San Luis Obispo County health officials have removed beach warning signs and say the water is safe in Oceano a day after a sewage spill.
Testing of ocean water samples taken Wednesday were within state water-quality standards, the county Public Health Department announced Thursday.
On Wednesday, between 160,000 and 180,000 gallons of partially treated sewage was released into the ocean at Oceano Beach between 4 and 7:30 a.m.
The release occurred after the chlorination system at the South San Luis Obispo County sewage treatment plant failed. Chlorination systems are used to decontaminate effluent before it is discharged.
The spill occurred via the plant’s discharge pipe 4,000 feet offshore in 60 feet of water. The release stopped when the chlorination system was restored.
This was the second sewage spill in the county in as many days. On Tuesday, 100 gallons of sewage spilled into Stenner Creek in San Luis Obispo because of a blocked sewage line.
