in full here.
Part of the statement states that during the cleanup, cleaning up of the debris in the area of the spill is almost complete and that a number of tests have been carried out.
“The night the leak started, the monitoring for hydrogen sulfide in the vicinity of the leak was completed and nothing was detected. The Air Quality Management District has two measuring stations for the air quality in the area. Comparing the hydrogen sulfide levels for two weeks prior to the spill with those after the spill shows no difference – the values range from about 0.5 to 6 parts per billion.
Work continues around the clock to dig and repair the broken sewer. Almost all of the debris has been removed. We are now attempting a video inspection of the sewer downstream of the collapse to assess whether this section of the sewer is safe to run off. If it’s safe, we’ll restore flow to the sewers.
We are still working on a permanent repair. On Friday we ordered pipelines with which the existing sewer becomes “slipline”. With slip-lining, a 42-inch pipe is installed in the existing 48-inch sewer, which provides a new, corrosion-resistant pipe for transporting the wastewater. We expect the 42-inch pipe to be shipped this week and then the permanent repair to begin. Once the permanent repair is complete, the area can be restored, including reopening the 110 adjacent lanes. “
