After a day of taking samples and cleaning, officials think a sewage spill in Huntington Harbour on Thursday might have been less extensive than previously believed.
An estimated 60,000 gallons of sewage was the original estimate. But Anthony Martinez, water quality program manager with the Orange County Health Care Agency, said the actual amount spilled might have been less.
Preliminary information shows the spill was caused when a main sewer line in nearby Stanton got blocked, causing sewage to seep out of the nearest manhole, he said. It was not known what caused the blockage, but tree branches or roots are often at fault, he said.
On Thursday, the Environmental Health division of the county Health Care Agency closed the harbor area, which encompasses Anaheim Bay, Sunset Aquatic Marina, Portofino Cove, Anderson Street Marina, Mother’s Beach and Admiralty Drive.
